Answer:
22
Step-by-step explanation:
Start:
Beth's points = 0
Round 1:
Beth's points = -3
Round 2:
Beth's points = -3 + 28 which is 25
Round 3:
Beth's points = 25 - 3 which is 22
22
(C) sin(-r) = -a
(D) sin(r) = -a
<u>Explanation:</u>
The unit circle definition allows us to extend the domain of sine and cosine to all real numbers. The process for determining the sine/cosine of any angle θ is as follows:
Starting from (1,0) move along the unit circle in the counterclockwise direction until the angle that is formed between your position, the origin, and the positive x-axis is equal to θ.
- sin θ is equal to the y-coordinate of your point, and
- cosθ is equal to the xxx-coordinate.
In the question, sin(-r) = -a and sin(r) = -a is equal to the x-coordinate, thus they are not correct.

Sure. The point is ON the line of reflection.
9 < SQRT X < 25
If we square each term of this :
81 < x < 625 : Answer
This is what we could say for x
Hope this will help you :)
