1. Do not ping the Moderators, unless someone is breaking the rules.
2. Do not ping the Helper Moderators, unless there is a conflict between helpers.
3. Do not ping other members randomly for help.
4. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
5. Wait patiently for a helper to come along.
6. If the Helper has answered your question, remember to thank them with the Mathematics Ranks bot and close the thread with:

The length of the perpendicular from the pout (3,1) to straight line 4x+3y-5= 0
equals = ...... unit length.

[viral matrix]

Perpendicular distance = $\frac{|Ax_0 + By_0 + C|}{\sqrt{A^2 + B^2}}$

[tidal gyro]

Ag3nt

[viral matrix]

Where the equation is of the form Ax+By+C and the point has co-ordinates $(x_0,y_0)$

[tidal gyro]

Ag3nt

[viral matrix]

@distant plover

[distant plover]

what does this mean

@viral matrix

[distant plover]

i did it

answer = 2

[viral matrix]

Yeah

2 units

[viral matrix]

Which one?

[distant plover]

all

[viral matrix]

Do you know the point slope form?

$y - y_1 = m \bigl(x - x_1\bigr)$

[tidal gyro]

Ag3nt

[distant plover]

no

[distant plover]

whats m

m = slope?

[viral matrix]

Yeah

[distant plover]

wait

slope =

uhhh

i forgot

[viral matrix]

1/4

[distant plover]

?

how do u get it

[viral matrix]

Because the direction vector is (4,1)

[distant plover]

y/x

ok

lemme cook

[distant plover]

y = 5?

[viral matrix]

No

$y_1 = 5$

[tidal gyro]

Ag3nt

[distant plover]

how about y?

and x

[viral matrix]

y=y and x=x

That’s how an equation works

[distant plover]

ok wait

[viral matrix]

Look at the options

They’re all in terms of x and y

[distant plover]

i got this

y-5=1/4 (x-2)

[viral matrix]

Yep

[distant plover]

now lemme cook

@viral matrix

i got this

[viral matrix]

U there?

@distant plover

Multiply both sides by 4

[distant plover]

ok

[distant plover]

r u sure this is how it works

[viral matrix]

Huh? No

[distant plover]

i multiplied them by 4

[viral matrix]

It’s x-2-4y+20

[distant plover]

i corrected the 4 i made it 1

[viral matrix]

You multiplied the x-2 by 64

[distant plover]

why u didnt multiply the x by 4

[distant plover]

how

[viral matrix]

1/4 * 4 =1

[distant plover]

ye i corrected that

[viral matrix]

1/4(something) * 4 = something

[distant plover]

?

ok.

that's what i did

i corrected it

i said i fucking corrected it

from 4 to 1

?

1/4 x 4 = 1

[viral matrix]

1/4(something) * 4 = something not 4(something)

[distant plover]

?

[viral matrix]

Now instead of 64, ur multiplying by 16

Not 4

[distant plover]

whats the fucking answer

[viral matrix]

This

[distant plover]

its not an option

[viral matrix]

20-2=18

[distant plover]

ok

next question

[viral matrix]

What is sin theta?

[distant plover]

sin theta is sin theta

[viral matrix]

You don’t say

[distant plover]

opposite/hypotenuse

i guess

[viral matrix]

Look at the question

[distant plover]

what

[viral matrix]

The question u sent

[distant plover]

what about it bro

[viral matrix]

Look at it

What is the value of sin theta

?

[distant plover]

idk

its

2sin theta - sqroot3 = 0

and theta ranges between 90-270 degrees

[viral matrix]

Re arrange the equation

To get the value of sin theta

And see which value of theta in the given range corresponds to that value

[distant plover]

wait

@viral matrix

sin theta =

sqroot3/2

right?

[viral matrix]

Yeah

[distant plover]

how to get theta

[viral matrix]

It’s 60 or 120

You have to know the values beforehand

Or have reference sheet or smth

But 60 isn’t in the range

[distant plover]

how

how do u know 60 or 120

[viral matrix]

.

[viral matrix]

.

[distant plover]

my calc says 60

how do i get it to say 120

@viral matrix

[viral matrix]

Sin(180-x) = sin x

[distant plover]

what

[viral matrix]

What?

[distant plover]

whats that

[viral matrix]

sin(180-60) = sin(60)

[viral matrix]

Formula?

[distant plover]

insane

should i write that down in the steps

or sin theta = sqroot3/2 is enough ?

[viral matrix]

It’s an mcq

But if you have to write steps

Write everything

[distant plover]

like what

wait

[distant plover]

where would u get that 60 from

[viral matrix]

Sin(180-x) = sin x

x=60

For that last one, h = 100(tan 42)

m

[distant plover]

i need steps for ts

or the teacher is gonna start yapping

@viral matrix

what formula

whats the formula

@viral matrix

[viral matrix]

Tan 42 = h/100

You labelled the wrong thing 100 btw

[distant plover]

dang ok

[distant plover]

questions

[distant plover]

someone help

[thin owl]

Which question?

