Help with #1(a and b)

calculator only on the indicated problems. 1) The rate at which water flows out of a pipe, in gallons per hour, is given by a differentiable function R of time t. The table below shows the rate as measured every 3 hours for a 24-hour period. a.) Use a midpoint Riemann sum with 4 subdivisions of equal length to R(1) approximate R(t) di . You must simplify your answer. hours gallons per hour 4.5 5.5 5.8 6 12 6.4 15 6.5 5.7 5 24 4.5 b.) Use a right Riemann sum with 8 subdivisions of equal length to approximate [R(t) dt . You do not need to simplify your answer. 2) Let y(t) represent the rate of change of the population of a town over a 20-year period, where y is a
