  1. Word Problems With Quadratics

  2. The height of a ball thrown straight up from 3m above the ground is modeled by h = -5t² + 14t + 3 • After how long will the ball hit the ground? • What is the maximum height of the ball?

  3. The price for a new bicycle that is being developed is modeled by P = C² - 460C + 42000 • What are the prices where the shop owners would sell no bikes? • What is the ideal price to sell the most bikes?

  4. The sum of two numbers is 27 and their product is 50. What are the two numbers?

  6. A ball is thrown upwards from a rooftop, 80m above the ground. It will reach a maximum vertical height and then fall back to the ground. The height of the ball from the ground at time t is h, which is given by,h = -16t2 + 64t + 80. • What is the height reached by the ball after 1 second? • What is the maximum height reached by the ball? • How long will it take before hitting the ground?

  7. A ball is shot from a cannon into the air with an upward velocity of 40 ft/sec. The equation that gives the height (h) of the ball at any time (t) is: h(t)= -16t2 + 40ft + 1.5.  • How long does it take the ball to reach a height of 20 feet?

  8. Tommy’s Custom T-Shirts produces t-shirts with customized logos. The company’s annual profit is modelled by P = -6t² + 60t + 234, where t represents the number of dozens of t-shirts produced, in thousands. • How many t-shirts does the company need to produce to break even?

  9. A ball thrown from the top of a building follows the path h = -5(t + 2)((t – 7) • How tall is the building?
