Transcribed Image Text:On April 25, 2015, an earthquake of magnitude 7.8 on the Richter scale struck Nepal. On May 12, 2015, a major aftershock of magnitude 7.3 on the Richter scale shook the same region. (Round your
answers to two decimal places.)
(a) How did the power of the first earthquake and this aftershock compare?

Transcribed Image Text:The gross tonnage G is a standardized measure of a ship's capacity. It is calculated in terms of the volume V, in cubic meters, of the ship. There are no units associated with gross tonnage. It is
calculated using the formula
G = V(0.2 +0.02 log V).
In this exercise, round your answers to the nearest whole number.
(a) Find the gross tonnage of a ship with a volume of 15,000 cubic meters.
2659
X
(b) Use the crossing-graphs method to find the volume of a ship with a gross tonnage of 8000.
