The function:

T(t) = 165e0.0123t

Models the temperature 7, in degrees Fahrenheit, over t minutes of a cake being taken out of the oven and placed in a 0 degree super-cooler. Which equation represents the temperature of the cake if placed in a 50-degree refrigerator?

a) T(t) = 50(165e-0.01231)

b) T(t) = 165e-0.0123t + 50

c) T(t) = 115e-0.01231 + 50

d) T(t) = 205e-0.0123t - 50

e) None of the above

Answer:

The correct option is "none of the above"

Step-by-step explanation

Given the temperature function as T(t) = 165e0.0123t when the cake is placed in a 0 degree super-cooler. For the cake to be placed in a 50 degree refrigerator will mean that 50 degrees is added to the temperature function. The temperature function therefore becomes:

T(t) = 165e0.0123t + 50

Unfortunately, this answer is not present. Which makes the option e to be correct.
