In completing the square method, considering the equation X^2 - 2x +  the number to be added should be<u> 1 </u>to make it a perfect square

<h3>How to know term that should added</h3>

The standard quadratic equation is of the form

ax^2 + bx + c

The completing the square method is one of the methods of solving quadratic equations

The factor to be added to the equation while using the completing the square method is of the formula

(b / 2a)^2

compared to the equation in the problem X^2 - 2x +

= (b / 2a)^2

= (2 / 2)^2

= (1)^2

= 1

What is the meaning of set?​
maw [93]

Answer:

a set is a collection of distinct objects, considered as an object in its own right. For example, the numbers 2, 4, and 6 are distinct objects when considered separately, but when they are considered collectively they form a single set of size three, written {2, 4, 6}.

</span><span>the sum is less than 8, we will remove  s which have sum of 8 or more
we have 21

the doubles  (1.1)   (2.2)  (3.3) 
So 3 out of the 21 are doubles

3/21 = 1/7

Find an equation equivalent to (x-2)^2 + (y + 2)^2 = 8 in polar coordinates
Brilliant_brown [7]

The circle equation in polar coordinates is:

   r - 4*cos(\theta) + 4*sin(\theta) = 0

<h3>How to change the coordinates of the circle equation?</h3>

Here we have the circle equation:

(x - 2)^2 + (y + 2)^2 = 8

First, we expand it to:

x^2 - 4x + 4 + y^2 + 4y + 4 = 8

Now we can rewrite it as:

x^2 + y^2 -4x + 4y + 4 + 4 = 8\\\\x^2 + y^2 - 4x + 4y = 0

Remember that:

x^2 + y^2 = r^2\\\\x = r*cos(\theta)\\y = r*sin(\theta)

Replacing that, we get:

x^2 + y^2 - 4x + 4y = 0\\\\r^2 - 4r*cos(\theta) + 4r*sin(\theta) = 0

That is the equation in polar form.

Now, because we can discard the solution r = 0, we can divide both sides by r to get:

r - 4*cos(\theta) + 4*sin(\theta) = 0

To simplify it.

PLZ HURRY IT'S URGENT!!!!!!!!!!
ICE Princess25 [194]

\:  \:  \:  \frac{9}{12} \\  =   \frac{3 \times 3}{3 \times 4} \\  =  \frac{3}{4} \\  =  \frac{3}{4} \times 1 \\  =  \frac{3}{4} \times  \frac{2}{2} \\  =  \frac{6}{8} =  \frac{3}{4}.

So, Option C is the correct answer.
