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]

Find the area of the polygon.
20 cm
14 cm
4 cm
3 cm
5 C
Answer:
The area of the given polygon is:
232 cm^2Step-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 * heightNow, we're gonna replace the measurements in the formula.
First rectangle:
Area of a rectangle = 3 cm * 14 cmArea of a rectangle = 42 cm^2Second rectangle:
Area of a rectangle = 5 cm * 14 cmArea of a rectangle = 70 cm^2Third rectangle:
Area of a rectangle = 12 cm * 10 cmArea of a rectangle = 120 cm^2By 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^2As you can see, the area of the polygon in the picture is 232 cm^2.
100 POINTS What is the volume of this cone? Use 3.14 for N
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.
[tex]68.64pi[/tex]
This is your answer!
Hope this helps! :D

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

Suppose Paul kicks a soccer ball straight up into the air with an initial velocity of 96 feet per second. The function h(t)= -16t^2+96t gives the height, in feet, of the soccer ball after t seconds. The function is shown in the graph below. What are the intercepts of the function and what do they mean?
Answer:
(d)
Step-by-step explanation:
Given
[tex]h(t) = -16t^2 + 96t[/tex]
Required
The intercepts
The x intercepts are where the graph crosses x axis.
From the attached plot, they are:
[tex]x = (0,0)[/tex] and [tex]x = (6,0)[/tex]
These represent the start and end of the ball that is launched.
Hence, (d) is true

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?
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:
15 = 3x
15/3 = x

PLEASE HELPPP!!!!!!!!
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.

Approximately 0.5% of computers in a shipment arrive broken. In a shipment of 20,000 computers, about how many will NOT be broken?
Rewrite 0.5% as a decimal by moving the decimal point 2 places to the left:
0.5% = 0.005
Multiply quantity by the decimal:
20,000 x 0.005 = 100 would be broken
20,000-100 = 19,900 would not be broken

From $25 to $35
The percent increase is
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.

4 in.
12 in.
24 in.
36 in.
Answer:
36
Step-by-step explanation:
I used a triangle height calculator on G0ogle
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
