Answer:
answer is 5
Step-by-step explanation:
First solve for theta in 'x' equation:

Substitute into 'y' equation:

Simplify by rewriting cos in terms of sine.
Using pythagorean identity:


Simplify using inverse function property:

A) True. The domain of both is: x ≥ 0
B) True. 1/2 is on the outside so it is vertical. 1/2 is between 0 and 1 so it shrinks.
C) False. the coefficient is not 2 (it is 1/2)
D) False. 1/2 is not on the inside with "x" so it is not horizontal.
Answer: A, B
