given the points: N(-7,4) YW=(9,11), determine the unit vector of the vector WN

we can find the vector WN by subtracting the coordinates of point N from the coordinates of point W: WN = (9-(-7), 11-4) = (16, 7) To find the unit vector of the vector WN, we need to divide the vector by its magnitude. The magnitude of the vector WN can be found using the distance formula: ||WN|| = sqrt[(16)^2 + (7)^2] = sqrt(305) Therefore, the unit vector of the vector WN is: WN/||WN|| = (16/sqrt(305), 7/sqrt(305))
