Explanation:
(a) To find a function that models the fox population t years after 2000, we can use the formula for exponential growth:
P(t) = P0 * (1 + r)^t
where P0 is the initial population, r is the annual growth rate, and t is the number of years after the initial population.
Plugging in the given values, we get:
P(t) = 23600 * (1 + 0.07)^t
Therefore, the function that models the fox population t years after 2000 is:
P(t) = 23600 * 1.07^t
(b) To estimate the fox population in the year 2008, we need to find the value of P(t) when t = 8 (since 2008 is 8 years after 2000). Plugging in t = 8 into the function from part (a), we get:
P(8) = 23600 * 1.07^8
P(8) ≈ 41333
Therefore, the estimated fox population in the year 2008 is 41,333 (rounded to the nearest integer).
