Wilma tosses a ball into the air. The function h(t) represents the height, in feet, of the ball after t seconds. The difference quotient of h(t) is –32t – 16h + 9. What is the average rate of change in the height of the ball between 1 and 1.5 seconds? –47 ft/s –31 ft/s 31 ft/s 47 ft/s

11. a particular type of cell doubles in number every hour. which function can be used to find the number of cells present at the end of h hours if there are initially 4 of these cells? a. n = 4 ()" b. n = 4(2)" c. n = 4 + (2)" din = 4 +"

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.

Write an inequality for this description. - one fourth of the opposite of the difference of five and a number is less than twenty.
