Question 175492: Here is a two part question:
Did you know that the weight of an object on earth also varies according to the eleveation of the object? In particular, the weight of an object follows this equation: w=Cr^-2, where C is a constant, and r is the distance that the object is from the center of the earth.
a. Solve the equation w=Cr^-2 for r.
b. Suppose that the object is 100 pounds when it is at sea level. Find the value of C that makes the equation true. (Sea level is 3,963 miles from the center of the earth.)
I have no idea how to start with part a. PLease help.

Question 175500: Okay, I understand the answer to the first part, r=square root of c/w.
I think for the next part (Suppose that the object is 100 pounds when it is at sea level. Find the value of C that makes the equation true. (Sea level is 3,963 miles from the center of the earth.)
the problem would be written
100=C(square root of c/w)
Sorry for the written out problems. Cant find the right buttons on the keyboard. I am really struggling with algebra in general, but the radicals have me in a loop. I appreciate all of the help.
