When satellites observe Earth, they can scan only part of Earth's surface. Some satellites have sensors that can measure the angle shown in the figure. Let h represent the satellite's distance from Earth's surface and let r represent Earth's radius. Find the rate at which h is changing with respect to when (Assume r = 4460 miles.) Round your answer to the nearest unit.
A) -2973 mi/radian
B) -5150 mi/radian
C) 5150 mi/radian
D) -8920 mi/radian
E) 2973 mi/radian
