[lusty steeple]

So 3.14 times 2 is 6.28

[faint root]

yes

[lusty steeple]

Now divide 321 your c by 6.28

Tell me what it is

[faint root]

51.1

[lusty steeple]

Yes

Ok now hold on to that number

[faint root]

ok

[lusty steeple]

Do you know what the formula is for diameter

[faint root]

no

[lusty steeple]

Ok so the formula for diameter is 2 times r your radius

[alpine sable]

can you help me next?

[faint root]

ok

[lusty steeple]

Sure if I know how

[alpine sable]

if you're done if so ping me

[lusty steeple]

Ok so you have your radius right 51.1

[faint root]

yes

[lusty steeple]

Now times that by 2

[faint root]

102.2

[lusty steeple]

Yes

One thing to pay attention to is if it says to Round

You rounded 51.09 to 51.1 the safest thing to do is to leave it as 51.09 then times that by 2 giving you 102.18

[faint root]

k

[lusty steeple]

Then if it says anywhere to Round then round

[faint root]

k

[lusty steeple]

Now idk if you are supposed to Round or leave it to the tens or hundreds that is all on your class

[faint root]

k

I get it now

[lusty steeple]

Great just make sure on how you put it in

[faint root]

d=2r
C=(2x3.14)xR

[lusty steeple]

@alpine sable

Oops you got it

Oppz

[faint root]

OK LETS GO

[alpine sable]

5c + ( +10 -10) = 29c

Like this math

[lusty steeple]

Ok

That is easy

[faint root]

ok bye ty

[lusty steeple]

Oc

Liebe 10-10=0

[alpine sable]

Ok firstly

don't multipost

cause you left me hanging for 5 mins

oh I asked him earlier

thirdly why's the equation written like that

idk I just made it up

can add a real one

ok it's written weirdly

😅

[lusty steeple]

Liebe for that one it is easy 10-10=0 and 29c/5c= 5.8

[alpine sable]

uh

is it like that for any equation

[lusty steeple]

Some what

[alpine sable]

Like divide the ones with letters always?

[lusty steeple]

Yes

O wait I mistook the question

Did a different formula

Ok so bring all the letter numbers to one side

So it would be 29-5

[alpine sable]

mhm

[lusty steeple]

It is a little hard with that equation

If you do understand the basics

According to pemdos parentheses go first

[alpine sable]

Idk anything abt it

[lusty steeple]

So 10-10

Equals 0

Now move the 5 to the other side

[alpine sable]

So C = 24?

[lusty steeple]

And because you are Pushing the 5 across the equal sign you have to change it to a negative 5

So it is 29-5

Now why it might be a little hard

You moved you 5 over and you now have 0 on the left side and 24c on the right

[alpine sable]

mhm

[lusty steeple]

You have 0 because 10-10=0

[alpine sable]

Can you give me an equation to solve to see if I understood

[lusty steeple]

So 24c=0 so you divide 0 by 24

So the answer would be c=0

[alpine sable]

so you have to decide even though its 1 number?

Devide*

[lusty steeple]

Yes

Let me give a better question

[alpine sable]

If its more than one question

I mean

One answer

What do you devide with

The first number?

[lusty steeple]

5x+30=15x

Try to solve it

[alpine sable]

30=10x

Not done yet

-20/-20

-1

?

Is -1 correct

is this right

[lusty steeple]

Ok sorry I back

[alpine sable]

Mhm

[lusty steeple]

So you got to 30=10x that is right now all you have to do is divide 30 by 10

And that =x

[alpine sable]

-20

[lusty steeple]

3

[alpine sable]

Oh

I thought you put the 30 on the 10 side then divide

Oh nvm

Then I'd have to subtract

[lusty steeple]

Nope because 30 doesn’t have a x you can not add them

[alpine sable]

oh

🤦‍♂️

[lusty steeple]

So it doesn’t matter what side the x is on as long as there is nothing else on that side with the x

[alpine sable]

help

So 30/10 and 10/30?

[lusty steeple]

The last step the 30/10

[alpine sable]

30=10x
x=3?

[lusty steeple]

Yes

[alpine sable]

is this right

[alpine sable]

#rules pls

[lusty steeple]

Your trying to find out x so if 10x is = to 30 that means that x is what ever 10 times # equals 30

[alpine sable]

??

you're not allowed to post when someone is asking

[lusty steeple]

And the discord you joined is a math discord

But let me see

[alpine sable]

I think

Cuz you have 3 toppings

idk if its true

My IQ is really low

[lusty steeple]

Well there is a lot

But it might be 4

[alpine sable]

you have 3 options for toppings

🤷‍♂️

For that week

[fast pond]

sorry

[lusty steeple]

I know how but I don’t have the time to show you how

I need like a hour

Not to explain

[alpine sable]

Can you give another question itself its wrong just say it's wrong I'll wait till ur back

[lusty steeple]

I gonna. E out for a hour

Ok

[alpine sable]

3+4+5÷12?

