[plain plaza]

id like to know how to do the stuff i need but i’m just

so sleepy

[rich roost]

That’s fair

Here it’s asking you when V gets doubled

[plain plaza]

yeah

my friend showed me how to do it with graph

but i dunno if it should be 6 or 7

[rich roost]

7, it’s asking for more than double

6 is a bit under doubling

[plain plaza]

ooh ok

[rich roost]

So you round up

So you have to have to use this formula for c)

You isolate t and that’s the answer

You have to use logarithms so I can just do it if you forgot how for this stuff

[plain plaza]

i think i figured out how to do it but i think i put the wrong number for t for the second bit???

or maybe it’s all wrong idk

[rich roost]

For the second part of 8) it’s fine

But third part is wrong

[plain plaza]

oh really?

ooh

what about it

[rich roost]

You have to pose this and isolate t

It’s gonna be less than 2 years

*a bit more

Your answer is 4 times the actual answer

I think you forgot the 4 in the exponent

But otherwise it’s the right answer

[rich roost]

You put the right numbers but I forgot to check the calculation, it’s 5478.95

Idk how you got something different tho

[plain plaza]

ooh

what should i have done

[rich roost]

For the second one or third one

Cause second one is just calculator usage

Third one, see this x?

It should be 4x

Thats the thing you forgot

[obtuse pebble]

@plain plaza Has your question been resolved?

[plain plaza]

ooh ok

[obtuse pebble]

@plain plaza Has your question been resolved?

[plain plaza]

is it gonna ask me this forever

[rich roost]

You have to answer yes for it to end lol

I mean is there something left

[stone flint]

[timid silo]

What's the objective + what have you tried

[stone flint]

To solve

Tried : nothing

[patent jetty]

What do u want to solve for

[stone flint]

How do I even start

[timid silo]

Are u trying to solve for y or x

[stone flint]

Shouldn't I be trying to solve both

[timid silo]

I mean you got to have something to solve for, the first one is just an ellipse

[stone flint]

How can u tell

[timid silo]

Discriminant I guess

But that's outside of the point

We need to know what you are solving for

[timid silo]

Grade 8 linear equations

[earnest elk]

,rotate

[earnest elk]

have you tried anything?

[timid silo]

Yes

[earnest elk]

show your working

[timid silo]

I have multiplied 2 by 2x and -3

Can u explain me from beginning plz

[slow hornet]

the question is asking to find x, correct?

@timid silo

[timid silo]

Yes the question is asking to find x

[slow hornet]

Alright, you see the "x-5" as the denominator, correct?

you can multiply both sides by "x-5"

[timid silo]

Ok

[slow hornet]

does that help a little? @timid silo

[timid silo]

Next step

[slow hornet]

after that, look at the left hand side

do you see that the "x-5" has been cancelled out?

[timid silo]

I didn't understand?

[slow hornet]

this is because when you multiply a number by the same number in a denominator

the numbers will "cancel out"

[timid silo]

Can u plz show me on paper

[slow hornet]

alright

$$(x-5) \times \frac {(x+2)(2x-3)-2x^2+6}{x-5}$$

[warm shale]

hahahxrvy

[slow hornet]

this is your left hand side after you multiply the x-5, correct?

you can see that after multiplying x-5 to the fraction, there will be an "x-5" on top and on the bottom

[timid silo]

Yes

[slow hornet]

because of this, you can cancel them both out, as diving a number by itself will equal to 1

does that make sense?

because you can think of this as

replacing the fraction with a division symbol @timid silo

[timid silo]

Ok

[slow hornet]

so because that is gone, what are you left with?

on the left hand side

[timid silo]

Next step

[slow hornet]

what you do on the left hand side, you also do to the right hand side

so multiply the right hand side, (which is 2) by "x-5"

got it?

[timid silo]

Ok

So is it 10

[slow hornet]

yep

that is what i got

x = 10

do you want me to show you the full working out

[timid silo]

Ya

[slow hornet]

here you go

hope this helped

[timid silo]

Ok

[slow hornet]

if you got something like this, you should be right

[timid silo]

Thank you

[slow hornet]

You're welcome

[uneven night]

. In a given bacterial population, the number of bacteria changes at a rate proportional to the number of bacteria. The proportionality constant is 0.1 h^-1. The number of bacteria at time zero is 1000. a) Set up a differential equation for the number of bacteria at time t and solve it. Also calculate the number of bacteria at time t = 6 h. b) Calculate the time it takes for the bacterial population to double

I need only help with b

[uneven night]

Can someone help me please

Only with b)

How do I calculate the time it takes for the bacterial population to double?

