Answer:
a. 2/5; reduction
Step-by-step explanation:
It appears that C is the center of dilation, so C' and C are coincident. The scale factor is ...
P'C'/PC = 4/10 = 2/5 . . . scale factor
The scale factor is less than 1, so the dilation is a <em>reduction</em> in size.

In this problem, we need to use squaring method.
5² means 5 × 5
5² = 25
12² means 12 × 12
12² = 144
So, simplify these statements:
5² × 12²
25 + 12² (Simplify 5², which means 5 × 5)
25 + 144 (Simplify 12², which means 12 × 12)
We get the answer:
25 + 144 =

The numbers will be X and Y with X being the lesser
x+y=45
2y=5x+6
now use a subtraction method to solve
x+y=45
y=45-x
2 (45-x)=5x+6
90-2x=5x+6
-7×=-84
x=12
y=45-12
y=33
so, x=12 and y=33
Frequency = 1/period
Frequency = 1 / 0.001136
Frequency = 880.2816 Hz
Rounded to the nearest frequency = 880 Hz
