Answer:
55.55% decrease
Step-by-step explanation:

In the question ,
Initial point value = 9
Final point value = 4
Change% = 
The angle of rotation of a polygon is found using the formula 360/n
Where n is the number of sides.
Shape 1: 360 / 10 = 36
Shape 2: 360 /4 = 90
Shape 3: 360 /5 = 72
Shape 4: 360/8 = 45
Shape 5: 360/3 = 120
Shape 6: circles = 1
Shape 7: 360 /6 = 60
Shape 8: 360 / 12 = 30
There are 3 shapes that are 72 or higher.

The bill was $15 extra this month so 15 divided by 3 is 5.
Answer:
{-2,4,8}
Step-by-step explanation:
The range of a function represents all of the y-values.
In this case, you have y-values of (-2,4,-2, 8)
Since it hasn't been stated whether the function is continuous or not, we can just assume the function only has values at those points.
Thus the range is {-2,4,8}
Step 1: Find the circumference of the circle
Formula for circumference: C = 2 * pi * r
C = 2 * pi * 27
C = 54pi
Step 2: Find the length of the desired arc
We are only looking for 20 degrees out of 360 degrees, therefore we can multiply our circumference by 20/360.
20/360 * 54pi = 3pi units
Hope this helps!
