Approximate the area under the curve y = :32 from :3 = i] to m = 2 using a Right Endpoint approximation with 4 subdivisions. Liquid leaked from a damaged tank at a rate of t) liters per hour. The rate decreased as time passed and values of the rate at threehour time intervals are shown in the table. t {hr} r(t] {Uh} 0 10.6 3 10.1 6 9.? 9 9.2 12 8.8 15 8.4 Find lower and upper estimates for the total amount of liquid that leaked out. lower estimate = liters upper estimate = - liters Evaluate the integral below by interpreting it in terms of areas in the figure. The areas of the labeled regions are 10 A1: 3, A2=3, A3=1 and A4=1 {gure is NOT to scale] V = jollmm The amount of trash, in tons per year, produced by a town has been growing linearly, and is projected to continue growing according to the formula P(t) = 60 + 5t. Estimate the total trash that will be produced over the next 10 years by interpreting the integral as an area under the curve. tons
