Hi there!

Lets dive into the problem, starting with the equation for volume; length x width x height.

If it's 8 x 12 inches, That means the height is 8 and the length is 12. The side, or width, would be x.

The equation should be 8 times 12 times x, or (8)(12)(x).

What is true of the function g(x)=-2x^2+5?

mart [117]

Answer:

C) The variable x represents the independent variable.

Step-by-step explanation:

The given function is $g(x)=-2x^2+5$ .

g(x) is NOT the multiplication of g and x because g is a function of x.

$x$ is the input of the function.

$-2x^2+5$ is the output of the function.

The variable $x$ is called the independent variable because we plug in values of x to find g.

The variable g represents the output of the function NOT the input.

The correct choice is C

Can someone solve this?

Gemiola [76]

Answer:

B : $4x\sqrt{17}$

Step-by-step explanation:

If you divide a rhombus using its diagonals, you get 4 right triangles, whose legs are both 1/2 the length of the diagonals.

This means that the legs of one of those 4 triangles have lengths of 2x/2, and 8x/2, so the legs of one of those triangles x and 4x. This makes the length of one side equal to $\sqrt{x^{2} + (4x)^{2}} = \sqrt{17x^2} = x\sqrt{17}$ . Because all 4 sides are the same length, you multiply this value by 4, and get $4x\sqrt{17}$ , which is B.
