Intensity of light varies directly with inverse of the square of
the distance from the light source.
At a distance of 25 ft. from a certain light source, the intensity
of the light is measured as 40 candles.
Find a funciton to express I(x), light intensity I as a function of
distance x.
What is the intensity at 45 ft.?
What should the distance be to produce an intensity of 100
candles?
