Suppose that d is the distance, IN MILES, on the surface of the Earth that can be seen from the satellite. NOTE: The radius of Earth is 3960 miles. (a) If d is to be 2500 miles, how high must the satellite orbit above Earth? (b) If the satellite orbits at a height of 300 miles, what distance d on the surface can be seen?
