The average adult takes about 12 breaths per minute. As a patient inhales, the volume of air in the lung increases. As t Datient exhales, the volume of air in the lung decreases. For t in seconds since the start of the breathing cycle, the volume of air inhaled or exhaled since r = 0 is given,¹ in hundreds of cubic centimeters, by 2n A(t)=2cos + 2. (a) How long is one breathing cycle? 5 seconds (b) Find A' (6) and explain what it means. Round your answer to three decimal places. (a) How long is one breathing cycle? 5 seconds (b) Find A'(6) and explain what it means. Round your answer to three decimal places. A'(6) ≈ 0.495 hundred cubic centimeters/second. Six seconds after the cycle begins, the patient is inhaling at a rate of A'(6)| hundred cubic centimeters/second.
