Answer: 2.2= 11/5 or 1 1/5
Answer:

Step-by-step explanation:
The projection of a vector
onto a vector
is defined as the projection of the vector
on the line that contains the vector
. It can be calculated using the following formula:

Where:
Is the dot product between
and
which is given by:

and:

Is the magnitude of vector which can be calculated as follows:

In this sense, the projection of vector w onto vector u is:

Where the dot product between
and
is:

And the magnitude of
is:

Thus:

Answer:
The Zero Product Property states that if ab = 0, then either a = 0 or b = 0, or both a and b are 0. When the product of factors equals zero, one or more of the factors must also equal zero. Once the polynomial is factored, set each factor equal to zero and solve them separately.
