What is vector w if vector v1=2i-j and vector v2=i+3j? vector w=2v1-v2 Topic: Math 1 Answer | Add Yours justaguide | College Teacher | (Level 2) Distinguished Educator Posted on August 28, 2013 at 2:27 PM The vector v1 = 2i - j, v2 = i + 3j. Vector w = 2*v1 - v2 w = 2*(2i - j) - (i + 3j) = 4i - 2j - i - 3j = 3i - 5j The required vector w is 3i - 5j We’ve answered 302,642 questions. We can answer yours, too. Ask a question
