Question

The temperature, H, in degrees Celsius, of a cup of coffee placed on the kitchen counter is given by H = f(t), where t is in minutes since the coffee was put on the counter. (a) Is f'(t) positive or negative? (Be sure that you are able to give a reason for your answer.) (b) What are the units of f'(10)? Suppose that |f'(10)| = 1.4 and f(10) = 58. Fill in the blanks (including units where needed) and select the appropriate terms to complete the following statement about the temperature of the coffee in this case. At minutes after the coffee was put on the counter, its is and will by about in the next 30 seconds.

Problem 13. (1 point) The temperature, H, in degrees Celsius, of a cup of coffee placed on the kitchen counter is given by H = f(t), where t is in minutes since the coffee was put on the counter. (a) Is f'(t) positive or negative? (Be sure that you are able to give a reason for your answer.) (b) What are the units of f'(25)? Suppose that |f'(25)| = 1.6 and f(25) = 71. Fill in the blanks (including units where needed) and select the appropriate terms to complete the following statement about the temperature of the coffee in this case. At minutes after the coffee was put on the counter, its is and will by about in the next 15 seconds. Note: You can earn partial credit on this problem.

00:01 Hi, from the question given that the temperature h in degree celsius of a cup of coffee placed on the kitchen counter is given by h is equal to f of t where t is in minutes since the coffee was put on the counter.
00:27 So in part a we need to find if dash of t is positive or positive or positive.
00:37 Negative.
00:40 So we know that if dash of t is nothing but rate of change of temperature with respect to time t.
00:57 Here h represents the degree celsius temperature of a coffee placed on the kitchen counter where tea is calculated from the coffee was put on the counter.
01:08 So after some time, that is rate of change of the temperature will decreases.
01:13 So we conclude that f dash of t is negative.
01:23 So after time, sometimes that temperature will decreases.
01:27 Now let us move on to part b.
01:30 So for part b, we need to find the units of f dash of 10...
