Find the magnitude & direction of the vector jk given points . j(-6,-4) & k(-10,-4)
1 answer:
There is a formula about the distance between two points in the plane.
M(a,b) and Т(с,d)
The distance between M and N is L=sqrt[(a-c)^2+(b-d)^2)]
So the <span>magnitude of this vector is sqrt[(-6+10)^2+(-4+4)^2]=sqrt(16+0)=4
b=d This means that vector JK is</span> <span>parallel to the OX axis(there is a picture)</span>
