Previous Problem Problem List Next Problem (1 point) From the textbook: The circulation time of a mammal (that is, the average time it takes for all the blood in the body to circulate once and return to the heart) is proportional to the fourth root of the body mass of the mammal. Let the circulation time be Y and the body mass be x. (a) If an elephant of body mass 4900 kilograms has a circulation time of 132 seconds, find the constant of proportionality. Answer (b) Write a formula for the circulation time in terms of body mass. Answer: Y(x) = (c) Assume that the constant of proportionality is the same for all mammals. What is the circulation time of a human with body mass 82 kilograms? Answer: Note: You can earn partial credit on this problem. Submit Answers
