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.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
