Vector & Magnitude is (1,-9) & 9.0854 respectively! Correct option is

D) (1, -9), 182 * 9.0854

Explanation:

Here we have , We have to Identify the ordered pair that represents the vector from A(1,6) to B(2, -3) and the magnitude of AB . Let's find out:

Vector that represents from A(1,6) to B(2, -3) is given by :


AB = (2-1) i + (-3-6)j


AB = i -9j or ,


AB = (1,-9)

Now , Magnitude of vector AB is :


√((x_2-x_1)^2+(y_2-y_1)^2)


√((2-1)^2+(-3-6)^2)


√((1)^2+(-9)^2)


√(82)


9.0854

Therefore , Vector & Magnitude is (1,-9) & 9.0854 respectively! Correct option is D) (1, -9), 182 * 9.0854
