[-/4 Points] DETAILS If a ball is thrown upward from the top of a building 224 ft high with an initial velocity of 64 ft/s, then the height h above the ground t seconds later will be h = 224 + 64t - 16t2. During what time interval will the ball be at least 32 ft above the ground? (Assume t 2 0. Enter your answer using interval notation.) [-/3 Points] DETAILS (a) Show that the lines 3x - 5y + 14 = 0 and 10x + 6y - 44 = 0 are perpendicular. slope of 3x - 5y + 14 = 0 M1 = slope of 10x + 6y - 44 = 0 m2 Since m1.m2 = , the two lines are perpendicular. (b) Find their point of intersection. ( x, y ) =
