Modeling Using Variation · Exercise 62
Use the given information to answer the questions.
The intensity of light measured in foot-candles varies inversely with the square of the distance from the light source. Suppose the intensity of a light bulb is 0.08 foot-candles at a distance of 3 meters. Find the intensity level at 8 meters.
Its source prints no answer for this problem, so there's nothing to check against.
