*20 pts*You drop a ball from a height of 1.5 meters. Each curved path has 74% of the height of the previous path. a. Write a rule for the sequence using centimeters. The initial height is given by the term n = 1. b. What height will the ball be at the top of the sixth path?

Question
Answer:
a.      This is the geometric sequence: a1 = 1.5 m = 150 cm, r = 0.74 The formula now is an = a1 x r ^ n-1   Just substitute a1 = 150 cm and r = 0.74 an = 150 x (0.74) ^ n – 1   b.      The second part is: A6 = 150 x 0.74 ^ 6-1 = 150 x 0.74 ^5 = 150 x 0.221906624 = 33.28509936 cm
