Question

A 2005 study by the Fisheries Research Services in Aberdeen, Scotland, suggests that the average length of the species Clupea harengus (Atlantic herring) as a function of age
t
(in years) can be modeled by
L(t) = 32(1 − e−0.37t) cm
for
0 ≤ t ≤ 13.
How fast is the length changing at age
t = 6
years? (Round your answer to two decimal places.)
