Answer:
The solution to the inequality 89 – 9.8t < 10.6 is ?
t > 8
The solution to the inequality 89 – 9.8t > 20.4 is?
t < 7
To determine when the projectile hits the ground, solve 89 – 9.8t = 0 for t.
t = 9.08163265306
Rounding to the nearest whole second, t is about ?
9 seconds.
The viable solution set is ?
[0, 7) or (8, 9]
