Hello! I just need the answer for part C Thank you

The Richter scale provides a measure of the magnitude of an earthquake. The following formula shows a relationship between the amount of energy released and the Richter number. 

\( M = \frac { 2 } { 3 } \log \frac { E } { 0.007 } \) 

where \( E \) is measured in kilowatt-hours. a. What value of E gives a Richter number \( M = 8.2 \) ? \( 1.397 ( 10 \) . (Use scientific notation. Use the multiplication symbol in the math palette as needed. Round to three decimal places as needed.) b. If a particular household uses \( 248 \) kWh per month, how many months would the energy released by an earthquake of this magnitude power \( 10 \) million households? 

\( 5.6 \) (Round to one decimal place as needed.) c. Find the rate of change of the Richter number \( M \) with respect to energy when \( E = 60,000 kWh \) . (Round to seven decimal places as needed.)
