Which solid of revolution is produced by rotating the shape below 360° about the given axis?

<h3>Answer: Choice A</h3>

Explanation:

When we rotate a rectangle around an axis of symmetry, we end up with a cylinder. Think of a revolving door or a turbine. The flat door moves through 3D space to produce or carve out a 3D cylinder.

This figure is composed of two rectangles, so we'll end up with two cylinders. They will both share the same center, so we'll have a sideways two-layer wedding cake structure when everything is said and done. This points to choice A as the final answer.

<span>Ned scored 2p+3. Tony scored 3 points more than Ned, so Tony scored 3+2p+3, or 2p+6. Matt scored twice as many points as Tony, so Matt scored 2(2p+6), or 4p+12. Juan scored 8 fewer points than Ned, so Juan scored 2p+3-8, or 2p-5. To simplify, we add these four values. 2p + 3 2p + 6 4p + 12 2p - 5 This equals 10p + 16.</span>

What is the equation of the line slope of 3 and passes through the point (-2, 3)?
elixir [45]

Answer:

\large\boxed{y-3=3(x+2)}\qquad\text{point-slope form}\\\boxed{y=3x+9}\qquad\text{slope-intercept form}\\\boxed{3x-y=-9}\qquad\text{standard form}\\\boxed{3x-y+9=0}\qquad\text{general form}

Step-by-step explanation:

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

We have the slope m = 3 and the point (-2, 3). Substitute:

y-3=3(x-(-2))\\\\y-3=3(x+2)

the point-slope form

y-3=3(x+2)        <em>use the distributive property</em>

y-3=3x+6           <em>add 3 to both sides</em>

y=3x+9

the slope-intercept form

y=3x+9           <em>subtract 3x from both sides</em>

-3x+y=9         <em>change the signs</em>

3x-y=-9

the standard form

3x-y=-9              <em>add 9 to both sides</em>

3x-y+9=0

the general form
