if you're so impatient, go pay for a tutor

[zenith arrow]

if i were you i'd go pay for sum bitches

u didn't help lmfao

noob

[zenith arrow]

go cry

[digital orbit]

Why would you purposefully antagonize the people here to help you

do you not want help?

[zenith arrow]

ofc i want help

but i don't like this guy

[digital orbit]

then act like it

otherwise you will have to find help somewhere else

[zenith arrow]

so paul needs to organize 8 books

4 literature 3 history 1 math

the 4 literature books need to be next to eachother

meanwhile math and history can be in any order

[restive river]

hello, i was wondering about this translation thing im doing rn, basically theres this graph and i have to translate the coordinate plane and basically cool and all, i have (4,4), but theres a problom here... its also asking me to move 2 units to the right and 3 units down but i cant do that since the graph is so small. What do i do?

[restive river]

<@&286206848099549185>

what do you want to calculate ?

[restive river]

it says here "translate the figure 2 units to the riht and 3 units down"

basically i do A(-1, 3)

then B(1,1)

then C(4,4)

after i get to those points

i go 2 units to the right

and then 3 units down

multiple it by
[R_idenity, [2,-3,0]',
0,0,0,1]

im just a bit frustrated because theres not enough room on the graph to move 2 units right

[restive river]

bro

theres no mulitplying in translation

omg

i thought you were using a transformation matrix

got confused by that (4,4)

sorry about that

[rotund root]

i dont really know how to approach part a (finding h in terms of k)
thanks!

[gleaming shell]

i know this question is the (number of sides on the die )X ( 2 X times the amount of time you throw the coin)

does anyone know how i should phrase this question

[regal torrent]

-D/4a

That's teh y coordinate of vertex ig

[rotund root]

in terms of k
and idk what the x-intercept has to do with the vertex

[regal torrent]

k is a root so

[rotund root]

yes

[regal torrent]

f(k) =0

And k is 2p

Ig

[rotund root]

i get that

[regal torrent]

And use h=-D/4a

Isn't it enough information

[rotund root]

oh ok

[regal torrent]

And f(0) =0

[rotund root]

yes

thank you

[normal phoenix]

ohh need help with this

[normal phoenix]

well x=24/y

so now i gotta sub 24/y instead of x in each place

😔

[midnight dirge]

yes

[normal phoenix]

isnt there an easier way

[midnight dirge]

💕

hm

[normal phoenix]

🥲

[midnight dirge]

well

[normal phoenix]

just by looking at it its gon take ages

[midnight dirge]

both times the stuff appear its

[dark tundra]

you can solve for (y-x) in equation 2 ig

[midnight dirge]

y-x

so aft u sub u get

y-x=y-24/y

then

let a=y-24/y

solve for a

[normal phoenix]

im with u

[midnight dirge]

then sub back

[midnight dirge]

aww

[normal phoenix]

isnt $(y-x)^2= y^2-2xy+x^2$

[midnight dirge]

💕

[normal phoenix]

$xy=24$

[woven radish]

Kssenia

[midnight dirge]

yea but

[normal phoenix]

a little shortcut

[dark tundra]

why are there two y^2?

[midnight dirge]

just let that =a

[normal phoenix]

oh oops

[midnight dirge]

then solve

its a quadratic

[dark tundra]

but yeah spirit’s solution works

[midnight dirge]

wot

of course

im a high ranked cultivator

[normal phoenix]

okay

[midnight dirge]

[normal phoenix]

il let a be y-24/y

[midnight dirge]

yes

[normal phoenix]

just putting it again here (dont mind that)

just
$(y-x)^2-7a+10=0$

[woven radish]

Kssenia

[normal phoenix]

should i switch x for 24/y?

