X Solve the problem. The rate at which an assembly line worker's efficiency E (expressed as a percent) changes with respect to time t is given by E'(t) = 80- 4t, where t is the number of hours since the worker's shift began. Assuming that E(1) = 88, find E(t). A E(t) = 80t - 4t2 + 10 B E(t) = 80t - 2t2 + 88 E(t) = 80t - 2t2 + 10 D E(t) = 80t - 2t2 + 166 E E(t) = 80t - 2t2-88