Nvm

lol

[lusty steeple]

1.15x+30=20x+15

[slow scaffold]

This isn’t a math question but how would I word my final sentence

Would I say “the car depreciated at a rate of 10% per year”?

[alpine sable]

there was a question already please do not interrupt

😁

[slow scaffold]

Sorry

[alpine sable]

Use the formula of a square pyramid surface area thing

hmm I dont really know lol

[lusty steeple]

Sorry the answer is 3

[alpine sable]

😧

was the whole thing wrong

wait

-15x + 30 = 15

[lusty steeple]

@small umbra the answer is 454.03

[alpine sable]

-15x = 15 -30

-15 = -15

[lusty steeple]

15-20=5x

[alpine sable]

-15/-15 = 1

[lusty steeple]

Move 3 to the other side and change the sign

30

15-30

=-15

[alpine sable]

With 3

Which?*

[lusty steeple]

-5x=-15

Sorry the first o e is supposed to be 20

15-20

=-5x

And 15-30=-15

-5x=-15

[small umbra]

For what question

[lusty steeple]

Surface area of pyramid

@slow scaffold say the value of the car depreciated at a rate of 10% per year

[mellow kelp]

1a and b

I have this idk if it’s correct

Idk how to know if it’s going through the z axis

[ionic jewel]

, rotate

[mellow kelp]

Also for the scalar equation how do I find the normal there

I just took the reverse idk

Normally cross product but it’s different here

[alpine sable]

is that just Algebra

expressions

[mellow kelp]

It’s calculus planes

[alpine sable]

what are you supposed to find

[mellow kelp]

The equation of the plane

It’s in the wuestion there

[ionic jewel]

it doesn't inrersect the z axis so it's perpendicular to the xy plane

[mellow kelp]

With those parametric equations tho

Is it correct idk how to do it

[alpine sable]

is what true

[mellow kelp]

Damn nobody knows

[stoic hound]

@mellow kelp for the vector equation of a plane basically you need the plane's normal, and any point in the plane

You know that the plane shouldn't intersect the z axis, which means that its normal should lie within the xy plane

[mellow kelp]

How do I do that when it has to have those parametric equations though

[undone mist]

guys please help me

[stoic hound]

But the given parametric line lies inside the plane, and so is perpendicular to the desired normal

So basically you're looking for a vector that lies in the xy plane, and is perpendicular to the given parametric line

[undone mist]

how is this wrongggggg

[mellow kelp]

So I find the cross product

[stoic hound]

This gives the plane's normal. And you can take t=anything to get a point on the plane

[mellow kelp]

I’m so lost we were barely taught

Is this correct then

[lusty steeple]

@alpine sable #2 is -0.865 Round to -1

[alpine sable]

hh

😞

[stoic hound]

Is n the normal to the plane? I don't think you should have any z component in there

[alpine sable]

This was how I did it @lusty steeple

[mellow kelp]

That’s a separate part I’m focusing on A

Is that a proper equation

[lusty steeple]

Don’t underestimate yourself the problems I am giving you are advanced algebra

[alpine sable]

What did I do wrong

[stoic hound]

A is asking for a vector equation

[mellow kelp]

Yes with those parametrics

[stoic hound]

I think you're writing the equation of the line the plane contains, not the plane itself

[lusty steeple]

Let me check

[mellow kelp]

It says write the equation of the plane

That contains those parametrics and doesn’t intersect the z axis

[stoic hound]

The vector equation of a plane looks like (x-x0)•n=0

Where x, x0, n are vectors

[mellow kelp]

Hm

That must be a different form

[alpine sable]

Yo I did this problem and for the regression function I got y=0.005x. My answer good or nah?

[elder viper]

Duplicate from #help-5

I'm gonna permit myself to ask a question if you don't mind

I'm researching the cardinality of this thing right here

now there are two case scenarios that I'd like to explore

the first one is the one where we essentially work on combinations with repetitions

the main idea is that in order to find the cardinality in this case, we just need to encode a solution into a binary string and that's essentially it

So as you can see in the picture (2, 0, 6) has been encoded in bits

so this technique also known as bars & stars seem to be quite useful when you have repetitions

However, if there wouldn't be any, how would I manage to encode a solution into a binary string

Can sm help me out with this problem

What is confusing for you?

@alpine sable

And what is the question, itself?

K so like how do u do it

[gleaming granite]

are there any other instructions?

is it asking you to solve the equation?

maybe graph the equation

[alpine sable]

^.

Those are the instructions and the other problems similar to it

I did one but I don’t get the others

?

