1. a boat leaves a dock and travels along the vector $18\mathbf{i} - 3\mathbf{j}$. it then turns and travels along the vector $4\mathbf{i} + 6\mathbf{j}$. what is the resulting vector for the boats travels from the dock to its current location?

Explanation:

Step1: Sumarizar componentes i

$\vec{v}_i = 18i + 4i = 22i$

Step2: Sumar componentes j

$\vec{v}_j = -3j + 6j = 3j$

Step3: Combinar componentes

$\vec{v}_{total} = \vec{v}_i + \vec{v}_j$

Answer:

$22i + 3j$
