An airplane needs to head due north, but there is a wind blowing from the northeast at 50 km/hr. the plane flies at an airspeed of 700 km/hr, to end up due north, the pilot will need to fly the plane preview degrees east of north.

Step-by-step explanation:

Using vector method to solve it

Resultant can be given by

R=671.12 Km/hr

The angle made by resultant with 700 km/hr is

using sine rule

step-by-step explanation:

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola
