Temperature in oven related rate

  1. Mar 18, 2009 #1
    1. The problem statement, all variables and given/known data
    A turkey is put in an oven maintained at a constant temperature of 210[tex]^{\circ}[/tex]C. At time t=30 minutes, the turkey is 135[tex]^{\circ}[/tex]C and is increasing at a rate of 1.8[tex]^{\circ}[/tex]C/minute. The model for the turkey's temperature is

    [tex]T(t) = 210 - ae^{-bt}[/tex]

    Find the values of a and b.

    2. Relevant equations

    [tex]T(t) = 210 - ae^{-bt}[/tex]

    3. The attempt at a solution

    I'm not really sure where to begin here. I could set 135deg on the left side, let t=30, and then solve for b in terms of a. Would I then use implicit differentiation to solve for a? Aren't a and b constants? Any help is much appreciated.

    is increasing at a rate of 1.8LaTeX Code: ^{\\circ} C/minute

    so dT/dt = 1.8 C/min at t= 30 mins

    Yes, a and b are constants. There's only one input: "t".
