Question

Can anyone help me with the question I attached below?

Answer 1

Answer:

The range in the average rate of change in temperature of the substance is from a low temperature of -22 ºF to a high of 16 ºF.

Step-by-step explanation:

Sine function is a bounded function whose range is between -1 and 1. The lowest average rate of change in temperature occurs when sine function is equal to 1 and the highest when this function is equal to -1. Then, the minimum and maximum average rate of changes in temperature are:

Minimum

$f_{min} = -19 -3$

$f_{min} = -22$

Maximum

$f_{max} = 19-3$

$f_{max} = 16$

The range in the average rate of change in temperature of the substance is from a low temperature of -22 ºF to a high of 16 ºF.
