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= 18
Explanation: you have to graph it on a grid paper first then make. Also trust me it’s the answer
It’s not the same because if you simplify them there going to end up looking different (the answers) And they get a whole different do you denominator a numerator
<span>denominator is </span>number below the line in a common fraction.
Here's picture to show what is a denominator:
2500
34420
4.59*10^9
3.442*10^4
