Make a table of values for each set of parametric equations, graph the equations, and include an orientation; then write the Cartesian equation.
A ball is launched with an initial velocity of 80 feet per second at an angle of 40° to the horizontal. The ball is released at a height of 4 feet above the ground.
- ⓐ Find the parametric equations to model the path of the ball.
- ⓑ Where is the ball after 3 seconds?
- ⓒ How long is the ball in the air?
