H = - 16 t² + 36 t + 10 The maximum height of the ball is at the vertex of the parabola. t = - b / 2 a t = -36/-32 t = 1.12 s The maximum height of the ball: h max = - 16 * 1.12² + 32* 1.12 + 10 = - 16 * 1.2544 + 35.84 + 10 = = - 20.0704 + 45.84 = 25.7696 = 25.77 m
B - line graph. A line graph should be added because he wants to know how many of available apartments there were during the time of the year and line graphs are usually up and down on the info.
