Answer to Question #134456 in Algebra for joseph se

Question

For this exercise, use the Richter scale equation M = log I/I0, where M is the magnitude of an earthquake, I is the intensity of the shock waves, and I0 is the measure of the intensity of a zero-level earthquake.

If an earthquake had an intensity of I = 5,011,872I0, find the Richter scale magnitude of the earthquake. Round to the nearest tenth.

Answer 1

M=log 5,011,872 I0/I0=log 5,011,872=6.7

Answer: M=6.7
