[alpine sable]

i ACTUALLY UNDERSTAND

this is exciting

We start with 116.14 friends

After one year it's 113.2 etc

yea

Alright that's great

There are a lot of infos in your problem but if you take your time to sum it up it becomes clear

last thing is the r^2=.58 im still kinda confused

Well you see

The statistician did his graph

point by point

And he has something that's not a line right?

The points are not perfectly aligned

That would be too lucky, in reality it doesn't happen

But he needs a line so what does he do?

He draw a line passing through the maximum number of points

r²=0.58 is about how much points the line passes through

The line passes through 58% of the points

The line described by friends=(-2.94)*age+116.14 (or f=-2.94x+116.14)

For example, here the point represents reality (the data he collected) and the line is an approximation of what's going on, r² is about whether the approximation/line is close to reality

If you have r²=1 the points were perfectly aligned

if r²=0 the points are everywhere and we can't really draw a good line

yea

im actually understanding it

you're an amazing teacher dude

Thx

[ornate condor]

help w rational root theorem

[ornate condor]

so if weve some

a3x^3+a2x^2+a1x+a0=0

wot nao

[keen plinth]

welcome

[ornate condor]

[keen plinth]

you check the factors of a0 and the factors of a3

and the rational roots will all be of the form +-(factors of a0)/(factors of a3)

[ornate condor]

wait

first

so a0,a1,a2,a3

has to b ints

yes?

[keen plinth]

lol ofc

[ornate condor]

hm

[keen plinth]

otherwise factors of a0 doesnt really make sense

[ornate condor]

n factors means pos n neg?

[keen plinth]

no i wrote a +- so

[ornate condor]

o

[keen plinth]

you only need positive factors

but like

if you include both +-

then you get the +- anyway

[ornate condor]

hm

then so

this always works?

or nani

[keen plinth]

well

[ornate condor]

it always works given a rational root exists?

[keen plinth]

all RRT says is all rational roots must be of the form +-(factors of a0)/(factors of a3)

[ornate condor]

so a quad with

1,1,1

[keen plinth]

and nothing about whether any of them are actually roots

[ornate condor]

fails

[keen plinth]

well you get +-1/1

and then thats it

[ornate condor]

wait all?

[keen plinth]

and none of those are roots

and thats it

well yes

RRT says if you are a rational root, you are of the form +-(factors of a0)/(factors of a3)

[ornate condor]

ok i thought it was one

so rrt also works

on some eq

if we can * some k such tht they r all ints

btw why must the a1,a2 b ints

[keen plinth]

because number theory

[ornate condor]

confusion

o well

thanks

Imagine using Fortnite for your Physics test

[alpine sable]

😆 image Fortnite is the Topic of your final Math Exam

[rough sonnet]

I remember we once got a Physics test on projectile motion. 2 questions. One was The Hunger Games themed and the other one had Selena Gomez crashing her car.

I am not kidding.

[alpine sable]

Selena Gomez

[rough sonnet]

Granted this was 9th grade

[alpine sable]

crashing her car? oh my gosh

[rough sonnet]

Yeah like driving her car off a bridge into a fairly large drop

Fortunately the only one that died was the car

She was just fine.

Until you did the problem and realized she decided to commit insurance fraud.

I will not elaborate further.

[alpine sable]

so it was like a braking distance question?

[rough sonnet]

Yes, actually

[alpine sable]

i first read "unfortunately" the only one who died... so like you wanted Selena Gomez to ... xd

[rough sonnet]

The question was to find out whether she had actually used her brakes or not.

[alpine sable]

nice to hear Selena is fine 🙂

[rough sonnet]

No she's in jail for insurance fraud

[polar bluff]

Hi

[polar bluff]

I’m a bit lost

With this

Oops <AF= y, so would that be the overall 360?

So 5x-15=360,x=75?

[ornate condor]

whered u get 15

also im p sure its

10x + something = 360

not 5x

[keen plinth]

half the revolution bruh

[ornate condor]

wot

its 5x.. = 180

so i just doubled

[keen plinth]

yeah that's the problem

[ornate condor]

??

