A ball is thrown upwards from a bridge into a river below. The height of the ball above the water, in meters, can be modelled by the quadratic equation , where  is the time in seconds since the ball was thrown. Determine at what time(s) is the ball  meters above the water. Interpret the solutions.

New Question) 1 ptsGroup of answer choicesA linear trendline would be a better fit for representing the relationship between time and height.At 10 seconds the height of the ball is about 710 meters above the ground.The height of the ball at 20 seconds will be negative thus we can assume it will be underground.Higher balls cause an increase in the time in seconds.

Jen served the final point before winning her tennis match! She tossed the ball up into the air from a height of 5 feet with a velocity of 22 feet per second. After the ball started to come back down, Jen hit the ball with her racket at a height of 6 feet.Which equation can you use to find how many seconds the ball was in the air before Jen hit it?If an object travels upward at a velocity of v feet per second from s feet above the ground, the object's height in feet, h, after t seconds can be modeled by the formula h=–16t2+vt+s.6=–16t2+22t+55=–16t2+22t+6To the nearest tenth of a second, how long was the ball in the air before Jen hit it? seconds

A water fountain is designed to shoot a stream of water in the shape of a parabolic arc. The equation of the parabola is given by ℎ(𝑡)=−0.5𝑡2+4𝑡+1h(t)=−0.5t 2 +4t+1, where ℎ(𝑡)h(t) represents the height of the water stream in meters and t  represents the time in seconds since the water was shot. Answer the following questions.Determine the maximum height reached (in meters).

A ball is thrown vertically upwards. Assuming the air resistance to be constant and considerable :–the time of ascent ≥ the time of descentthe time of ascent < the time of descentthe time of ascent > the time of descentthe time of ascent = the time of descent

h=−4.9t 2 +25tThe equation above expresses the approximate height ℎ, in meters, of a ball 𝑡𝑡 seconds after it is launched vertically upward from the ground with an initial velocity of 25 meters per second. After approximately how many seconds will the ball hit the ground?A3.5B4.0C4.5D5.0