[viral matrix]

I think all of them

[sick geyser]

these are very fun

when you're online ping me so i can help out

[distant plover]

@sick geyser

[sick geyser]

okay

so which ones

[distant plover]

all

[sick geyser]

alright just gimme a sec

do you know matrix multiplication

[distant plover]

no

i forgot how to

[reef bane]

you mean youre trying to get help on an exam?

imconfused

[sick geyser]

search it then

[distant plover]

yes model examss

[distant plover]

why else do u think im here

[sick geyser]

fine then

[reef bane]

that is literally against the rules

[sick geyser]

dude

a MODEL exam

[reef bane]

ooaa dont help them, theyre cheating

[reef bane]

AN EXAM

[sick geyser]

...look at how long this thread has been open

[reef bane]

that doesnt matter

[sick geyser]

💀

[reef bane]

its been 7 hours, thats not a lot of time

regardless this isnt okay

if this is going to be on an exam, and theyre getting answers for an exam, thats against the rules

[reef bane]

and this, begging for answers, rudely at that

<@&775784618955505685>

[distant plover]

its called model exam

r u slow?

[reef bane]

im not interacting with you. youre extremely rude.

yk the stuff you did, so 🤷‍♀️

[distant plover]

then get out of the thread lmao

never really asked for your help

[reef bane]

you opened a public thread, darling.

[distant plover]

and it's mine

get out if u dont like it here

ur not even helping

and ur accusing me of cheating on exams

and ur cluttering

is gtfo atp

[reef bane]

for 1, i havent been talking in here for like 5 minutes atp. youre cluttering your own channel by crashing out. 2, refer to the screenshots, you might find it easier to get help if you do.

[distant plover]

get out

rn

@sick geyser

ignore that thing

now what about matrix multiplication

@sick geyser

@sick geyser r u alive

[sick geyser]

gimme a sec

im studying

[distant plover]

dang ☠️

[opal hound]

@distant plover try to be a bit nicer please 🙏
@reef bane Outdated or Test-Exams for learning are alowed. Only when you're on a gradable tesr does a issue arise

[distant plover]

ok

@opal hound can u remove his ability to send another message or even see the channel

[sick geyser]

pls do that

[distant plover]

his sheer lack of basic thinking skills are pissing me off

[opal hound]

Its on a bedsheet or so. Wouldnt make sense if not

[distant plover]

I am nice

nothing rude

I'm just pointing out a fact

[opal hound]

I cant do that, just stay off of each other if possibly

I saw that

Just calm down guys

[distant plover]

Never asked for a straight answer

we were literally solving the problem for the past 15 mins or so

[opal hound]

No need to punish someone without giving them a second chance

[signal jacinth]

Aren't they just cheating on their exam

[distant plover]

for God's sake

these

[opal hound]

Just look at the background

[distant plover]

things

[opal hound]

Guyss

[signal jacinth]

Oh i just read this

[sick geyser]

pinging mods is not a small thing buddy

[distant plover]

not to mention that there is no exam that goes from 9:49 AM GMT+3 til 4:48 PM GMT+3...

[opal hound]

Fair

Both of you just stop talking with each other flr a while and calm down

[sick geyser]

womp womp

[distant plover]

@sick geyser

x²-5x is the same as 3x or x³ right?

[sick geyser]

wdym

[distant plover]

In the question

[sick geyser]

$X^2=\begin{pmatrix}2&4\4&-3\end{pmatrix}\begin{pmatrix}2&4\4&-3\end{pmatrix}$

[tidal gyro]

ooaa

[distant plover]

ye

x^2 - 5x means we can cancel 2 matrices out right?

@sick geyser x² = 2x

2x-5x = 3x

so we can multiply the matrix by itself 3 times only and have the same result right?

[shy frigate]

any further flooding the chat with arguments will lead to mute

[sick geyser]

No.

[distant plover]

dang

ok

[sick geyser]

try to actually calculate it

do the multiplication

[distant plover]

i'll multiply x^2 wait

[sick geyser]

from here

[sick geyser]

thank you bro

[distant plover]

@sick geyser

how do i do 5x

if i run the same method it's taking no less than 20 mins

[shy frigate]

multiply each element of x matrix with 5 for 5x

[sick geyser]

good

[sick geyser]

each element multiplied by 5

then subtract the resulting matricies and gg ez

[sick geyser]

should be -12

4-16=-12

[distant plover]

fixed it

the answer is -22I

[sick geyser]

nice

aight imma be gone for a few mins

[distant plover]

alr

ima go to gym ig

@distant plover What do you need help with?

[thin owl]

For the first picture, section 2, number 2, try to draw it out. Notice what happens with vector addition.

,texsp In particular, ||$\vec{AB}+\vec{BC}=\vec{AC}$||.

[tidal gyro]

Kocher

[distant plover]

number 3*

[distant plover]

ab + bc = ac
is a rule?

theorem*

?

@thin owl

its = AD

ima go eat

[thin owl]

Yes.

[thin owl]

Yeah.

[distant plover]

i finished the rest of the hw with chatgpt

care to help me with the new one?

[thin owl]

🤨