[keen plinth]

it should be = 180

[ornate condor]

well

ok

i thought u were gonna say the angles are not preserved when doubled

[polar bluff]

I lied, y=3x+6 so I doubled it and CLT w the rest and added all up to 360

[ornate condor]

[keen plinth]

[polar bluff]

I solved it

[agile shadow]

Are they not all opposite angles? 2 of each given angle add to 360?

[ornate condor]

ok

good job

[polar bluff]

No

Well

[ornate condor]

how did u even aplly clt lol

[polar bluff]

FB = AF

Ok so

[keen plinth]

CLT?

bru

[polar bluff]

3x+6 x 2 = 6x+12, then the others

why did you multiply by 6.8 twice?

wdym?

[umbral zinc]

shouldn't 4 be multiplied by 6.2?

[glad trout]

Help me please

[buoyant storm]

Make it (x+b/2)^2+c-b^2/4

I guess

[glad trout]

When they said consider three different cases what they mean by that?

[rose relic]

i believe it's related to the value of the discriminant

do you have 2 real roots, 1 repeated real rool or 2 complex conjugate roots

not sure

[shell widget]

Maybe just consider cases b=0, c is not 0, c=0, b is not 0, both not zero

[glad trout]

Wait

I got hint earlier

For three cases and it says

[shell widget]

2 is just power rule, for 1 and 3 u need trig subs

[glad trout]

How do I apply it to my question

Let’s just say

I completed the square

How do I proceed?

<@&286206848099549185>

[shell widget]

You can write it as (x+(b/2))^2 + sqrt[(c-(b^2)/4)]^2, so you just have something of the form X^2 + A^2

assuming c-(b^2/4) is positive

[rigid smelt]

I also suggest you to substitute something for c-b^2/4 just for the sake of making it cleaner so you dont accidentally leave a minus sign somewhere and trip yourself

[glad trout]

Okay if u see the hint earlier, does that mean c-(b^2/4) can be considered as positive negative and 0?

[shell widget]

Yes

[glad trout]

Right

Okay think I get the idea

[glad trout]

Why did square root c-b^2/4?

Oh wait nvm

[glad trout]

Wait what else to do from there

Assuming c-b^2/4 is positive I just take tan as a substitution

[shell widget]

Yeah

[glad trout]

So x+b/2 = tan theta?

[shell widget]

Uh

First let x+(b/2) = X, c-b^2/4 = A^2

You get 1/(X^2 + A^2)

then use the substitution X=Atan(theta)

[glad trout]

And that will be 1/atantheta^2 + a^2

Could u verify if I have to integrate this and substitute back the theta and a?

@shell widget

[shell widget]

1/[A^2(tan^2 (theta) + 1)]

then use tan^2(theta) + 1 = sec^2 (theta)

and since ur now integration wrt theta, you need replace dx as well

[glad trout]

Why +1?

[shell widget]

factored out A^2

[glad trout]

Oh right

I see got it

Hold up

@shell widget

[tall topaz]

You forgot to multiply by the derivative of x

[glad trout]

Oh shit

Right

For x^2-a^2 we use sec right?

@tall topaz @shell widget

[shell widget]

Yes

[glad trout]

Ok I’m that case it will be like this right?

@shell widget sorry to keep tagging u

[alpine sable]

Can you please help me simplify this one and show me the process?

[shell widget]

@glad trout Yes

sec^2(theta) - 1 = tan^2 (theta)

[tall topaz]

I think it wants you to use partial fraction

Rather than trig sub

[wheat isle]

Hey could I get help with Question 5 please? I’m particularly stuck on F and C

[wheat isle]

I don’t know what Part F is asking with the question mark box

[alpine sable]

seems like a typo, ig treat it like a variable called '?'

[wheat isle]

So is it asking me to put any input?

[alpine sable]

yes, a variable can be thought of as an arbitrary input

[wheat isle]

So when is says f of x, do I put that in all of the x’s like for example

It says f(-x)

x (-x)/x(-x)^2 + 1?

[alpine sable]

yes, everywhere you see an x, put -x instead

[harsh ivy]

How did it get factored?

