2) A baseball coach uses a pitching machine to simulate pop flies during practice. The quadratic function y = -16t^2 + 80t + 5 models the height in feet of the baseball after x
seconds.
When does the ball reach its maximum height?
What is the maximum height?
When does the ball hit the ground?

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry.how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.
