Determine the projection of vector w onto vector u. u=9i-6j, v=-3i-2j, w=19i+15j
Naily [24]

Answer:

proj_uw=6.2i-4.2j

Step-by-step explanation:

The projection of a vector v onto a vector u is defined as the projection of the vector v on the line that contains the vector u. It can be calculated  using the following formula:

proj_uv=\frac{u\cdot v}{||u||^2} u

Where:

u\cdot v

Is the dot product between u and v which is given by:

u\cdot v= $$\sum_{i=1}^{n} u_iv_i= u_1v_1+u_2v_2+...+u_nv_n$$

and:

||u||

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

||u||=\sqrt{u_1^2+u_2^2+...+u_n^2}

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

proj_uw=\frac{u\cdot w}{||u||^2} u

Where the dot product between u and w is:

u\cdot w =(9*19)+(-6*15)=171-90=81

And the magnitude of u is:

||u||=\sqrt{9^2+(-6)^2} = 3 \sqrt{13}

Thus:

proj_uw=\frac{u\cdot w}{||u||^2} u=\frac{81}{117} \langle9,-6\rangle=\langle6.23,-4.15\rangle\approx6.2i-4.2j

How can you use the Zero Product Property to solve quadratic<br> equations in factored form?
aniked [119]

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.

Step-by-step explanation:

I hope that helps!
