He saved $13.08  or 30.12%

Step-by-step explanation:

How much did Frank save in coupons

We take the original bill and subtract the final bill to determine the amount of savings

43.43 - 30.35 = 13.08

The percentage saved is

 percentage = (original - new)/ original = (43.43 - 30.35)/43.43

                                                                 = .301174303

                                                                 = 30.12%

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this
