The picture shows the triangle

K L M

with indicated vectors

\vec{a}

,

\vec{b}

,

\vec{c}

in a coordinate system. What are the vector coordinates

\vec{b}

? Express

\vec{b}

as a linear combination of

\vec{a}

and

\vec{c}

.

\vec{b} = (1; 3; 4.5); \vec{b} = \frac{1}{2} \vec{a} + \frac{1}{2} \vec{c}

\vec{b} = (3; 1; 4.5); \vec{b} = \vec{a} + \vec{c}

\vec{b} = (1; 3; 4.5); \vec{b} = \vec{a} + \vec{c}

\vec{b} = (3; 1; 4.5); \vec{b} = \frac{1}{2} \vec{a} + \frac{1}{2} \vec{c}