[harsh ivy]

I need to revise on that

But do i need it to take a common factor?

.

[tall topaz]

I thought you already got this

[harsh ivy]

i did but there is a part i don’t understand

[tall topaz]

Which

[harsh ivy]

how did you get this

[tall topaz]

$(\theta +
\cot {\theta}) \times (-\csc{\theta}\cot{\theta})$

[ocean seal]

Pure

[harsh ivy]

can you explain it to me pls

How do i multiply cot

cot * cot

[tall topaz]

$=(\csc{\theta}\cot{\theta})\times (\theta +
\cot {\theta})$

[tall topaz]

That’s just cot^2

[harsh ivy]

oh i see

and cot * csc?

[tall topaz]

I mean csc = 1/sin and cot=cos/sin

So csc*cot = cos/sin^2

[harsh ivy]

oh

[tall topaz]

But that’s not relevant here

[harsh ivy]

Then how do i multiply it here

[ocean seal]

Pure

[tall topaz]

This is what we have

Multiplication is commutative and associative

[harsh ivy]

This is the same thing just without the negative sign

[tall topaz]

Ah yeah I forgot the negative sign

$=-(\csc{\theta}\cot{\theta})\times (\theta +
\cot {\theta})$

[ocean seal]

Pure

[tall topaz]

We have this

[harsh ivy]

yes

[tall topaz]

$=-(\csc{\theta}) \times (\cot{\theta})\times (\theta +
\cot {\theta})$

[ocean seal]

Pure

[tall topaz]

$=-(\csc{\theta}) \times (\cot{\theta}(\theta +
\cot {\theta}))$

[ocean seal]

Pure

[harsh ivy]

okay so we just put it inside a bracket cuz its already all multiplied

[tall topaz]

$=-(\csc{\theta}) \times (\theta \cot{\theta} +
\cot ^2{\theta})$

[ocean seal]

Pure

[harsh ivy]

okay i got this now the last part is csc * cot

we shouldnt do ot and just take common factor right?

[tall topaz]

Yes

[harsh ivy]

ah i see

okok thank you so much

im rlly suffering in math

[tall topaz]

[harsh ivy]

🥲

Cya and thanks you so much for helping me i can’t find anything thing to explain to me

couldnt*

I got the first step, but idk what to do afterwards. im trying to prove bec = dea

[lone heart]

@glacial trail Has your question been resolved?

[gray isle]

consider the definition of bisection and what step 1 tells you about certain lengths,

applying that thoroughly will lead to the required congruence proof

[glacial trail]

wdym

bisecting is just 2 lines meeting at the middle right

[gray isle]

so what does that tell you about the lengths of certain segments

[digital walrus]

It asks to simplify in terms of the second expression

This is what I’ve got so far

Am I on the right path or close?

[toxic badge]

is that not as simple as it gets

whats the sin x doing there

[digital walrus]

nah, I gave up like halfway cause my brain is burnt out rn

the sinx is what it wants the simplified answer in terms of

the answer is 1/sinx, I'm just not sure how to get there, or if the work I currently have is on the right path

[digital walrus]

yeah, I tried that app earlier, it seems to kinda give up with most trig identities lol

[toxic badge]

works fine

[digital walrus]

oh well damn

that's weird

how do i state the domain and range of each relation and how do i determine whether each relation is a function. if it is a function, determine if it is onto, both, or neither.

[digital walrus]

Domain is an interval from the lowest X-value to the highest, Range is that for the Y-values

A relation is not a function if any x-value has 2 different y-values

for example, if you had the set { (0, 1), (0,2), (1,2 }, this would not be a function because 0 is paired with 2 different Y-values (1 and 2)

[alpine sable]

ahh

im not sure what that means

can i get more like a

idk

EASIER EXPLANATION i dont know english that wlel

[alpine sable]

bu why

but*

[digital walrus]

A function basically takes a number and spits out a new one. If you have the function y=2x, and you give it the number 2, it's the same as saying 2x2, so it'd be 4. A function can't give more than 1 answer for any given number.

