Answer:
(a)Time taken to reach the ground, x=6 seconds
(b)Maximum height of the arrow during its flight =101.25 feet
Step-by-step explanation:
Given the quadratic function which models the flight of the arrow:
Where:
- y represents the vertical height of the arrow, in meters; and
- x represents the time, in seconds.
(a)Positive Zero
In 6 seconds, the arrow will hit the horizontal plane, i.e. the ground.
(b)
Comparing with the vertex form:
Our vertex, (h,k)=(1.5, 101.25)
Maximum Value of y=101.25
The maximum value of y represents the maximum height of the arrow during its flight, which is 101.25 feet.
