alexandra is scuba diving. a diving computer automatically records her depth every five minutes. the depth readings from her first 20 minutes of diving are shown in the table below.\n| elapsed time (in minutes) | depth (in meters) |\n| ---- | ---- |\n| 0 | 0 |\n| 5 | -12.45 |\n| 10 | -9.7 |\n| 15 | -22.98 |\n| 20 | -6.6 |\nwhich best represents the greatest amount of change in her depth over a single 5 - minute period?\n-16.38 meters\n-13.28 meters\n13.28 meters\n16.38 meters
Answer
Explanation:
Step1: Calculate change for 0 - 5 minutes
Change = - 12.45 - 0=-12.45
Step2: Calculate change for 5 - 10 minutes
Change=-9.7-(-12.45)=-9.7 + 12.45 = 2.75
Step3: Calculate change for 10 - 15 minutes
Change=-22.98-(-9.7)=-22.98 + 9.7=-13.28
Step4: Calculate change for 15 - 20 minutes
Change=-6.6-(-22.98)=-6.6 + 22.98 = 16.38
Step5: Find the greatest absolute - value of changes
| - 12.45| = 12.45, |2.75| = 2.75, |-13.28| = 13.28, |16.38| = 16.38. The greatest value is 16.38.
Answer:
16.38 meters
