Answer:
Therefore
, A=184
Step-by-step explanation:
Given function is

where T(t) is the temperature in °C and t is time in minute and A and k are constants.
She noticed that after 18 minutes the temperature of the pie is 138°C
Putting T(t) =138°C and t= 18 minutes


.....(1)
Again after 36 minutes it is 184°C
Putting T(t) =184°C and t= 36 minutes


.......(2)
Dividing (2) by (1)


Taking ln both sides




Putting the value k in equation (1)





⇒A= 184.
Therefore
, A=184
