Answer:
1. 42.95
2. 8.8 meters; -14 meters
3. -53; 780
Step-by-step explanation:
1. subtract 1985 from 2013, you get 28
plug in 28 to the equation and you get 42.95
2. plug in the values of t
-4.9 (2^2) + 1.7 (2) + 25 = 8.8
-4.9 (3^2) + 1.7 (3) + 25 = -14
3. plug in your values again
5^3 - 6 (5^2) - 8 (5) + 12 = -53
12^3 - 6 (12^2) - 8 (12) + 12 = 780
