Question 55284: I WOULD REALLY APPRECIATE IF IT SOMEONE HELPED ME WITH THIS PROBLEM:
The decibel level of sound is given by D=10 LOG(I/10^-12), where I is the sound intensity measured in watts per square meter. Find the decibel level of a whisper at an intensity of 5.4*10^-10 watts per square meter.

You can put this solution on YOUR website!
D=10 LOG(I/10^-12), where I is the sound intensity measured in watts per square meter. Find the decibel level of a whisper at an intensity of 5.4*10^-10 watts per square meter.
---------
D=10 log [(5.4X10^-10)/(10^-12)]
D=10 log [5.4X10^2)]
D=10 [log [5.4) + 2]
D=10 [2.73239...]
D=27.3239
