The speed of a particle in a test laboratory was noted every second for 3 seconds. The results are shown in the following table. Use the left endpoints and then the right endpoints to estimate the total distance the particle moved in the first three seconds. t (sec) 1 2 3 v (ft/sec) 9 7.5 5.5 The estimate of the total distance the particle moved in the first three seconds using left endpoints is ft. The estimate of the total distance the particle moved in the first three seconds using right endpoints is ft.Calculate the definite integral by referring to the figure with the indicated areas. Ay Area A = 1.488 Area C = 5.549 Area B = 2.316 Area D = 1.766 A b d X B :D . . . . . b\fUse the definite integral to find the area between the x-axis and f(x) over the indicated interval. Check first to see if the graph crosses the x-axis in the given interval. f(x) = 16-x2; [- 1,9] . . . . . The area between the x-axis and f(x) is. (Simplify your answer. Type an integer or an improper fraction.)
