Answer:

see below

Step-by-step explanation:

f(x) = –(x + 6)(x + 2)

The function is increasing until it reaches the vertex, so it will increase until x=-4.  The function will decrease after the vertex, so after x = -4

increasing: -∞ < x < -4

decreasing : -4 < x < ∞

Find the volume of a rectangular prism with the width of x-1, a length of x+1 and a height of 2x-3.
Damm [24]

Answer:

The Volume is equal to 2x^3-3x^2+2x-3

Step-by-step explanation:

Formula for the volume of a rectangular prism is V=WHL

We know that:

W=x-1

L=x+1

H=2x-3

So, V= (x-1)(x-1)(2x-3)

Simplify

(x^2+1)(2x-3)

2x^3-3x^2+2x-3

Dovator [93]
<span>Given that there are 50 campers at day camp and 10 counselors.

The ratio of campers to counselors as a fraction is given by \frac{50}{10}.

Using equivalent fractions we have \frac{50\div10}{10\div10} = \frac{5}{1}.

Thus, the related rate and unit rate to the ratio of campers to counselors is given by \frac{5}{1}.

The unit rate indicates that for every counselor, there are 5 campers.</span>
