lionel computed the average rate of change in the depth of a pool over a two - week interval to be zero. which statement must be true?\no the pool must have been empty for the entire interval.\no the pool must have been the same depth at the start of the interval as it was at the end of the interval.\no the pool must have been deeper at the end of the interval than it was at the start of the interval.\no the pool must have been more shallow at the end of the interval than it was at the start of the interval.

Answer

Brief Explanations:

The average rate of change formula is $\frac{\text{Change in depth}}{\text{Change in time}}$. If the average rate of change is zero, it means the change in depth is zero over the time - interval. That is, the depth at the start and end of the interval is the same.

Answer:

The pool must have been the same depth at the start of the interval as it was at the end of the interval.
