I was the first one out of my 345 exam.. either I failed or did okay.. lmao.
chick next to me had like 10 equations written down on her exam paper... wtf there were 4 true/false questions and 3 were short answer, why would you even need all those equations

Anyone able to help out with this Math 157 question? It's been about 3 years now since i've taken calculus... and I was trying to help my friend with it but I can't seem to get the answer...

Any steps would be great.

^ lol seriously,
i didn't bother just drew tons of graphs haha

@ jtanner

since u have average cost, multiply ur equation by q
then you'll get cq = 900 + 4100(e^(5q-5/850) <--- your cost function
then just derive it

if i did it properly, this should be your marginal cost funct.
C'q = 4100*(5q-5/850)* e^(5q-5/850) * (5)
- throw in ur q value then calculate

Is that right? Seems way too large...

I got...

dc/dq = -900 + 4100 * e^[(5q+6)/850]*[(q/170)-1] / q^2

But I don't think it's right... I ended up with..

I think its C`(q) = (5/850)*4100*(e^(5q+5/850))

is the answer 42.42?

((900/q)+4100*(e^((5q+5)/350)/q))) Multiply this by q
=900+4100 e^(1/350 (5+5 q)) Take the derivative
=d/dq (900+4100 e^(1/350 (5+5 q)))
=410/7 e^(1/70+q/70) Plug in q=45
=410/7 e^(1/70+45/70)

It was... 42.4712. I used Wolfram Alpha to help derive the equation...

C'Q = (410/17)*e(1/850)*(5q+6)

Appreciate the help from everyone.

Lynne Quarmby, and Fredric Pio. Quarmby won the excellence teaching award last yr. I don't know how she even got it. She told us that she won't give us review questions because she doesn't want to narrow down our study. Who the f says that? And basically reading the book is not enough, you need to synthesize and connect dots in order to understand the questions on the midterm. The second worst class in my 3 years since ochem.
