Ok so the equation for AI might be

cash flow (1-(days/total days in coupon period))
Idk that helps

Yeah I know that much, thank you, I'm having trouble just discerning the days since the last coupon payment from the dates given is all.

Bonds usually pay interest on the first day of January and July

That's usually what semiannual implies.

Ok.

@SamanthaM awesome, I think this is the first homework help of the new academic channels!

Would anyone @here be willing to read my rought draft for a paper I'm writing on this video:

https://www.ted.com/talks/david_miliband_the_refugee_crisis_is_a_test_of_our_character

Also any specific sources to help back up my statements would be appreciated

@StrawberryArmada I suggest putting the paper into a google doc, and creating a share link where anyone with the link can comment on (but not edit) the document

Good idea

This should work

Halp pls

:)

Here is @StrawberryArmada 's link again: https://docs.google.com/document/d/1AZ9CGTxATdGQ_x8RfgdQ_hg4_HkDw1hkeGIflzmxmTI/edit

@StrawberryArmada Alright dude I looked over it, left my comments and some sources I found. Hopefully someone else can give it a once over as well @here

Thanks mate. I still have a week before the finally draft

yw!

Anyone able to help with an algebra problem? Pretty basic

@Warren H shoot

9u = 6/5

How do i get to 2/15?

Multiply both sides by 5

so on the left you have 45 u

an the right the 5 on the bottom cancels out with the 5 on the top you just multiplied

so 45u = 6

then divide both sides by 45

so u = 6/45

6 is 2\*3, and 45 = 15\*3

so u = (2\*3)/(15\*3)

the 3 on top and bottom cross out

so u = 2/15

@Warren H oh you want it the way they did it in the picture? it is similar:

starting from 9u = 6/5

Your way seems easier. There's was confusing as heck

How did you know 15 x 3? Instead of 9x5?

I'm bad with fractions lol

I'll do it closer to the way they did it:
starting from 9u = 6/5
divide both sides by 9, so u = (6/5) * (1/9)

so u = 6/(5*9)

now 6 is 2\*3 and 9 is 3\*3

so u = (2\*3)/(5\*3\*3)

cross out a 3 on top and bottom

Ohh okay.

so u = 2/(5*3)

so u = 2/15

yep

So I do that every time? Divide both sides by whatever the number is?

Yep that will always work

Awesome thanks. One more, this one is a negative number. I'm guessing it works the same?

-4w = 6/7

So divide both sides by -4 and I get 6/7 * 1/4? Or -1/4

Yep:
divide both sides by -4, so w = 6/(7* -4)
6 is 2\*3 and -4 is 2\*-2
so w = (2\*3) / (7\*2\*-2)
then cross out the two on top and bottom
so w = 3/(7*-2)
so w = 3/(-14) or equivalently w = -3/14

@Warren H the second one

the negative sign stays with the number it is attached to

Okay. So I got 3/7 the first time. But it's actually negative 3/14ths? Or -3 over 14?

Yep. If you're asking if there is a difference between " negative 3/14ths vs -3 over 14" the answer is no, they have the same value

Uh. Divide both sides by 9

Oh geez

I didn't see all this

@Warren H One thing you might notice at the beginning: think about the equation -4w = 6/7

one things you might notice is that the left side is -4 * w, and the left side is a positive number (specifically 6/7)

that means w times a negative number is something positive

so whatever w is, w must be some negative number, since -4 times a positive number would be negative.

@Warren H This ^ might help as a kind of double check on your work, thinking what sign the final answer should have

Okay yeah that makes sense.

Ive been working a lot with linear equations

@Warren H Yeah they are an important building block for a lot of things but there can be a lot to keep track of when getting used to them. Any thoughts in particular about linear equations? Let us know if you have any questions in the future!

Haha I don't like them lol. The worst part of math for me is fractions, and finding missing numbers like x lol

@Warren H haha yeah if you remember up there ^^^ the first way I wanted to solve for u... first thing I did was cross-multiplied the denominators because I don't like using fractions either if I don't have to.
Are you doing this for a math major?

Yeah I will try to remember that

And nope not at all. I'm majoring in media production. This is just a required core class. Even tho I took 4 years of math in high school 🙃

@Warren H yep it's a common core req for almost everybody. welp, feel free to ping <@&387091385075105804> for help here throughout the semester!

What's AE?

@ThisIsChris

@Warren H Academic Expert, it pings everyone has volunteered to make themselves available to anyone asking questions. Lots of fellow students and teachers and former teachers here

Although pinging @here works pretty well too

Ah okay. That's good to know @ThisIsChris

If you're still here I need some clarification on a problem that I think I did correctly but it's not approving

@Warren H sure!

-2z - 4z = 19+ 4

left side is -6z
right side is 23
so -6z = 23
divide both sides by -6
so z = 23/(-6) or equivalently z = -23/6

Oh

lol I didn't do the signs right. I got 23/6 that's why

that'll do it

😆 it's really hard to pay attention to that sometimes. Especially on timed exams

Yeah, best thing I could advise is that whenever you see a negative sign ANYWHERE, double check at the end that the signs look right

if all the numbers are positive then you probably don't have to be too careful. It's just when a negative sign appears, keep going, but walk through it again at the end

Yeah that's a good way to check. I try my best lol

Anyone @here to help with another math question?

I might could. I haven't done math in a bit, but I can do things like the last question posted.

I know the answer to this question, I'm just not sure how to solve to get to it

6/9 * 3/12 squared - 4/6

Is there an equals sign?

No. supposed to solve it

PEMDAS

I meant I knew the answer

Order of operations
