Answer:
after 10 seconds
Step-by-step explanation:
h=-16t^2+v0*t+h0
ground level is h0 with a measure of 0
160 is v or velocity
0=-16t^(2)+160t+0
0=-16t^(2)+160t
0=16t(-t+10)
0/16t=(-t+10)
0=-t+10
-10=-t
10=t
t=10
1.) 3 (3t + s)
distribute
9t + 3s
plug in the variables
9 ( 12 ) + 3 ( 9 )
108 + 27
135
2.) 2s - t
plug in the variables
2 ( 9 ) - 12
18 - 12
6
I hope this helped and i sincerely hope that this was the brainliest answer!
have a nice day
Where is the graph or information to solve this question
5/12 is the sum of 1/4 + 1/6
Add all number then subtract by how many numbers you added together
1) add --- 14.4 + 13.6 + 11.3 = 39.3
2) you added three numbers together so dived by 3 --- 39.3 / 3 = 13.1 pounds
