When an object is thrown upwards with a speed of 64 ft/sec, its height above the ground is given by the function h(t) = -16²-642, where t is the time in seconds after it has been thrown. At what time will the object reach its highest point?

6x - 8 = 16 solve the following equation. then place the correct number in the box provided.

A, b, c, and d have the coordinates (-8, 1), (-2, 4), (-3, -1), and (-6, 5), respectively. which sentence about the points is true? a. a, b, c, and d lie on the same line. b. and are perpendicular lines. c. and are parallel lines. d. and are intersecting lines but are not perpendicular. e. and are parallel lines.

What is the slope of the line that contains the points (-2,1) and (0,-3)
