Answer:
Step-by-step explanation:
The magnitude, R of an earthquake is given by the equation: R=0.65log(0.39E) +1.45
Where
where E is the energy (measured in kilowatt-hours) released by the earthquake.
1) The amount of energy released by an earthquake of magnitude 7.5 would be
7.5 = 0.65log(0.39E) + 1.45
(7.5 - 1.45)/0.65 = log(0.39E)
9.3077 = log(0.39E)
0.39E = 10^9.3077
E = 10^9.3077/0.39 = 5207573316 kilowatt-hours
b) the attached diagram shows the steps used to find the quotient and the remainder using synthetic division.
