What conic section is drawn by the parametric equations x=csc t and y cot? A. Parabola B. Circle C. Ellipse D. Hyperbola

A biologist determines that the path of a bee from its hive to its foraging site can be described by the parametric equations x- 4t-1 and y-22+3t-4. Which of the following equations is the curve described by these parametric equations? y=20x-9 y=20x+16 x^...

A class is to eliminate t from the parametric equations x = t^2 + 3 and y = 4t. Beth says that she can write t = sqrt (x-3) to eliminate the parameter. Why is this wrong? A) She should have added 3 to x, not subtracted B) She should always solve for t as...

my answer is A

It's y= x^2+8x-25/8 y= x^2+4x-37/8 I'm sorry Reiny just need help with problems I got wrong so I can understand it
