Use the gures is calculate the left and right Riemann sums fer fen The given interval and the given value {if n. 3 f{x]=;+2 an [1.5]; n=4 The left Riemann sum for f is D. [Round ta two decimal places as needed.) The right Riemann sum for f is (Round to two decimal places as needed.)Use sigma notation to write the following Riemann sum. Then, evaluate the Riemann sum using formulas for the sums of powers of positive integers or a calculator. The right Riemann sum for f(x) = x + 2 on [0,8] with n = 40. The right Riemann sum is (Round to two decimal places as needed.)The velocity of an object moving along a line is given by v = 3t~ + 2 ft/s on the interval 0 Ets 4. a. Divide the interval [0, 4] into subintervals, [0, 1], [1, 2], [2, 3], and [3, 4]. On each subinterval, assume the object moves at a constant velocity equal to the value of v evaluated at the midpoint of the subinterval and use these approximations to estimate the displacement of the object on [0, 4].