[gleaming granite]

7 is pretty similar to number 8, I think you should be able to apply the same method

[alpine sable]

We did 8 together as a class so I just copied

[gleaming granite]

uh

okay

[gleaming granite]

what are the three points that help you graph a quadratic?

[alpine sable]

A, B, and C

[gleaming granite]

?

what is A,B and C?

[alpine sable]

Like the numbers you get from the problem

The numbers you set aside

Look at the photo you’ll see it there

[gleaming granite]

@alpine sable Do you mean this?

[alpine sable]

Ye

[gleaming granite]

those aren't points

they're the coefficients for a standard form equation

[alpine sable]

Ik about the first two forms but not the third one

[gleaming granite]

Intercept form?

[alpine sable]

Yes

[gleaming granite]

have you been introduced to factoring quadratics?

[unique frigate]

Grade 9?

[alpine sable]

No grade 8

[unique frigate]

Oh

Grade 9 it’s more in depth

[alpine sable]

That’s what I’m doing rn

Oh ok

[gleaming granite]

factor this equation: x^2 + 4x + 4

[alpine sable]

Uhhhhhh

No nvm

I’m doing sm else

I’ve never seen a problem like that

I think I’m learning how to graph quadratics

[gleaming granite]

okay

I'll help you work through then

[alpine sable]

Oh vertex yes

[gleaming granite]

so on a graph of a quadratic what is is the vertex?

[alpine sable]

The vertex would be like the main point right

[gleaming granite]

on this graph where is the vertex?

[gloomy timber]

help

[charred flint]

have you used sec=1/cos yet

[gloomy timber]

no

they just gave me this problem but i dont know what to solve for

[charred flint]

you solve for theta

try doing sec=1/cos

and tan=sin/cos

you usually want to convert these things into sin's and cos's to see if things cancel

[gloomy timber]

so for the top it would be sin(theta)/cos(theta)

right?

and then sec becomes 1/cos(theta)

[charred flint]

right

sec^2 to 1/cos^2

and since it's downstairs you flip it

[heavy canopy]

Is this channel free?

[gloomy timber]

wdym flip it

[gloomy timber]

not currently :)

[charred flint]

like you're gonna have 1/(1/cos^2)

[heavy canopy]

Oh alright

[charred flint]

to bring that 1/cos^2 up to where the tan is, you have to flip it

like 1/(1/3)=3

1/(1/cos^2)=cos^2 on top

[gloomy timber]

?

[charred flint]

yea looks good

[gloomy timber]

then cancel out cos?

[charred flint]

I like to bring the 1/cos^2 up first

so like 2 * sin/cos * cos^2

[gloomy timber]

sin on top?

[charred flint]

not sure what you mean

[gloomy timber]

nvm i get what youre saying

lol i was confused

@charred flint k then i got 2(theta)cos(theta)=1 after simplifying so now i have to simplify into sin(2theta)=1 right?

[charred flint]

yea

[gloomy timber]

uhhh 2(theta)=pi/2

is that right

[charred flint]

yea, does the problem specify that theta is between 0 and 2pi?

[gloomy timber]

no

waiat

yes it does

sorry

[charred flint]

ok cool

pi/2 is the answer

[gloomy timber]

this is the other info for the problem

[charred flint]

gotcha

[gloomy timber]

but dont i have to simpify even more to get rid of the 2 infront of theta

which would make it pi/4

theta=pi/4

[charred flint]

oh woops

there are multiple answers that work then

sin(2theta)=1

so like going from that to 2theta=pi/2, you can also just add multiples of 2pi and it still works

since sin(x)=sin(x+2pi)

so it's more like 2theta = pi/2 + n*2pi

so theta = pi/4, or 5pi/4, or even higher answers but they're above 2pi

so the answers are pi/4* and 5pi/4

[gloomy timber]

wait what where does that 5 come from

[charred flint]

adding pi to pi/4

[gloomy timber]

huh

never done that before

[charred flint]

yea this is pretty tricky

since it's sin(2x) there are more solutions that fit in that 0-2pi interval

[sage jacinth]

right, i know i am pretty late, but you can also write it as pi/2 + n*pi, where n is the number of revolutions around the circle

[charred flint]

ah I meant pi/4 and 5pi/4

[sage jacinth]

oh wait that shouldve gone to the other guy

i forgot that he was the one asking the question

[gloomy timber]

when i simplified 2sin(theta)cos(theta)=1 to sin(2theta)=1, what would that be called?

[charred flint]

double angle identity

[sage jacinth]

simplification using the double angle identity

yea

[gloomy timber]

thanks

@charred flint thanks for all your help

@sage jacinth also thanks as well

[sage jacinth]

anytime

[alpine sable]

can someone help with this

im super confused

[charred flint]

@alpine sable there's a lot going on, but you should notice that 3n^2 being close to 2(n+1)^2 is a really specific condition

so just try to write the equation for 3n^2, something, 2(n+1)^2 being consecutive integers

[alpine sable]

so 3n^2 + 2 = 2(n+1)^2?

