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
You set the corresponding sides equal to each other and solve for x as you would in a normal equation
Answer:
Step-by-step explanation:
The correct answer of this question is B
All you need is multiply it by 6
The answer is D because you could use the equation y=mx+b and replace the numbers
If i read this correctly it should be $90. 10x5= $50 and that plus $40 equals $90 altogether
