Math MATHEMATICS A PRACTICAL ODYSSEY W/ACCESS

In 1969, the National Academy of Sciences published a study titled "Resources and Man." That study places "the earth's ultimate carrying capacity at about 30 billion people, at a level of chronic near-starvation for the great majority (and with massive immigration to the now less-densely populated lands)!" The study goes on to state that 10 billion people is "close to (if not above) the maximum that an intensively managed world might hope to support with some degree of comfort and individual choice." The world population in 1990 was 5.283 billion; in 2000, it was 6.082 billion. a. Develop the mathematical model that represents world population. b. Use the model to predict when world population would reach the "somewhat comfortable" level of 10 billion. c. Use the model to predict when world population would reach "the earth's ultimate carrying capacity" of 30 billion.