[midnight dirge]

er

no like

$a^2-7a+10=0$

[normal phoenix]

OOOO

[midnight dirge]

that

[normal phoenix]

im s o dumbbb

[midnight dirge]

no

it happens

issok

[normal phoenix]

then its just 5 and 2

one sec

[midnight dirge]

yes

[normal phoenix]

$(a-5)(a-2)=0$

[woven radish]

Kssenia

[normal phoenix]

a=5 a=2

[midnight dirge]

then sub back

[normal phoenix]

a is also y-x

$y-x=5$

[woven radish]

Kssenia

[normal phoenix]

$y=5+x$

[woven radish]

Kssenia

[normal phoenix]

and then the other a

[midnight dirge]

just this lol

anw i think u got this

imma fly

🪵

[normal phoenix]

have a safe flight

[restive river]

wait @normal phoenix

what do u get

i want to make sure of something

[midnight dirge]

LOL

tryna sell insurance

[normal phoenix]

i somehow got 0=0 💀

[midnight dirge]

um

yay

[normal phoenix]

if y=5+x

hehehe

[midnight dirge]

a=y-24/y

could we use this

[restive river]

[midnight dirge]

could u use this

[restive river]

no

[midnight dirge]

wow

is that because im a women

kinda sexist

[restive river]

exactly, you figured me out

[midnight dirge]

gonna get u cancelled

[normal phoenix]

well then if a=y-24/y and its also equal to 5 and 2 we can compare them

[midnight dirge]

but this is right

yes so

[restive river]

just sub in one of them

[midnight dirge]

y-24/y = 2

[restive river]

instead of

both

[midnight dirge]

solve for y

[normal phoenix]

$y^2-24=2y$

[woven radish]

Kssenia

[normal phoenix]

$(y-6)(y+4)$

[woven radish]

Kssenia

[normal phoenix]

e

y=6 or -4

[midnight dirge]

e

[restive river]

e

WOOO

GOOD JOB

[midnight dirge]

,w (y-6)(y+4)

[normal phoenix]

📧 dont forget this

[restive river]

if u wanna

[normal phoenix]

SURE

[restive river]

ping me if u need help, i will go back to my lame matrices

[normal phoenix]

lemme just copy the last exercise to my "organized" work

will do

[restive river]

Aighty

[normal phoenix]

here is the exercise

i think i have almost solved it

lemme shwo you my way

[orchid glade]

wow thats a way to write it ig

where r u from?

[restive river]

Hmm okay I can see some ideas

[normal phoenix]

$x^2y-xy^2=84$

[woven radish]

Kssenia

[normal phoenix]

can be written as

$xy(x-y)=84$

[orchid glade]

can u solve the quadratic?

[woven radish]

Kssenia

[normal phoenix]

as for the lower eqaution

its $(x+y)^2-5x-5y=24$

[woven radish]

Kssenia

[normal phoenix]

also

$(x+y)^2-5(x+y)=24$

[woven radish]

Kssenia

[normal phoenix]

$x+y=a= 84/xy$

[woven radish]

Kssenia

[restive river]

Wait

That was for x-y

How are u defining it for 84/xy?

[normal phoenix]

$xy(x+y)=84$

[woven radish]

Kssenia

[restive river]

?

[normal phoenix]

whoops

missed there

that was supposed to be a plus

well

hold up

[restive river]

No you were right there

The minus is correct

[normal phoenix]

well then

$-84/xy$

[woven radish]

Kssenia

[restive river]

No

Because

[normal phoenix]

then it would be x-y

what should i do here

[restive river]

$x-y = \frac{84}{xy} \to -x+y = \frac{-84}{xy}$

[woven radish]

♡LexQa♡

[normal phoenix]

well then il keep a as x+y for now

[restive river]

To make it x+y, add 2y to both sides

so $x-y + 2y = \frac{84}{xy} +2y \to x+y = \frac{84}{xy} +2y$

[woven radish]

♡LexQa♡

[normal phoenix]

equal to a?

because it equals to x+y

[restive river]

