Suppose that the temperature at a point x, y, z in space is given by T(x,y,z)=80/1+x2+2y2+3z2, where T=°c and x,y,z in metres. In which direction does the temperature increases fastest at the point (1,1,-2). What is the maximum rate of increase.
cup of hot chocolate is initially 170◦ F and is left in a room with an ambient temperature of 70◦ F. Suppose that at time t = 0 it is cooling at a rate of 20◦ per minute.
(a) Assume that Newton’s law of cooling applies: The rate of cooling is proportional to the difference between the current temperature and the ambient temperature. Write an initial-value problem that models the temperature of the hot chocolate.(b) How long does it take the hot chocolate to cool to a temperature of 110◦ F?
Hello, I am hung up on this problem and was hoping for help.
Thank you for your time.
We know from Newton's Law of Cooling that the rate at which an object warms
up is proportional to the difference between the ambient temperature of the
room and the temperature of the object. The differential equation corresponding
to this situation is given by y' = k(M – y) where k is a positive constant. The
solution to this equation is given by y = M + (yo – M)e-kt , where yo is the
initial temperature of the object.
Suppose your Thanksgiving turkey is kept at a temperature of 40 degrees
Fahrenheit until it is put into a 350 degree Fahrenheit oven. It takes 2 hours for
the turkey to warm up to a safe eating temperature of 165 degrees Fahrenheit.
Find the values of yo, M, and k, for this situation, rounding your answers to 3
decimal places.
Yo=
M =
k=
Regardless of your answers above, suppose the k value in this situation is
k = 0.3. Find the initial rate of increase of the turkey's temperature as soon as it
is placed in the oven. Round to 3 decimal places.
