Para somar os vetores \( \mathbf{u} = (1, 2) \) e \( \mathbf{v} = (-2, 0) \), devemos somar as componentes correspondentes de cada vetor. 1. A primeira componente: \( 1 + (-2) = 1 - 2 = -1 \) 2. A segunda componente: \( 2 + 0 = 2 \) Portanto, a soma dos vetores é \( \mathbf{u} + \mathbf{v} = (-1, 2) \). Analisando as alternativas: a) \( \mathbf{u} + \mathbf{v} = (-1, 2) \) - Correta. b) \( \mathbf{u} + \mathbf{v} = (0, 2) \) - Incorreta. c) \( \mathbf{u} + \mathbf{v} = (1, 2) \) - Incorreta. d) \( \mathbf{u} + \mathbf{v} = (2, -1) \) - Incorreta. e) \( \mathbf{u} + \mathbf{v} = (3, 2) \) - Incorreta. A alternativa correta é a) \( \mathbf{u} + \mathbf{v} = (-1, 2) \).