Could someone help me with this? Atleast telling me how to do it would be enough

[timid silo]

1 - Use the formulas for the surface area of a cylinder, paying attention to the sides that are not exposed.
2 - Make the total area a function and minimise it.

[obtuse pebble]

@shrewd vault Has your question been resolved?

[timid silo]

what was done wrong in this solution?

[nocturne minnow]

Answer isn't exact

[timid silo]

that much is obvious bruh

[nocturne minnow]

That's why it's wrong

The process is correct

You just didn't have exact answers

[timid silo]

isn't it +36 and not -36

24*

[civic zealot]

that and the -24 should be +24

[nocturne minnow]

And that too, I mean your teacher did mark what was wrong

[timid silo]

yeah

so wait

how does it go

• • • = -

isn't + * - = - as well?

[nocturne minnow]

Because a negative times positive equals a negative

[timid silo]

and pos * neg?

[nocturne minnow]

Yes because multiplication is commutative

[timid silo]

oh, okay

btw, how is root(12) = 3.4?

acc it is, nvm

that's all for now

thanks guys

btw, how do i close this

[timid silo]

how do i know when i have to excrete?

bcz a 3rd step in photomath was my friend's 1st step

i'm interested in why couldn't i stayed with 3x-x^2 and 6-2x

[dark mango]

wdym

[timid silo]

excrete

wdym wdym

[timid silo]

i literally just explained it

[dark mango]

I dont know what that word means in this context

[timid silo]

oh

like

to cut down

the number

[dark mango]

factor?

ohhh

[timid silo]

yeah

LMAO

[dark mango]

I wouldnt say excrete in the future

fyi

[timid silo]

i won't bbg dw

help me out there

[dark mango]

You dont have to factor

it just helps make it easier

[timid silo]

how do i know when i can and can't use it

[dark mango]

intuition I guess

there is no defining characteristic to immediately tell you to factor here but if you do it makes the math nicer

[timid silo]

🧍

rly?

bruh

[dark mango]

you didnt have to factor

you could have just multiplied by both denoms as is

and got to your solution

its just uglier

[dark mango]

I guess see if factoring gives a common factor

[timid silo]

what is a common factor

and how do i check that

[dark mango]

like they both have

(3-x)

[timid silo]

ohh thst yes

[dark mango]

by factoring

[timid silo]

btw sry if im asking like dumb questions

its like 3:30am

[dark mango]

its okay

[timid silo]

LMAO HAHAHAHA

💀

thanks

[dark mango]

its just intiution and practice

[timid silo]

ill just do it every time

and if there is no common factor

ill just erase it

[dark mango]

yeah that works

[timid silo]

thank you once again

[signal ember]

can anyone guide me through these problems

[signal ember]

not a test btw, its a checkpoint so like hw

[tranquil quiver]

which one are you stuck on

[signal ember]

all 4

im just a bit confused

[tranquil quiver]

do you know log laws

[signal ember]

yea

so 1 a

i think i do

log 2500 - 2 log 5

so i do log 2500 - log 5^2

[tranquil quiver]

Yeah

[signal ember]

then log 2500 - log 10

[tranquil quiver]

no

[signal ember]

then log (2500/10)

[tranquil quiver]

it's 5 to the power of 2

Not 5 times 2

[signal ember]

oh

wait so 25

[tranquil quiver]

5^2 = 5*5 = 25

[signal ember]

yea

[tranquil quiver]

yes

[signal ember]

so then log (2500/25)

log(100)?

[tranquil quiver]

also log by itself is implciity base 10 right

[signal ember]

yea

[tranquil quiver]

yeah

[signal ember]

ohhh

[tranquil quiver]

And then 10 to the power of what gives 100

[signal ember]

2

10^2

[tranquil quiver]

yes

so log(100) = 2

[signal ember]

ohhhhh

can we try the one with fractiom

[tranquil quiver]

1b)?

