solve the equation (for r)w=cr and the squre is -2

I don't understand the equation or i'd help u.

1. Many people know that the weight of an object varies on different planets, but did you know that the weight of an object on earth also varies according to the elevation of the object? In particular, the weight of an object follows this equation: , where C is a constant, and r is the distance that the object is from the center of the earth.

a. Solve the equation for r.

b. Suppose that an 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.)

c. Use the value of C you found in the previous question to determine how much the object would weigh in

i. Death Valley (282 feet below sea level)

ii. The top of Mt McKinley (20,320 feet above sea level)

To solve the equation w = cr for r, we need to isolate the variable r on one side of the equation. Here are the steps to do that:

Step 1: Start with the equation w = cr.
Step 2: Divide both sides of the equation by c to isolate r.
(w / c) = (cr / c)
This simplifies to: (w / c) = r
Step 3: Therefore, the equation can be rewritten as r = (w / c).

Now, let's address the note about the square being -2. It seems there might be some confusion there. In the equation w = cr, there is no mention of a square or the value -2. However, if there is additional information or context related to the equation, please provide more details so I can assist you accordingly.
