7. The rate at which pollution escapes a scrubbing process at a manufacturing plant in- creases over time as filters and other technologies become less effective. For this par- ticular example, assume that the rate of pollution (in tons per week) is given by the function r that is pictured in Figure 4.2.9. a. Use the graph to estimate the value of M. on the interval (0,4). tons/week b. What is the meaning of My in terms of the pollution discharged by the y= ) plant? c. Suppose that r(t) = 0.500.5. Use this formula for to compute Ls on 10,41 d. Determine an upper bound on the weeks total amount of pollution that can escape the plant during the pic. tured four week time period that is accurate within an error of at most one ton of pollution Figure 4.2.9: The rate, r(t), of pollution in tons per week -
