The distance, "d", to the horizon (= farthest point on the earth still visible) for an object that is "h" miles above the surface of the earth is given the formula d = the square root of 8000h +h^2. Determine how many miles above the surface of the earth is an orbiting satellite if the distance to the horizon is 900 miles.

just plug in your numbers and solve for h
900 = √(h^2+8000h)
h^2+8000h-900^2 = 0
h = 100
900 = √(h^2+8000h)
h^2+8000h-900^2 = 0
h = 100
