Temperature at noon: Tn=-2.9 f
Rate: r=+1.3 f/h
Total decreased: d=-3.7 f
Temperature at midnight: Tm=?
Tm=Tn+r(6 p.m.-12 m)+d
Tm=-2.9 f+(1.3 f/h)(18 h-12 h)+(-3.7 f)
Tm=-2.9 f+(1.3 f/h)(6 h)-3.7 f
Tm=-2.9 f+7.8 f-3.7 f
Tm=1.2 f
Answer: T
he temperature at midnight was 1.2 f

It is determined that the temperature (in degrees Fahrenheit) on a particular summer day between 9:00a.m. and 10:00p.m. is modeled by the function f(t)=−t2+5.3t+87, where t represents hours after noon.
