Population growth can often be modeled with an exponential function: Ratio: 5023 4936 1.0176 4 5111 5023 1.0175 ÷ 1.0176 1.0246 1.0175 World Population: 1986 4936 million 1987 5023 1988 5111 1989 5201 1990 5329 1991 5422 The world population in any year is about 1.018 times the previous year. in 2010: ( 29 19 5422 1.018 P = 7609.7 About 7.6 billion people. Nineteen years past 1991.
Radioactive decay can also be modeled with an exponential function: Suppose you start with 5 grams of a radioactive substance that has a half-life of 20 days. When will there be only one gram left? After 20 days: 1 5 5 2 2 = 40 days: 2 5 1 5 4 2 = t days: 20 1 5 2 t y = In Pre-Calc you solved this using logs. Today we are going to solve it graphically for practice.
