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

True [87]

Answer:

$P=3000(0.89)^t$

Step-by-step explanation:

It was given that, florida manatee population is 3,000 and is decreasing by 11% each year.

We want to write a function for this situation.

Since the population is decreasing annually, it is modelled by:

$P=P_0(1-r\%)^t$

We substitute the give initial population and rate of decrease to get:

$P=3000(1-0.11)^t$

This simplifies to:

$P=3000(0.89)^t$

What is the value of a over 6 plus 3 if a=48

AlexFokin [52]

Hello there!

By a over 6, I assume you mean a / 6? And by the wording, I assume 3 is outside of the fraction.

For the three outside the fraction,

(a / 6) + 3
(48 / 6) + 3
8 + 3
= 11

What is the expression for the area of the old garden if the perimeter is 6w+8, where W represents the width?

musickatia [10]

Answer:

w(2w+4)

Step-by-step explanation:

we know A = l * w

and Perimeter = 2l + 2w

we want to find l in terms of w

2l + 2w = 6w + 8

2l = 4w + 8
