Casey Wilson · Answer 1

P (t) = 800-x (t)

Step-by-step explanation:

Assuming that no other pine tree naturally grows

Let the number of pine trees killed every year be x

Remaining trees after 1 year will be 800-x

After two years, remaining trees will be 800-2x

After three years, remaining trees will be 800-3x

The trend here is

P (t) = 800-x (t) hence after 5 years

P (5) = 800-5t and so on

Therefore, the function is

P (t) = 800-x (t)
