Use Laplace Tranform in solving the ff.:

After cooking for 45 minutes, when a cake is removed from an oven, its temperature is measured at 300°F. 3 minutes later, its temperature is 200°F. The oven is preheated, and so at t=0, the cake mixture is at the room temperature of 70°F. The temperature of the oven increases linearly until t=4 minutes, when the desired temperature of 300°F is attained; thereafter the oven temperature is constant 300°F for t is greater than or equal to 4 minutes.

Solve the following:

a.) devised a mathematical model for the temperature of a cake while it is inside the oven and after it is taken out of the oven.
b.) how long will it take the cake to cool of to a room temperature of 70°F?

A paint company claims their paint will be completely dry within 45 minutes after application. Recently, customers have complained drying times are longer than the claimed 45 minutes. A consumer advocate group takes a random sample of 25 paint specimens and records their drying times. The average drying time x is 49. Consider dryng time, for all test specimens, to be normally distributed with σ = 7. Suppose the claimed drying time is true, that is μ = 45 minutes,...
