Avg difficulty 2.5

Construct an equation that models the described behavior.

A spring attached to the ceiling is pulled 10 cm down from equilibrium and released. The amplitude decreases by 15% each second. The spring oscillates 18 times each second. Find a function that models the distance, D, D , the end of the spring is from equilibrium in terms of seconds, t, t , since the spring was released.
