The fish population of a lake is decreasing each year. A study is conducted. But, unfortunately some data was lost. The research
Solnce55 [7]

Answer:

F(t) = 18000(0.6666)^{t}

Step-by-step explanation:

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

F(t) = F(0)(1-r)^{t}

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 F(0) = 18000

In year three the fish population was 8000 fish.

Two years later, so F(2) = 8000

F(t) = F(0)(1-r)^{t}

8000 = 18000(1-r)^{2}

(1-r)^{2} = 0.4444

\sqrt{(1-r)^{2}} = \sqrt{0.4444}

1 - r = 0.6666

r = 0.3334

So

F(t) = 18000(0.6666)^{t}

Hi please help me really need it!
adelina 88 [10]

Answer:

C

Step-by-step explanation:

To Solve, just cube the terms on the right side to see if they go back to the number on the left.

The first part is true because multiplying 11 * 11 * 11 = 1331.

The second part is true because multiplying 5 * 5* 5 = 125.

The third part is false because multiplying 8 * 8 * 8 = 512.

The fourth part is true because multiplying 1 * 1* 1 = 1.
