The answer is the last choice. (a, b), in this question, means the domain or range is from a to b, exclusive. When you use ∞, you would always use the exclusive.
18/5 is basically 3 3/5 as a mixed number. When you convert a fraction to a decimal, you always want the denominator to either 10, 100, or 1000 so that the number is accurate. And so you multiply the denominator by what ever number will get 10, 100 or 1000, in which in this case is 10 when you multiply by 2. Multiply the numerator(3) by 2 so that it will be the same value. You should now have 3 6/10. After that, since 6/10 is basically 60/100, take out the 100 and move the decimal unit 2 units to the left of 60. And since you still have the whole number three, your final answer will be 3.6.

Answer:
D.252
Step-by-step explanation:
In this question, We have to find which rotation about its center will carry a regular decagon onto itself?
A decagon : 10 sided polygon
As we know, a full rotation can be 360°.
For a decagon: 360/10 =36
For a decagon, any multiple of 36 can map onto itself.
In our options only 252 is the multiple of 36.
So, correct answer is option D 252
