A tank holds 1,000 gallons of water, which drains from the bottom of the tank in half an hour. The values in the table show the volume V of water remaining in the tank (in gallons) after t minutes.
Step 7
To estimate the slope of the tangent line at t = 15, we average the slopes of the adjacent secant lines for t = 10 and t = 20. As obtained in part (a), those slopes are m
respectively.
sec
Therefore, the slope of the tangent line at t = 15 is as follows. (In the last step, round your answer to one decimal place.)
-136 +
If you use a graph of the function to estimate the slope of the tangent line at P(15, 1,040), you will see that it matches the above result.

Sound exerts a pressure on the human ear. This pressure P, measured in dynes per square centimeter, increases as the loudness of the sound increases. As the loudness D, measured in decibels, increases, the pressure increases by 12.2% per decibel. Furthermore, a sound of loudness 97 decibels produces a pressure of 15 dynes per square centimeter.
When the pressure on the ear reaches a level of about 200 dynes per square centimeter, physical damage can occur. What decibel level should be considered dangerous?a) 125.6 decibelsb) 119.5 decibelsc) 117.6 decibelsd) 113.9 decibels
