In all problems involving days, a 365-day year is assumed.
World population growth. It took from the dawn of humanity to 1830 for the. population to grow to the first billion people, just 100 more years (by 1930) for the second billion, and 3 billion more were added in only 60 more years (by 1990). In 2006, the estimated world population was 6.5 billion with a relative growth rate of 1.14%.
(A) Write an equation that models the world population growth, letting 2006 be year 0.
(B) Based on the model, what is the expected world population (to the nearest hundred trillion) in 2015? In 2030?
(C) Sketch a graph of the equation found in part (A). Cover the years from 2006 through 2030.
