He wants to plant squash, pumpkins, corn, beans, and potatoes. His plan for the field layout in feet is shown in the figure below. Use the figure and your knowledge of polynomials, perimeter, and area to solve the following: 1. Write and simplify an expression that represents the length of the south side of the field. 2. Write and simplify a polynomial expression that represents the perimeter of the pumpkin field.
3. Write and simplify a polynomial expression that represents the area of the potato field. 4. Write and simplify the polynomial expression that represents the area of the bean field if x = 3 and y = 7. What unit would the area of Bob s bean field have? Application of Quadratic Functions Click on the Link to watch the video --> Punkin Chunkin How long does a Projectile Pumpkin stay in the air? Directions: Watch the video and follow along to solve a problem that will tell us how long a Projectile Pumpkin will stay in the air. Answer the following questions as you go along. You may pause and re-watch the video as necessary. When you have finished the video and the related problem, see if you can use your skills to solve an additional pumpkin related problems. Problem 1: The graph of a Projectile Pumpkin may look like the graph below. The projectile s height over time can be described by the following quadratic equation where h = height and t = time. h = -16t 2 + 76t + 20
Based on the video and using the equation above, can you answer the following questions about the equation: 1. What is the initial velocity (related to the acceleration of gravity) of the pumpkin? 2. What is the initial upward velocity? 3. What is the initial height? 4. How long will the pumpkin stay in the air? To do this we must find the zero(s) or root(s) or solution(s) by FACTORING (Follow along with the video) Step 1 : Multiply by -1 Step 2: Divide by 4 Step 3: Ready to Factor ( t )( t ) = 0 Step 4: Set each Factor equal to zero and solve Step 5 : Using your answer from Step 4, Answer the Question How long does the pumpkin stay in the air before hitting the ground? Problem 2: 1: What is the maximum height the pumpkin reaches? 2: At what time does the pumpkin reach it s maximum height?
Problem 3: A pumpkin is launched from a catapult that is located at the top of a building that is 128 feet above the ground. The pumpkins height can be calculated after t seconds by the following Equation: h = -16t 2 + 32t + 128 How long will the pumpkin stay in the air? Factor the quadratic equation and solve.
