8. 3.4 SKM & PP 8 A Chemistry Problem? In the Fahrenheit system, water freezes at 32 o F and boils at 212 o F. In the Celsius system, water freezes at 0 o C and boils at 100 o C. Using (F, C), (32 o, 0 o ), and (212 o, 100 o ) determine a formula to calculate C if F is known!

9. 3.4 SKM & PP 9 A Chemistry Problem - clues? (F, C) (32 o, 0 o ) (212 o, 100 o )

10. 3.4 SKM & PP 10 A Chemistry Problem - clues? (F, C) (32 o, 0 o ) (212 o, 100 o ) (F 1, C 1 )

11. 3.4 SKM & PP 11 Up in the Air? An ultralight crop duster is climbing at a rate of 800 ft/min. Write an equation which gives the height of the plane in terms of the time after take off. What is the height 3 minutes after take off?

12. 3.4 SKM & PP 12 Up in the Air – Clues! An ultralight crop duster is climbing at a rate of 800 ft/min.

13. 3.4 SKM & PP 13 Up in the Air – Clues! The crop duster takes off from ground level. So his height at the start is 0 feet.

14. 3.4 SKM & PP 14 Up in the Air – Clues! What is the height 3 minutes after take off? t = 3
