Exponential and Logarithmic Functions HELP PLS

1) c) y = 500 * 2^x
In year 1, x = 1 and the population is 500 * 2^1 = 1000
In year 2, this doubles to 500 * 2^2 = 500 * 4 = 2000
ans so on
This model describes the population doubling every year

2)
A) 3 (1/2)^x and C) (0.25)^x
These numbers reduce as x increases because there is a number with an absolute value less than 1 is being raised to the power of x. They also will never totally reach zero or become negative, but will approach zero as x becomes very large.

The length of a rectangle is (x - 9) feet. Its width is x feet. Write an expression you could use to find the perimeter

steposvetlana [31]

Answer:

The expression for the perimeter of the rectangle is: $P = 4x - 18$

Step-by-step explanation:

Perimeter of a rectangle:

A rectangle has length l and width w. It's perimeter is given by:

$P = 2(l + w)$

In this question:

$l = x - 9, w = x$

So

$P = 2(x - 9 + x) = 2(2x - 9) = 4x - 18$

The expression for the perimeter of the rectangle is: $P = 4x - 18$
