Calculate a vector c in the same direction of the vector a and that has the same length as the vector b
Viktor [21]

For any scalar t>0, t\vec a is a vector pointing in the same direction as a.

To force this vector to have the same length as another vector \vec b, first normalize t\vec a by dividing it by its norm,

\dfrac{t\vec a}{\|t\vec a\|}=\dfrac{t\vec a}{t\|\vec a\|}=\dfrac{\vec a}{\|\vec a\|}

then multiply this vector by the norm of \vec b, so that

\vec c=\dfrac{\|\vec b\|}{\|\vec a\|}\vec a

To confirm that \vec c has the same length as \vec b:

\|\vec c\|=\left\|\dfrac{\|\vec b\|}{\|\vec a\|}\vec a\right\|=\dfrac{\|\vec b\|}{\|\vec a\|}\|\vec a\|=\|\vec b\|

What is the measure of the hypotenuse?
SVETLANKA909090 [29]

Answer:

To find the hypotenuse you need to use the Pythagorean Theorem which is

a^2+b^2=c^2

Where a and b are your two sides and c is your diagonal line

So you want to plug the numbers in for the right variables

5^2+12^2=c^2

We want to find what c equals so we are first gonna simplify

25+144=c^2

we take 5^2=25, and 12^2=144, then we add them together 25+144=169

169=c^2 now you want to take 169 and square root it because the opposite of squaring is taking it by the root square

The square root of 169=13

Your hypotenuse is 13

Hope this helps ;)

0.25 because there is 4 colours and obviously red is 0.75 percent and green and blue can’t be lower than 0.5 cuz that’s for yellow and there’s no 0%

(That makes no sense but it’s 0.25%)
