- - - -_1,800 - - ~ P t = 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 P(0) = 1,800 interpretation of in this context?
Correct answer: B (parsed from the explanation — this source omits an answer key for this item)
Explanation
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. = 0 =1,800 Since the value of P^0h is the value of P^th when t 0, it follows that P^ h 1,800 = means that the value of P^th is 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 0 =1,800 when the study began. Therefore, the best interpretation of P^ h in this 1,800 context is the estimated number of marine mammals in the area was 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.
