(Round your answers to two decimal places.) (a) If the world population oontinues to grow at approximately 2%/year, find the length of time t, required for the population to quadruple in sıze. yr (b) Using the time to found in part (a), what would be the world population if the growth rate were reduced to 1.4%/yr? billion people Need Help?
