Answer:
x=6
Step-by-step explanation:
to solve this equation, we need to isolate the variable (x).
to do this we must subtract both sides by 8.
doing this we get:
4x=24
now we need to divide both sides by 4:
x=6
that's the answer!
Answer: 4 feet (approx)
Step-by-step explanation:
Since, We know that the length of pendulum,

Where L is the length of pendulum
T is the period,
And, g is the gravitational acceleration.( g=9.8
)
Here, T= 2.2 seconds
Thus, Length of pendulum,
= 1.20268570733 meter
1 meter= 3.28 ( approx)
Thus L= 1.20268570733 ×3.28 feet =3.94480912005 feet ≈4 feet
The solution is 3. The functions are inverses of each other , attached the work.
