Gi is standing on the top of a 275 feet building she throws a ball straight up into the air. the balls velocity is given as 48 ft/sec. the height, in feet, of the ball after t seconds is given by h=-16t^2+48t+275. a. how long will it take for the ball to reach its maximum height above the ground? b. what is the maximum height that the ball reaches? c. how many seconds does it take for the ball to finally hit the ground? (round answer to the nearest tenth of a second)

Which situation could best be represented by this linear equation? 24x + 38y = 520 > if x represents the number of bracelets and y represents the number of rings, there were 24 more bracelets sold than rings. the total sales were $520. if x represents the number of bracelets and y represents the number of rings, there were 38 more bracelets sold than rings. the total sales were $520. if x represents the number of bracelets sold at $24 each and y represents the number of rings sold at $38 each, the total sales were $520 if x represents the number of bracelets and y represents the number of rings, there were 520 bracelets and rings sold. bracelets were $24, and rings were $38. e
