Answer:
The answer to your question is The second graph
Step-by-step explanation:
The general equation for a trigonometric is
Acos(Bx + C) + D
A indicates the amplitude if the value is 1, the lowest point is -1 and the highest point is 1. So we discard the first graph.
B indicates the period. A normal graph has a period of 2π, but this equation has a period of 3/2. This means that the period is smaller.
C indicates that the graph is moved to the left or right but in this problem C = 0, so it does not change.
D indicates if the graph is moved up or down, in this problem, D = 0 so it does not change.
Answer:
X could be 50 and Y could be 2 or vice versa. X and Y can also be 10.
Step-by-step explanation:
y=2+2x
Move all terms that don't contain y
to the right side and solve.

1) 85
2) 150
Step-by-step explanation:
The measure of a minor arc is EQUAL to the central angle
"The measure of a minor arc is equal to the measure of the central angle that intercepts the arc. We can also say that the measure of a minor arc is equal to the measure of the central angle that is subtended by the arc."
