Use the information on page 314 to explain how you can find the time a trampolinist spends above a certain height. Include a quadratic inequality that describes the time the performer spends more than 10 feet above the ground, and two approaches to solving this quadratic inequality.

Californian Jennifer Parilla is the only
athlete from the United States to
qualify for and compete in the
Olympic trampoline event.
Suppose the height h(t) in feet of a
trampolinist above the ground
during one bounce is modeled by
the quadratic function
h(t) = -16t2 + 42t + 3.75. We can
solve a quadratic inequality to
determine how long this performer
is more than a certain distance above
the ground
