Question

The temperature of a cooling cup of coffee can be modelled by the equation

T = 90(0.94)", where T represents the temperature of the coffee and n is the
number of hours since it was poured. Explian what 90 and 0.94 represent in
this equation.

Answer 1

See below

Explanation:

I assume the " is n.

90 is your initial/starting temperature, in other words when n = 0 hours, the temperature will be 90.

The 0.94 part shows the rate of exponential decay.
