HEEEEELP!!!!!! :((( help me with this exercise.

Answer:

  • See the graph attached with the vectors.

Explanation:

The exercise is to draw the corresponding vectors:

     2\vec a\\\\3\vec c\\\\3\vec d\\\\3\vec f\\\\2\vec b

Every one is the multiplication of a scalar by a vector.

The result of multiplying a scalar by a vector is a vector with the same direction of the original vector enlarged in a factor equal to the scalar magntitude.

Thus, in a graph the resulting vector is represented with a parallel arrow and pointing in the same direction as the original vector but with a length equal to the original length multiplied by the magnitude of the scalar.

For instance, the vector 2\vec a is represented with an arrow in the same direction of \vec a and with twice its length.

The figure attached contains the five requested vectors using the procedure explained above.
