Answer:
2x^2 - 10x - 8.
Step-by-step explanation:
f(x) = 2(x - 1)(x + 4)
= 2(x^2 - x - 4x - 4)
= 2(x^2 - 5x - 4)
= 2x^2 - 10x - 8.
Yestheydo I am pretty sure

We have the following function:

And this function models the height
, in feet, of an object above ground
seconds after being launched straight up in the air. The graph of this function is shown below. So we want to know what the number 72 represents. Well, what if
?
If
we have:

Thus, <em>72 is the height of the object above the ground at
. In other words, 72 is the initial height of the ball before being launched straight up in the air.</em>
Step-by-step explanation:
A rectangular prism is shaped like a pyramid, but the base is longer in one direction than the other. i.e. a rectangle.
A cross section of a shape is the new face that is formed when you cut a shape into two pieces with a straight cut. The problem tells us that the cross section is parallel to the base of the prism, therefore if the prism is placed on a flat surface with the base facing down, then we would be cutting horizontally.
The new face that is created on the shape after the cut, would be a rectangle due to the shape of the base.
