Answer: 76
Step-by-step explanation: 29 + 47
Given,
2x - 1/2 = 3 - x
2x + x = 3 + 1/2
3x = 7/2
3x = 3.5
x = 3.5/3
x = 1.167
22/x=9/100
22*100=9x
2200=9x
2200/9=x
244.4
we are given
(a)
we can plug t=0
so, the height above the ground when the object is launched is 60 meter......Answer
(b)
we can set s(t)=0
and then we can solve for t
we can use quadratic formula
we get
..........Answer
(c)
we can find vertex
t=2.040816
now, we can plug it back
so, the maximum height is 80.408meter.........Answer
