Solve the problem.
-The Richter Scale measures the magnitude M of an earthquake. An earthquake whose seismographic reading measures x millimeters 100 kilometers from the epicenter has magnitude M given byven by $M ( x ) = \log \left( \frac { x } { 10 ^ { - 3 } } \right)$ . Give Giv

From its epicenter. Round to the nearest tenth.
A)9.0
B)2.0
C)7.0
D)8.0

Question

Quizplus · Accepted Answer

The magnitude M is calculated as $ M = \log \left( \frac{99236}{10^{-3}} \right) = \log(99236000) $. Calculating this gives approximately 8.0.

Solve the Problem M(x)=log⁡(x10−3)M ( x ) = \log \left( \frac { x } { 10 ^ { - 3 } } \right)M(x)=log(10−3x​)

Solve the Problem $M ( x ) = \log \left( \frac { x } { 10 ^ { - 3 } } \right)$
