Eliminate the parameter x=4+2 cos∅ y=1+2 sin∅ I think i can solve it like this but i am not sure x=4+2cos∅ x-2=4cos∅ x-2/4=cos∅

Write the rectangular form for the parametric equation x=cosθ ; y=4sinθ

I understand parametric equations for the most part, but i always have trouble with finding their intersection points. I would be glad for a second opinion. Thanks so much!

What are the steps?

A baseball is pitched horizontally at 95 mph, or about 140 feet per second. How long does it take for the ball to reach the batter at home plate, which is about 60 feet from the mound? Parametric...

I have the answers {x=2t, y=(1/8t^3) } and {x=t, y=(1/t^3)} If I have the wrong answers could you explain how to get the right ones? I have to answer this in class tomorrow and I'm insanely paranoid...
