Find the exponential growth function B. Predict the world population in 2014 C. When will the world population be 8.0 billion?Answer by stanbon(57361)   (Show Source): You can put this solution on YOUR website!In 2008,the world population was 6.7 billion and the exponential growth rate was 1.14% per year. A. Find the exponential growth function A(t) = 6.7 bil (1.14)^t where t is the number of years after 2008. ---------------------------------- B. Predict the world population in 2014 A(6) = 6.7 bil (1.14)^6 = 6.7 bil (2.1950) = 14.71 billion ------------------------- C. When will the world population be 8.0 billion 8 bil = 6.7 bil (1.14)^t --- 1.194 = 1.14^t --- Take the log: t*log(1.14) = log(1.194) t = 1.35 years ===================== Cheers, Stan H. =====================
