They are periodic functions with a period of 2π. The domain of each function is (−∞,∞) and the range is [−1,1]
Answer:
13
Step-by-step explanation:
The perimeter is all of the sides added together. Because this is a rectangle, the length and width are the same on both sides. They gave you the length and width, so just add them:
4 + 4 + 2.5 + 2.5 = 13.
So the perimeter of the shape is 13.
Answer:
"101" seems to the appropriate response. The further explanation is provided below.

Answer:
D
Step-by-step explanation:
The arcsine (
) function of x is defined as the inverse sine function of x when -1≤x≤1.
So, when
we have that
This gives us the domain 
of the function 
The range of the function 
is 
so the range of the function 
is the same (options A and C are false).
When x=-4,
So, option B is false and option D is true.
There are 3 solutions I have came up with:
