A biology class at Central High School predicted that a local population of animals will double in size every 12 years. The population at the beginning of 2014 was estimated to be 50 animals. If P represents the population n years after 2014, then which of the following equations represents the class’s model of the population over time?A) P=12+50nB) P=50+12nC) P=50(2)12nD) P=50(2)12n
Q. A biology class at Central High School predicted that a local population of animals will double in size every 12 years. The population at the beginning of 2014 was estimated to be 50 animals. If P represents the population n years after 2014, then which of the following equations represents the class’s model of the population over time?A) P=12+50nB) P=50+12nC) P=50(2)12nD) P=50(2)12n
Identify Population and Growth Rate: Identify the initial population and the growth rate.Initial population a = 50.The population doubles every 12 years, so the growth factor b is 2 every 12 years.
Convert to Annual Growth Factor: Convert the growth rate to an annual growth factor.Since the population doubles every 12 years, the annual growth factor is 21/12.
Write Exponential Growth Equation: Write the exponential growth equation.The population P after n years from 2014 can be modeled by P=50(2n/12).
