When you multiply a pair of conjugates you get a real number

1 answer:

4 0

Answer: The complex conjugate has a very special property. Consider what happens when we multiply a complex number by its complex conjugate. We find that the answer is a purely real number it has no imaginary part. This always happens when a complex number is multiplied by its conjugate the result is real number.

Real numbers can be positive or negative, and include the number zero. They are called real numbers because they are not imaginary, which is a different system of numbers

Step-by-step explanation: Every complex number has a complex conjugate. The complex conjugate of a + bi is a - bi. For example, the conjugate of 3 + 15i is 3 - 15i, and the conjugate of 5 - 6i is 5 + 6i.

Given: rectangle ABCD is similar to rectangle ZBXY. If BC = 10, BX = 6, XY = 4, then CD =

maksim [4K]

Answer:

$CD=6\frac{2}{3}\ units$

Step-by-step explanation:

we know that

If rectangle ABCD is similar to rectangle ZBXY

then

the ratio of their corresponding sides is equal and is called the scale factor

$\frac{BC}{BX}=\frac{CD}{XY}$

in this problem we have

$BC=10\ units$

$BX=6\ units$

$XY=4\ units$

Substitute the values and solve for CD

$\frac{10}{6}=\frac{CD}{4}$

$CD=4*10/6$

$CD=20/3=6\frac{2}{3}\ units$

The equation that can be used to find the length of the tank is 240 = l × 12 × 10

<h3>How to find the volume of rectangular prism?</h3>

The volume of a rectangular prism can be found as follows:

volume of rectangular prism = lwh

where

l = length
w = width
h = height

Therefore,

volume of rectangular prism = lwh

volume of rectangular prism = 240 ft³

h = 12 ft

w = 10 ft

Therefore, the let's find the length of the tank.

240 = l × 12 × 10

240 = 120l

divide both sides by 120

l = 240 / 120

l = 2

Y=mx+c where m is the gradient.
If the equation is perpendicular is - $\frac{3}{4}$

Use y-y1=m(x-x1)
and you should get
y+1=- $\frac{3}{4}$ (x+4)
4y+4=-3x-12
y=-<span> $\frac{3}{4}$ </span>x - 16