Sure, but this is going to be absolutely pain and probably won't get you anywhere easy, we have to simplify first

[normal phoenix]

so what do u suggest

[restive river]

Hm

[restive river]

Actually

[normal phoenix]

oh

we can find out x or y value from second eqation

[restive river]

Carry on with this

[normal phoenix]

$x^2-2xy+y^2+5x-5y-24=0$

[woven radish]

Kssenia

[restive river]

There are a lot of ways to solve this I think, just trying to find the one that won't take as long

[orchid glade]

[hasty ferry]

i have an idea

[normal phoenix]

$(x-y-3)(x-y+8)$

[woven radish]

Kssenia

[hasty ferry]

yes that

[restive river]

Oh okay u r going that direction

[normal phoenix]

either x-y-3=0 or x-y+8=0

[restive river]

Okay that sounds good

[normal phoenix]

then find out x1 or x2

[hasty ferry]

nice

[restive river]

Yeah that works

[normal phoenix]

$x1=y+3$
$x2=y+8$

[woven radish]

Kssenia

[hasty ferry]

so we get 2 options for x-y

and put it in the first equation

we get xy

[restive river]

Factorise your equation first

[hasty ferry]

uh

sorry im korran so i dont know how to explain this

[normal phoenix]

well then $xy(x-y)=84$

[woven radish]

Kssenia

[hasty ferry]

quadratic equation

[restive river]

yeah u already know ur x-y

[hasty ferry]

and xy

[normal phoenix]

so just put it there

[hasty ferry]

so find out x+y

and make a quadratic equation with the solution of x and y

[normal phoenix]

if x-y-3=0
x-y=3

xy(3)=84

[restive river]

Yeah u know the other x too

[normal phoenix]

exactly

[restive river]

You have to make it a quad like they said

[normal phoenix]

3y(x)=84

x=y+3

[restive river]

Yeah

[normal phoenix]

3y(y+3)=84?

[hasty ferry]

yes

[normal phoenix]

[restive river]

Expand the thing

[normal phoenix]

[restive river]

That's how I do it 😵‍💫

[hasty ferry]

nice

ok this is definatly sqrt lol

[restive river]

Very nasty sqrts

Use quady boy

[hasty ferry]

[restive river]

DEUTSCHLANDDD

Anyways

Last question before trig :00

[normal phoenix]

YES

okay

now 14

[restive river]

yes

hit me with it

[normal phoenix]

looks great

[restive river]

oh okay

surprisingly isnt as hard as the others

nah its fine

give it a try first, before i assist you

[normal phoenix]

first look i suspect its x/y=a

b4 i aint even do anything

im not sure tho

[restive river]

dont make it recursive

[normal phoenix]

hhehe

okay

[restive river]

yeah like

whenever u like

do u a = yada yada u want to make it one variable

because both would make ur life a lot harder

its how u solved the other two questions

[normal phoenix]

okay so not t hat way

?

[restive river]

mmm preferably not, i would modify those square roots first

[normal phoenix]

square both sides?

[restive river]

i was thinking of adding them up to be (x+y)/sqrt(xy)

hm

thats bad though

nevermind, that restricts u a lot because it means x and y can ever be positive

which is definitely not going to be the case

[normal phoenix]

im clueless

[restive river]

ohhh

i see now

i seeeeee

@normal phoenix

square both sides

very interesting stuff will happen

[normal phoenix]

lol

[restive river]

[normal phoenix]

wouldnt that give me x/y+y/x+2(sqrt/x/y)(sqrt/y/x)=100/9

bc its (a+b)^2

[restive river]

yes

[normal phoenix]

ehhh

[restive river]

simplify the square roots and add

[normal phoenix]

more sqrts

[restive river]

they go away

the square roots

[normal phoenix]

how

[restive river]

$\frac{\sqrt{y}}{\sqrt{x}} \cdot \frac{\sqrt{x}}{\sqrt{y}}$

[woven radish]

