(a) The 9-year growth factor is the ratio of the final balance to the original balance:
74000%2F44000 = 1.6818 to 4 decimal places

(b) The 9-year percent change is the 9-year growth factor minus 1; converted to a percent:
0.6818%2A100 = 68.18%

(c) 1-year growth factor.... The 9-year growth factor is the 1-year growth factor, applied 9 times. So the 1-year growth factor is the 9-year growth factor to the 1/9 power.
1.6818%5E%281%2F9%29 = 1.0595 to 4 decimal places

(d) 1-year percent change -- see description above for 9-year percent change.
0.0595%2A100 = 5.95%
