The problem states the pendulum is 12.96 meters long
The formula I have is
time = 2 • π * sq root [ length (meters) / g ] where g = 9.81
time = 6.283 * sq root (12.96 / 9.81)
time = 6.283 * sq root (1.321)
time = 6.283 * 1.149
time = 7.222 seconds
It is given that a pendulum is L meters long. The time,t,in seconds that it tales to swing back and forth once is given by
We need to find the time taken by pendulum to swing back and forth once if the length of the pendulum is 12.96 meters.
Substitute L=12.96 in the given equation.
Therefore, the time taken by pendulum to swing back and forth once is 7.236 seconds.
5(x + 8)
7x - 49
7(x - 7)
18x + 9
9(2x + 1)
15x - 10
5(3x - 2)
for number one all you have to do is factor 5 out of 5x + 40
for number 2 factor 7 out of 7x - 49
for number three factor 9 out of 18x + 9
for number four factor 5 out of 15x - 10
no this is a nonlinear negative
