That is when h=0
so assuming yo meant
h(t)=-16t²+24t+16
solve for t such that h(t)=0
because when height=0, the gymnast hits the ground
so
0=-16t²+24t+16
using math (imma complete the square
0=-16(t²-3/2t)+16
0=-16(t²-3/2t+9/16-9/16)+16
0=-16((t-3/4)²-9/16)+16
0=-16(t-3/4)²+9+16
0=-16(t-3/4)²+25
-25=-16(t-3/4)²
25/16=(t-3/4)²
sqrt both sides
+/-5/4=t-3/4
3/4+/-5/4=t
if we do plus (because minus would give us negative height)
8/4=t
2=t
it takes 2 seconds
Answer:
13
Step-by-step explanation:
We replace each X with a 3, so
4 + 3 + 3 + 3
which equals to 13
Answer is 8 liters
Reason
1 to 4 is the same as 2 to 8
So 2 concentrate to 8 water
5.5x+9

The first thing you do is you divide the annual interest
into 12 months
4.8 % / 12
Make sure that you convert the interest
So 0.048/12
Then you get the interest last month so that is
2.25/ (0.048/12)
The answer is 562.5
B.$562.5
