A ship carrying 1000 passengers is wrecked on a small island from which the passengers are never rescued. The natural resources of the island restrict Uthe population to a limiting value of 5780, to which the population gets closer and closer but which it never reaches. The population of the island after time t, in years, is approximated by the logistic equation given below. Complete parts (a) through (c). 5780 P()= 1+4.78e 05 a) Find the population after 10 years. 1 (Round to the nearest integer as needed. )
