The graph of x squared is the solid black graph below. Which function represents the dotted graph?

Lostsunrise [7]

Answer:

-1 ≤ y < 6

Step-by-step explanation:

The picture provided has a question of its own. The range of the graph shown is from y=-1 to (almost) y=6. The open circle tells you that the point (-11, 6) is not included in the graph. The range could be written as ...

range: -1 ≤ y < 6

In interval notations, this is ...

[-1, 6)

_____

There is no graph of a quadratic, so we cannot answer any questions related to it.

If my car averages 27 miles to the gallon, how many miles can I drive on3/4 tank of gas

AURORKA [14]

Answer:

20.25 miles

Step-by-step explanation:

If your car travels 27 miles on a full tank of gas, then your car will travel $27\cdot\frac{3}{4}$ miles on $\frac{3}{4}$ tank of gas.

$27 \cdot 0.75 = 20.25$

Solve the equations for all values of x by completing the square x^2+62=-16x

lorasvet [3.4K]

Answer:

$x = \sqrt{2} - 8\\x = -\sqrt{2} - 8$

Step-by-step explanation:

To complete the square, we first have to get our equation into $ax^2 + bx = c$ form.

First we add 16x to both sides:

$x^2 + 16x + 62 = 0$

And now we subtract 62 from both sides.

$x^2 + 16x = -62$

We now have to add $(\frac{b}{2})^2$ to both sides of the equation. b is 16, so this value becomes $(16\div2)^2 = 8^2 = 64$ .

$x^2 + 16x + 64 = -62+64$

We can now write the left side of the equation as a perfect square. We know that x+8 will be the solution because $8\cdot8=64$ and $8+8=16$ .

$(x+8)^2 = -62 + 64$

We can now take the square root of both sides.

$x+8 = \sqrt{-62+64}\\\\ x+8 = \pm \sqrt{2}$

We can now isolate x on one side by subtracting 8 from both sides.

$x = \pm\sqrt{2} - 8$

So our solutions are

$x = \sqrt{2} - 8\\x = -\sqrt{2} - 8$

Hope this helped!

The following data is a randomly selected sample of 20 state populations. find the measures of central tendency. you may use tec

GuDViN [60]

The mean is 6394530.35 and the median is = 3355572.5

The missing data is attached in the answer.

Mean is the average value of the data points , it is determined by dividing the total sum of the data points to the number of data points.

Mean and Median is the measure of the central; tendency of the data.

Mean is given by

Sum of the observations/number of observations

= (741894 + 6931071....)/20

= 6394530.35

2) To find median

The data needs to be arranged in ascending order

Then the median is the middle number of the arranged data

Here the median is = 3355572.5