[alpine sable]

OHH

so 0 isn’t compatible

[digital walrus]

You can also think of this with the "vertical line test". If you graphed the points that a problem gives you, would you be able to draw a single vertical line and touch more than one of them? If so, it's not a function, and if not, then it is a function.

[alpine sable]

What does onto mean

in this case first question

would not be a function

because of the

0.5

if im correct

or well there’s a 0

[digital walrus]

correct, but because of the 0.4, not the 0.5

[alpine sable]

i just don’t know how to determine wether it’s a onto or both or neither

[alpine sable]

oh why

oh yeah

0.4, and 0?

[digital walrus]

0.4 appears more than once, and because it's the first number in a pair (making it the x-coordinate), it violates the rule that an x-value can't have more than 1 y-value

[alpine sable]

if it shows more than once it's not a function

and because of the 0?

[digital walrus]

If 1 number in the X spot of (X,Y) appears more than once, it's not a function

[alpine sable]

oHH

[digital walrus]

The 0 doesn't matter here

[alpine sable]

i understand it now tysm

[alpine sable]

ohh

so its only if it

repeats

its not a function

[digital walrus]

yes, if an x-value repeats, it's not a function

[alpine sable]

does the same go with y-value?

[digital walrus]

no, only x

[alpine sable]

ohh

how do i know which one is the x and y value in the first problem

is like

the first two

sets

y values

and the last 2

x?

[digital walrus]

Notice how the problems gives you sets of numbers in parentheses? Those are called ordered pairs, The first number in any ordered pair is the x-value, and the 2nd is the y-value

[alpine sable]

OHH

I GET IT

so in this case

[digital walrus]

so for the first problem, you have the points (0.5 , 3) , (0.4, 2) , (3.1,1) , and (0.4, 0)

[alpine sable]

0.5 is x and 3 is y

[digital walrus]

yes!

[alpine sable]

0.4 is x and 2 y

3.1 is x and 1 y

0.4 is x and 0 is y

awesome

[digital walrus]

exactly!

[alpine sable]

now if it's a function how do i know it's onto both or neither

[digital walrus]

I honestly have no idea what “onto” means there

[alpine sable]

i don't either 😭

i tried searching it up

and it says

'If A and B are the two sets, if for every element of B, there is at least one or more element matching with set A'

but i still dont know

im not sure if the x is a and b is y

do u know what would mean as for both or neither?

[digital walrus]

I’m assuming both and neither refer to relation and function

but still not sure

[alpine sable]

ohh

okii

what about this one

[digital walrus]

A continuous function can be theoretically drawn forever without lifting your pencil

both of those functions are continuous

I won’t explain exactly how to draw each of those graphs, but I’ll say that y=x^2-1 will look almost like the letter U, and y=3x+2 will be a diagonal line going up and to the right

For problems 7 and 8, simply replace the “x” in the given functions, with the the value in the parenthese

So for 7, you’ll turn -2x+4 into -2(12)+4 and solve it

[alpine sable]

ohh

[digital walrus]

For 8 you’ll replace “x” with “7c” and expand it, since it can’t be fully solved unless they tell you what c equals

[alpine sable]

where did the 12 come from

[digital walrus]

f(12)

[alpine sable]

OH

ooh i get it now for that one

i understand 7 and 8 but for 5 and 6 how do i graph

[digital walrus]

Do you know what the graphs X^2 and X look like?

[alpine sable]

not sure

if im being honest i don't really know how to graph 😭

[digital walrus]

A graph is essentially a visual representation of the all the possible solutions of a function

This is the graph of y=x

This is the graph of y=2x

[alpine sable]

ooo

how do i know if its a function

also i suppose its continous because its a straight line right?

[digital walrus]

A function is continuous if it has no end, and discrete if it only shows specific values

y=x is continuous because you can put any number for x and get an answer back

[digital walrus]

The vertical line test, if you draw a vertical line thru a graph and it hits more than once, it’s not a function

[alpine sable]

vertical as in straight line?

also what does hitting more than once mean

[digital walrus]

I is a vertical line, _ is a horizontal line

[alpine sable]

OHH

understood!!

so in that case for exp y = x^2 - 1 which it's shaped as a u it's not a function and its discrete

[digital walrus]

no

it’s shaped like a U, but it can be drawn forever in either direction, and it’s impossible to hit it more than once with a vertical line

[alpine sable]

OHH

SO IT WOULD BE

continuos

continuos

[digital walrus]

(I’m still currently making a visual example for what “hitting it more than once” means)

[alpine sable]

continous*

[alpine sable]

ahh okay tysm!!

