Q1) vector a = (1, -2); vector b = (-3, 4). Therefore a + 2b = ... * O ( - 2, 2 ) O ( 4, -6) O (-5, 6) O (7, -10) Q2) vector a = (1, -2); vector b = (-3, 4). Therefore la - 2b| = ... * O sqrt(8) sqrt(52) O sqrt (61) O sqrt(149) Q3) vector a = (1, -2); vector b = (-3, 4); vector c = (-3, 2). c = .... * O 2a + 3b 2a - 3b 3a + 2b 3a - 2bQ4) Which two vectors may be be used to make up any vectors on the 2D plane? O (1, 1) and (-2, -2) O (1, 0) and (-1, 0) O (0, 1) and (0, 2) O (2, 0) and (0, 3) Q5) Which does NOT tell us that vector k is on the same plane as vector i and vector j? k =3i-2j O k=i-j O k= i+ j IKI = lil . lil
