The fish population of a lake is decreasing each year. A study is conducted. But, unfortunately some data was lost. The researcher found in her notes that in year one the fish population was 18000 fish and in year three the fish population was 8000 fish. Assume a constant rate of decay. Find a formula F

Step-by-step explanation:

The fish population after t years can be modeled by the following equation:

In which F(0) is the initial population and r is the constant rate of decay.

Year one the fish population was 18000

This means that

In year three the fish population was 8000 fish.

Two years later, so

So

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:
