Explain why (1/2) Integrate[x[t] y'[t] - y[t] x'[t], {t, a, b}] measures the area of R provided that {x[t], y[t]} sweeps out the boundary of R exactly one time in the counterclockwise fashion as t advances from a to b .

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function.a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
