g A plane flying horizontally at an altitude of 2 miles and a speed of 550 mi/h passes directly over a radar station. Find the rate at which the distance from the plane to the station is increasing when it is 5 miles away from the station. (Round your answer to the nearest whole number.)

The rate at which the distance from the plane to the station is increasing is when it is 5 miles away from the station is 504 mi/h

Step-by-step explanation:

An illustrative diagram for the scenario is shown in the attachment below.

In the diagram, y represent the altitude, z is the horizontal distance from the plane to the station and x is the distance from the plane to the station.

From the Pythagorean theorem, we can write that

x² = y² + z²

Differentiate this with respect to time t

That is,

=

The rate at which the distance from the plane to the station is increasing is

is the rate at which the altitude is increasing, since the altitude is 2, that is constant, .

is the rate at which the horizontal distance is increasing which is the speed, that is,

and

Now, we will determine z when x = 5.

From x² = y² + z²

5² = 2² + z²

25 = 4 + z²

z² = 25-4

z² = 21

z =√21

Putting all the values into the equation

Hence, the rate at which the distance from the plane to the station is increasing is when it is 5 miles away from the station is 504 mi/h.

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
