The time, in seconds, that it takes a pendulum to swing back and forth is modeled by the equation below. f (l) = 2 pi StartRoot StartFraction l Over 32 EndFraction EndRoot, where l is the length of the pendulum in feet What is the approximate length of a pendulum that takes 2.4 pi seconds to swing back and forth?

46.08 feet.

Step-by-step explanation:

Given that, for length, feet, the time period, , of the pendulum is

.

As the time period equals the time taken by the pendulum in one back and forth motion, so, actually, the given seconds to swing back and forth is the time period.

Let feet be the length of the pendulum for the time period seconds, so

[squaring on both the sides]

Hence, the approximate length of a pendulum that takes seconds to swing back and forth is 46.08 feet.

i am currently in the exact same situation rn. algebra2/adv algebra is killing

step-by-step explanation:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.
