Assigmnent Scoring ature of the object is given by the numbe

Assigmnent Scoring ature of the object is given by the number of minutes after the object is placed in he room. How long (in minutes) does it take the object to reach a temperat ere m represents three decmal 1:17 PM SHIBA o o loop more Involved one-

Solution

T = 20 + 50*e^(-0.05*m)

Now

60 = 20 + 50*e^(-0.05*m)

40 = 50*e^(-0.05*m)

4/5 = e^(-0.05*m)

ln(4/5) = -0.05*m

-0.2231 = -0.05*m

m = 4.46 minutes
