The magnitude of an earthquake, r, can be measured by the equation r=log(a/t)+d, where a is the amplitude in micrometers, t is measured in seconds, and d accounts for the weakening of the earthquake due to the distance from the epicenter. if an earthquake occurred for 4 seconds and d = 2, which graph would model the correct amount on the richter scale?
