If we add the interior and the exterior of the corner of a triangle we always get 180 degree

A survey was taken of students in math classes to find

Pie

I’m guessing you meant central tendency.

I’d say the mean is the best measure for period 2. This is because it doesn’t have any extremely low or high values which could distort the mean value.

If it did ie. 8, then I would choose median as it is less affected by anomalous results

Explain and demonstrate the multiplication of complex conjugates using 2+3i and its complex conjugate. Be sure to discuss all st

krok68 [10]

The product of a complex number and its conjugate is (a + i b) · (a - i b), where a and b are real numbers, and the result for the complex number 2 + i 3 is 13.

<h3>What is the multiplication of a complex number and its conjugate</h3>

Let be a complex number a + i b, whose conjugate is a - i b. Where a and b are real numbers. The product of these two numbers is:

(a + i b) · (a - i b)

Then, we proceed to obtain the result by some algebraic handling:

a · (a + i b) + (- i b) · (a + i b)

a² + i a · b - i a · b - i² b²

a² - i² b²

a² + b²

If we know that a = 2 and b = 3, then the product of the complex number and its conjugate is:

$z\cdot \bar z = 2^{2} + 3^{2}$

$z\cdot \bar z = 13$

What is the missing term (10-4x^2)-(7x+?) =3x-6x^2

Yuliya22 [10]

Hello,

(10-4x²)-(7x+?)=3x-6x²
==>10-4x²-7x-3x+6x²=?
==>?=2x²-10x+10
