Chapter 4.6, Problem 2E

Change the function y=3(0.5)x to one having e as the base.

Find the unknown value. y varies inversely as the square of x and when x=3,y=2. Find y if x=1.

Find the unknown value. 27. y varies jointly with x and the cube root of 2. If when x=2 and z=27,y=12, find y if x=5 and z=8.
