Suppose a pendulum is l meters long. the time, t,in seconds that it tales to swing back and forth once is given by t=2.01

7.236 seconds

Step-by-step explanation:

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.

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
