Question

the following graph shows the height,in feet,over time,in seconds,of a bottle rocket that was launched from the ground. Which of the following are true? Select all that apply

Answer 1

1.The bottle rocket reached a maximum height of 56.25 feet
2. The axis of symmetry of the graph is x equals 7.5
3. The has a relative maximum at (7.5,56.25)

Answer 2

Answer:

OPtion 1,3 and 5 are only correct

Step-by-step explanation:

Given is a graph showing the height on y axis and time on x axis.

We find that initially starting from 0, it reaches maximum at 7.5 seconds to a height of 56.25 feet

Then comes down to the ground after 15 seconds

The parabola shape has vertex at (7.5,56.25)

Hence symmetrical about x=7.5. Not one solution because we find that when height =0, t takes two values as 0 and 15.

OPtion 1,3 and 5 are only correct

1) The bottle rocket reaches the maximum at 56.25 feet

ii) Axis of symmetry is x=7.5

iii) Relative maximum at (7.5,56.25)
