Unformatted text preview: . Solving the rst equation For KX we arrive at KX = ln 34 . 5 16 21 = 0 . 12675 . (3.8) Substituting this value into the second equation we, can solve For K as Follows: 33 . 7 = 16 + 21 e . 12675 K K = . 12675 + ln 33 . 7 16 21 = 0 . 04421 . This results in an equation For the body temperature oF T ( t ) = 16 + 21 e . 04421 t . rom equation (3.8) we now nd the number oF hours X beFore 12 Noon when the person died. X = . 12675 K = . 12675 . 04421 2 . 867 (hours) . ThereFore, the time oF death is 2 . 867 hours (2 hours and 52 min) beFore Noon or 9 : 08 a.m. 118...
