Find the magnitude of wx for w(6 -3 6) and x(6 3 4)<br> A. 2sqrt10<br> B. 35<br> C. 4sqrt2<br> D. 32
gladu [14]

Answer:

|WX|=2\sqrt{10}

Step-by-step explanation:

To find the distance between two points in there dimensional coordinate system, we use the formula;

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2}

The magnitude for  w(6 ,-3 , 6)  and x(6, 3, 4)

|WX|=\sqrt{(6-6)^2+(3--3)^2+(4-6)^2}

|WX|=\sqrt{(0)^2+(6)^2+(-2)^2}

|WX|=\sqrt{0+36+4}

|WX|=\sqrt{40}

|WX|=2\sqrt{10}

The correct choice is A.

How to find the average squared distance between the points of the unit disk and the point (1,1)
ddd [48]
The unit disk can be parameterized by the function

\mathbf p(r,\theta)=(r\cos\theta,r\sin\theta)

where 0\le r\le 1 and 0\le\theta\le2\pi. The squared distance between any point in this region (x,y)=(r\cos\theta,r\sin\theta) and the point (1, 1) is

(x-1)^2+(y-1)^2=(r\cos\theta-1)^2+(r\sin\theta-1)^2
=(r^2\cos^2\theta-2r\cos\theta+1)+(r^2\sin^2\theta-2r\sin\theta+1)
=r^2(\cos^2\theta+\sin^2\theta)-2r(\cos\theta-\sin\theta)+2
=r^2-2r(\cos\theta-\sin\theta)+2

The average squared distance is then going to be the ratio of [the sum of all squared distances between every point in the disk and the point (1, 1)] to [the area of the disk], i.e.

\dfrac{\displaystyle\iint_{x^2+y^2
=\dfrac{\displaystyle\int_{\theta=0}^{\theta=2\pi}\int_{r=0}^{r=1}[r^2-2r(\cos\theta-\sin\theta)+2]r\,\mathrm dr\,\mathrm d\theta}{\displaystyle\int_{\theta=0}^{\theta=2\pi}\int_{r=0}^{r=1}r\,\mathrm dr\,\mathrm d\theta}
=\dfrac{\frac{5\pi}2}\pi=\dfrac52
