Plz help easy points Which statement is true about a nonnegative number and its additive inverse?
A. Their sum is sometimes one.
B. They are on opposite sides of zero on the number line.
C. They are always reciprocals of each other.
D. Their sum is never zero.

Dis the solution here

The correct answer is $90

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
