Liquid leaked from a damaged tank at a rate of r(t) liters per hour. The rate decreased as time passed and values of the rate at three-hour time intervals are shown in the table. rm (L/h) 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 A1= 6, A2=4, A3=2 and A4=2 (ligure is NOT to scale) 7 v=f3 (2+f(m))dm V: Enter your answer as a whole number
