Newton's Law of Cooling says that a hot object cools rapidly when the difference between its temperature and that of the surrounding air is large, but the object cools more slowly when it nears room temperature. Suppose a piece of aluminum is removed from an oven and left to cool. The following table gives the temperature
a. Explain the meaning of
b. Find the average decrease of temperature pet minute during the first half-hour of cooling.

c. Find the average decrease per minute of temperature during the first half of the second hour of cooling.
d. Explain how parts b and c support Newton's law of cooling.
e. Use functional notation to express the temperature of the aluminum after I hour and 13 minutes. Estimate the temperature at that time. (Note: Your work in part c should be helpful.)
f. What is the temperature of the oven? Exams your answer using functional notation, and give its value.
g. Explain why you would expect the function A to have a limiting value.
h. What is roan temperature? Explain your reasoning.

- Define Newton’s Law of Cooling. Then name at least three real-world situations where Newton’s Law of Cooling would be applied.arrow_forwardA bottle of soda with a temperature of 71 Fahrenheit was taken off a shelf and placed ina refrigerator with an internal temperature of 35 .After ten minutes, the internal temperature of thesoda was 63F . Use Newton’s Law of cooling towrite a formula that models this situation. To thenearest degree, what will the temperature of thesoda be after one hour?arrow_forwardA 500-mg dose of a drug is administered by rapid injection to a patient. The half-life of the drug is 9 hours. a. Find a model for the amount of drug in the bloodstream t hours after the drug is administered. b. Find the average rate of change of drug in the bloodstream between t=0 and t=2. Repeat for t=9 and t=11.arrow_forward
