Annual u. s. imports from a certain country in the years 1996 through 2003 can be approximated by
i(t) = t2 + 3.2t + 49 (1 ≤ t ≤ 9)
billion dollars, where t represents time in years since 1995. annual u. s. exports to this country in the same years can be approximated by
e(t) = 0.3t2 − 1.4t + 14 (0 ≤ t ≤ 10)
billion dollars.
assuming the trends shown in the above models continue indefinitely, numerically estimate the following. (if you need to use or –, enter infinity or –infinity, respectively. if an answer does not exist, enter dne.)
