Answer:
The object's temperature after 18 minutes is of 426ºC.
Step-by-step explanation:
The temperature after t minutes is modeled by an exponential function, which has the following format:

In which T(0) is the initial temperature, and r is the cooling rate, as a decimal.
Its initial temperature is 730°C and it cools at a rate of 2.95% per minute
This means that
. So



Find the object's temperature after 18.0 minutes.
This is
. So


The object's temperature after 18 minutes is of 426ºC.
If you are asking how to estimate it would be right.
