Answer:
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.
2^1 because when you times indices you add the indices and when you divide you subtract it
Answer:
3x+y=-31
Step-by-step explanation:

Slope of perpendicular line is -3.

Sub in the point (10, -1)

The answer would be C. 73.6. If you use the correct math without rounding it would be 73.5792. Hope this helps!
