Part A: The following statements were made by 5 different students. Determine which students were correct.
Student A: The object is launched from the ground.
Student B: The flight is symmetric about the line t = 10.
Student C: The object reaches a maximum height of 12 feet.
Student D: The object is flying in the air during the interval 0 < t < 25.93.
Student E: The object reaches its maximum height after 12 seconds of flight.
Part B: The table models the flight of the objects.
Timothy said that h(4) < h(20). Do you agree or disagree with Timothy? Explain.

Answer

Part A:

  1. Student A: Correct. The graph shows the object starting at (0, 5), indicating it is launched from the ground.
  2. Student B: Incorrect. The flight is symmetric about the line t = 12, not t = 10.
  3. Student C: Incorrect. The maximum height reached is 19.4 feet, as shown at point P(12, 19.4).
  4. Student D: Correct. The object is in the air from t = 0 to t = 25.93.
  5. Student E: Correct. The maximum height is reached at t = 12 seconds.

Part B:

Timothy is incorrect. From the table, h(4) = 17.8 and h(20) = 1.3. Therefore, h(4) > h(20).
