Answer:

The amount of popcorn needed to fill the paper cone is $V=1,005\ cm^{3}$

Step-by-step explanation:

we know that

The volume of a cone is equal to

$V=\frac{1}{3}\pi r^{2} h$

In this problem we have

$r=8\ cm$

$h=15\ cm$

$\pi =3.14$

substitute

$V=\frac{1}{3}(3.14)(8)^{2}(15)$

$V=1,005\ cm^{3}$

Answer:

Step-by-step explanation:

Let's first find the slope of the linear function represented by the table:

As we move from x = 4 to x = 6 *an increase of 2), y increases by 6 from -2 to +4. Thus, the slope of this line is m = rise / run = m = 6/2, or 3.

Now we compare the two slopes: -2 and 3.

The postive difference between them is 5. This is Answer B.

Answer:

In a nutshell, $g(x) = x+2$ .

Step-by-step explanation:

A composition is operation between function that consist in replacing the independent variable of the first function, $f(x)$ in this case, for $g(x)$ . Common notations for composition between functions are $f(g(x))$ and $f\circ g (x)$ . If we know that $h(x) = f\circ g (x) = (x+2)^{2}$ and $f(x) = x^{2}$ , then $g(x) = x+2$ .

In a nutshell, $g(x) = x+2$ .
