Please help! Sound intensity, I, from a spherical source is a function of the distance, r, from the source of the sound. It is represented by the function I= P/4pir^2 where P is the power of the sound. Explain the behavior of the graph of I and what it means in context.

For this item, we can see that r, the distance from the source of the sound, is in denominator and squared then, this means that the sound intensity is inversely proportional to the square of the distance. The increase in distance will decrease the intensity and it will increase if the distance is decreased.
