Assuming that the world population follows an exponential growth model, find the projected world population in 1995. 2.) M = log (Intensity/Fixed-Intensity) The 1906 San Francisco earthquake had a magnitude of 8.3 on the Richter scale. Suppose that at the same time in South America there was an earthquake with magnitude 3.9 that caused only minor damage. How many times more intense was the San Francisco earthquake than the South American one?

• ### Is it reasonable to drop a class in my senior year of high school?

Hello, I am currently suffering from a C in AP Calculus and my grades in English and Physics are somewhat dropping along. I was thinking about being removed from the highest level of dance at my school to concentrate more on math. Will it effect my acceptance rate to a UC? It's not an honors course.
