what value is needed to complete the square?
X²-2x + _______

Answers

Answer 1

Answer:

[tex]X^2-2x+1[/tex]

Step-by-step explanation:

Traditional pattern for a perfect square:

[tex]x^{2} +2ax+a^{2}[/tex]

Which factors into: [tex](x+a)^2[/tex]

We know becuase a is "missing" from the original equation that it must equal 1; therefore:

[tex]x^2+2x+1[/tex]

Which we know is correct because it factors into: [tex](x+1)^2[/tex]

4 in.
12 in.
24 in.
36 in.

Answers

Answer:

If the base area is 162 square inches, then the height of the pyramid will be 36 inches. Then the correct option is D.

What is Geometry?

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

A pyramid has a volume of 1,944 inches cubed and a rectangular base with the dimensions of 18 inches by 9 inches.

Then the height of the pyramid will be

The volume of the pyramid will be

Volume = (Base area x height) / 3

Then the base area will be

Base area = 18 x 9

Base area = 162 square inches

Then the height of the pyramid will be

1944 = (162 h) / 3

5832 = 162 h

      h = 36

Sketch a graph of a quadratic function that has a maximum value of (0, 2) and x-intercepts when x = +2.​

Answers

The graph of a quadratic function that has a maximum value of (0, 2) and x-intercepts when x = ± 2 is plotted and attached.

What is local maxima and minima?

Local Maxima

If f'(x) changes sign from positive to negative as x increases via point c, then f(c) represents the maximum value of the function in that range.

Local Minima

If f'(x) changes sign from negative to positive as x increases via point c, then f(c) gives the minimum value of the function within that range.

Given is to sketch a graph of a quadratic function that has a maximum value of (0, 2) and x-intercepts when x = + 2.​

Refer to the graph of the function attached.

It shows a parabola indicating a quadratic function that has a maximum value of (0, 2) and x - intercepts at x = ± 2.​

Therefore, the graph of a quadratic function that has a maximum value of (0, 2) and x-intercepts when x = ± 2 is plotted and attached.

David has $40 in his savings account. Every week, he deposits $3. Perla has $25 in her account. She deposits $6 every week. After how many weeks will David and Perla have the same amount of money?

Answers

Answer:

at 5 weeks

Step-by-step explanation:

y = 3x + 40   (David)

y = 6x + 25  (Perla)

since both equal 'y' we can set the expressions equal and solve for 'x'

3x + 40 = 6x + 25

subtract 3x from each side to get:

40 = 3x + 25

subtract 25 from each side to get:

PLEASE HELPPP!!!!!!!!

Answers

Answer:

C. y=-3x+5

Step-by-step explanation:

Looking at the line, you see that it goes down 3 places for every unit step to the right, so the slope is -3 and we expect a -3x in the answer.

Looking at the intersection with the y-axis, it is at (0,5), so we expect -3x + 5.

We have to be at the left of this line, i.e. y < -3x + 5.

Find the area of the polygon.
20 cm
14 cm
4 cm
3 cm
5 C

Answers

Answer:

The area of the given polygon is:

232 cm^2

Step-by-step explanation:

To find the area of the polygon in the picture, you can divide the polygon in three rectangles: a 3 cm by 14 cm, a 5 cm by 14 cm rectangle, and the last rectangle must have a base of 12 cm (20 cm - 3 cm - 5 cm), and a height of 10 cm (14 cm - 4 cm). We can calculate the area of the rectangles with the formula below:

Area of a rectangle = Base * height

Now, we're gonna replace the measurements in the formula.

First rectangle:

Area of a rectangle = 3 cm * 14 cmArea of a rectangle = 42 cm^2

Second rectangle:

Area of a rectangle = 5 cm * 14 cmArea of a rectangle = 70 cm^2

Third rectangle:

Area of a rectangle = 12 cm * 10 cmArea of a rectangle = 120 cm^2

By last, we must add the area of the rectangles:

Area of the polygon = 42 cm^2 + 70 cm^2 + 120 cm^2Area of the polygon = 232 cm^2

As you can see, the area of the polygon in the picture is 232 cm^2.

Answer:

D. 215.5

Step-by-step explanation:

The formula for this equation is V= 3.14 x [tex]6^{2}[/tex] x 5.72 ÷ 3

Plug all of that into your calculator and you should get 215.5296.

From here just round to the nearest tenth and you'll be left with answer D. 215.5

Answer:

68.64pi or 215.64

Step-by-step explanation:

So lets go over the formula for volume of a cone.(note if needed for future problems, this can also be used for pyramid.)

The formula is:

r^2*h*pi*1/3

Or:

[tex]\frac{r^2*h*\pi }{3}[/tex]

We know that the radius is 6.

We also know that 5.72 is height.

Lets plug these in:

[tex]\frac{6^2*5.72*pi}{3}[/tex]

Now square the 6.

[tex]\frac{36*5.72*pi}{3}[/tex]

Now multiply the 36 by 5.72.

[tex]\frac{205.92*pi}{3}[/tex]

Combine the 205.92 and pi.

[tex]\frac{205.92\pi }{3}[/tex]

Finally, divide by the 3.

Answer:

40 percent

Step-by-step explanation:

Start by taking the difference of the two values:

35-25 = 10.

the $10 is how much the value increased by.

To get the percent that the $25 increased by, take 10/25 to get .4

This .4 can then be turned into a percentage when you multiply it by 100. = 40 percent.

You can check your answer by finding 40 percent of 25, which is 10.
