The height of lava ejected from the Stromboli volcano can be modeled by the relation h= - 5t(t-11), where h is the height, in metres, of the lava above the crater and t is the time, in seconds, since it was ejected. a) Graph the scenario.
Include key information and show work below. Select an appropriate scale.

b) Find the maximum height reached by the
lava to the nearest metre.

c) How long does the lava take to reach the maximum height?

d) Is the length of time that the lava is in the air twice the answer from part c)? Explain why or why not.
