Oil is being pumped out of the tank at a rate R(t ), where R (t) is measured in gallons per hour, and t is measured in hours. The table below shows selected values for R(t). Using a trapezoidal approximation with three subintervals and the data from the table, find an estimate of the number of gallons of oil that are in the tank at time t = 14 hours. t (hours) 2 5 10 14 R(t) gallons per hour 8.2 7.8 8.6 9.3 A. 220.8 B. 19.2 D. 18.75 C. 100.8Free Response acb Sfoodx = - Steady a b Let f be the continuous function defined on [-6, 6] whose graph consists of a quarter circle and three line segments, as shown above.
