Alvin, the original Human Occupied Vehicle (HOV), is on vacation. Since 1964, scientists have used Alvin for deep-sea exploration. Alvin is able to descend at a rate of 30 m/min to a maximum depth of 4500 m below sea level. As part of a plan to create an HOV that can dive deeper and stay underwater longer, Alvin is now undergoing many structural and systems upgrades. Source: Woods Hole Oceanographic Institute The equation that describes Alvin's depth D, in meters, is D = -30t, where t is the number of minutes Alvin has been descending. Graph this equation for 0 s t s 150.
