Question 831122: A cylindrical jar of radius 3cm contains water to depth of 5cm. The water is then poured at a steady rate into an inverted conical container with its axis vertical. After t seconds, the depth of water in this container is x cm and the volume, V ml, of water that has been transferred is given by V= 1/3 (pie)(x)(x)(x).
Given that all the water is transferred in 3 seconds,find
a) dv/dt in terms of pie
b) the rate at which c is increasing at the moment when x= 2.5

Question 832901: hi again i was wondering when your writing an equation in slope intercept form and your forming for the line through any two sets of coordinates….. when your done using slope intercept form; m=y2-y1/x2-x1 should you always use the first set of coordinates to replace the letters in the formula y=mx+b
sorry i know my question is a little confusing but when i did this for a math problem i had on HW i used the 2 set of coordinates and got it wrong then i used the 1 set of coordinates and got it right unless my math was just wrong , Thanks for your help

Question 835115: Marginal Revenue (MR)=$130
Total Cost (TC)=$1,100+135Q+0.6Q^2
Marginal Cost(MC)=135+1.2Q
P=MR=MC
Therefore, $130=135+1.2Q
$130-135=135-135+1.2Q
-5=1.2Q
-5/1.2=1.2Q/1.2
-4.17=Q
Did I do this correctly?
Thank you, -Amanda Thomas
