The situation that is best modeled by a discrete graph is: a. the daily records of the distance of each hotel from home during a cross-country trip. b. the height of a wave over time. c. the speed of a motorcycle over the distance it travels. d. the body temperature of an athlete during a workout.

Find the zeros of each function. f(x) = 6x^2 - 7x - 20

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.

How can constraints be used to model a real-world situation?
