Assume that the population continues to grow at the rate of approximately 2%/year and find the function Q(t) that expresses the world population (in billions) as a function of time t (in years), with t = 0 corresponding to the beginning of 1990. (Round your answers to two decimal places.)

(a) If the world population continues to grow at approximately 2%/year, find the length of time t0 required for the population to quadruple in size.
t0 =  70

(b) Using the time t0 found in part (a), what would be the world population if the growth rate were reduced to 1.9%/yr?
