On the first swing, a pendulum swings through an arc of length
60 cm. On each successive swing, the length of the arc is 80%
of the length of the previous swing.

1.) Write a rule to model this situation. formula: A(n)=a•r^n-1

2.) Find the length of the arc on the 5th swing. Round answer to the nearest tenth please! :)

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
