Question

A loaf of bread is removed from an oven and is left setting to cool. It's temperature t minutes after being removed from the oven is given by the equation T(t)=103e^-0.0182t +73. Whatbis the temperature of the kitchen What is the initial temperature of the bread and whatbis temperature after 90 minutes

Answer 1

initial tempuratire is at t=0
T(0)=103e^0+73=103(1)+73=103+73=176 degrees

after 90 mins
T(90)=103e^-0.0182*90+72
T(90)=103e^-1.638+73
T(90)=19.6589+73
T(90)=92.6589 degrees
