Exploring Non-linear Word Problems in Section 5.2.2

The lesson covers practice problems involving word problems and parabolas. It describes a scenario where Jamal and Dinah accidentally throw food at Harold, leading to a mathematical problem involving parabolas. Students are guided to solve the problem graphically and algebraically to determine Harold's height. The lesson concludes with additional tasks for students.

What event caused Jamal and Dinah to drop their food?

• They tripped over a book on the floor.

• They were running late to class.

• They were playing a game.

• They were distracted by Harold's dance moves.

How high did Jamal's cupcake fly?

• 12 feet

• 24 feet

• 9 feet

• 6 feet

What is the vertex of the parabola for Jamal's cupcake?

• (10, 9)

• (20, 0)

• (24, 6)

• (0, 0)

What is the vertex of the parabola for Dinah's sandwich?

• (12, 6)

• (10, 9)

• (0, 0)

• (24, 0)

What is the general form of the equation for a parabola?

• y = mx + b

• y = ax^2 + bx + c

• y = a(x - h)^2 + k

• y = a(x + h)^2 + k

What values are substituted for h and k in the equation for Jamal's cupcake?

• h = 12, k = 6

• h = 0, k = 0

• h = 20, k = 0

• h = 10, k = 9