[signal ember]

yep

[tranquil quiver]

sure

Do you also know your exponent laws

[signal ember]

yea i think so

[tranquil quiver]

okay

Where do you get stuck

It's a similar process to 1a

[signal ember]

log 8 (3/64) + log 8 (1/9) ^ 1/2

[tranquil quiver]

yeah good

[signal ember]

then log(3/64) * 2/9?

because i cross multiply 1/9 and 1/2

[tranquil quiver]

wut

[signal ember]

uh

wait nvm

[tranquil quiver]

you multiplied again

[signal ember]

yea...

[tranquil quiver]

It's to the power of 1/2

which is the same as what

[signal ember]

that gives me 0.333333

= 3/9

then log(3/64) * 3/9?

[tranquil quiver]

did you use calculator for that

[signal ember]

yea..

[tranquil quiver]

you shouldn't

[signal ember]

tech can be 1/3

[tranquil quiver]

Use your exponent laws

[signal ember]

add the exponents

[tranquil quiver]

do you know $x^\frac{1}{2} = \sqrt{x}$

[warm shale]

dog.

[signal ember]

ohhh right

[tranquil quiver]

also $(\frac{a}{b})^n = \frac{a^n}{b^n}$

[warm shale]

dog.

[signal ember]

yea i know this one

[tranquil quiver]

$(\frac{1}{9})^\frac{1}{2} = \sqrt{\frac{1}{9}} = \frac{\sqrt{1}}{\sqrt{9}} = \frac{1}{3}$

[warm shale]

dog.

[tranquil quiver]

makes sense?

[signal ember]

yea

[tranquil quiver]

so then you have

[signal ember]

then log8(3/64) * 1/3?

[tranquil quiver]

not quite be careful with parenthesis

you get the product inside one log

[signal ember]

log8(3/64 * 1/3)?

[tranquil quiver]

yeah

then the 3's cancel out

[signal ember]

1/64

[tranquil quiver]

$\log_8 {\frac{1}{64}}$

[signal ember]

log8(1/64)

[tranquil quiver]

exactly

oops

[signal ember]

i seeeee

[warm shale]

dog.

[signal ember]

can we go through 2a and 2 b as weel

well

[tranquil quiver]

wait

this isnt done

[signal ember]

oh right

[tranquil quiver]

you can evaluate it down to a number

[signal ember]

8^x = 1/64

[cold abyss]

are yall done i have really easy problem that i get any good help

im sorry to interupt

[tranquil quiver]

#❓how-to-get-help

[tranquil quiver]

hold on

[cold abyss]

i have a channel

[tranquil quiver]

first can you write 64 as eight to the power of smth

[tranquil quiver]

waitthen

[signal ember]

8^2 = 64

[tranquil quiver]

yeah

hence

$\frac{1}{64} = \frac{1}{8^2}$

right

[warm shale]

dog.

[tranquil quiver]

also do you know this fact

$x^{-1} = \frac{1}{x}$

[signal ember]

yea

yes

[warm shale]

dog.

[tranquil quiver]

so $\frac{1}{8^2} = 8^{-2}$

makes sense?

[warm shale]

dog.

[signal ember]

uhhh

ohhh

[tranquil quiver]

yeah?

[signal ember]

yea

[tranquil quiver]

then

$\log_8 (8^{-2}) = -2$

[warm shale]

dog.

[tranquil quiver]

makes sense?

[signal ember]

wait so we started with log8(1/64)

[tranquil quiver]

yes

but we found 1/64 = 8^-2

[signal ember]

right

so log8(8^-2)

[tranquil quiver]

so what do you need to raise 8 to in order to get 8^-2

of course you need to raise it by the power of -2

[signal ember]

-2

[tranquil quiver]

you can also just use ur log laws

$\log_8 (8^{-2}) = -2 \cdot \log_8 (8) = -2 \cdot 1 = -2$

[warm shale]

dog.

[signal ember]

oh yeah

i can move it down

[tranquil quiver]

yeah

[signal ember]

i see

[tranquil quiver]

okay

what part are you stuck on for the q2

[signal ember]

1/3 log a + log (c-4)

log a ^1/3 + log (c-4)

log(a^1/3 * c-4)

is that it?

