Question

P t = 1,800 1.02 t The function P gives the estimated number of marine mammals in a certain area, where t is the number of years since a study began. What is the best interpretation of P 0 = 1,800 in this context?

Accepted Answer

Choice B is correct. The function P gives the estimated number of marine mammals in a certain area, where t is the number of years since a study began. Since the value of P 0 is the value of P t when t = 0 , it follows that P 0 = 1,800 means that the value of P t is 1,800 when t = 0 . Since t is the number of years since the study began, it follows that t = 0 is 0 years since the study began, or when the study began. Therefore, the best interpretation of P 0 = 1,800 in this context is the estimated number of marine mammals in the area was 1,800 when the study began. Choice A is incorrect and may result from conceptual or calculation errors. Choice C is incorrect and may result from conceptual or calculation errors. Choice D is incorrect and may result from conceptual or calculation errors.
