Central angle of a regular polygon:
Ф = 360° : n.
If n=12: Ф = 360° : 12 = 30°
At the angle of rotation Ф = 30° the image of the polygon will coincide with the preimage.

Step-by-step explanation:
<u><em>The complete question is</em></u>
James has to buy juice for his class party. there are several brands of juice at the store, and each container is a different size and price. write a formula that will help James find the price per milliliter for each brand.
x=price of juice
y=number of milliliters in carton
z=price per milliliter
we know that
The price per milliliter for each brand, is the same that the unit rate
so
To find out the unit rate , divide the price of juice by the number of milliliters in carton
so

A. A= ray and r=2
That’s the answer
Answer:
The parent sine graph
has a range of -1 ≤ y ≤ 1
It crosses the x-axis x = 0° ± 180°n
The maximum points occur when x = 90° ± 360°n and y = 1
The minimum points occur when x = 270° ± 360°n and y = -1
The sketch the graph of function
we simply move the graph of
up 2 units.
So this means it will have a range of 1 ≤ y ≤ 3
It no longer crosses the x-axis.
The maximum points occur when x = 90° ± 360°n and y = 3
The minimum points occur when x = 270° ± 360°n and y = 1
