A ball was tossed up into the air. The height of the ball as a function of the time the ball is in the air in seconds can be modeled by a quadratic function. At the time the ball was initially thrown in the air, it was 7.5 meters off the ground. After 1.25 seconds, the ball was at its maximum height of 15.3125 meters. What was the height of the ball 2 seconds after being thrown

Someone answer asap for ! the boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a. e = 2b - 212 b. b = 2e - 212 c. e = -2b + 212 d. b = -2e + 212
