The florida manatee population is 3,000 and is decreasing by 11% each year. Write a function for this situation.

stepan [7]

The required function of the situation is f(x) = 2670x.

Step-by-step explanation:

Given,

Population is = 3000

Evert year it is decreased by 11%.

To find the function of the given situation.

Formula

If the original population is a and is decreased by b% the population after 1 year will be a× $\frac{100-b}{100}$

After x year the population will be = a× $\frac{100-b}{100}$ ×x = $ax\frac{100-b}{100}$

Now,

Let after x years the population will be,

f(x) = 3000x× $\frac{100-11}{100}$

= 2670x

Hence,

The required function of the situation is f(x) = 2670x.

Licemer1 [7]

Answer:

$6 \frac{2}{5} \: miles$

Step-by-step explanation:

$First \: trail = 1 \frac{2}{5} = \frac{7}{5} \: miles \\ \\ second \: trail = 5 \times first \: trail \\ \\ = 5 \times \frac{7}{5} \\ \\ = 7 \: miles \\ \\ total \: length = \frac{7}{5} + 5 \\ \\ = \frac{7 + 25}{5} \\ \\ = \frac{32}{5} \\ \\ = 6 \frac{2}{5} \: miles$
