Answer the fоllоwing questiоns. (а) Use the points P(3,1){"version":"1.1","mаth":"P(3,1)"} аnd Q(7,1){"version":"1.1","math":"Q(7,1)"} to find the vector PQ⇀{"version":"1.1","math":"PQ⇀"}. (b) Find the magnitude of the vector PQ⇀{"version":"1.1","math":"PQ⇀"}. (c) Find the unit vector of QP⇀{"version":"1.1","math":"QP⇀"}. (Caution: PQ⇀≠QP⇀{"version":"1.1","math":"PQ⇀≠QP⇀"}) (d) Express PQ⇀{"version":"1.1","math":"PQ⇀"} as the product of its magnitude and a unit vector. (You do not need to type your answers in the space below. However, you must upload a file of your handwritten work in the final question.)