[digital walrus]

This would be a function, because it’s impossible to draw a vertical line that crosses it more than once

This would not be a function, because it can be crossed more than once with 1 vertical line

[alpine sable]

OOHH

Second one is continuos and first one discrete right?

[digital walrus]

Although y=x^2 can get steep, it’s also impossible to cross more than once with a single vertical line

[alpine sable]

OHH

[digital walrus]

Neither of them are discrete

[alpine sable]

wait so what type of graph is discrete

[digital walrus]

A discrete function’s graph would look more like a set of dots, or a line split into multiple pieces, instead of one line that can be drawn forever

[alpine sable]

ohhh

[digital walrus]

Here’s a good example

[alpine sable]

OOO THATS REALLY HELPFUL

[digital walrus]

Oh, and to further explain the Domain and Range : intervals are basically a convenient way to show the maximum and minimum values of a function

[alpine sable]

Ahhh

[digital walrus]

So we’ll go back to this

[alpine sable]

Yes

[digital walrus]

What’s the smallest X-value here?

[alpine sable]

0.4

[digital walrus]

and what’s the largest?

[alpine sable]

3.1

[digital walrus]

Alright, so since an interval shows the largest and smallest values, those are the only numbers we’re concerned with.

Since those are X-values, we use them to write the domain

and that would be written as [0.4, 3.1]

[alpine sable]

ooohh

so that should be graphed as for

the x

[digital walrus]

Yes, those would be the horizontal position on a graph, but this problem doesn’t need to be graphed

Now, what are the smallest and largest Y-values?

[alpine sable]

3 is largest

and

smallest is 0

[digital walrus]

Yep, so what would the range be?

[alpine sable]

3,0

(3,0)

[digital walrus]

intervals are always written from smallest to largest

[alpine sable]

OH OK

0,3 in this case

[digital walrus]

Yep! And the type of bracket you use does actually matter

[0,3] means the interval includes 0 and 3, while (0,3) would not include 0 and 3

[alpine sable]

Ohh

[digital walrus]

So for these sets you’d be using [], because there’s nothing going on that would cause the numbers to be excluded

[alpine sable]

yes

I understand now!!

[lone heart]

[rustic cypress]

32x^{\frac{3}{2}}x-1=0

[rustic cypress]

how to simplify this further

[ornate condor]

well

x^3/2 x = x^5/2

[rustic cypress]

ok

32x^5/2 = 1

then what

[sour dove]

well, what else can you do here? You can't take a power to both sides yet because you have a constant on the LHS

[rustic cypress]

i can divide

by 32

x^5/2 = 1/32

ree

[sour dove]

well there ya go, so how do we get x by itself now?

[rustic cypress]

i can do tha root thing

[sour dove]

lol. Well what I would say is "raise both sides by 2/5" Make sense?

[rustic cypress]

ok

so then 5/2 *2/5 bcome 1 so

[sour dove]

good!

[rustic cypress]

x = (1/32)^2/5

but then i am conufsed

oh

wait

i am smart

i got it

1^2/5 = 1

and

32 ^ 2/5 becomes 4

[sour dove]

bingo! 🙂

[rustic cypress]

since 22222

my multiply since go away

OMG I AM SMARTY PANTYS EASy

[sour dove]

daaaang

you didn't even need my help

nicely done

https://tenor.com/view/weekend-party-champagne-gif-18280013

[rustic cypress]

thanks to you

but i also am smart

by also you

[sour dove]

darn tootin you are!

[rustic cypress]

tootin means ?

[sour dove]

it means "emphasis"

[rustic cypress]

ok

what does that mean

[sour dove]

but it's more slang than it is an actual word

[rustic cypress]

what slang means

sorry i dont know

lols

[sour dove]

no worries, that's how you find out!

