Question 1089545: Write an equation that expresses the relationship. Use k as the constant of variation.
The weight of a body above the surface of the earth is inversely proportional to the square of its distance from the center of the earth. What is the effect on the weight when the distance is multiplied by 7?

w, weight
d, distance from center
k, variation constant

w=k%2F%28d%5E2%29

What is the effect on the weight when the distance is multiplied by 7?
-------------------------------------------------------------------------

w=k%2F%28%287d%29%5E2%29

w=k%2F%2849d%5E2%29
or
w=%28k%2F49%29%281%2Fd%5E2%29
