Suppose a box is to be constructed from a square piece of material of side length x by cutting out a 2-inch square from each cor
alexgriva [62]

Consider the attached figure. The central square is the "floor" of the box, and it is a (x-2)-by-(x-2) square.

The four rectangles of the side will be the "walls" of the box, and they are (x-2)-by-2 rectangles.

The volume is given by the base area multiplied by the height of the walls, so we have

\underbrace{(x-2)(x-2)}_{\text{base area}}\times 2 = 2(x^2-4x+4)= 2x^2-8x+8

HELP ME PLEASE !!!! ill be marking brainliest
RUDIKE [14]

Using the concepts of even and odd functions, the points that will be contained in the function are given as follows:

  • Even: (-2,-5).
  • Odd: (-2,5).

<h3>What are even and odd functions?</h3>

Even and odd functions both have relationships between f(x) and f(-x), as follows:

  • For even functions, f(-x) = f(x).
  • For odd functions, f(-x) = -f(x).

This function contains point (2,-5), that is, f(2) = -5, hence:

  • For an even function, f(-2) = -5, hence it contains point (-2, -5).
  • For an odd function, f(-2) = 5, hence it contains point (-2, 5).

Find the equation of a parabola with its vertex at the origin and a focus of (-8,0)
Molodets [167]

the equation of a parabola with its vertex at the origin and a focus of (-8,0)

vertex is (0,0), h=0  and k=0

Focus is (-8,0)

Focus is (h+p, k)

We know h=0  and k=0

(0+p, 0) is (-8,0)

p = -8

General form of equation is

(y-k)^2=4p(x-h)

h=0, k=0 and p =-8

(y-0)^2=4(-8)(x-0)

y^2= -32x

Answer : option A