[rustic cypress]

are you a pro at math

[sour dove]

slang is like "local tongue"

so like here in Texas

we don't say "hello"

[rustic cypress]

coool

[sour dove]

we say "howdy"

howdy is slang

[rustic cypress]

lololol

i heard someone say that in my school

can i quiz you

[sour dove]

yeah sure, sounds fun lol

[rustic cypress]

i ask my friends this trick math question

what is 1/0

if you get is correct that you didnt fall for it

[sour dove]

well it's undefined. We say that's an illegal operation in math

[rustic cypress]

darn it

lol

ok

another one

[sour dove]

can't stump me 😉

[rustic cypress]

1/2/3

i will get you

tell what is 1/2/3

[sour dove]

well we do PEMDAS from left to right. So it would be 1/6

[rustic cypress]

NO u got it wrong

it is january the 2nd and the 3rd year ad

gottem

EASY DUBZ

[sour dove]

lol daaaarn

[rustic cypress]

looool

[sour dove]

so like 01/02/0003 ? Like 3 years AD ? 😮

[rustic cypress]

YEA

lol

[sour dove]

lol well also! it depends on who you ask!

[rustic cypress]

you gotta be supar smart to get that

i think

let me guess what grade you are

and you guess what grade im in

my turn first

ok

so

[sour dove]

lol okay

[rustic cypress]

and then you say hot or cold

8th grade

[sour dove]

okay!

way cold

[rustic cypress]

6th grade

[sour dove]

even colder

[slender gull]

[rustic cypress]

ok then you are 10th grader

[sour dove]

getting warmer, but still pretty cold

[rustic cypress]

13th grade

[sour dove]

lol is that a freshman in college?

[rustic cypress]

that is colleg thought right

[sour dove]

if so then you're getting warmer

[rustic cypress]

ok 15th grade

[sour dove]

well we don't really have "grades" in college

[rustic cypress]

same thingg

[sour dove]

super warm!!!

if were doing grades lol

[rustic cypress]

HOW OLD ARE YOU

20 grade

[sour dove]

PFFFT

I think I was 10 when I was in 6th grade

[rustic cypress]

i just turned 13

woeowewo

[slender gull]

Lol.

[orchid chasm]

Can I have an explanation on why I have to rewrite this x^2 + 2x-x-2?

[long axle]

It’s so u can clearly see how the terms are about to be grouped

the x^2 + 2x becomes x(x+2)

And the -x-2 becomes -1(x+2)

Because it was grouped in that manner, we can combine the two of them to make

(x-1)(x+2)

See what happened?

hello, how can I get the area of this polygon?

[languid haven]

hmm

its half right?

[alpine sable]

I think

[languid haven]

k lemme see

[alpine sable]

look this one too wait just a moment

[languid haven]

its a hexaon

so

[alpine sable]

Yeah

[languid haven]

here have the formula

[alpine sable]

yes I know the formula but I dont know how to solve it

[languid haven]

oh

so

use the pythagorus theorum

so

[alpine sable]

ok ok

[languid haven]

the h = 24

b = 9

then youll find c to like

the middle of 18

[alpine sable]

yeah

[languid haven]

then you find the rest

[alpine sable]

I will do this one

[languid haven]

wait

[alpine sable]

A = N x S x A over 2

[languid haven]

thats more complex

[alpine sable]

?

[languid haven]

first do the hexagon

[alpine sable]

ok ok

[languid haven]

oh wait

im dum

its an octagon

lemme check it out

[alpine sable]

xd

[languid haven]

wait chief

[alpine sable]

dont worry

yes?

[languid haven]

i mean wait ill try to solve ti

[alpine sable]

ok ok ty

One friend got like 391.60

391.60m

So I got

[languid haven]

got it

[alpine sable]

A = N x S x A over 2 A= 8 x 5 x 12.08 and then im stucl

stuck

You got it?

😄

Wait

[languid haven]

ye

[alpine sable]

How much did you got?

get

[languid haven]

which one is the question

the octo or hexa?

[alpine sable]

this one
