The dye dilution method is used to measure cardiac output with 9 mg of dye, using the following formula: Cardiac output Quantity of dye To (Concentration of dye) dt The dye concentrations, in mg/ L, are modeled by c(#) - It(9 . t), 0 _ _ _ 9, where't is measured in seconds. Find the cardiac output, accurate to at least 3 decimal places. L/sec
