Solve the problem. An efficiency study of the morning shift at a factory (7:00 A.M. to 12:00 noon) indicates that an average worker who arrives on the job at 7:00 A.M. will have produced Q units t hours later, where Q(t) = -+3 + 6+2 + 15t When during the morning shift does the worker's production reach the point of diminishing returns? Ot = NIU (9:30 A.M.) O t = 2 (9:00 A.M.) = N / W (8:30 A.M.) O t = 3 (10:00 A.M.)Solve the problem. Let p = (9 - 2x) for 0
