Presentation Transcript

  1. Let’s Review • Distributive Property • Classify Numbers • Multi-Step Equations • Absolute Value • Proportions/Percent • Inequalities • B.A.G.

  2. Unit 3 Lesson 4

  3. “I can…” • …solve equations and inequalities involving absolute value and graph their solution set on a number line • M(F&A)-10-4 • M(N&O)10-2

  4. When you combine absolute value with inequalities… • Absolute Value- the distance you are from zero on the number line • The absolute value is never negative

  5. Gyroscopes

  6. Gyroscopes…cont • To check the accuracy of one, you tilt the gyroscope platform • The ADI must indicate 10 degrees and be accurate to within 5 degrees • I checked all the helicopters here were the results. Which ones were good?

  7. Let’s Think for a minute…

  8. To account for this possibility….

  9. Example

  10. Example 1

  11. Example 2

  12. Example 3

  13. Be AWARE

  14. Other Applications • The official size or weight of sport equipment • The size or weight of bolts • The durability and strength of welds • The amount of money left in a cash register

  15. The Official size ~ 21 ounces • Must be within 1 ounce (plus or minus)

  16. Official Weight • 5.75 Ounces • Plus or minus .25 ounce

  17. An aircraft altimeter which has the current altimeter setting applied to the subscale should not have an error of more than ±50 feet when compared on the ground against a known aerodrome or runway elevation.

  18. Homework • Handout 6-5 all
