Extracted text: The rate of infections with respect to time t (measured in days) within a population is seen to be rising exponentially according to the relation: I = e(k–1)t (Infections per day) This occurs over a period of 20 days from time t = [0, 20], where k = 1.4. a) What is the period of time t required for the initial infection rate I(t = 0) to double in number? State answer to within 3 decimal places.
