A regular decagon has 10 sides. How many reflectional symmetries does a regular decagon have?
lina2011 [118]

The rule for regular polygons are very easy. The number of reflectional symmetries is same as the number of sides. Regular polygons have all sides the same length and all angles same. Reflection symmetry means that you can fold the shape along that line and it will match up.

For this question, we want the number of reflectional symmetries of a regular decagon. Decagon is a 10 sided figure. Hence, the number of reflectional symmetries is 10.

There are 5 symmetry lines from one vertex to opposite vertex and 5 more symmetry lines form midpoint of one side to midpoint of opposite side.

One model for car depreciation is as follows, where C is the original cost, V is the value of the car after t years, and is the
grandymaker [24]

Answer:

C $9,318

Step-by-step explanation:

In order to find the answer you have to use the formula provided to calculate the value of the car after t years:

V=C(1-r)^t

C=$21,000

r=15%

t=5

V=21,000*(1-0.15)^5

V=21,000*0.4437

V=9,318

According to this, the answer is that the value of the car after 5 years is $9,318.
