The rate decreased as time passed, and values of the rate at two-hour time intervals are shown in the table. t (h) 2 8 10 r(t) (L/h) 8.9 7.5 6.7 6.2 5.6 5.1 Find lower and upper estimates for the total amount of oil (in liters) that leaked from the tank over the interval [0, 10]. (Use five equal subintervals.) lower estimate 69.8 XL upper estimate 62.2 X L Enhanced Feedback Please try again. To estimate the volume of oil leaked during an interval of time, find an estimate for the area under the rate-of-leak graph using rectangles. Since the rate is decreasing during the interval, use right endpoints for an underestimate and left endpoints for an overestimate. Need Help? Read It Watch It Master It
