arctic games held every 2 years. in 1970 it had 700 competitors in 2000 it had 2000. determine the ANNUAL growth rate. Helpppppppp!

• precalc11 -

2000 = 700 x^(2000-1970)

2.857 = x^30

log 2.857 = 30 log x

log x = .0151977

x = 1.0356
so
3.56 percent per year

• precalc11 -

check
700 * 1.0356^30 = 1999.99

• precalc11 -
