For 6 on the turn in, should we assume the conical tank is full before it empties into the cylindrical tank? This may have been answered, but I can't remember.
ReplyDeleteYes, assume it began full.
DeleteFor 48, I got the line normal to the curve xy+2xy-3y^2=0 at (1,1). How do I know what other point it intersects?
ReplyDeleteYou have a system of two equations now....
DeleteHow are people approaching 5a. without the height of the tank?

DeleteI don't think you need the height...I left an h in my final answer. Here's how I approached the problem:
DeleteFirst I found the radius (base area [it's a circle] given was 400π...so 400π=πr^2). Once I got radius, I plugged it into the cylinder volume equation [V=π(r^2)h].

Uh oh, did anyone do something else? Others are getting different answers...
DeleteThat's what I did too! -Claire Westerlund
DeleteHi! I'm just finishing up the turn in and I'm confused on 5b. How is everyone approaching this problem when the maximum volume of air is unknown? -Claire Westerlund
ReplyDeleteI plugged 0 in for dv/dt to the equation I got in part a because at the maximum, the volume stops increasing. Then I solved the equation for t.
