Answer: correct answer is A 2/3x^2
Step-by-step explanation:Multiply each side of the equation by 2cos2θ to get 2rcos2θ=3sinθ.
Multiply each side of the equation by r to get 2r2cos2θ=3rsinθ. Using the relationships x=rcosθ and y=rsinθ, the equation becomes 2x2=3y.
Divide each side of the equation by 3 and reverse the order of the equation to find that y=2/3x^2
