Write a power function for the following situation, and then use the equation to solve for the missing information. The intensity **I** of light varies inversely as the square of the distance **D** from the source. If the intensity of illumination on a screen 5 feet from a light is 2 foot-candles, find the intensity of illumination on a screen 5 feet from the light.
