1) The magnitude M (moment magnitude) of an earthquake is represented by the equation M = log () where 104.4 joules is the assigned minimum E is the amount of energy released by the earthquake in joules and Eo measured released by an earthquake. What is the magnitude of an earthquake that released 1.4 · 1013 joules of %3D energy? Round to 2 decimal places. 2) The population of a small town is modeled by the equation y = 1650e0.5t where t is measured in years. a) In approximately how many years will the town's population reach 20,000? Round to the tenth of a year. b) What is the doubling time for the population? Round to 3 decimal places.
