The water level in a tank rises 4 feet every minute. Write an equation of change that describes the height H, in feet, of the water level at time t in minutes.a. dH/dt = 3b. dH/dt = 4c. dH/dt  = 5d. dH.dt = 6

The loudness, L, of a sound (measured in decibels, dB) is inversely proportional to the square of the distance, d, from the source of the sound. For a person 7 feet from a sound source, suppose the loudness is 85 decibels. How loud is the sound source when the person is 46 feet away?
