Heart rates and life spans of most mammals can be modeled
Chapter 7, Problem 7.1.761(choose chapter or problem)
Heart rates and life spans of most mammals can be modeled using inverse variation. The bar graph shows the average heart rate and the average life span of five mammals. You will use the data to solve Exercises 2930. a. A mammals average life span, L, in years, varies inversely as its average heart rate, R, in beats per minute. Use the data shown for horses to write the equation that models this relationship. b. Is the inverse variation equation in part (a) an exact model or an approximate model for the data shown for lions? c. Elephants have an average heart rate of 27 beats per minute. Determine their average life span.
