A boat travels with velocity vector (25, 25 StartRoot 3 EndRoot). What is the directional bearing of the boat? N 30° E E 30° S E
Lina20 [59]

Answer:

The directional bearing of the boat is N 30º E

Step-by-step explanation:

Let \vec v = (25, 25\sqrt{3}), where \vec v is the vector velocity. Given that such vector is represented in rectangular, a positive value in the first component is the value of the vector in the east direction, whereas a positive value in the second component is in the north direction. The directional bearing of the boat (\theta), measured in sexagesimal degrees, is determined by trigonometrical means:

\theta = \tan^{-1}\frac{v_{y}}{v_{x}} (1)

If we know that v_{x} = 25 and v_{y} = 25\sqrt{3}, then the directional bearing of the boat is:

\theta = \tan^{-1} \sqrt{3}

\theta = 60^{\circ}

In consequence, we conclude that the direction bearing of the boat is 30 degrees to the East from the North (N 30º E).

Please help! I’m not good with y=mb+x
3241004551 [841]

Answer:

m = -4

b = -12

Step-by-step explanation:

First, identify the slope-intercept form:

y = mx + b

y = -4x - 12

Whereas m = slope and b = y-intercept.

Slope is the steepness of the line.

The y-intercept is where the line intersects the y axis.
