Answer:
The answer to your question is t = 1.3 s
Step-by-step explanation:
Data
Equation h(t) = -4.9t² + v₀t + h₀
v₀ = 0 m/s
h₀ = 8 m
t = ?
h = 0 m
Process
1.- Substitute the values in the formula
0 = -4.9t² + 0t + 8
2.- Simplification
0 = -4.9t² + 8
3.- Solve for t
4.9t² = 8
t² = 8/4.9
t² = 1.63
4.- Result
t = 1.27 ≈ 1.3 s

Answer:
<h2>8.0 liters</h2>
Step-by-step explanation:
The question is not well-formatted, this is supposed to be the correct format
<em>Gavin drank 4.5 liter of water Monday before going jogging. He drank 2.3 liter of water after his jog. How much water did Gavin drink altogether? Write your answer as a mixed number.</em>
Given
we are told that he first drank 4.5 liters of water before jogging
after jogging he drank 2.3 liters
Required
Total amount of water drank
=4.5+3.5
=8.0liters
Subtract 4 from each side
Divide both sides by 5
Take square root of both sides
Add 3 to both sides
