Textbook Question

Chapter 6.3, Problem 107AYU

Holding Pattern An airplane is asked to slay within a holding pattern near Chicagoâ€™s O'Hare International Airport. The function $d (x) = 70 \sin (0.65 x) + 150$ represents the distance $d$ , in miles, of the airplane from the airport at lime $x$ , in minutes.

a. When the plane enters the holding pattern, $x = 0$ , how far is it from ÎŸâ€™Hare?

b. During the first 20 minutes after the plane enters the holding pattern, at what time $x$ is the plane exactly 100 miles from the airport?

c. During the first 20 minutes after the plane enters the holding pattern, at what time $x$ is the plane more than 100 miles from the airport?

d. While the plane is in the holding pattern, will it ever be within 70 miles of the airport? Why?
