To determine the rate of change in the squirrel's height above the ground, we first need to calculate the distance the squirrel travels and then divide that distance by the time it takes to travel that distance.
-
Initial Height: The squirrel starts at a perch that is 100 feet above the ground.
-
Final Height: The squirrel moves to a hole that is 45 feet above the ground.
-
Distance Traveled: \[ \text{Distance} = \text{Initial Height} - \text{Final Height} = 100 \text{ feet} - 45 \text{ feet} = 55 \text{ feet} \]
-
Time Taken: The squirrel takes 5.25 seconds to reach the hole.
-
Rate of Change: \[ \text{Rate of Change} = \frac{\text{Distance}}{\text{Time}} = \frac{-55 \text{ feet}}{5.25 \text{ seconds}} \approx -10.48 \text{ feet/second} \] The negative sign indicates that the squirrel is descending.
Thus, the quotient that describes the rate of change in the squirrel’s height above the ground is −10.48 feet/second.
