Doing some online classes and confused about many problems, I'd like to see if my answer is correct. Here's the problem:
Can someone give me the answer, show the work, and explain how you got it? Thanks.For the following direct variation, give an equation that relates the two variables and includes a variation constant.
The kinetic energy (KE) of a 1 kg mass is directly proportional to the square of the speed (v). Variation constant = 1/2.
This ones more confusing:
Suppose that w varies directly as z2 and inversely as xy. When w = 10, x = 15, y = 2, and z = 5. Find z when w = 2, x = 8, and y = 27.
