The equation of the circle is always:
$(x - h)^{2} + (y-k)^{2} = r^{2}$
Where (h, k) is the center of the circle, r is the radius. So, the equation will be:
$x^{2} + y^{2} = 64$
Hope this helps! The answer is B.

Factor the polynomial function over the complex numbers.

Bumek [7]

Answer:

$[x - 1][x + 1][{x}^{2} + 4]$

Step-by-step explanation:

Knowing that you have to find two numbers that when they differ to 3, they also multiply to −4, and those numbers are −1 and 4. So, after clearing that up, you will have this [since our degree of this polynomial function is 4]:

$[{x}^{2} - 1][{x}^{2} + 4]$

Then, since ${x}^{2} - 1$ is factorable, you will get this:

$[x - 1][x + 1]$

Finally, attach $[{x}^{2} + 4]$ to the partially factored polynomial to get this:

$[x - 1][x + 1][{x}^{2} + 4]$

Create a dot plot of the data shown below. 20, 21, 21, 25, 20, 23, 27, 23, 24, 25, 26, 24, 23, 22, 24 Which measure of center wo

The measure of center that would best describe a typical value of the data set is a mean since the values are close.

<h3>What is a measure of center?</h3>

It should be noted that the measure of center include the mean, median, mode, and the mid-range.

In this case, when there is a close distribution of different numbers, he beta measurement will be the mean.

Therefore, the mean of the numbers will be:

= (20 + 21 + 21 + 25 + 20 + 23 + 27 + 23 + 24 + 25 + 26 + 24 + 23 + 22 + 24)/15

= 348/15

= 23.2
