D Question 8 10 pts 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) = 50-4t, where t is the number of hours since the worker's shift began. Assuming that E(1) - 88, what is E(t)? O E(1) = 50t - 212 + 136 O E(t) = 50t - 412 + 40 O E(1) = 50t - 212 + 88 O E(t) = 501 - 212 + 40
