According to the State Department of Finance, California’s population was
Calculate the percent increase from 1998 to 1999 and the percent increase from 1999 to 2000. Does this suggest exponential population growth?
Calculate this value with the two different data sets. Are they nearly the same?
Assuming exponential population growth, write an equation to model this data.
Let the year 1998 correspond with. Use your model to predict California’s population in 2020 assuming your model remains valid.
Evaluate
. The increase in population is proportional to the current population. In other words, if the population is growing
each year and the current population is people, the increase is people. If the current population is people, the increase is people. According to your model, by approximately how many people did California’s population increase in the year 2000? Answers will vary depending on the rate estimate.
Explain why the increase in population is proportional to the current population. What is the constant of proportionality?
Find growth factor in part (a).
