Which graph is correct?
Let's first take a look at our x here. --- (x + 2)^2
Because we are adding a two to our x, this means that we are shifting our graph 2 to the left. Remember that with functions, it's always the opposite!
There is nothing attached to the y, so we are not moving our function up or down.
And then the radius of our circle. Remember that the equation requires us to square this value (... = r^2), so we need to take the square root of 4. The square root of 4 is 2.
With this information, let's now look at our options.
Option A - INCORRECT, the radius is too large
Option B - INCORRECT, this was shifted 2 units to the right
Option C - INCORRECT, the radius is too large
Option D - CORRECT, the radius is 2 and the circle was shifted 2 units to the left
Hope this helps!! :)
Answer:
D
Step-by-step explanation:
The equation for a circle is
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x+2)^2 + (y)^2 = 4
Rewritng
(x- -2)^2 + (y-0)^2 = 2^2
The center is at ( -2,0) and the radius is 2
C and D are the only circles with a center at (-2,0)
B,D are the only circles with radius 2

The height of the cone is 11.6 centimeters.
What is a cone?'A cone is a shape formed by using a set of line segments or the lines which connects a common point, called the vertex, to all the points of a circular base. The distance from the vertex of the cone to the base is the height of the cone. The circular base has the measured value of radius. And the length of the cone from the vertex to any point on the circumference of the base is the slant height.'
According to the given problem.
Given,
Diameter = 6 cm
Radius = 6/2 cm
= 3 cm
Slant height (l) = [tex]\sqrt{r^{2} + h^{2} }[/tex]
⇒ l² = r² + h²
⇒ l² - r² = h²
⇒ 12² - 3² = h²
⇒ 144 - 9 = h²
⇒ h² = 135
⇒ h = √135
⇒ h = 11.6 cm
Hence, the height of the cone is 11.6 centimeters.

Complete the missing parts of the
table for the following function.
y = ()*
X-2 -1
0 1 2 3
y 36 [?] 1 1

216
Answer:
Remember the property:
a^-1 = (1/a)^1
and:
(a/b)^n = (a^n)/(b^n)
A table for a function like:
[tex]\left[\begin{array}{ccc}x&f(x)\\&\\&\\&\\&\end{array}\right][/tex]
Is just completed as:
[tex]\left[\begin{array}{ccc}x&f(x)\\x_1&f(x_1)\\x_2&f(x_2)\\x_3&f(x_3)\\x_4&f(x_4)\end{array}\right][/tex]
So, here we have:
y = f(x) = (1/6)^x
To complete the table, we need to find:
f(-1)
and
f(2)
So let's find these two values:
f(-1) = (1/6)^-1 = (6/1)^1 = 6
and the other value is:
f(2) = (1/6)^2 = 1/36
Then the complete table is:
[tex]\left[\begin{array}{ccc}x&f(x)\\-2&36\\-1&6\\0&1\\1&1/6\\2&1/36\\1&1/216\end{array}\right][/tex]

Answer:
x ≈ 6.2
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² + 17.1² = 18.2²
x² + 292.41 = 331.24 ( subtract 292.41 from both sides )
x² = 38.83 ( take the square root of both sides )
x = [tex]\sqrt{38.83}[/tex] ≈ 6.2 ( to the nearest tenth )

-5(x+7)<-10 write an inequality for x
Answer:
x > -5
Step-by-step explanation:
[tex]-5(x+7)<-10\\x+7>2\\x>-5[/tex]
Answer:
x > -5
Step-by-step explanation:
-5 (x+7) < -10
The next step is to divide both sides by -5 and flip the sign
(x+7) > [(-10/(-5)]
x+7 > 2
Finally, subtract both sides by 7
x > 2-7
x > -5
What is the value of x?
Answer:
x =127
Step-by-step explanation:
Since this is a 6 sided figure, the sum of the interior angles is 720
128+133+112+x+120+100 = 720
Combine like terms
x+593=720
Subtract 593 from each side
x+593-593 = 720-593
x =127
Hint :
Sum of angles of the 6 sided figure = [tex] {720}^{o} [/tex]
Answer:
[tex] {x}^{o} = {127}^{o} [/tex]
Step-by-step explanation:
[tex] {x}^{o} + {112}^{o} + {133}^{o} + {128}^{o} + {100}^{o} + {120}^{o} = {720}^{o} \\ {x}^{o} + {593}^{o} = {720}^{o} \\ {x}^{o} = {720}^{o} - {593}^{o} \\ {x}^{o} = { 127}^{o} [/tex]

Carlos is saving money to buy a set of golf clubs that cost $530. He already has $80.00 saved and can earn the rest of the money by mowing 15
lawns. If m represents how much he earns for mowing each lawn, which of the following equations can be solved to find how much Carlos is paid for
mowing each lawn?
Answer:
15m+80 would be the correct equation
Answer:
15*m=(530-80)
Step-by-step explanation:
30$ per lawn. 530-80=450. This gives us how much money he still needs to buy his gulf clubs. But, the question says that Carlos can earn the rest of the money ($450) by mowing 15 lawns.
Here's how we model that as an expression:
15m=(530-80)
15 lawns for m dollars would get him 530-80 (450) or the remaining amount.

Which tables could be used to verify that the functions they represent are inverses of each other? Select two
options.
Why? Because they are mirrors of each other. In other words, one table has its x and y row swapped compared to the other table.
The input x = -120 leads to the output y = 627 in table C. Then in table D, we have the input x = 627 to go the output y = -120. Refer to the first column of each table mentioned. The same applies for the other columns as well. The inverse table undoes everything the original table does.
The tables that could be used to verify inverse functions are tables C and D
What are inverse functions?The inverse of a function are the opposites of the function
From the list of options, we can see that:
The x values of table C are the y values of table D
Also, the x values of table D are the y values of table C
This means that tables C and D are inverse functions
Hence, the tables that could be used to verify inverse functions are tables C and D

Answer:
1,100 is your area
Step-by-step explanation:
First we cut the shape into three, two triangles and a square, the formula to find the area of a square is A=a^2 (a is the side)
A=25^2
A=625
now to find the triangles the formula to find the are we use the right angled triangle formula twice which is A=a*b/2
A=25*19/2
A=475/2
A=237.5
now add them all up
