Bird Population The population of a certain species of bird is limited by the type of habitat required for nesting. The population behaves according to the logistic growth model
where t is measured in years.
(a) Find the initial bird population.
(b) Draw a graph of the function
(c) What size does the population approach as time goes on?

- The table shows the mid-year populations (in millions) of five countries in 2015 and the projected populations (in millions) for the year 2025. (a) Find the exponential growth or decay model y=aebt or y=aebt for the population of each country by letting t=15 correspond to 2015. Use the model to predict the population of each country in 2035. (b) You can see that the populations of the United States and the United Kingdom are growing at different rates. What constant in the equation y=aebt gives the growth rate? Discuss the relationship between the different growth rates and the magnitude of the constant.arrow_forwardPopulation The table shows the mid-year populations (in millions) of five countries in 2015 and the projected populations (in millions) for the year 2025.
