What is the rectangular form of these parametric equations: x = t + 5 and y = -3t^2

What type of function is it for the rectangular form of x = t + 5 and y = -3t^2?

• Square root

• Quartic

• Linear

• Quadratic

Eliminate the parameter and write the standard form of the parametric curve, using the Pythagorean Identity. The equations are x = 2cos(t) and y = 2sin(t), where 0 <= t <= 2pi.

Lola throws a rock with an initial velocity of 5 feet per second at an angle of (8°) above the ground. Write parametric equations to represent the path of the rock.

After 0.4 seconds, how far has the rock traveled horizontally?

Alfredo and Uriel are playing catch. Alfredo tosses a ball to Uriel at an initial velocity of 38 feet per second at an angle of (28°) from a height of 4 feet. Uriel is 40 feet away from Alfredo. Write parametric equations to represent the path of the ball.
