Suppose that in a certain biology lab experiment, the number of bacteria is related to the temperature T of the environment by the function N(T) = -27² + 2507 - 4900 (40 ≤ T ≤ 90). Here, N(T) represents the number of bacteria present when the temperature is 7 °F. Also, suppose that t hr after the experiment begins, the temperature is given by T(t) = 10t + 40 (0 ≤t≤ 5). (a) Compute N[T(t)]. N[T(t)] = (b) How many bacteria are present when t=0 hr? When t = 2 hr? When t = 5 hr? t = 0 hr bacteria bacteria t = 2 hr t = 5 hr bacteria
