Find d as the function of f and sketch the graph on given condition.
Answer to Problem 86E
Explanation of Solution
Given:
Let A be the point where the plane is directly above the ground.
B is the point on the ground such that the plane is perpendicular to the ground.
C is the point where the radar antenna is situated.
So here, the points A, B and C form a right-angled triangle (right angled at B).
In triangle ABC,
Ground distance of the plane from the antenna=d
Altitude of the flying plane=7 miles
Angle of elevation to the plane from the antenna=
Let consider the points to write d as function of x
Now, using
Now, plot
The above graph represents d as a function of x in the interval
