The answer is ...............47.4
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:
If your wanting to find the difference in these numbers or trying to gind the sum of them... It would be -1
Step-by-step explanation:
Answer:
PEMDAS
(5/12) +(23/10)
5/12=0.42
23/10=2.3
0.42+2.3=2.72
2.72 is the correct answer
Subtract 6x from both sides to get:
2y=-6x+12
Then divide both sides by 2 to get:
y=-3x+6
