A colony of bacteria has a total weight which varies according to w(t)= 12.5e0.5t (weight in Newtons, time in hours). Find the average weight of the colony over the interval [1, 5]. (Round your answer to two decimal places.) 47.84 XN Find a value c in [1, 5] such that w(c) attains this average. (Round your answer to two decimal places.)
