Answer:

910$

Step-by-step explanation:

It's easiest if we just add the width and length together to start which would be 2 sides of the fence so we multiply by 2 to complete the whole perimeter.

80+60 = 140 x 2 = 280

Now you need to multiply 280 by 3.25 because that is what it will cost in the end since the 280 is all of the feet together and the 3.25 is each foot's price.

3.25 x 280 = 910

Answer:

A) The functions are not inverses of each other.

Step-by-step explanation:

$f(g(x))=\sqrt{(x^2+3)-3}=\sqrt{x^2}=|x|\ne x$

The result of f(g(x)) is not always x, so the functions are not inverses of each other.

In general, a quadratic (or any even-degree polynomial) such as g(x) cannot have an inverse function because it does not pass the horizontal line test.
