Question
Employers are increasingly turning to GPS (global positioning system)
technology to keep track of their fleet vehicles. The estimated number of
automatic vehicle trackers installed on fleet vehicles in the United States is
approximated by
N(t) = 0.66e0.23t
(0 st< 9)
where N(t) is measured in millions and t is measured in years, with t = 0
corresponding to the year 2000.
(a) What was the number (in millions) of automatic vehicle trackers installed in
the year 2000? How many were projected to be installed in 2003? (Round
your answers to two decimal places.)