[tranquil quiver]

make sure to use parenthesis

[signal ember]

because its in a single log

[tranquil quiver]

log(a^1/3 * (c-4))

yeah

[signal ember]

oh

wow okay

[tranquil quiver]

since you need to multiply the whole expression

[signal ember]

and 2b is just log x- 2 log y + log (-z)

so then

[tranquil quiver]

make sure you dont forget the restrictions part

[signal ember]

log (x-2 * -z /y)

[tranquil quiver]

hold on

wut

the x -2 isnt in the log

its

$\log(x) -2\log(y) + \log(-z)$

[warm shale]

dog.

[signal ember]

oh

wait

log (x) - log y^2 + log -z

so first

[tranquil quiver]

you can combine them in any order doesnt really matter

[signal ember]

im changing -z to square root z

[tranquil quiver]

wut

hows that work

[signal ember]

nvm

its ^1/2 is root

my b

then its just

log(x*-z/y^2)

[tranquil quiver]

yeah

[signal ember]

how do i do restrictions

[tranquil quiver]

for

$\log(x)$

[warm shale]

dog.

[tranquil quiver]

what is the restriction on x

[signal ember]

cant be 0

[tranquil quiver]

hmm so can it be -1

[signal ember]

nooo

[tranquil quiver]

so whats the full restriction

[signal ember]

so x > 0

[tranquil quiver]

yes

so any input needs to be greater than zero

[signal ember]

x > 0, xer

[tranquil quiver]

so here you have

x > 0
y > 0
-z > 0
z < 0

then you can do the same for a

1a

make sure u simplify the inequality so you have the variable on one side

[signal ember]

ah okay

thanks so much for taking the time to walk me through these problems and also being a good teacher by making me do the work aswell :D

[tranquil quiver]

no problem

make sure you understand each step

then you can solve any problem which is like this

[signal ember]

Anyone got a clue how to do 1.(c)?

1/(1×3) + 1/(3×5) + 1/(5×7) + ...

= Σ 1/((2k-1)(2k+1)) from k=1 to k=n

= 1/2 (Σ 1/(2k-1) - Σ 1/(2k+1))

Now just find a formula for Σ 1/(ak+b)

Nvm that gets ugly lol

Maybe we should actually expand

= Σ 1/(4k^2 - 1)

[ruby skiff]

how come for b u switch the x and y values?

why would u not just do tan^-1(1/-1.7)

wait nvm

[winter ether]

im not sure what youre asking there, it doesnt swap. tan(t) = O/A = y/x

[ruby skiff]

yea sry I was short circuiting for a second

[winter ether]

all good it happens

[ruby skiff]

btw man wut is the difference between the straight lines and the bent ones

[winter ether]

the bent line represents the size of the angle, aka how much it has to turn

the straight line represents how far out you need to go, so the size of the hypotenuse in your right triangle

[obtuse pebble]

@ruby skiff Has your question been resolved?

[ruby skiff]

wait another thing is why do we find differenct quadriants?

like if u look at b

instead of finding the one in 4 we find teh one in 2?

[winter ether]

the inverse functions are a little weird and only work in particular quadrants

its been a while so I forget which one tan is, I tihnk it works in the first and second, though

[ruby skiff]

na tan is only positive in the first and third

[winter ether]

its not about where its positive I think

[ruby skiff]

oh its the negative

[winter ether]

no I think you want a mix

[ruby skiff]

btw could u help me with this too?

[winter ether]

ahh thats why I was imagining it shifted over one

[ruby skiff]

its like for b i got 1

but it is actually -1

is it bc on the unit circle the x is negative?

[winter ether]

well 3pi/4 is in the second quadrant

yeah

x is negative, y is positive, so their quotient is negative

[ruby skiff]

yea but i thought the hypotnus could not be -

[winter ether]

the hypotenuse cant, but that's not what you're solving for

[ruby skiff]

oh the angle right

[winter ether]

also no\

youre solving for the ratio between the y and the x

tan(3pi/4) inputs an angle -> outputs y/x at that angle (on the unit circle, so radius 1)

[ruby skiff]

oh so we solving for the radiant ratio

[winter ether]

uh, not sure what that means

[pastel lichen]

im doing a limit

[pastel lichen]

of lim x-->-2 of 1/x+2

but its been a hot min and i dont remeber what to do here

normally you can factor or use lh rule but i dont think so here so is it just DNE ?

