Which of the following points could be the initial point of vector v if it has a magnitude of 10 and the terminal point (-2,4)? a. (-0.2, 0.4) b. (-8, -4) c. (-12, -6) d. (1, 3)

The initial point is (-8, -4)

Step-by-step explanation:

Given that the terminal point is (-2,4) and the magnitude of vector v is 10 then we have to find the initial point.

Let the initial point is (x, y).

The point which satisfy the above condition is the initial point

Option a: (-0.2, 0.4)

Not satisfied

Option b: (-8, -4)

Satisfied

Option c: (-12, -6)

Not satisfied

Option d: (1, 3)

Not satisfied

Hence, option 2 is correct.

The initial point is (-8, -4)

answer is x<
