Final answer:
To calculate the number of squirrels after t years, you can use the function N(t) = N0 * (1 + r)^t, where N0 is the initial population, r is the annual growth rate, and t is the number of years.
Step-by-step explanation:
To find the function to show how many squirrels there will be after t years, we can use the formula:
N(t) = N0 * (1 + r)t
Where:
- N(t) is the number of squirrels after t years
- N0 is the initial population of squirrels
- r is the annual growth rate expressed as a decimal
- t is the number of years
In this case, the initial population is 9 squirrels and the annual growth rate is 2.5%, which is equivalent to 0.025 as a decimal. Therefore, the function would be:
N(t) = 9 * (1 + 0.025)t
