5. Towns Aville and Bville are located at the points A(0,0) and B(8,4) in the plane and a waterfall is located at the point W (4, 6). There is a straight road between Aville and Bville. A tourist office wants to put up the following signs to help tourists find their way to the waterfall: two signs on the straight line from Anville to the waterfall: one at the point P₁ that is at distance 1 from A, and one at the point P₂ that is at distance 1 from W, a sign on the straight road from Anville to Bville at the point P3 that is closest to the waterfall, a sign in Bville that marks the distance to the waterfall. (a) Sketch a picture of the situation, compute vectors AB, AW and projABAW. (b) Find the coordinates of the points P₁, P2 and P3. (c) Determine the distance that needs to be written on the sign in Bville.
