Prove that the given argument is valid. first find the form of the argument by defining predicates and expressing the hypotheses and the conclusion using the predicates. then use the rules of inference to prove that the form is valid. (a) the domain of discourse is the set of musicians in an orchestra. everyone practices hard or plays badly (or both). someone does not practice hard. someone plays badly

bachs minuet in d minor is from the baroque period.

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

answer is : muchas/tipicas

have a nice day!
