The complex numbers corresponding to the endpoints of one diagonal of a square drawn on a complex plane are 1 + 2i and -2 – i.Wh

Musya8 [376]

On the complex plane, the number $a+bi$ is mapped onto the point with coordinates $(a,b)$ .

In other words, the x coordinate is the real part of the number, while the y coordinate is the complex part of the number.

Viceversa, if you start from a point $(x,y)$ , you can identify the number $x + iy$ .

So, the endpoints of the diagonal are the points $(1,2)$ and $(-2,-1)$ . These are points A and C in the attached figure.

This means that points B and D have coordinates

$B = (-2,2),\quad D = (1,-1)$

So, the correspondant complex numbers are

$B = (-2,2)\mapsto -2+2i,\quad D = (1,-1)\mapsto 1-i$

A "child has six blocks, three of which are red and three of which are green". How many patterns can shemake by placing them all

makvit [3.9K]

Answer: There are 20 ways and 1680 ways respectively.

Step-by-step explanation:

Since we have given that

Total number of blocks = 6

Number of red blocks = 3

Number of green blocks = 3

So, Number of patterns she can make by placing them all in a line is given by

$\dfrac{6!}{3!\times 3!}\\\\=20$

If there are 3 white blocks

so, total number of white blocks becomes 9

So, Number of total pattern she can make by placing all nine blocks in a line is given by

$\dfrac{9!}{3!\times 3!\times 3!}\\\\=1680\ ways$

Hence, there are 20 ways and 1680 ways respectively.
