Define the points P(negative 4−4,negative 2−2) and Q(33,negative 4−4). Carry out the following calculation. Find two vecto

slega [8]

Answer:

The required vectors are $u=$ and $v=$ .

Step-by-step explanation:

Given information: P(-4,-2) and Q(3,-4).

We need to find the two vectors parallel to $\overrightarrow {QP}$ with length 2.

If $A(x_1,y_1)$ and $B(x_2,y_2)$ , then

$\overrightarrow {AB}=$

$|\overrightarrow {AB}|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Using the above formula we get

vector QP is,

$\overrightarrow {QP}==$

Magnitude of vertor QP is,

$|\overrightarrow {QP}|=\sqrt{(-4-3)^2+(-2-(-4))^2}$

$|\overrightarrow {QP}|=\sqrt{(-7)^2+(2)^2}$

$|\overrightarrow {QP}|=\sqrt{49+4}$

$|\overrightarrow {QP}|=\sqrt{53}$

Using vector is

$\widehat {QP}=\frac{\overline {QP}}{|\overline {QP}|}$

$\widehat {QP}=\frac{1}{\sqrt{53}}$

$w=\widehat {QP}=\frac{1}{\sqrt{53}}$

Multiply vector w by 2 to get a parallel vector parallel of QP in same direction.

$u=2w=$

Multiply vector w by -2 to get a parallel vector parallel of QP in opposite direction.

$v=-2w=$

Therefore the required vectors are $u=$ and $v=$ .

yanalaym [24]

Answer:

It is proved

Step-by-step explanation:

A curve immersed in the three-dimensional sphere is said to be a Bertrand curve if there exists another curve and a one-to-one correspondence between and such that both curves have common principal normal geodesics at corresponding points.

What is the sum of 2/10 and 9/100

zhannawk [14.2K]

First we need to find a common denominator

$\frac{2}{10}$ = $\frac{20}{100}$
now we can add them

$\frac{20}{100}$ + $\frac{9}{100}$ = $\frac{29}{100}$
