we can factor the whole thing:
(2sin(x) -1)(sin(x)+1) = 0.
Therefore, sin(x) = -1 and sin(x) = 1/2.
For the first one x = 3π/2 and the second is π/6 and 5π/6
So 3π/2, π/6 and 5π/6 are the solutions.
I do kind of have a problem with this because it doesn't mention if you should go over 360°. Otherwise, you have to add in an 2nπ into the equations like 3π/2 + 2nπ; 
but I don't know if that is necessary for you.
Answer:
That is incorrect. It would be appropriate if the median were 79.3, since the median is the value in the middle (when placing the data in order).
Answer:
A
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
if x=- 2 then f(x)=(-2-5)3(-2+2)=0
so x=-2 is correct
