Answer:
The component form of the velocity of the airplane is .
Step-by-step explanation:
Let suppose that a bearing of 0 degrees corresponds with the direction and that angle is measured counterclockwise. Besides, we must know both the magnitude of velocity (), in miles per hour, and the direction of the airplane (), in sexagesimal degrees to construct the respective vector. The component form of the velocity of the airplane is equivalent to <u>a vector in rectangular form with physical units</u>, that is:
(1)
If we know that and , then the component form of the velocity of the airplane is:
The component form of the velocity of the airplane is .

Answer:
(8.49; 225°)
Step-by-step explanation:
The angle is a 3rd-quadrant angle. The reference angle will be ...
arctan(-6/-6) = 45°
In the 3rd quadrant, the angle is 45° +180° = 225°.
The magnitude of the vector to the point is its distance from the origin:
√((-6)² +(-6)²) = √(6²·2) = 6√2 ≈ 8.4859 ≈ 8.49
The polar coordinates can be written as (8.49; 225°).

<em>Additional comment</em>
My preferred form for the polar coordinates is 8.49∠225°. Most authors use some sort of notation with parentheses. If parentheses are used, I prefer a semicolon between the coordinate values so they don't get confused with an (x, y) ordered pair that uses a comma. You need to use the coordinate format that is consistent with your curriculum materials.
Answer:
a)5
b)17
c) ?
Step-by-step explanation:
Answer:
They have the same rate of change.
Step-by-step explanation:
Well the graph of Function B is y = 1 / 3x + 2
So they have the same rate of change, since they have the same slope.
