A particular type of bacteria is found to be capable of doubling in number about every 48.5 minutes. The number N of bacteria present after t minutes could be modeled by N(t) = Noe 0.014. Suppose that No =500,000 is the initial number of bacteria per milliliter. Complete parts (a) and (b) below. (a) Approximate the number of bacteria per milliliter after 4 hours. After 4 hours, there are approximately bacteria per milliliter. (Round to the nearest thousand as needed.)
