Alright so here's what I did, I don't have an answer key so not sure if it's 100% right. 1) I rewrote r in terms of h as r/h = 10/12 so r = 5h/6 2) I substituted that in for r in the original and simplified getting a new equation of (25h^3 pi)/108. 3) I derived with respect to t and got...

I don't quite see how to do that, although it does look similar to something my teacher may of gone over in class. I'm thinking the similar triangles use radius and height as their legs, so the larger triangle I guess would be width of 5 and a height of 12 and the similar triangle would be a...

Homework Statement A conical tank (with vertex down) is 10 feet across the top and 12 feet deep. If water is flowing into the tank at a rate of 10 cubic feet per minute, find the rate of change of the depth of the water when the water is 8 feet deep. The Attempt at a Solution First I...

Thank you both for the help. :approve:

Alright so my reworked solution is as follows: Current of R1 = 1/2 Current of R2 so, Current of R1 = .25 A Current Through R3 = Current through R1 + R2 so, Current of R3 = .75 A Voltage through R2 = .5(8) = 4v Voltage through R3 = .75(20) = 15v Battery Voltage = 4v+15v = 19v V = IA...

Homework Statement In the figure, the current of the circuit in the 8 ohm resistor is 0.5 A. What is the current in the 2 ohm resistor? Figure http://img181.imageshack.us/img181/5576/helpfk7.jpg I'm trying to solve for the current in a complicated circuit. I'm given R1 = 16ohms, R2 =...