♡LexQa♡

[normal phoenix]

OOOOO

BC ITS (sqrt/x)^2

[restive river]

yeeee

[normal phoenix]

THAT WOULD JUST GIVE ME XY

[restive river]

yeeeeeah u r getting it

[normal phoenix]

im getting itt

[restive river]

smart smart

good jobb

[normal phoenix]

💃

[restive river]

so so

after all the simplifcation

what do u have

[normal phoenix]

🪩

DISCO DISCO

[restive river]

DANCE DANCEEE

[normal phoenix]

i got x/y+y/x+2xy

[hasty ferry]

lol

[normal phoenix]

??

[restive river]

yep

[normal phoenix]

LETS GO

[restive river]

correct

[normal phoenix]

then its (2xy)^2+x^2+y^2

[restive river]

now u have a lot of options to do

[restive river]

2xy squared?

[normal phoenix]

yea cuz its like

il do it in paint

[hasty ferry]

ok i dont grt what u guys are doing

[restive river]

oh wait, i think i mixed it up for u

[hasty ferry]

can i have an explanation

[restive river]

this is still 2

not xy

[restive river]

so it is x/y + y/x + 2 i believe

[normal phoenix]

no?

[restive river]

yeee but

after squaring the thing we have

$\frac{x}{y} + \frac{y}{x} + 2\frac{\sqrt{y}}{\sqrt{x}} \cdot \frac{\sqrt{x}}{\sqrt{y}}$

[woven radish]

♡LexQa♡

[hasty ferry]

are you sure you can just make it like this

[normal phoenix]

YEA

[hasty ferry]

what if y is -

[restive river]

yeah, so the two things cancel

so u have

$\frac{x}{y} + \frac{y}{x} + 2$

[woven radish]

♡LexQa♡

[restive river]

which becomes

[normal phoenix]

(x+y)^2

[restive river]

$x^2 +y^2 + 2xy$

[woven radish]

♡LexQa♡

[restive river]

yeeee

[normal phoenix]

i dont understand how it cancels

[restive river]

exactly

[normal phoenix]

we can write 2(yada yada)

[restive river]

i mean, why not? they are just the same thing divided by the same thing

like 4/4

[normal phoenix]

but what about the 2

[restive river]

well

2(1)

after u divide them all up

[normal phoenix]

ohh

[restive river]

i mean sure, here

[normal phoenix]

so

is equal to 1?

[restive river]

yeah

[normal phoenix]

okay

[restive river]

do u get get it doee i can explain further

[normal phoenix]

isnt it (x+y)^2=(3/10)^2

so just x+y=3/10

[restive river]

oh sorry, i was just talking about the numerator here, but you are still multiplying by x/x and y/y

[restive river]

so this

divided by xy

$\frac{x^2 +y^2 + 2xy}{xy} = \frac{9}{100}$

[woven radish]

♡LexQa♡

[restive river]

does it make sense to u @normal phoenix

[normal phoenix]

well kinda

why do we divide by xy

[restive river]

its because

$\frac{x}{y} + \frac{y}{x} + 2$ we had this at the beginning right

[woven radish]

♡LexQa♡

[normal phoenix]

yea

[restive river]

multiply all the thing by x/x

[normal phoenix]

it just gives
x^2+y^2+2xy

[restive river]

sorry i should've worded this better, but let me explain in a better way, we want to get rid of the fractions, so we can multiply the first term by x/x the second term by y/y and the third term by xy/xy

its just to add up the fraction

$\frac{x \cdot x}{yx} + \frac{y \cdot y}{yx} + \frac{2(xy)}{xy}$

[woven radish]

♡LexQa♡

[restive river]

this is just to make the denominators the same

we get $\frac{x^2 +y^2 + 2xy}{xy}$ from adding them

[woven radish]

