A. The human population of the earth is currently increasing by about 1.1% per year. If it continues at this rate, how many years will it take for the population to double? If the current population is 7 billion people, in how many years will the population reach 56 billion people? B. The population of Steller sea lions is decreasing at a rate of about 5% per year. If it continues at this rate, how many years will it take for the population to decline by one- half? If the current population is 40,000, in how many years will the population reach 10,000 Steller sea lions? C. Verify that pn = -n-1 is a particular solution of: Xn+1 = 3xn + 2n + 1.
