To calculate the average rate of change in the diver's depth, we can use the formula for average rate of change:
\[
\text{Average Rate of Change} = \frac{\text{Change in Depth}}{\text{Time}}.
\]
1. **Initial Depth**: The diver starts at a depth of 15 meters below the surface, which can be represented as -15 meters.
2. **Final Depth**: The diver descends to a depth of 10 meters lower than that, which is \(-15 - 10 = -25\) meters.
3. **Change in Depth**:
\[
\text{Change in Depth} = \text{Final Depth} - \text{Initial Depth} = -25 - (-15) = -25 + 15 = -10 \text{ meters}.
\]
4. **Time Taken**: The descent took 10.1 seconds.
Now we can substitute these values into our formula:
\[
\text{Average Rate of Change} = \frac{-10 \text{ meters}}{10.1 \text{ seconds}} \approx -0.99009901 \text{ meters/second}.
\]
Rounding this to the nearest hundredth:
\(-0.99\) meters/second.
So, the correct response is:
**The quotient that describes the average rate of change for the diver’s depth is negative 0.99 meters/second.**
\[
\text{Average Rate of Change} = \frac{\text{Change in Depth}}{\text{Time}}.
\]
1. **Initial Depth**: The diver starts at a depth of 15 meters below the surface, which can be represented as -15 meters.
2. **Final Depth**: The diver descends to a depth of 10 meters lower than that, which is \(-15 - 10 = -25\) meters.
3. **Change in Depth**:
\[
\text{Change in Depth} = \text{Final Depth} - \text{Initial Depth} = -25 - (-15) = -25 + 15 = -10 \text{ meters}.
\]
4. **Time Taken**: The descent took 10.1 seconds.
Now we can substitute these values into our formula:
\[
\text{Average Rate of Change} = \frac{-10 \text{ meters}}{10.1 \text{ seconds}} \approx -0.99009901 \text{ meters/second}.

Rounding this to the nearest hundredth:
\(-0.99\) meters/second.
So, the correct response is:
**The quotient that describes the average rate of change for the diver’s depth is negative 0.99 meters/second.**
