Hope it is helpful...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
4+9 because i need to waste my points
Answer:
ummmmm i think apple?
Step-by-step explanation:
because if 4 equals green and you put the square root of branch in there you will get branch×apple tree+water=apple my bad its green apple
i did it wrong i just redid the question and found the right answer. so if you put branch×square root of 9 apples+apple tree=9 apples right? well yes but if you add branch+square root of 4 more apples you will get in total 13 apples.

Answer:
6
Step-by-step explanation:
Answer:
I am pretty sure it's 495
Step-by-step explanation:
The context of this problem makes me think that the order in which the sites are in does not matter
if that's the case we can solve this using combinations
the combinations formula is as follows:
ACB= [tex]\frac{A!}{(A-B)!*B!}[/tex]

Answer:
33.48
Step-by-step explanation:
Find the diagram attached
Opposite = 32
Hypotnuse = 58
Sin theta = opposite/hypotenuse
Sin theta = 32/58
Sin theta = 0.5517
theta = arcsin(0.5517)
theta = 33.48

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

hi I am sorry I wish I could help
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 )

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.

Answer:
30m x 40m
Step-by-step explanation:
The diagram is 15cm x 20cm
since 1cm = 2m
the backyard measures
30m x 40m
Answer: The backyard is 30 meters by 40 meters
30 meters = horizontal dimension
40 meters = vertical dimension
===========================================================
Explanation:
The pool on paper is 7.5 units across horizontally. Applying the scale factor, we can see that it corresponds to 7.5*2 = 15 meters
The 20 meter portion is vertical. On paper, we see that it's 10 units tall. So the "times 2" operation applies to jump from 10 cm to 20 meters
Or you could note that the ratio 1 cm : 2 m scales up to 10 cm : 20 m after multiplying both parts by 10.
-----------------
With that in mind, all we need to do really is count the number of squares across the top and along the left side. Across the top, we have 15 squares. That 15 cm corresponds to 15*2 = 30 meters in length.
Along the left side, the figure is 20 cm tall. So that corresponds to 20*2 = 40 meters.
The backyard is 30 meters by 40 meters. This includes the backyard, shed, and other features in the diagram. The entire backyard is 30*20 = 600 square meters. If you wanted to know the area of the grass only, then you'd subtract off the areas of the pool, shed, etc.
-----------------
Your teacher mentions that the pool is similar to the backyard overall. Since we're in a geometry setting, the word "similar" is very specific of course.
We can match up the corresponding lengths to form a proportion like so
(large horizontal)/(small horizontal) = (large vertical)/(small vertical)
30/15 = 40/20
2 = 2
So that confirms we have similar figures, at least in terms of the sides being proportional. Everything being a rectangle helps show that all angles are the same.
Complete the missing parts of the

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]

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.
Hope this helps!
