Answer:
5.53 seconds.
Step-by-step explanation:
The equation of motion is
d = 4.9t^2 so
150 = .9 t^2
t^2 = 150 / 4.9
t^2 = 30.612
t = 5.53 seconds.
Answer:

Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation by completing the square:
Solve for x:
x^2 - 4 x + 4 = 0
Write the left hand side as a square:
(x - 2)^2 = 0
Take the square root of both sides:
x - 2 = 0
Add 2 to both sides:
Answer: x = 2
Answer:
-5x-16
Step-by-step explanation:
3 x - 8 - 8 - 8 x ?
