Tubeworm: An article inNature reports on a study of the growth rate and life span of a marine tubeworm. 12 These tubeworms live near hydrocarbon seeps on the ocean floor and grow very slowly indeed. Collecting data for creatures at a depth of 550 meters is extremely difficult. But for tubeworms living on the Louisiana continental slope, scientists developed a model for the time T (measured in years) required for a tubeworm to reach a length of L meters. From this model the scientists concluded that this tubeworm is the longest-lived noncolonial marine invertebrate known. The model is

A tubeworm can grow to a length of 2 meters. How old is such a creature? (Round your answer to the nearest year.)
