In this sense, consider an experiment, carried out in a laboratory, in which a plant was placed in a greenhouse, where the temperature is controllable. The experiment consists of observing changes in the characteristics of this plant when subjected to temperature variations. During 24 hours, the temperature T(x) of the greenhouse varied according to the function T(x) = 20 - 10sen (π . x/4), where x is measured in hours, varying in the interval 0 ≤ x ≤ 24. During this experiment, how many times did the temperature in the greenhouse reach its minimum value? A) 1 B) 3 C) 4 D) 5 E) 7 _______________________________ Are you still unfamiliar with our EDUCATION SYSTEM? - 04 Printed Books with 3,600 pages; - Focus on ENEM and the main VESTIBULAR EXAMS in the country; - There are 10,000 questions separated by subject, topic and sub-subject; Guide for the Entrance Exam Candidate and exclusive study method.
