4 questions to be answered

1.) (10 pts.) Given the vectors a = ( -5, 2), b = (10, - 11), c = (0, 3), find a.) atb+ c b.) 3c - 2b c.) |c - al Show all steps. 2.) (5 pts.) Calculate the angles of the vector v = ( - 2,7) and u = (6, - 2). Round your answers to 2 decimal places. Show all steps. 3.) (5 pts.) Make a sketch of 5 different vector such that when you add them, the resultant is the zero vector. They cannot point in the same direction. You don't have to find specific vectors (like find the components). 4.) (5 pts.) Calculate the components of a vector with magnitude 8 and at an angle of 182 . Show all steps
