A ham is taken out of a 240 degrees F oven, and placed in a room that is 74 degrees F. The amount of time it takes for the ham to cool to a temperature of x degrees F is given by the equation f(x)=100 ln(78/x-74). Use the graph of the function to determine the temperature of the ham after 10 minutes. Write the equation that needs to be solved to the answer this question. Convert the equation to exponential...

A pie comes out of an oven at 325 °F and is placed to cool in a 75 °F kitchen. The temperature of the ple T (in °F) after I minutes is given by T = 75 +250e . The pie is cool enough to cut when the temperature reaches 110 °F. Determine the time this will take. Round to the nearest minute. The pie is cool enough to cut after approximately minutes

(C1HW13) A baking dish is removed from a hot oven and placed on a cooling rack. As the dish cools down to 32.0°C from 168°C, its net radiant power decreases to 11.0 W. What was the net radiant power of the baking dish when it was first removed from the oven? Assume that the temperature in the kitchen remains at 22.0°C as the dish cools.

Over a period of time, a hot object cools to the temperature of the surrounding air. This is described mathematically by Newton's Law of Cooling T=C+(To-C) e-K, where t is the time it takes for an object to cool from temperature To to temperature T, C is the surrounding air temperature, and k is a positive constant that is associated with the cooling object. A cake removed from the oven has a temperature of 210°F and is left to cool...