[sharp pecan]

well, what does y approach as it becomes 1/0?

[pastel lichen]

nothing cause you cant have 1/0?

[sharp pecan]

nononon wait

its a limit

it approaches 1/0

but its not actually 1/0

[pastel lichen]

hmm

[sharp pecan]

let me ask different

what is 1/n, where n is some extremely, extremely small number?

almost 0, but just not 0 enoigh

[pastel lichen]

near zero but probably not touching zero

[sharp pecan]

ah no

1/2 is 0.5, 1/1 is 1, 1/(0.5) is 2

1/(0.25) is 4

[pastel lichen]

infinity ?

[sharp pecan]

yes

[pastel lichen]

hmm

but i thought

[sharp pecan]

thats the answer

[pastel lichen]

you only do that

if its like

lim x-->2^- or +

[sharp pecan]

whats that?

[pastel lichen]

like

as x approaches 2 from the left or the right

[sharp pecan]

in your case its both right

[pastel lichen]

cause all i know here is that x is apporaching 2 but not from which direction

[sharp pecan]

posetive infinity

well you can try that out no

1/(0.0000000000000000000001) and 1/(-0.0000000000000000000000001)

[pastel lichen]

yea and thatll say if its pos or neg infinity but it dont have a direction ?

[sharp pecan]

its posetive and negative infinity

[pastel lichen]

so it dosnt exist then ?

because if the limit is from both positive infinity and negative infinity it dosnt exist

[sharp pecan]

true

in our class we had to write both down, so if no direction was given but the limit is different, we had to say it becomes a from the left and b from the right

but it seems you can also write it has no solution

since limit from the right and left are different for you

[pastel lichen]

what about

lim x-->-2 of 1/(x+2)^2

[native shuttle]

hey

[native shuttle]

is this mine or yours now?

[final thunder]

yours

[native shuttle]

oh

great

so quick question

if I‘m trying to find the interest rate at which 2 projects would have the same npv, do I make an equation, with one project on each side, with the interest rate being x?

[unique kettle]

That sounds right

NPV of A = NPV of B

[native shuttle]

it gave me a weird number though

but tbh, the npv I got was wrong anyways

[unique kettle]

What did it give you.

[unique kettle]

Sometimes cash flows with a lot of direction changes between positive and negative can give weird IRRs

[native shuttle]

aah fuck

I figured it out lmao

[unique kettle]

Correct me if I’m wrong because this has slightly different notation but PV of A should be 1400?

[native shuttle]

yes

[native shuttle]

absolutely

[unique kettle]

And then you probably made the same mistake with B

[native shuttle]

yes

the mistake was me trying to get it for one year earlier than I was supposed to

[unique kettle]

You discounted the first payment, on accident, should probably resolve your second part to that question lol

[native shuttle]

yup

got it right now

hahah

[knotty crow]

,rccw

[nocturne schooner]

u got anythign?

<@&286206848099549185>

[timber fox]

for part a)

consider a f(x) with degree 2 and vertex at the point (-1,2)

and understand that the inverse of a function is that function flipped on the y=x line

[nocturne schooner]

ok

[timber fox]

wait

im trolling a little bit

need to think of another example

ok

pretty sure a) may be true

as the function to be invertible has to be be one to one so it will go from neg inf to pos inf, so when you flip it, they will cross at some point

[nocturne schooner]

what

[narrow vault]

clarkie are you reading the question right

[timber fox]

potentially

not

[narrow vault]

i think you're overthinking a bit

[nocturne schooner]

its easy

but nto for me

[narrow vault]

although it's actually not all that simple to explain without just saying the right answer maybe

and idk what your teacher has/hasn't taught

for starters, for a function y=f(x), if you're trying to find its inverse, what's the first step you take

[nocturne schooner]

u swap y for x

?

im trying to self learn this stuff its hard

[narrow vault]

ok, so you have the inverse $f^{-1}(x)$ satisfying $x=f(y)$

[warm shale]

IV

[narrow vault]

so if $(x,y)$ is a point on $y=f(x)$, can you find a point using $x$ and $y$ that's on $x=f(y)$?

[warm shale]

IV

[nocturne schooner]

u sub x and y into x = f(y)?