[charred flint]

yea

[alpine sable]

hm okay now what would would I do?

[charred flint]

expand (n+1)^2

[alpine sable]

should i solve for n

?

or just expand (n+1)^2

@charred flint

[charred flint]

solve for n yea

when you expand that it'll be really easy

[alpine sable]

n = 4, 0

@charred flint

[charred flint]

yup

so just plug in to find m

[alpine sable]

so I do both 3(4)^2 + 1 = m^2 and 3(0)^2 + 1 = m^2

so i should have 4 values of m then?

@charred flint

[charred flint]

close

the negative ones actually won't work

since 3n^2 is 3 times n^2

and n^2 is positive

woops nvm

4 solutions yea

[alpine sable]

okok thank you

[orchid valley]

The movie titles that Emir would like to watch are given below.

Tuesday        | Film D -  Film E
Wednesday | Film F - Film G - Film H
Thursday      | Film I - Film J
Friday            | Film K - Film L - Film M```

The movies all start at 8.00PM. Emir will only watch 1 movie a day, so how many different choices can Emir make?

How can i solve this? I have no idea.

[ionic jewel]

lets try two days

if we only care about monday and tuesday how many different choices?

[orchid valley]

oops i have wrote Friday's films wrong

i fixed

[ionic jewel]

no matter, how many for only monday and tuesday? @orchid valley

or are you not here anymore?

[orchid valley]

i dont know how to do, im on 8th grade

[ionic jewel]

okay

how many choices does he have for only monday?

[orchid valley]

3

[ionic jewel]

okay

how many choices for only tuesday?

[orchid valley]

2

[ionic jewel]

so if he has 3 choices for monday, and 2 choices for tuesday, how many total choices does he have

consider listing out all the posibilities before guessing

[orchid valley]

a d
a e
b d
b e
c d
c e
true?

[ionic jewel]

yea thats perfect

so how many is that?

[orchid valley]

6

[ionic jewel]

how about monday, tuesday, and wednesday now

dont list them out

think about how you could extrapolate

hmm

if you are lost think about how you went from 3 choices on monday and 2 choices on tuesday, to 6 choices combined

[orchid valley]

3^3.2^2
27.4
108

is it 108?

[ionic jewel]

yes

good job!

[orchid valley]

thank you very much

[hexed girder]

Is this channel free?

[charred flint]

yea

[hexed girder]

Can someone help me how to prove that set U = { (x.y) : -x<y<x} is open U is subset of R^2

[charred flint]

um well you want a radius formula so that the circle centered at each point in U is still in U

usually you just take the halfway point between the point and the boundary

[hexed girder]

Yeah but I don't know how to choose radius

[charred flint]

do you see what the slope of the boundary is?

[hexed girder]

yeah but you can find an y in that boundary and x<y then that is not element of U

[charred flint]

I'm looking at the lines between the interior points and the boundary

the slopes of U are at 45 degree angles right?

so like if you expand the circle at a point in U, it'll first hit the boundary at a 45 degree angle

as in if you take the radius smaller than that distance, the whole circle will stay inside

like the worst case scenario

[hexed girder]

Not sure that I got it, but thanks for help mate 😩

Okay got it now 😄

[glass lichen]

differentiate again

$\dv[2]{y}{x}=\dv{x}\dv{y}{x}$

[ocean seal]

moshill1

[glass lichen]

also read the rules on helper ping

[sage jacinth]

you have to find the derivative twice

so if dy/dx = (3-y)cosx i think you just have to find the derivative of that

since they gave you dy/dx

[glass lichen]

take another implicit derivative

$\dv{x}\dv{y}{x}=\dv{x}[(3-y)\cos{(x)}]$

[ocean seal]

moshill1

[sage jacinth]

just wondering why isn't it written as d^2y/d^2x^2

[mellow kelp]

Is this channel busy rn

[torpid estuary]

dont ask in multiple channels

its fine

also ping 15 mins after posting

[jagged imp]

differentiate both sides.

since the derivative of dy/dx is d^2y/dx^2

what's your answer then?

eren this channel is occupied

take your drip somewhere else

looks right to me, you can sub the value of dy/dx in if you want

since you already have it

d/dx(y)=dy/dx

[fleet steeple]

Hey, can I post my question if you guys are done?

It doesnt crash phones probably

[tame shell]

used my desktop to verify the crashing, pulled out my phone to ban

[tall wing]

makes sens

[tame shell]

if you wanna test out the gif you can find it in #〖logs-deleted〗 @tall wing

[tall wing]

lol

i have no plans on sending it anywhere else

[fleet steeple]

help

how do they distribute the two sides to get the answer they got

[night geyser]

what step of the solution dont you understand?

