A fly-fishing line is cast in a parabolic motion with an initial velocity of 30 meters per second at an angle of 60° to the horizontal and an initial height of 1 meter. The following parametric equations represent the path of the end of the line: x(t) = (30cos(60°))t and y(t) = -9.812 + (30sin(60°))t + 1 Graph the parametric equations to complete the statements.

A. 2.6
B. 18
C. 20
D. 40
2. To the nearest tenth of a second, the end of the line reaches its maximum height after seconds.
A. 1.3
B. 2.6
C. 18.2
D. 40.0
