Question
The table shows the populations (in millions) of five countries in 2013 and the projected populations (in millions) for 2025.
| Country | 2013 | 2025 |
|---|---|---|
| Australia | 22.3 | 25.1 |
| Canada | 34.6 | 37.6 |
| Hungary | 9.9 | 9.6 |
| Philippines | 105.7 | 128.9 |
| Turkey | 80.7 | 90.5 |
(a) Find the exponential growth or decay model,
y = aebt or y = ae−bt,
for the population of each country, where t is the year, with
t = 13
corresponding to 2013. Use the model to predict the population of each country in 2045. (Round the exponential coefficient b to four decimal places. Round all other values to one decimal place.) | Australia population model | y = |