[fleet steeple]

the first one lOL

yuh

i dont understand

[night geyser]

its difference of squares

$a^2 - b^2 = (a+b)(a-b)$

[ocean seal]

Namington

[fleet steeple]

OH YEAHHHH

[night geyser]

apply that to a = (n+3^2019), b = (n-3^2019)

[fleet steeple]

wait

i dont think that work

because its subtracting it

not multiplying

subtraction is just -1 multiplied by it

so it might work

wait

i dont think its gonna work

[night geyser]

erm

i dont follow

[fleet steeple]

can you show what it will result as

because its not (a+b)(a-b)

its (a+b)^2-(a+b)^2

technicaly we could square root

everything

[night geyser]

pink is a

green is b

on the left hand side, we have a^2 - b^2

on the right hand side, we have (a+b)(a-b)

but instead of "a" and "b" we have "n+3^2019" and "n-3^2019"

you can still do the same manipulations, though

since a and b are variables

they can stand for anything

[fleet steeple]

yeah

ok i see it now

[night geyser]

including n+3^2019 and n-3^2019

[fleet steeple]

howd they get 2n then

cause if its multiplcaiton

the product would be 2n*0n

[alpine sable]

Hey guys I need some help

I need a simple definition for objective sample, proportions sample, convenience sample, and biased sample.

Apparently when I email my teacher she just said we reviewed it in class and doesn’t actually help me

[fleet steeple]

nvm lol

im just stupid

[raw inlet]

can someone help me derive this, I know the ans but I'm a bit confused on the process

[loud nexus]

anyone know if exist a software for arithmetic operation?

[midnight cloud]

how would this work

what rules?

did i interupt something

okay

[mellow kelp]

I did

Is this busy

That questions been unanswered for like 3 hours

they’re not even back

[alpine sable]

update, I barely understand the reasons but I’ve equated the part in A to be 2.5 < x < 5.5

[thorn kindle]

@alpine sable triangle inequality

a+b > c

no thank you.

[tall wing]

oh did someone kick or sth

i was just gonna say not to do that

okay

[fading citrus]

bad faith, yes

[tall wing]

ye its cool

i tend to be more soft, i should really not think so hard when dealing with this

[tame shell]

i decide depending on the type of server, it was one of those "get rewards based on how much you spam this across every server you're in"

so i just banned them

[alpine sable]

Can someone help me on how to simply define who Blitzkreig is dm me pls i have no clue

[tame shell]

what

that has nothing to do with math, just google it

[alpine sable]

Yo can I ask a question?

When drawing a graph do I got outside the points?

[lunar oar]

i personally draw the line a lil bit past my last point, but my last point is always the last one i was given to graph you know what i mean?

[alpine sable]

So I can go outside a little but not a lot?

[magic patio]

Does anyone know how to do this

[tight locust]

dude you've posted this same question 5 times please stop

[lunar oar]

@alpine sable like this sort of

[magic patio]

who

[tight locust]

you

[lunar oar]

@magic patio ahh sorry i dont know this i havent learned about it

[magic patio]

yes maybe because I still have trouble with it and haven't got help 😫

[alpine sable]

@lunar oar ty

[lunar oar]

@tight locust hey bro they're just trying to get someone to help them, no need to be rude

@alpine sable nw hope i was of help 🙂

[mild heath]

Mathematic

[alpine sable]

im focusing on b since its clusterfucked

but i know (((nothing))) about reasons

[thorn kindle]

i literally just gave you the answer for a

it's called the triangle inequality

[sage jacinth]

yea any two sides of a triangle have to be greater than the third side otherwise a triangle wouldnt be formed

so knowing that you have a triangle you can solve for the range of the final side

[alpine sable]

How do I solve for x in the problem. 2x/5=12?

multiply by 5 on both sides and see what happens

[eager pebble]

How would I solve this without a calc

part a that is

[ionic jewel]

looks like trig sub

sqrt(1+9x^2) is a great hypotenuse for side lengths 1 and 3x

you can then do sin(theta) = your integral, integrate to get -cos(x) = -2x/sqrt(1+9x^2), then i guess it goes from x=0 to infinity so do the limit thingie for that

[eager pebble]

isn't that an arctan integral?

inside a square root

[ionic jewel]

hm

yea

1/3x * arctan(1/3x)

[rare finch]

How do I perform analysis on a dataset to find these

I'm thinking of using minitab but idk

I've been told to ping <@&286206848099549185> I hope that was not a prank

[limpid spade]

It was

[thorn kindle]

Yeah lmao

That's an old April Fool

[novel spruce]

the helpers volunteered to get spammed though

[alpine sable]

bro what is this?

