the world population in 2ooo was approximately 6.08 billion. the annual rate of increase was about 1.26%. find the world population in 2016

Answer 1

Assume t = 0 in the year 2000. Population is modeled using P(t) = (Pinitial)(1+growth rate)^t. Pinitial = 6.08 billion, so the equation becomes P(t) = 6.08*10^9(1.0126)^t. Plugging in t = 16 (16 years since 2000), we get P(16) = 6.08*10^9(1.0126)^16 which equals 7,428,657,714 (7.4 billion)
