Evaluate 2a + 3b if a 8 and b -1
WebAnswer (1 of 5): Consider 2a-3b ² = (2a - 3b)•(2a - 3b) = 4a² + 9b² - 12 a•b = 4 + 9 - 12(- 4), a & b are unit vectors so, a=b = 1 = 13 + 48 = 61. So, 2a-3b ... WebSubtract 3B matrix from 2A. The values of 2 A and 3 B are two matrices. The value of 2 A − 3 B can be obtained by subtracting the matrix 3 B from the matrix 2 A. 2 A − 3 B = [ 34 10 38 22 16 26] − [ 27 9 21 3 18 15] 2 A − 3 B = [ 34 − 27 10 − 9 38 − 21 22 − 3 16 − 18 26 − 15] ∴ 2 A − 3 B = [ 7 1 17 19 − 2 11]
