Answer:

$V = 864cm^3$

Step-by-step explanation:

Given

$r = 6$

$\pi = 3$

Required

The volume of the sphere

This is calculated as:

$V = \frac{4}{3} \pi r^3$

So, we have:

$V = \frac{4}{3} *3 *6^3$

$V = \frac{4}{3} *3 *216$

This gives:

$V = 4 *216$

$V = 864$

Someone please help<br> Me algebra 2

Bumek [7]

Answer:

Table I fill-in: 1.404

Table II fill-in: 1.661 (instead of the 2 that's there)

Step-by-step explanation:

The functions shown in Table I and II are inverses of each other. This means that the x's for Table I are the y's in Table II. And the y's in Table I are the x's in Table II.

So look at Table II, there is a coordinate pair

(7, 1.404). Switch the x and y and you get (1.404,7) That's your answer to fill in on Table I.

What is 52,437 rounded to the nearest thousand?

saul85 [17]

<h3>What is 52,437 rounded to the nearest thousand?</h3>

Answer: 52,000

Step-by-step explanation:

We have to look at the number in the hundredth place and if it is less than five we round down, but if it is five or more, we round up.

In this case, since we have 52,437, the number of hundreds is 4, so we have to <u>round down</u>. 52,000.

Plot six lines. Each line should pass through the origin and one of the six points. One is done for you.

frutty [35]

<h3>Solution (Line 2): <u>(Refer to graph 1)</u></h3>

Given points: (0, -2) and (1, -4)
Slope formula: Rise/Run
Point slope form formula: y - y₁ = m(x - x₁)

To create the equation of the line, find the slope. Then, use point slope form to find the equation of the line.

<u>Use the slope formula to find the slope.</u>

Rise/Run = Slope
=> Rise = -2; Run = 1
=> Rise/Run = -2/1 = -2

<u>Use the point slope form formula.</u>

y - y₁ = m(x - x₁) = Equation of line.
=> y - (-4) = -2(x - 1) = Equation of line.
=> y + 4 = -2x + 2
=> y = -2x + 2 - 4
=> y = -2x - 2

<h3>Solution (Line 3): <u>(Refer to graph 2)</u></h3>

Given points: (0, -2) and (-4, 3)
Slope formula: Rise/Run
Point slope form formula: y - y₁ = m(x - x₁)

To create the equation of the line, find the slope. Then, use point slope form to find the equation of the line.

<u>Use the slope formula to find the slope.</u>

Rise/Run = Slope
=> Rise = -5; Run = 4
=> Rise/Run = -5/4

<u>Use the point slope form formula.</u>

y - y₁ = m(x - x₁) = Equation of line.
=> y - 3 = -5/4{x - (-4)} = Equation of line.
=> y - 3 = -5/4{x + 4}
=> y - 3 = -5x/4 - 5
=> y = -5x/4 - 2

<h3>Solution (Line 4): <u>(Refer to graph 3)</u></h3>

Given points: (0, -2) and (-3, -5)
Slope formula: Rise/Run
Point slope form formula: y - y₁ = m(x - x₁)

To create the equation of the line, find the slope. Then, use point slope form to find the equation of the line.

<u>Use the slope formula to find the slope.</u>

Rise/Run = Slope
=> Rise = 3; Run = 3
=> Rise/Run = 3/3 = 1

<u>Use the point slope form formula.</u>

y - y₁ = m(x - x₁) = Equation of line.
=> y - (-5) = 1{x - (-3)} = Equation of line.
=> y - (-5) = 1{x + 3}
=> y + 5 = x + 3
=> y = x - 2

Which graph has slope of 2

Vlad [161]

Answer:

Step-by-step explanation:

It would be D because the formula to find slope is y divide by x. Graph D has a y of 2 and a x of 1 which you divide to get 2 which would be your answer
