The volume of a rectangular box is 330 cubic inches. The length on one side of the top is 11 inches, and the height of the box i

Fiesta28 [93]

Answer: 110 square inches.

Step-by-step explanation:

The volume of a rectangular box would be:

$V=length*width*height$

In this case, we know the volume, the length and the height, and we don't know the width, so we're going to isolate it:

$width=\frac{V}{length*height}$

Substituting the data:

$width=\frac{330}{11*3} =10in$

This width is also the width of the top of the box, so the area of the top would be:

$A=length*width\\A=11*10\\A=110in^{2}$

Find the domain of the rational expression: x-4/2x-6

marin [14]

Answer:

All real numbers except 3

Step-by-step explanation:

Given

$\frac{x - 4}{2x - 6}$

Required

Determine the domain

We start by writing the following inequality

$2x - 6 \neq 0$

Add 6 to both sides

$2x -6 + 6 \neq = 0 + 6$

$2x \neq 6$

Divide both sides by 2

$\frac{2x}{2}\neq \frac{6}{2}$

$x \neq \frac{6}{2}$

$x \neq = 3$

As such, the domain of x is all real numbers except 3

What the domain and range is for the function f(x) = x2 + 4x - 21.

prisoha [69]

Answer:

Step-by-step explanation:

Please use " ^ " to denote exponentiation: f(x) = x^2 + 4x - 21.

This function has a graph which is a parabola that opens up.

Its vertex is found by completing the square:

x² + 4x + 4 - 4 - 21, or

(x + 2)² - 25

Comparing this to the standard equation

(x - h)² + k, we see that h = -2 and k = -25.

Thus, the vertex (and the minimum of this function) is (-2, -25).

Thus, the range is [-25, ∞ ). This being a polynomial function, it has no restrictions on the domain: the domain is (-∞, ∞ )
