^2 m t = –0.0274 +7.3873 +75.032 () t/7 t/7 m(t) The function m gives the predicted body mass, in kilograms (kg), of a certain animal t days after it t ≤ 390 was born in a wildlife reserve, where. Which of the following is the best interpretation of the m(330) statement “ is approximately equal to 362” in this context?
Correct answer: B (parsed from the explanation — this source omits an answer key for this item)
Explanation
330 362 Choice B is correct. In the statement “m^ h is approximately equal to ,” the 330 input of the function, , is the value of t, the elapsed time, in days, since the 362 animal was born. The approximate value of the function, , is the predicted body mass, in kilograms, of the animal after that time has elapsed. Therefore, the 362kg 330 predicted body mass of the animal was approximately days after it was born. Choice A is incorrect. This would be the best interpretation of the statement 362 330 330 “m^ h is approximately equal to .” Choice C is incorrect. The number 7 is the number of weeks, not the number of days, after the animal was born. Choice D 362 is incorrect. This would be the best interpretation of the statement “m^ h is 330 approximately equal to 7 .”
