Mathematics Homework Help. pls solve my precalculus word problem. ASAP. Use steps below to solve.
The Richter scale is used to measure the magnitude of a earthquake. The magnitude, R, is given by the equaiton R=0.65log(0.39E)+1.45, where E is the energy (measured in kilowat hours)released by the earthquake. Determine the amount of energy released by an earthquake of magnitdude 7.5
USE THESE STEPS TO SOLVE:
a. Rewrite equation for magnitude of earthquake, using magnitude of 7.5 given in problem.
b. Simplify so it is writen in form b=loga
c.solve problem for E, the energy released in earthquake.
