O 11 7 O O 11 O -JH O -J CQuestion 2 1 pts Let R be the region bounded by the curves 3:: cosm+sin1t+L m=n';'2. 1::srf2. and the x- axis. Round all answers to two decimal places. {3] Approximate the area of R using left-endpoints and 4 rectangles of equal width. ' [Select] V' [b] Approximate the area of R using right-endpoints and 4 rectangles of equal width. ' [Select] V' [1:] Approximate the area of R using midpoints and 4 rectangles of equal width. ' [Select] V' Question 3 1 pts For this question, make sure you recall the difference between displacement and distance travelled of a moving object. A bird flies along a straight line while its velocity is monitored. The following data is collected: Time (in hours) Velocity (in km/h) O 30 0.5 45 1 45 1.5 50 2 30 2.5 -20 3 -25 3.5 -10 4 52.5 -20 3 -25 3.5 -10 4 5 Answer the following questions with integer numbers. Do not enter units! (a) Approximate the displacement of the bird (in km) during 0