[thorn kindle]

Whats the question

Lmao

[novel spruce]

what is A?

I doubt I can help since I don't know that much statistics :L

[thorn kindle]

Up 6

[novel spruce]

bro

just think, every value you're adding six

what does that do to the graph @viscid tangle

[thorn kindle]

Down 1

[thorn kindle]

Vertical reflection

[limpid spade]

Amd stop giving answers right away

[mystic sinew]

I don't get it why doesn't it converge

the thing you're adding is getting smaller and smaller

[rare finch]

data analysis

[limpid spade]

Beyond no one's gonna give answer right away

Its not allowed

[novel spruce]

you give me a number X, I can find a number N such that if you add N terms the series grows bigger then X

[limpid spade]

You're in the wrong server

[novel spruce]

thats what they're showing in the bottom @mystic sinew

[mystic sinew]

I don't get it at all I looked at the explanation

[novel spruce]

they diden't fill out the series enough to see it on the bottom

[mystic sinew]

I forgot how you're supposed to graph series like that

just summations right?

[novel spruce]

@mystic sinew hang on lemme find the khan video on this

https://youtu.be/4yyLfrsSXQQ

$1 + \frac 12 + \frac 14 + \frac 14 + \frac 18 + \frac 18 + \frac 18 + \frac 18 + \dots \le 1 + \frac 12 + \frac 13 + \frac 14 + \dots$

[ocean seal]

uli

[novel spruce]

so if you rearrange the smaller guy it becomes $1 + \frac 12 + \frac 12 + \frac 12 + \dots$

[ocean seal]

uli

[novel spruce]

its kinda mind bending for me too @mystic sinew :3

[mystic sinew]

will think about it later I don't have the mental capacity rn

[thorn kindle]

The harmonic series is actually the boundary

Anything even slightly faster than harmonic will converge

[mystic sinew]

look up transformations or watch the khanacademy thing on it

[upbeat gorge]

do you know how to write points

[burnt dock]

do you mean marking places on the graph

[red whale]

how do i fix this

im confused

[novel spruce]

you gotta move along the x axis

so you gotta shift x

[red whale]

horizontal yea i tried

maybe it was the wrong value

inside parenthesis?

[upbeat gorge]

DEF is marked on the graph, so first you have to read the grid and write what D, E, F are

[red whale]

im confused

i cant find the right value

closest i could get

[burnt dock]

D is 0, F is 2, and E is 2 right

[red whale]

slightly off tho 😦

[upbeat gorge]

(x,y)

[burnt dock]

so just 2 and 2

[upbeat gorge]

no

first off, do you know how to express a point in the form (x,y)?

[red whale]

also is a cycle and a period the same thing

for sin and cos graphs

[novel spruce]

from the graph it looks like they want $f(0) = 0$

[ocean seal]

uli

[burnt dock]

no

[novel spruce]

so you want $3\sin(2(0) + c) + 3 = 0$

[ocean seal]

uli

[upbeat gorge]

wait how are you learning about coordinate geometry before knowing the basics of the cartesian plane

[burnt dock]

what do you mean express x and y

you mean how to put it in the parenthesis

[upbeat gorge]

like (0,0), (2,1), etc

[burnt dock]

oh yes i know that

[upbeat gorge]

ah.

so yeah you need to express D, E, and F in that format

[burnt dock]

but how would i put 3

[red whale]

wait

sorry uli im confused

my c is off

yet idk why

wait

nvm

this works

thats so weird wouldnt u think for a question c wouldnt be some arbitrary stupid non whole number and a real full number?

yet no its just 4.7

[upbeat gorge]

$D=(x_1,y_1), E=(x_2,y_2), F=(x_3,y_3)$

[ocean seal]

CST

[red whale]

correct right?

[novel spruce]

no

[red whale]

what

[novel spruce]

you want $3\sin(c) + 3 = 0$

[ocean seal]

uli

[novel spruce]

waitt no

[ocean seal]

uli
Compile Error! Click the reaction for more information.

[red whale]

3sinc(x)+3 is not it

correct right?

[burnt dock]

do i put x and y as 0 for D

[red whale]

im pr sure

some stupid arbitrary number 4.7

[ocean seal]

uli

[novel spruce]

it isn't arbitrary

wait no

[red whale]

what

[novel spruce]

i'm so tired asfasdf

sorry

[red whale]

is that not right what i put

[upbeat gorge]

yes

[red whale]

no its totally fine thank you for helping

[novel spruce]

no no no

[red whale]

what

what i do

[novel spruce]

$4.7$ is just close to $\frac{3\pi}{2}$

[ocean seal]

uli

[burnt dock]

and 2,2 for F and E?

