You got it now take it apart and solve

how do you set it up to solve it though?

If youneed anymore help with these types of problems let me know

Were you able to figure this one out erica? :D

\[\large V=xyz\]\[\large V'=x'yz+xy'z+xyz'\]

yes :3

I'm sorry haha I was trying to think about what it was that you pointed of my mistake

what are the numbers that are being derived in this case?

also how do you use the given rates to solve the problem?

Uh oh, did your brain esplode? :c

Yah if you see it step by step it might help.

thank you :3
I really appreciate you taking your time to help me learn this~

I know that we need the Area formula A=L*W*H

dV/dt

Yes :)

so we need the derivative, do we plug in the number yet? or it's still later on

-_- lol
read the sentence in all caps.

silly erica :3

lol sorry it showed up after I pressed enter o.o

ah i see :)

So if we take the derivative, we'll have to apply the product rule,

Uh oh :( Silence...
So this is the tough part huh?

yes :c

Yah tough class c: so much fun though! lol

Do you plan on taking calc 2 at any point? c: that class is harrrrd

k c:

OpenStudy froze again.. sigh have to type all that over again :( man that's so frustrating.

dang that bites, I think it's frustrating enough trying to help me o.o"

lol :)

And then we will get our solution for V'.

\[V'=[-0.2(12)(16)]+[10(-.2)(16)]+[10(12)(.3)]\]

Yah c:

and then input this into the calc
ill do it :3

-34.4

would this be the final answer?

Yes.

I understand how to do this problem better (:

k good c: i hope so hehe

there is less confusion :D

does the same idea apply to a cone? just a different volume formula?
