The circumcenter<span> of a </span>triangle<span> is the point where the perpendicular bisectors of the sides intersect.
from the graph, we can see that the perpendicular bisector of BC is the y axis, x=0, the perpendicular bisector of AC is y=-3, so the circumcenter is (0,-3)</span>
Answer:
The directional bearing of the boat is N 30º E
Step-by-step explanation:
Let , where 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 (), measured in sexagesimal degrees, is determined by trigonometrical means:
(1)
If we know that and , then the directional bearing of the boat is:
In consequence, we conclude that the direction bearing of the boat is 30 degrees to the East from the North (N 30º E).
Slope is found when you put y2-y1/x2-x1. So your equation would be (-2)-2/6-3.
That answer would be -4/3. Nothing can be simplified further, so that is your answer
Answer: y = 9x/7 − 6/7
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
