Answer:
(2,-3)
Step-by-step explanation:
Aside from the solution below, you can also do this without needing a coordinate plane.
When you need to move right, you know that you will be only dealing with the x-axis, so the -3 will stay the same, untouched, (x, -3)
From now on, simply add +7 to -5 and you get (2,-3)
Answer: are the required points.
or (18.124,0) and ( -6.124,0) are the required points.
Step-by-step explanation:
Let (x,0) be the point on x -axis that are 14 units from the point (6,-7) .
Then by distance formula , we have
Taking square on both the sides , we get
Using quadratic formula :
so, are the required points.
since
so, are the required points.
i.e. (18.124,0) and ( -6.124,0) are the required points.
Answer:
The bearing needed to navigate from island B to island C is approximately 38.213º.
Step-by-step explanation:
The geometrical diagram representing the statement is introduced below as attachment, and from Trigonometry we determine that bearing needed to navigate from island B to C by the Cosine Law:
(1)
Where:
- The distance from A to C, measured in miles.
- The distance from A to B, measured in miles.
- The distance from B to C, measured in miles.
- Bearing from island B to island C, measured in sexagesimal degrees.
Then, we clear the bearing angle within the equation:
(2)
If we know that ,
,
, then the bearing from island B to island C:
The bearing needed to navigate from island B to island C is approximately 38.213º.
