Answer:

C

Step-by-step explanation:

Look at your Y-values. If you look at the constant difference for A. You will get a constant difference of 4 meaning its linear. B will give you a constant difference of 9 which also means that it is linear. D has a Constant difference of 1. However, C has no constant difference as the difference between each value changes, therefore meaning that it is not linear

Answer:

B. (x+4)(x-4)

Step-by-step explanation:

We are given:

[tex]y=\frac{2x}{x^2-16}[/tex]

And asked to factor the denominator.

When factoring, you have a^2 + bx + c, and when wanting to turn it into a binomial, you have to find two numbers that multiply to c and add up to b.

In this case, we see that c is equal to -16. List out the factor of -16:

±1 , ±16

±2 , ±8

-4 , 4

Now we see that b is not present, therefore being 0. Our goal is to find two factors of -16 that will equal to 0 when added.

1 and 16 will never make 0

2 and 8 cannot make 0 either

4 and 4 can make 0, and since 16 is a negative number, one 4 needs to be negative while the other is a positive.

Basically stating, our factor of the denominator is:

[(x + 4)(x - 4)]

The value of z score for the history class test of Opal’s test score is negative one (-1).

Normally distributed data is the distribution of probability which is symmetric about the mean.

The mean of the data is the average value of the given data. The standard deviation of the data is the half of the difference of the highest value and mean of the data set.

The z score for the normal distributed data can be given as,

[tex]Z=\dfrac{X-\mu}{\sigma}[/tex]

The mean value of the scores of history class is,

[tex]\mu=79[/tex]

The standard deviation value of the scores of history class is,

[tex]\sigma=7[/tex]

Here, the test score of the Opal’s is 72. Thus the z score for her test score can be given as,

[tex]z=\dfrac{72-79}{7}\\z=-1[/tex]

Hence, the value of z score for the history class test of Opal’s test score is negative one (-1).

Answer:

Answer is A  on edge

Step-by-step explanation:

========================================================

Explanation:

r = radius of the circle = 3

This is because segment IJ is 3 units.

Let's find the area of a full circle based on this radius.

A = pi*r^2

A = pi*3^2

A = 9pi

That's the area of a full circle with radius 3.

However, we only have a small pizza slice shaded. This slice has area of (1/2)pi or pi/2

If we divided the area of the slice over the full area, then we can figure out how many equal such slices make up the full circle.

(9pi)/(pi/2) = 9pi*(2/pi) = 18

This pizza has 18 slices total. Each slice has area pi/2 and it gives a total area of 18*(pi/2) = 9pi

The jump from pi/2 to 9pi is exactly "times 18" to represent the 18 slices.

--------------------

Since we now know that this pizza has 18 equal slices, we'll cut a full 360 degree rotation into 18 equal pieces

360/18 = 20

Therefore, the central angle KIJ is 20 degrees.

Plug this central angle, along with the radius, into the arc length formula

L = arc length

L = (circumference)*(angle in degrees)/360

L = (2*pi*r)*(20/360)

L = 2pi*9*(1/18)

L = pi

Arc KJ is exactly pi units long.

--------------------

Paraphrased another way:

The full distance around the circle is 2*pi*r = 2*pi*9 = 18pi units

However, we only want a slice of this perimeter. We divide by 18 because we found earlier that there are 18 equal slices.

So each slice has its curved portion, aka arc length, being (18pi)/18 = pi units

Step-by-step explanation:

When she got up, the temperature was 58°F.

It rose 21°F, rose another 8°F, then drop 23°F

=> + 21 + 8 - 23
So, the temeperature when Emily went to bed was : 58 + 21 + 8 - 23 = 64°F

Answer: It's not

Step-by-step explanation:

A perfect square is always [tex](x+y)^{2}[/tex], where [tex]x^{2} +2xy+y^{2}[/tex].

Knowing this, we can square root 144x to get 12x. Square rooting 81 gets us 9. Unfortunately, if we multiply 12 and 9 together, then double it, we get 216, which is definitely not 200.

Therefore, the polynomial is not a perfect square.
