Answer:
79 °F
Step-by-step explanation:
Newton’s Law of Cooling:
[tex]y = ae^{-kt} + c[/tex]
Data
- The initial temperature of a liquid is 160 °F
- The temperature in the room (c) is 76 °F
- Then a = 160 - 76 = 84 °F
- k = 0.23
- t = 15 minutes
Replacing into the equation:
[tex]y = 84e^{-0.23 \times 15} + 76[/tex]
y = 79 °F
Answer:
The correct answer is 78.7°F
