The relative volume of a sound is the logarithm of the intensity of the sound wave. In other words, V(x) = 10g10(1) where / is the intensity of the sound wave, measured in Watts per square-meter (W/m-), and the Relative Volume V (a ) is measured in decibels (dB). A. Find the change in Relative Volume when the Intensity of the sound wave increases from 10 W/m to 100 W/m2. Give proper units. B. Find the average rate of change of Relative Volume when the Intensity of the sound wave increases from 10 W/mto 100 W/m. Give proper units. C. Find the instantaneous rate of change in Relative Volume when the Intensity of the sound wave is 10 W/m . Give proper units. You may round your answer to 5 decimal places
