A diver descends at a rate of 8 m/min. Which expression CANNOT be used to find her depth after 5 minutes? (1 point)
−8/5
−8−8−8−8−8
−85
−8+(−8)+(−8)+(−8)+(−8)
The expression that cannot be used to find her depth after 5 minutes is −8−8−8−8−8.
The expression that CANNOT be used to find her depth after 5 minutes is:
−8+(−8)+(−8)+(−8)+(−8).
This expression represents the sum of the rate of descent (-8) for each minute (5 minutes), which would give the total depth descended. However, in this case, we are looking for the depth after 5 minutes, not the total depth descended. Therefore, this expression is not suitable for finding the diver's depth after 5 minutes.
