To sketch the vector
, we can plot it on a coordinate plane. The vector starts at the origin (0,0) and ends at the point (3,-3).To find the magnitude of the vector
, we can use the formula for the magnitude of a vector in two dimensions:
where
and
are the components of the vector.In this case,
and
. Plugging these values into the formula, we get:
Therefore, the magnitude of the vector
is
.To sketch the vector
, we can plot it on a coordinate plane. The vector starts at the origin (0,0) and ends at the point (3,1).To find the magnitude of the vector
, we can use the same formula for the magnitude of a vector in two dimensions:
In this case,
and
. Plugging these values into the formula, we get:
Therefore, the magnitude of the vector
is
.
