: 1 Point The Magnitude M Of An Earthquake Is Calculated According To M A 4 Log A Where A Is The Amplitude Of The 2 (42.39 KiB) Viewed 34 times

(1 point) The magnitude M of an earthquake is calculated according to M(A) = 4 + log(A), where A is the amplitude of the earthquake in cm. The 2011 tsunami and ensuing nuclear disaster in Eastern Japan was the result of an earthquake with a magnitude of 9.1. What was amplitude of the earthquake? 4.9590 cm

(1 point) Dr. Ligo and his friend David visited Glacier National Park. David defeated a grizzly bear in hand- to-hand combat and sustained several minor injuries. If we let A represent the area of the contusion on David's forearm (in cm?), A is given after t days by the formula A(t) = 15(1 – 0.04). How long will it take for David's wound to decrease to an area of 4 cm?? 13.824 days