♡LexQa♡

[restive river]

i am guessing it doesnt make sense to u still ahaha

alright, so how would u normally add up fractions? @normal phoenix

[normal phoenix]

like this

[red bay]

hey lexqa

[restive river]

hi

[red bay]

can u please help me after

[normal phoenix]

we know that x/y+y/x+2/1=100/9

then the common denominator would be 9xy

[restive river]

ah i am adding up just the left side

excluding the 100/9

[normal phoenix]

ah

oof

well then i understand

thanks

[restive river]

thats why it is

$\frac{x^2 +y^2 + 2xy}{xy} = \frac{9}{100}$

[woven radish]

♡LexQa♡

[normal phoenix]

yea and then cross multiply

[restive river]

yepp

[normal phoenix]

but isnt that 100/9?

[restive river]

sorry for the confusion oops

[normal phoenix]

all g

[restive river]

oh yeah it is 100/9

[normal phoenix]

alright

understood

imma get this done

take a break and start you know what

either geo or trig

[restive river]

yepp

[normal phoenix]

🙂

[restive river]

i definitely cannot ever help u with geo, but i am ready to help with trig ahah

[normal phoenix]

thanks alot

[wary fractal]

the question asks you to do this with binomial distribution. how do i do this?

[hollow pollen]

P(X_w = 3, X_b = 2) = P(X_w = 3) = P(X_b = 2)

[wary fractal]

could you explain how the substitution in this would work

not sure what p and q would be

[devout snow]

@wary fractal Has your question been resolved?

[wary fractal]

<@&286206848099549185>

[inner oyster]

p and q are the probabilities of getting a white or blue ball I believe

5/8, 3/8

[wary fractal]

how do you know which one is p and which is q? because if we assume x=3 and p=5/8 then we get 10x(5/8)^3(3/8)^2 but if we switch it around we get 10x(5/8)^2(3/8)^3

which are two different answers right

[inner oyster]

(I thought about it a bit more). The second thing you say is the chance of 3 blue, 2 white balls

ok look at it this way. assume that the exercise asks : "what is the probability that the first 3 balls are white, and the following two are blue ?"

[restive river]

Guys

[restive river]

Why is it vertical

Its for x so why isn’t it on x

[merry seal]

x = 1/2 means all points that have x equal 1/2

so the y can change

but the x is a constant

[restive river]

And for y here it is horizontal the hec

[thin gust]

<@&268886789983436800>

same thing but opposite

[fossil moth]

first i was wondering, how do you know what shape the integral will give you? is it to just plot out the numbers

[fathom nymph]

Please help express as partial fractions

[fossil moth]

@fathom nymph this is a occupied channel

[fathom nymph]

Sorry my bad

[fossil moth]

use math help available

nw

first i was wondering, how do you know what shape the integral will give you? is it to just plot out the numbers

[merry prairie]

These will not give you any shapes, because indefinite integrals with values as bounds are always constants

You could plot the function that you are integrating

like 3-x will give you a straight line going down

and sqrt(4-x^2) is a semi circle I think

[fossil moth]

well i guess im just confused on this explanation of the question

yea semi circle

[merry prairie]

So these are known equations that you see a lot

So for the straight line going down, number 70) 3-x. If you plot it. From 0 to 3 it makes a triangle

[fossil moth]

alright

[merry prairie]

The integral of a function is just the area under its curve

so in this case you find the area of a triangle of length 3 and base 3

Which would be 1/2 * base * length

4.5

[fossil moth]

1/2(3)(3)=9/2

alright that makes much more sense

[limpid parcel]

the "axiom of Euclid" in Tarski's axiomatization of Euclidean geometry says that, if r,s are rays from the origin O, if ∠(r, s) is the angle between them, if C is a point in the interior of ∠(r, s), and if C is between O and another point C', then this point C' is also in the interior of ∠(r, s)

on the other hand, the "parallel axiom" in Hilbert's axiomatization of Euclidean geometry says that, if L is a line on a plane, and if P is a point of that plane not lying on this line, then there is at most one line on this plane that goes through P and is parallel to L

I know both of these axioms are equivalent to the fifth postulate, and thus to each other, over their respective axiomatizations of neutral geometry. my question is: what is the proof of the parallel axiom from the axiom of Euclid? or, in other words: how do I prove the parallel axiom from the axiom of Euclid?

