A formula for calculating the magnitude of an earthquake is M = 2/3 log (E/E0) that uses the common (base 10) logarithm. This is called the Moment Magnitude Scale (MMS), an alternative to the more well known Richter Scale. One earthquake has magnitude 3.9 on the MMS. If a second earthquake has 800 times as much energy as the first, find the magnitude of the second quake. Round to the nearest hundredth. The magnitude of the second earthquake was
A small lake is stocked with a certain species of fish. The fish population is modeled by the function P = 14 / (1 + 4e^-0.9t), where P is the number of fish in thousands and t is the number of years since the lake was stocked. Find the fish population after 3 years. (Round your answer to the nearest whole fish). After how many years will the fish population reach 7000 fish? (Round your answer to two decimal places).
