The vertices of square cdef are c(1, 1), d(3, 1), e(3,−1) and f(1,−1). Which of the following shows that its diagonals are congr

maks197457 [2]

The equation $-1 = -\frac {1}{1}$ shows that the diagonals are congruent perpendicular bisectors.

The vertices of the square are given as:

c = (1,1)
d = (3,1)
e =(3,-1)
f = (1,-1)

<h3>How to determine the congruent perpendicular bisectors.</h3>

Start by calculating the slope of diagonal ce using:

$m = \frac{y_2 -y_1}{x_2 -x_1}$

So, we have:

$m = \frac{-1-1}{3 -1}$

$m = \frac{-2}{2}$

$m_1 = -1$

Next, calculate the slope of diagonal df using:

$m = \frac{y_2 -y_1}{x_2 -x_1}$

So, we have:

$m = \frac{-1-1}{1-3}$

$m = \frac{-2}{-2}$

$m_2 = 1$

The slopes of both diagonals are:

$m_1 = -1$

$m_2 = 1$

By comparing both slopes, we have:

$m_1 = -\frac {1}{m_2}$

i.e.

$-1 = -\frac {1}{1}$

Hence, $-1 = -\frac {1}{1}$ shows that the diagonals are congruent perpendicular bisectors.

What is the sum of the complex numbers 6+2i and 3+5i, where i=sqrt(-1)

m_a_m_a [10]

Answer:

The sum of the complex numbers is $9+i\,7$ .

Explanation:

Let be $u = 6 + i\,2$ and $v = 3 + i\,5$ , the sum of the complex number can be found by algebraic means. That is:

1) $u = 6 + i\,2$ , $v = 3 + i\,5$ Given.

2) $u+v = (6+i\,2)+(3+i\,5)$ Definition of addition.

3) $u+v = (6+3) + (2\,i + 5\,i)$ Commutative and associative properties.

4) $u+v = 9 + (2+5)\,i$ Definition of addition/Distributive property.

5) $u + v = 9 + i\,7$ Definition of addition/Commutative property/Result.

The sum of the complex numbers is $9+i\,7$ .
