Hello! The y-intercept is (0, 4), because the line crosses 0 in the x-axis at that point. We can cross out C and D, because those don't show that. The slope is rise/run. You would go up 3, and go to the right once. If you need to, solve for slope by doing y2 - y1/ x2 - x1. Let's use the point (0, 4) and (1, 7) as an example. We would set it up like this: 7 - 4 / 1 - 0. Solving that would give us 3/1 or just simply three. The slope is positive 3 and the y-intercept is (0, 4). The answer is A.

A cylinder is placed within a cube. The diameter of the cylinder is equal to the length of each side of the cube. What is the vo

The volume of a shape is the amount of space in it.

<em>The volume outside the cylinder, but inside the cube is 214.6 cubic inches</em>

The given parameter is:

$l = 10$ ---- length of the cube

So, the volume of the cube is:

$V_1 = l^3$

$V_1 = 10^3$

$V_1 = 1000$

The volume of the cylinder is:

$V_2 = \pi r^2h$

The diameter (d) of the cylinder equals the length of the cube.

This means that:

$d = l$

$d = 10$

Divide by 2 to calculate the radius of the cylinder

$r = \frac{10}{2}$

$r = 5$

Also, the height of the cube is::

$h =l$

$h =10$

So, we have:

$V_2 = \pi r^2h$

$V_2 = \pi \times 5^2 \times 10$

$V_2 = \pi \times 25 \times 10$

$V_2 = \pi \times 250$

$V_2 = 785.4$

So, the volume (V) outside the cylinder is:

$V = V_1 - V_2$

$V = 1000 - 785.4$

$V = 214.6$

Hence, the volume outside the cylinder is 214.6 cubic inches

Simplify.<br> (-8V2)(+1/2V32)

erastovalidia [21]

Hello!!

$\rule{300}{5}$

$\huge\blue{{\fbox{\tt{ANSWER:-\:}}}}$

$-32$

$\huge\red{{\underline{\overline{\textbf{MY\:EXPLANATION~!}}}}}$

Apply rule: $(-a) = -a$

$(-8\sqrt{2}) = - 8\sqrt{2}$

$= -8\sqrt{2}~\frac{1}{2}\sqrt{32}$

$\sqrt{2}~\sqrt{32} =\sqrt{64}$

$= -8\sqrt{64}~\frac{1}2}$

$\sqrt{64} = 8$

$= -8$ · $8$ · $\frac{1}{2}$

Multiply the numbers: $-~8$ · $8= -64$

$=-64$ · $\frac{1}{2} = -32$

$= -32$

Hope It Helps. . .
