For a satellite orbiting Earth, the time required to complete a single orbit is known as the period. The period P, in hours, is related to the distance D, in miles, from the center of Earth by the formula 
.
As the period increases, so does the distance. What can you say about the rate of increase in distance as period increases? A graph of D versus P can help you answer this question.
?
A. Distance increases at an increasing rate as period increases. B. Distance increases at a decreasing rate as period increases. C. A point of inflection is reached. D. None of the above.