[red whale]

OH

[novel spruce]

that's the real value you want @red whale

lemme show you a picture

[red whale]

YIKES THANK U MY TEACHER WOULDVE KNOWN I WOULDVE JUST PUT IN NUMBERS BETWEEN 4 and 5 UNTIL I WAS RIGHT

THANK U

WHY THO

[upbeat gorge]

no

D is (0,0), yes

but E isn't (2,2), nor is F

[burnt dock]

oh is it 0,2 and 2,0

[novel spruce]

@red whale

[upbeat gorge]

yes, for F and E, respectively

[novel spruce]

sine tells you your $y$ coordinate around a unit circle (circle with radius one) after walking some amount around the circle

[ocean seal]

uli

[red whale]

yes sin x cos y

[novel spruce]

the whole circles circumfrence is $2\pi$ so to get to the $-1$ spot is $\pi + \frac{\pi}{2} = \frac{3}{2}\pi$

[ocean seal]

uli

[red whale]

sin(3pi/2) would j be 0

[novel spruce]

you could also let $c = - \frac{\pi}{2}$ that would also work

[ocean seal]

uli

[novel spruce]

yup

because for $3\sin(c) + 3 = 0$ you need $\sin(c) = -1$

[burnt dock]

and so does 2 go here

[ocean seal]

uli

[red whale]

oh yes coterminal

tru

thank u af < 3 life saver

[upbeat gorge]

yes, since 2 is the given scale factor

[burnt dock]

and is this what it should be after multiplying

[upbeat gorge]

yep

and that's that

[burnt dock]

thanks so much for helping me

you explain it way better than my teachers

[upbeat gorge]

tbf you're lucky that the center of dilation is at (0,0)

anyway np

[red whale]

ok what

now im confused

[burnt dock]

is the answer 4

[red whale]

what type of dilation translation whatever the fuck

anyone understand that one?

[upper ember]

ya, i think so

[burnt dock]

my brain hurts can someone help

[burnt dock]

also thanks

[limpid spade]

What's the length of BA

And B'A'

Each square has length 1

[upper ember]

B'A' is 2sqrt2

and BA is 4sqrt2

ig

[bitter fox]

Find the velocity vector of an airplane traveling 480 mph at a bearing of N 55deg W.

Can anyone help me with this 😄

[burnt dock]

lol when are u gonna need to know that question

[upper ember]

the answer is 2/5

[burnt dock]

ty

[gleaming granite]

I might be misreading this, but 480 m/h is a speed value the direction is N 55 deg W making it a vector...so aren't you already given the vector value of velocity?

[dark canopy]

I have no idea what I'm doing here

[bitter fox]

Then what would be the velocity vector

[jagged imp]

480 m/h in the direction N55W

[gleaming granite]

480 mph in the N 55 deg W direction

[jagged imp]

but you want it in compoenent form

[bitter fox]

Mhm

[jagged imp]

as you told me earlier :)

[bitter fox]

Yup but in component form!

[jagged imp]

use trig

[craggy trellis]

guys im stuck, how do i go from here?

i'm not asking for the answer, i just wanna know how to move forward

[errant bear]

im not smart enough sorry bro

[craggy trellis]

it's okay king 🤧 you're smart regardless

[alpine sable]

6 and 7

[alpine sable]

Yes, you aren't.

[burnt dock]

does anyone know how to do this

[errant bear]

how old is everyone here

[burnt dock]

how old are you

[gleaming granite]

https://tenor.com/view/old-man-guy-senior-walker-gif-7660497

[errant bear]

im 13 bruh i came in here so i dont have people bossing me around i need a free tutor lol

[craggy trellis]

wait how did you get those answers though?

[errant bear]

im failing math and i need help

[wild shard]

Hello is anyone here good with shader code?

[alpine sable]

solving the quadratic equation

[craggy trellis]

yeah but how do i go from there? like what's the next step in that problem? i'd super appreciate it if you drop some knowledge on me 😭

[alpine sable]

Are you acquainted with the quadratic formula?

[upper ember]

scale factor is 1/4, and relation of area is
b'h'=16bh
where b*h is the area

[alpine sable]

This is pretty elementary stuff.

[craggy trellis]

yeah im in intermediate algebra :/

but no im not acquainted with it

[burnt dock]

lol i guess and then turned it in already

ill unsubmit

[craggy trellis]

it's an extra credit problem that im trying to solve

[upper ember]

solve this quadratic, using the quadratic formula, which is
$\frac{-b\pm\sqrt{b^2-4*a *c}}{2a}$

[errant bear]

can someone help me im failing math and i got to finish this by 5 in the morning someone please help im not to smart

[ocean seal]

Samsyet Marvolo Riddle

[burnt dock]

ok did it just in time

[alpine sable]

Doing that you should get $$x_1=6$$ and $$x_2=-\frac{7}{2}$$

[alpine sable]

why would you wanna do that?

