ITEMS INFO Practice similar Next > In this problem, use the general expressions for left and right sums, left-hand sum = f(to) At + f(t1) At + . . . + f(tn-1)At and right-hand sum = f(t1) At + f(t2) At + . . . + f(tn) At, and the following table: + 0 3 6 9 12 f(t) 25 22 20 19 18 A. If we use n = 4 subdivisions, fill in the values: At = to = ;t1 = ; t2 = ; t3 = tA = f(to) = ; f (t1 ) = ; f ( t2 ) = ; f (t3) = ; f(t4) =B. Find the left and right sums using n = 4 left sum = right sum = C. If we use n = 2 subdivisions, fill in the values: At = to = ; t1 = = f (to) = ; f ( t1 ) = ; f (t2) = D. Find the left and right sums using n = 2 left sum = right sum =2. Practice similar Your task is to estimate how far an object traveled during the time interval 0
