- In an electronic device, individual circuits may serve many purposes. In some cases, the flow of electricity must be con- trolled by reducing the power instead of amplifying it. In the circuit shown here, a voltage V volts and resistance R ohms are given. We want to determine the size of the remaining resistor (x ohms). The power absorbed by the circuit is V²x p(x)= (R+x)² ' Find the value of x that maximizes the power absorbed. R

Hello, I was stuck on this one Optimization problem for Calculus A. The question is: A water tank is in the form of a triangular prism. The bottom is an equilateral triangle and the top is open. The volume of the tank must be 1000sqrt3 cubic inches. What is the minimum surface area of the tank? [Note: The Area of an equilateral triangle with a side length of x, is x2sqrt3/4] Thanks
