Pregunta: If the vector 4vec(i)+avec(k) is parallel to 5vec(i)+bvec(j)+15vec(k), find a and b.a=1,b=

To find $\mathrm{a}\text{and}\mathrm{b}$ so that the vector $4\overrightarrow{\mathrm{i}}+\mathrm{a}\overrightarrow{\mathrm{k}}$ is parallel to the vector $5\overrightarrow{\mathrm{i}}+\mathrm{b}\overrightarrow{\mathrm{j}}+15\overrightarrow{\mathrm{k}}$ , we need to know when two vectors are paral...