[narrow vault]

that requires knowing the function f

can you find a point that is on x=f(y) without having to know what f is, given that (x,y) is on y=f(x)

[nocturne schooner]

idk how

[narrow vault]

notice how x=f(y) and y=f(x) look really really similar 👀

[nocturne schooner]

is it the reflection of the point on y=x

or something idk

[narrow vault]

it is, but you should be able to represent the point using 2 values

[nocturne schooner]

i am lost

what 2 values?

[narrow vault]

i guess an example should help (and give away everything)

let y=f(x)=2x, it's known that when x=1, y=2 so (x,y) = (1,2) is on y=f(x)

then finding the inverse of f you start with x = f(y) = 2y, what's the point corresponding to x=2?

[nocturne schooner]

1,??

Im lacking on fuctions i need to go bac to basixs

[narrow vault]

these points are represented in the form (x,y)

[nocturne schooner]

(2,-1)

?

(2,1)

I probably will give up on this question and go relearn basics of functions cus i dont think i understand

[limber gazelle]

Can someone help fully explain the steps taken to get the answers that they did on this problem please.

[limber gazelle]

I especially do not understand the t = 4 months and how that fits in to the total calculation, is it multiplied, divided or what?

[narrow fiber]

They have an equation interest = P • r • t

And that equation requires t in terms of years

So you convert 4 months to __ years

[limber gazelle]

I understand but I can see the ansers but need to know how they worked through it to get those answers.

[narrow fiber]

Ok so first up is the equation
I = Prt
I: Interest
P: principal
r: rate
t: time

The question wants to find out what is the interest if you miss payment no.4

[limber gazelle]

yes

I pretty much just do not understand what they did with the time, is it multiplied, divided or how does it work into the problem?

[narrow fiber]

The time is 4 months right?

[limber gazelle]

yes

[narrow fiber]

We want that in years

[limber gazelle]

yes

[narrow fiber]

We know that
12 months = 1 year

So
4 months = ?? years

What is ??

[limber gazelle]

12

[narrow fiber]

The 12 became 1, the 4 becomes 12?

If the 12 becomes 1, the 4 should become 1/3

The general equation should be
Time in years = time in months divided by 12

[limber gazelle]

ok but what then do you do after knowing this/

[narrow fiber]

You plug in the 4 into "time in months

Time in years = 4 divided by 12

[limber gazelle]

ok so what would I do if it were 5 months?

[narrow fiber]

You would plug in 5

And get 5/12

[limber gazelle]

so what then would I do with the decimal?

[narrow fiber]

You would keep it as a fraction until the very end

And then you'd round it however many places you need (usually into just the cents place)

So in our question, how much is the time in years?

[limber gazelle]

I was trying to see how in the beginning with the example if it is kind of like this problem at all fully I understand how to do this one to a certain point up until t this is why I asked about 5/12

because this asks me about fifth month I wasnt sure if its worked out different then the example

because when I do 5/12 then it turns into a decimal

[narrow fiber]

Decimals don't change how math works

The math will work the same exact way

Just the numbers are different

[limber gazelle]

how would I do 5

I just do not understand how this is worked can you show me please.

[narrow fiber]

You would do
Time in years = time in months divided by 12
And since you know time in months = 5, you get
Time in years = 5 divided by 12
t = 5/12

And then plug that into i = prt

[limber gazelle]

how do you plug it in, that is my problem that I do not understand and is what I have been trying to ask.

[narrow fiber]

i = pr(5/12)

$I = pr\frac{5}{12}$

That is how you plug it in

(Btw sorry if me constantly saying "plug it in" instead of "substitute that in" bothers you)

[limber gazelle]

I am trying to help my daughter with this problem, her teacher just showed the answers but did not fully explain how to do the work, step by step.

[narrow fiber]

So did that explain it?

[limber gazelle]

so basically i still do not get it due to the fact it is not explained on how they got to the final answer

they gave that example with no explaniations at all.

I need to know do you multiply, divide or the exacts steps.

so I can fully understand how to help her to understand it.

[narrow fiber]

Should I type in general language from now on "time in years = time in months divided by 12" or in math language "t_y = t_m/12"?

Which do you prefer

[limber gazelle]

please yes general language.

[narrow fiber]

Ok, so we have "Interest = principal multiplied by rate multiplied by time"

The question said that "you bought a computer for $945.00 plus 7% sales tax"

That translates to "principal = $945.00 plus 7% sales tax"

Correct?

