Answer
# Explanation:
## Step1: Define upward as positive
The rocket goes up 16.8 feet. So the change in height between the launch - point on the cliff and the distance above the cliff is best represented by a positive number.
## Step2: Define downward as negative
The rocket drops 28.1 feet from its top - height to the ocean. So the change in height from the top height of the rocket to the ocean below the cliff is best represented by a negative number.
## Step3: Write the expression
The expression to represent the change in height from the cliff to the ocean is \(16.8+( - 28.1)\).
## Step4: Calculate the result
\[16.8+( - 28.1)=16.8 - 28.1=- 11.3\]
# Answer:
The change in height between the launch point on the cliff and the distance above the cliff that the rocket reaches is best represented by a positive number. The change in height from the top height of the rocket to the ocean below the cliff is best represented by a negative number. The expression \(16.8+( - 28.1)\) best represents the change in height from the cliff to the ocean below. The change in height from the cliff to the ocean below is \(-11.3\) feet.
