To show this using exponential form, you need to understand that 12 feet will be multiplied by itself three times.
12 feet x 12 feet x 12 feet = 12^3 (or 12 cubed) ft.³
The period of oscillation of a pendulum is

Where L is the length of the pendulum and

the gravitational acceleration.
Re-arranging the formula and using T=1.0 s, we find the length of the pendulum:
Answer:
37
Step-by-step explanation:
m=28+n
36=28+n
n=36-28
n=8
Annie quarters:
29+n
29+8
37
