Solve for the indicated value, and graph the situation showing the solution point. The formula for
measuring sound intensity in decibels D is defined by the equation D = 10log (+) using the
common (base 10) logarithm where I is the intensity of the sound in watts per square meter and
Io = 10-12 is the lowest level of sound that the average person can hear. How many decibels are
emitted from a jet plane with a sound intensity of 8.9 · 102 watts per square meter?
Round your answer to three decimal places.
The jet plane emits
