Concept explainers
For Exercises 1-3, choose the correct letter.
How are the variables related on the graph?
A. as speed decreases, height stay constant
B. as speed decreases, height increases
C. as speed increases, height decreases
D. as speed increases, height increases
To relate the variables of on given graph.
Answer to Problem 3STP
D. as speed increases, height increases.
Explanation of Solution
Given information: A graph:
The horizontal axis is labeled as Speed. So the independent variable is Speed.
The vertical axis is labeled as Height. So the dependent variable is Height.
From the graph we can see that, as we move right on horizontal axis the value on vertical axis increases.
As speed increases, the height also increases at a constant rate.
Therefore, correct choice is:
D. as speed increases, height increases.
