Answer :
The temperature at midnight is 55.4 degrees Fahrenheit
How to determine the temperature at midnight?
The information that completes the question is "At what temperature is the building at midnight?"
The function is given as:
f(t) = -8.3cos(π/5)t + 63.7
At midnight, t = 0.
So, we have:
f(0) = -8.3cos(π/5) * 0 + 63.7
Evaluate the product
f(0) = -8.3cos(0) + 63.7
Evaluate the expression
f(0) = 55.4
Hence, the temperature at midnight is 55.4 degrees Fahrenheit
