3. True or false? All vectors below are in Rⁿ for some n. If your answer is “True”, explain why. If your answer is “False”, give a counterexample. Please specify for all if the given statement is true or false, thank you!

(1) If two vectors are linearly independent, then they are orthogonal.

(2) If x is orthogonal to both u and v, then x must be orthogonal to u − v.

(3) If W is a subspace of Rⁿ, then W and W^⊥(W transpose) have no vectors in common.

(4) If z is orthogonal to v₁ and v₂ and if W =span(v₁,v₂), the z must be in W^⊥(W transpose) .

(5) ∥cv∥ = c∥v∥ for all scalars c and vectors v in Rⁿ .