[limber gazelle]

yes

[narrow fiber]

Now what does "$945.00 plus 7% sales tax" mean?

It means "1.07 multiplied by $945.00"

(the 1.07 is because the tax is 7%, if it was 8% then the number would instead be 1.08 and so on)

[limber gazelle]

yes that I understand

[narrow fiber]

So we have so far "principal = 1.07 multiplied by $945.00"

[limber gazelle]

ok

[narrow fiber]

Which becomes "principal = $1011.15"

Now we have found the principal

Next up,

[narrow fiber]

We also need the rate

[limber gazelle]

20.99

[narrow fiber]

don't forget the %

[limber gazelle]

yes

[narrow fiber]

"Rate = 20.99% or 0.2099"

Next up,

[narrow fiber]

We also need the time

The time must be in years for the equation to work

We have "time = 4 months"

We need to use another rule

"time in years = time in months divided by 12"

So because we know "time = 4 months",

We can plug that in and get "time in years = 4 divided by 12"

[limber gazelle]

3?

[narrow fiber]

4/12 is the same as 1/3

So we have "time in years = 1 divided by 3"

[limber gazelle]

ok

[narrow fiber]

What is the value of 1/3 (in decimals)?

[limber gazelle]

0.33333

[narrow fiber]

Yup

Should we use the fractional version or the decimal version?

[limber gazelle]

not sure

[narrow fiber]

Let's go with the fractional version

So now we have found all of the variables

[narrow fiber]

1

[narrow fiber]

2

[narrow fiber]

3

Now we can plug them into the original equation

"Interest = principal multiplied by rate multiplied by time"

"Interest = $1011.15 multiplied by 0.2099 multiplied by 1 divided by 3"

Does that make sense?

[limber gazelle]

yes

[narrow fiber]

And if you do the calculation on that you get your answer

I got 70.746795

[limber gazelle]

ok so what about the problem she needs to solve with the 5/12 for time, it can't be reduced? so this I do not understand either.

[narrow fiber]

It will stay 5 divided by 12

And the final equation will look something like "Interest = $1011.15 multiplied by 0.2099 multiplied by 5 divided by 12"

[limber gazelle]

so then in decimal it is 0.41666666667, so we do not use the decimal, just take and multiply by 5 then divide by 12 instead?

[narrow fiber]

Yup exactly

[limber gazelle]

ok thank you I will have her try and see if it works, then I will let you know, and ty

[narrow fiber]

Np, glad to help

[limber gazelle]

I think it helped her, her answer is 56.98 if her calculations and your guidance is correct, anyways thank you again

[narrow fiber]

Yup that's exactly the right answer

[limber gazelle]

I am so happy you could help me to help her, thank you, it was very much appreciated.

[narrow fiber]

Gladly, 😊

[still rivet]

Can someone explain how to find a vector that is both parallel to a plane and perpendicular to a line? I can find the vector with one condition, but I don't know how to find the vector with more than one condition

[brisk matrix]

find a vector that is orthogonal to the line and the plane’s normal

[still rivet]

so i should fine the normal vector of both the line and the plane and find the cross product of that?

[brisk matrix]

find the cross product of the line’s direction vector and the plane’s normal

notice that if the line’s direction and plane’s normal are parallel, you’ll get the zero vector, but you should be able to consider that case separately (just take any vector on the plane)

[still rivet]

ohh okay got it thanks!

[ruby path]

$\int \frac{\sqrt{\cos 2x}}{\sin x} dx$

[warm shale]

NEONPerseus

[ruby path]

Man where have we come from there's exactly one number in this math question

[warped agate]

use cos2x=cos^2x-sin^2x
write sin as tan/sec
and cos as 1/sec
substitute for tanx

i think ull get it

[ruby path]

Hmm

[warped agate]

it will be long tho

[ruby path]

Yeah that's expected

[ruby path]

I think I got a better way

If I put sin into the square root

I get root of cot squared - 1

Then I take cot = sin

And figure some shit out from there

nvm I should use sec not sin

[warped agate]

ya

my mother, who is a math major is telling me that in 12 less than 15
12 is first.
12-15 is (-3)
but i think it is 15
15-12 is 3
so which one of us is right?
