  1. Unit 9 Lesson 2

  2. Let’s Review • Mathematical Properties/classify numbers • Multi-Step Equations • Functions, Slope • Absolute Value • Proportions/Percent of increase/decrease • Inequalities : When to switch sign? • Graphing Standard/Slope-Intercept Form • Sequences, Arithmetic, Geometric • Growth and Decay • Pythagorean Theorem, Radicals • B.A.G.

  3. “I can…” • …use the position function to model the height of dropped or launched objects • M(F&A)-10-4

  4. Modeling Dropped Objects (Ft)

  5. What does this mean? • This does not show you the path of the object, but rather the height after an amount of time • The x-axis represents…

  6. Acorn Falling • If the tree is 100 feet tall… • How long does it take to hit the ground?

  7. Real life application • Drop an egg from 50 feet…

  8. Yikes!

  9. If you drop your iphone from the top… • (meters )( 3.281) = feet

  10. Modeling Launched Objects

  11. Football Punt • On 21SEP69, Steve O’Neal set a NFL record for the longest punt, 98 yards. • If a punter kicked the ball with an upward velocity at 80 ft/sec, and his foot meets the ball at 2 feet above the ground, the following function represents the HEIGHT, “y” after “t” seconds • How long was the ball in the air?

  12. A woodland jumping mouse
