Ответ:
2. The axis of symmetry of the graph is x equals 7.5
3. The has a relative maximum at (7.5,56.25)
Ответ:
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)
