Okay so what you do if you put your pencil on the graph and draw multiple lines through you points, if any of you straight lines go through two points then it does not pass, but your graph in that picture will pass the vertical line test

Ok, so I'm not entirely sure since I haven't done this in a while, but here's a link to help.

My guess would be, before even reviewing the video, is that it is not. Because it's called a VERTICAL line test it makes me think it may be a function if the points are in a vertical line and not a curve like in the above picture. 
:)
Good luck with your assignment. Message me if you need more help.

Find the approximate side length of a square game board with an area of 179in ^2.
zysi [14]
<h3><u>Given</u><u>:</u><u>-</u></h3>

Area of a square game board = 179 inches ²

<h3><u>To</u><u> </u><u>be</u><u> </u><u>calculated</u><u>:</u><u>-</u></h3>

Calculate the side of given square game board.

<h3 /><h3><u>Formula</u><u> </u><u>applied</u><u>:</u><u>-</u></h3>

Area of square = ( Side )²

<h3><u>Solution</u><u>:</u><u>-</u></h3>

We know that,

Area of square = ( Side )²

★ Substituting the value in the above formula, we get :

=> 179 = ( Side )²

=> Side = √179

=> Side = 13.37 inches ( approx )

The class scores of a history test have a normal distribution with a mean Mu = 79 and a standard deviation Sigma = 7. If Opal’s
storchak [24]

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

<h3>What is normally distributed data?</h3>

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,

Z=\dfrac{X-\mu}{\sigma}

The mean value of the scores of history class is,

\mu=79

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

\sigma=7

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

z=\dfrac{72-79}{7}\\z=-1

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

Help is it A or B? pls help
Damm [24]

Answer:

f(x)=-(x+8)(x-2)

Step-by-step explanation:

Start by factoring out a -1...

f(x)=-(x^2+6x-16)

Now, we have to find two integers that multiply to get -16 and have a sum of 6:

(-2)*8=-16

-2+8=8-2=6

Using this, we can split 6x into -2x and 8x...

f(x)=-(x^2-2x+8x+16)

Factor  the first and second half separately...

f(x)=-[(x^2-2x)+(8x-16)]\\f(x)=-[x(x-2)+8(x-2)]\\

Since both x and 8 are being multiplied by x-2, we can combine them to get...

f(x)=-(x+8)(x-2)

What is the quadratic equation if the solutions are -9+ √65 /2, -9- √65 /2
liberstina [14]

Answer:

4x^2+72x+259=0

Step-by-step explanation:

If x_1 and x_2 are the solutions to the quadratic equation, then this equation can be written as

(x-x_1)(x-x_2)=0

In your case,

x_1=-9+\dfrac{\sqrt{65}}{2}\\ \\x_1=-9-\dfrac{\sqrt{65}}{2}

Then the equation is

\left(x-\left(-9+\dfrac{\sqrt{65}}{2}\right)\right) \left(x-\left(-9-\dfrac{\sqrt{65}}{2}\right)\right)=0\\ \\\left(x+9-\dfrac{\sqrt{65}}{2}\right)\left(x+9+\dfrac{\sqrt{65}}{2}\right)=0\\ \\x^2+9x+\dfrac{\sqrt{65}}{2}x+9x+81+\dfrac{9\sqrt{65}}{2}-\dfrac{\sqrt{65}}{2}x-\dfrac{9\sqrt{65}}{2}-\dfrac{65}{4}=0\\ \\x^2+18x+\dfrac{259}{4}=0\\ \\4x^2+72x+259=0
