Question 62067: A frozen turkey is placed in an oven preheated to a temperature of 425 degrees F. The temperature of the inside of the turkey after t minutes is given by M(t)=425(1-e^-kt), where k is a constant. The value of k is 0.047. How long will it take the inside of the turkey to reach a temperature of 400 degrees?

Question 62064: I have no idea how to work this problem, could someone help me?
In an amplifier, the power gain P is given by the function:
P= 10 log Pout/Pin
where Pin is the power input in watts and Pout is the power output in watts. If an amplififier has a power gain of 10 watts and the output power is 7 watts, find the input power.
(added note the out and in words next to the P are suppose to be lower than the P, but I don't know how to show it on here. so it would be the opposite of using the ^ sign to do what I mean.)
