Math Problem Statement

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(I/I[0]) using the common (base 10) logarithm. where I is intensity of the sound in watts per square meter and I[0]=1-^-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 in tensity of 8.5*10^2 watts per square meter?

round answer to three decimal places.
