Q: Orthogonality of vectors

A.DWhich of the following sets of vectors is orthogonal? $(a)v_{1}=(2,4,-2), v_{2}=(1,4)\\ (b)v_{1}=(14,5)^{T}, v_{2}=(10,-2)^{T}\\(c)v_{1=}(5,-2,3)^{T}, v_{2}=(-2,4,6)\\(d)v_{1=}(2,3)^{T}, v_{2}=(-1,4)^{T}$ Trail: I calculated the dot products and got results of $18,130,0,10$ simultaneously. So $(c...
