Acatapult launches a boulder with an upward velocity of 92 m/s. the height of the boulder, h, in meters after t seconds is given by the function h = -5t^2 + 92t + 16. how long does it take to reach maximum height? what is the boulder's maximum height? round to the nearest hundredth, if necessary.

What is the length of the segment joining the points at (4,5) and (6,-2) round to the nearest tenth if necessary

The length of a rectangular piece of land is 92 yards more than three times its width. the perimeter is 760 yards. find its dimensions.

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )
