An airplane flies horizontally from east to west at 280280 mi/hr relative to the air. if it flies in a steady 3030 mi/hr wind that blows horizontally toward the southwest (45degrees° south of west), find the speed and direction of the airplane relative to the ground.

We can find for the new speed of the plane using the cosine law. Let us say that the new speed is c:

c^2 = 280^2 + 30^2 – 2(280)(30) cos (90°+45°)

c = 302 mi/hr

The angle relative to the ground is calculated using sine law:

sin C / 30 = sin (90+45) / 302

C = 4.03°

The new speed is 302 mi/hr at -4.03° relative to the ground.

step-by-step explanation:

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
