A person sitting in the top row of the bleachers at a sporting event drops a pair of sunglasses from a height of 24 feet. The function: h = -16x² + 24 represents the height h (in feet) of the sunglasses after x seconds. How long does it take the sunglasses to hit the ground? Please explain all of your steps. Your explanation should be good enough for a friend that missed the lesson. Pretend like you are teaching it to them.

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.
