Solve the problem.If v = 9i + 12j, find .

Solve the problem. Round your answer to the nearest tenth.Find the work done by a force of 4 pounds acting in the direction of 39° to the horizontal in moving an object 10 feet from (0, 0) to (10, 0).

Find the unit vector having the same direction as v.v = -12i + 5j

Find zw or as specified. Leave your answer in polar form.z = 6w = 12Find zw.

Decompose v into two vectors v1 and v2, where v1 is parallel to w and v2 is orthogonal to w.v = 3i + 2j,w = 3i + j