[burnt dock]

there were 7 seconds before it was due and i was fast enough

[heavy flicker]

Who can help

[upper ember]

here, a is the coefficient of x^2, and b is the coefficient of x and is the constant

[ocean seal]

Spurious

[craggy trellis]

ooh okie dok. ill go from there. thanks spurious and samsyet. i super appreciate it

[heavy flicker]

Help with it pls

[alpine sable]

Which one?

[heavy flicker]

With 1-3 if you can

if not much time, only 1

[wild shard]

Hello, is anyone here good with shader code
Im trying to make a rotating torus
but am failing miserably, and cant seem to figure out why
https://www.shadertoy.com/view/fsSGWy
it seems to be a problem about rotating the 2d circle about the y axis

I'd thought id ask here since its more of a math problem if anything...

[alpine sable]

Does anyone know the domain and range of this problem? I looked on homework help, but still no luck for this.

[alpine sable]

So for number 1 you get $$\frac{x}{2}+\frac{\pi }{3}=\frac{4\pi }{3}+2\pi n ,: \frac{x}{2}+\frac{\pi }{3}=\frac{5\pi }{3}+2\pi n$$
$$x=4\pi n+2\pi ,:x=4\pi n+\frac{8\pi }{3}$$

[ocean seal]

Spurious

[heavy flicker]

Ok

[ocean seal]

mukul

[spring perch]

Do you think you could do something similar for the range @alpine sable?

[alpine sable]

yes thank you so much

The function f(x) is an absolute value function.

  What is the equation for the parent of f(x)?
  Make a complete graph of the parent of f(x).
  The function f(x) is created by taking its parent graph, shifting it to the right 3 units, down 5 units, vertically stretching it by a factor of 2 and       turning it upside down. What is the equation of f(x)?
  Make a complete graph of f(x).
  What are the domain and range of f(x)?

This is what I got, I am pretty sure I can figure out all the problems, but how do you find an equation for the parent of f(x) when all I get is the top line

[gleaming granite]

The parent function is the absolute value function with 0 transformations

Absolute value function: $y = a \abs{x-h} + k$

[alpine sable]

wait so f(x) = 0 is what that means?

[ocean seal]

keto11

[gleaming granite]

no it means that there are no transformations being done to the absolute value graph

the graph isn't being shifted or streched at all

[alpine sable]

oh ok this was another that was giving me some troubles, thanks for the help explaining it.

[gleaming granite]

What did you get for the answer for the parent function?

[alpine sable]

the parent function would be f(x) y = a|x - h| + k. because for this question I believe they are asking for the equation.

[gleaming granite]

not exactly

the parent function is when there are no shifts in the x and y direction and streching of the function

@alpine sable could you give me the parent equation of a parabola?

a quadratic equation

[alpine sable]

I have that in my notes, y = ax2 + bx + c

[gleaming granite]

that's the standard form

[ocean seal]

keto11

keto11

[gleaming granite]

@alpine sable do you see a pattern between what i posted

[alpine sable]

yes I believe so, so the parent function would be y = x^2, if I am not mistaken, but does this go for any parent function?

[gleaming granite]

that's the parent function for a parabola

[ocean seal]

keto11

[gleaming granite]

that's what you can use for any parent function

[ocean seal]

keto11

[alpine sable]

ok so this works for all parent functions, and with this in mind, the parent function for f(x) would be y = x because y = 1|x - 0| + 0

[gleaming granite]

it wouldn't be y = x though

you forgot the absolute value signs

y = |x|

[alpine sable]

so parent functions have to have absolute value signs?

[gleaming granite]

remember that you're finding the parent function for an absolute value function, so you have to keep the absolute value signs

in fact you had absolute value signs before

i don't know why you just got rid of them

[alpine sable]

oh my bad I should have looked back at the problem.

[gleaming granite]

np

so howd the graph for this look like?

y = |x| ?

@alpine sable

[alpine sable]

a v shape? going at a direct rate of 1 diagonally.

[gleaming granite]

yep

[alpine sable]

wow I have to stop surprising myself, I should believe I am right once in a while. lol

[gleaming granite]

LMAO

yes sirrr

actually

being confident in your process is really important down the road

sometimes you will have to solve problems that haven't been solved before and you'll have to have confidence in your process before you move onto the next step

[alpine sable]

yea I know this is all just very new to me I know graphs a lot better than equations though, you are very right.

[upbeat basin]

Does anyone know what type of equation that graph would be

[small umbra]

help pls

[alpine sable]

19.2 m

help pls

[ionic jewel]

what is Q1 Q2 and Q3? @alpine sable

oh
