Step-by-step explanation:
51.90% if you sold in February, 2005 59. No. Compound
interest increase is exponential. The graph looks roughly exponen-
tial in that period, but to really tell we can compare interest
rates between marked points to see if the rate remained roughly
constant: From December 1997 to August 1999 the rate was
(16.31/3.28)12/20 − 1 = 1.6179 or 161.79%, while from August
1999 to March 2000 the rate was (33.95/16.31)12/7 − 1 = 2.5140
or 251.40%. These rates are quite different. 61. 31 years;
about $26,100 63. 2.3 years 65. a. $1510.31 b. $54,701.29
c. 23.51% 67. The function y = P(1 + r/m)mx is not a linear
function of x, but an exponential function. Thus, its graph is not a
straight line. 69. Wrong. Its growth is exponential and can be
modeled by 0.01(1.10)t
. 71. The graphs are the same because
the formulas give the same function of x; a compound-interest in-
vestment behaves as though it was being compounded once a year
at the effective rate
