The equation 6600 200- R(Y) R(V) = can be used to determine the heart rate, R, of a person whose heart pumps 6600 milliliters (mL) of blood per minute and v milliliters of blood per beat. Complete parts a) through c) below Heart rate 100- 100 200 Output per beat a) Find the rate of change of heart rate with respect to v, the output per beat R'(V)= b) Find the heart rate at v = 70 mL per beat The heart rate is beats/min. (Round to two decimal places as needed.) c) Find the rate of change at v = 70 mL per beat. The rate of change is beats/min per ml (Round to two decimal places as needed.) Time Remain
