The temperature T of an object in degrees Fahrenheit after t minutes is represented by the equation
T%28t%29+=+63e%5E%28-0.0174t%29+%2B+79 where t is in minutes
the temperature of the object after 1.5 hours will be:
t=1.5h=90min

T%2890%29+=+63e%5E%28-0.0174%2A90%29+%2B+79
T%2890%29+=+63e%5E%28-1.566%29+%2B+79
T%2890%29+=+63%280.208879%29+%2B+79
T%2890%29+=+92.159377
To the nearest degree, the temperature of the object after one and a half hours is 92 degrees Fahrenheit.
