QUESTION 2.
The local park has a rectangular flower bed that measures 10 feet by 15 feet. The caretaker
plans on doubling its area by adding a strip of uniform width around the flower bed. Determine
the width of the strip.
QUESTIONS 3.
h(t) = -4.9t2 + 8t + 5 represents Jeremiah's height (h) in meters
above the water t seconds after he leaves the diving board.
1. What is the initial height of the diving board?
2. At what time did Jeremiah reach his maximum height?
3. What was Jeremiah's maximum height?
4. How long was Jeremiah in the air?

PROBLEM SOLVING SKILLS.
REAL LIFE APPLICATION OF QUADRATIC FUNCTIONS
Throwing a ball, shooting a cannon, diving from a platform and hitting a golf ball are
all examples of situations that can be modeled by quadratic functions. In many of these
situations you will want to know the highest or lowest point of the parabola, which is known as
the vertex.
QUESTIONS |1.
A toy rocket is fired into the air from the top of a barn. Its height (h) above the ground in yards
after t seconds is given by the function
h(t) = -5t2 + 10t + 20.
1. What was the maximum height of the rocket?
2. How long was the rocket in the air before hitting the ground?
3. At what time(s) will the rocket be at a height of 22 yd?
