(a).
\Number of test aircrafts is
.
According to data collected from first test aircraft, it was
kilometers farther from Airport
than Airport
.
The two airports are
kilometers apart along the same highway, with Airport
due south of Airport
.
Distance between
airports is
kms.
The absolute value of the difference of the distances from any point on a hyperbola to the foci is
.

The two airports are foci of the hyperbola and
kilometers apart.

For hyperbola :
\
Airport
due south of Airport
so the transverse axis is vertical.
The transverse axis is vertical and the center of the hyperbola is located at the origin so the
term goes with the
term and the equation will be
.
Substitute
and
in the hyperbola equation. \ \

(b).
\Graph :
\(1).Draw the coordinate plane.
\(2).Graph the equation
.
Observe the graph :
\The plane is on top branch because it is closer to the Airport A.
\(c).
\The highway is transverse axis and the plane is
kms away from the highway.
.
Subustiute
in the equation
.

.
Therefore the coordinates of the plane are
.
(a). The equation is
.
(b). Graph of the equation
is \ \
\ \
The plane is on top branch because it is closer to the Airport A.
\(c). Coordinates of the plane are
.
