Answer:
1.5secs
Step-by-step explanation:
Given the expression that models the height as;
h(t) = -16t²+20t +6
The ball will touch the ground at when h(t) = 0
0 = -16t²+20t +6
Swap
-16t²+20t +6 = 0
Divide through by -2
8t²-10t-3 = 0
Expand using the general formula
t = -(-10)±√(-10)²-4(8)(-3)/2(8)
t = 10±√100+96/16
t = 10±√196/16
t = 10±14/16
t = 10+14/16
t = 24/16
t = 1.5
Hence it will take the ball 1.5secs to hit the ground
Answer:
47%
Step-by-step explanation:
26+27=53
100-53=47
47/100=.47
Your answer is .062 because:
.85 can't go into .05
so you see how many times it can go into .052 but it can't
so then you go to see how many times it can go into .0527
.85 times 62 is .0527
that means .85 can go into .057 62 times
