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.

Question 175540: Here is another application I am struggling with. I submitted it earlier but my computer shut down and I am unsure if it went through or not. Here it is again.
2. The equation [D=1.2 square root of h] gives the distance, D, in miles that a person can see to the horizon from a height, h, in feet.
a. Solve this equation for h.
b. Long’s Peak in the Rocky Mountain National Park, is 14,255 feet in elevation. How far can you see to the horizon from the top of Long’s Peak? Can you see Cheyenne, Wyoming (about 89 miles away)?
