Answer: -1 < x < 3</h3>
Work Shown:
| x-1 | < 2
-2 < x-1 < 2 ... see note1 below
-2+1 < x-1+1 < 2+1 ... see note2
-1 < x < 3
- Note1: use the rule that |x| < k turns into -k < x < k for some positive real number k.
- Note2: Add 1 to all sides to isolate x
Answer:
(a) 24 ft
(b) 2.5 s
Step-by-step explanation:
At t=2
h=-2(2)^{2}+10(2)+12=12+20-8=24 ft
Therefore, height after 2 s=24 ft
(b)
As it hits the ground, t is maximum and at maximum t, we differentiate the function to have
h=-4t+10 and h=0 hence
4t=10 hence t=10/4=2.5 seconds
