Answer:

Step-by-step explanation:
The reflection of a function
along the
is given by
.
Here the given function is
. Therefore the reflection would be
.
To find reflection draw the graph of it and think about how the graph of its mirror image would be. You would arrive at the reflection function.
First, find the hypotenuse of the triangle with leg lengths 4 and 4. Use special triangle theorem:
1:1:sqrt(2) 4:4:4*sqrt(2)
Use the Pythagorean Theorem to find x:
2^2 + (4sqrt2)^2 = x^2
x^2 = 36
x = 6, or choice (D).
Answer:
C. 1.5 cm
Step-by-step explanation:
A pentagon is a polygon with 5 sides.
The formula for the area of a regular polygon is

where a is the apothem and p is the perimeter. The perimeter is found by multiplying the number of sides of the figure by the length of 1 of those sides:
5(2.2) = 11
Now we have everything we need to solve for the length of the apothem.

Begin by multiplying both sides by 2 to get rid of the fraction, so
16.6 = 11a Divide both sides by 11 to get
a = 1.5090909 or
C. 1.5 cm
Answer:
13
Step-by-step explanation:
<em>Here, each of the 5 friends has an x action figure. When they buy 11 more we have 5(x+11). Now they have a total of 120 action collections and here we have 5(x+11)=120</em>

<em>Hence, each of the friends has 13 action collections originally.</em>
