The quadratic model f(x)=-5x^2 +200 represents the approximate height, in meters, of a ball x seconds after being dropped. the ball is 50 meters from the ground after about how many seconds
2.45
3.16
5.48
7.07

Third option: 5.48

Step-by-step explanation:

Given the quadratic  model that represents the approximate height in meters of the ball . the time in seconds x, when the ball is 50 meters from the ground can be calculated by substituting and solving for x.

Then:

Subtract 200 from both sides:

Divide both sides by -5:

Apply square root to both sides:

The ball is 50 meters from the ground after about 5.48 seconds.

chase is right because he already been to the swings and he know how far it will be to get there
