Answer:

A. {(8,0), (0,8), (1,-6), (4,-7), (-1,8)}

Step-by-step explanation:

Any relation that maps x to more than one value of y is NOT a function.

In B, -3 is an x-value that is used twice.

In C, -1 is shown as being mapped to 10 and 18 (more than one value).

In D, the graph shows -4 produces 2 different output values.

The appropriate choice is the set of ordered pairs shown in A.

F the sphere shown above has a radius of 5 units, then what is the approximate volume of the sphere?

bogdanovich [222]

<h3>Given:</h3>

Radius= 5 units

The approximate volume of the given sphere.

<h3>Solution:</h3>

$\large\boxed{Formula:V= \frac{4}{3}\pi{r}^{3}}$

Let's substitute the values according to the formula.

Let's solve!

$V=\frac{4}{3}×\pi×{5}^{3}$

$V=523.59878 \: {units}^{3}$

Now, well have to round off to the nearest hundredth.

$\boxed{V=523.6 \: {units}^{3}}$

Hence, the volume of the given sphere is 523.6 cubic units.

Note: If your using π as π you'll get this answer.

Find the slope through each pair of two points. Report answers in simplest form.

yanalaym [24]

Answer:

m=0

Step-by-step explanation:

A general rule to remember is "rise over run" or m= $\frac{y_{2} -y_1}{x_2-x_1}$

To find the slope between these two pairs of points:

1. Choose one pair of points to be X1 and Y1 (it doesn't matter which)

In this case, let's use (-11,3) so X1 =-11 and Y1= 3

2. The second pair will be (14,3) so X2 = 14 and Y2=3

3. Applying the equation above: $\frac{y_{2} -y_1}{x_2-x_1}$

It becomes: m= $\frac{3-3}{14-(-11)}$

m = $\frac{0}{25}$

m = 0

What are the y and x intercepts of the equation y=3x-4

weqwewe [10]

The y intercept of the equation is -4. We know this because the y intercept of a linear equation always appears there in the formula.

To find the x intercept, plug 0 in for y and solve for x.

0=3x-4

*Add 4 to both sides*

4=3x

*Divide both sides by 3*

4/3=x

The x intercept of the equation is 4/3.

Hope this helps!!