[patent arrow]

so a particle is traveling on a straight line with motion described by the equation y=f(x), if f'(1) = 2 and f"(1)=-3 then the particle is

[patent arrow]

moving forward, moving backward , speeding up , slowing down

and im suppose to select all that apply

[hybrid snow]

if the sign of f'(a) is equal to the sign of f"(a) the particle is speeding up

f'(x) determines the velocity

I'm assuming positive is Foward, negative is backward

[patent arrow]

so speeding up but moving backwards ?

i forgot it is f'(1) and f"(1)

[devout snow]

@patent arrow Has your question been resolved?

[hybrid snow]

It gives you values

[patent arrow]

hmm

im confused lol

is it not moving backwards cause its negative and speeding up because f is the same >?

[hybrid snow]

f'(1) = 2
f''(1) = -3

[hybrid snow]

It's slowing down. The sign of 2 and -3 are not the same

It's not moving backwards

What's the sign of f'(1)

[patent arrow]

ohh

2

i thought ya meant f'(1) and f"(1) had the same 1

[rough bane]

Hi

[rough bane]

WhTs the steps behind this

[timid sonnet]

Ok

[rough bane]

like just teps would be ok please

steps

[scenic ivy]

@rough bane

Hi, division with algebra is like this

its similar to division with normal number

for instance, for the first term, you ask yourself how many x + 3 are there in 2x^3

well none, so you move on to 2x^3 + 6x^2

you ask yourself how many x + 3 are there

[crimson hamlet]

or u can just use synthetic division

[rough bane]

it has to be long division

[scenic ivy]

well there are 2x^2 x + 3s in there, so you sinply multiply 2x^2 by x + 3 to get 2x^3 + 6x

i dont think im explaining it clearly with words

i would suggest you to watch a video

[rough bane]

its ok pls continue

[scenic ivy]

gimme a sec lemme find it

https://youtu.be/_FSXJmESFmQ

[scenic ivy]

watch this and you should be clearer

Hi, this channel is occupied

Yeah I meant like as a question to OP

[restive river]

no

[bleak sun]

so whats the slope of the graph?

[restive river]

uh

8/5

[bleak sun]

Its a speed vs time graph

So you graph speed and the current time

if his speeds the same what will the graph look like?

[storm sedge]

can i get some help with a probability question?

[storm sedge]

The Question is:
A Covid’19 Test gives positive result (for infected person) with probability of 0.9 and a negative result (for healthy person) with probability of 0.8. What’s the probability of person being negative if he had taken two separate test that had given a negative result.

What I came up with is: 1 / (2 x 0.8) = 0.625 x 100 => 62,5% for ones to be negative with taken 2 tests (idk if thats how its calculated)

[devout snow]

@storm sedge Has your question been resolved?

[polar bolt]

there are two ways to get a negative test. Either false negative (infected but getting negative) or true negative (healthy and getting negative)

[storm sedge]

so maybe the answer should be 50/50?

[polar bolt]

no because each event doesnt have the same prob

use the information given

[devout snow]

@storm sedge Has your question been resolved?

[storm sedge]

should I separate each event (A - positive and B - negative) to smaller ones (a1 - 0.1 for being positive but im not infected and a2 - 0,9 for being positive and me being infected and vice versa for B) ?

from there use the P(B not A) formula and replace A and B with the formula (a1 or a2) for A and for B (b1 or b2) formula

[polar bolt]

wdym?

[storm sedge]

im trying to find a formula that i can use

but im not sure which one

the moment i got negative i knew im on the wrong path
