Find the center and radius of the circle

Wewaii [24]

<h2>AnswEr :</h2>

Provided Equation

x² + y² - 6x + 4y + 4= 0

As we know the Standard Equation of a Circle is

$\bf{(x - a)} {}^{2} + (y - b) {}^{2} = {r}^{2}$

where,

r radius of circle.

(a,b) centre .

$\implies \sf \: {x}^{2} + {y}^{2} - 6x + 4y + 4 = 0$

This equation can be further written as

$\implies \sf \: {x}^{2} - 6x + {y}^{2} + 4y = - 4$

Now completing the square ( by adding 4 & 9 on both side ) .

$\implies \sf \: {x}^{2} - 6x + 9 + {y}^{2} + 4y + 4 = - 4 + 9 + 4$

again this equation can be further written as

$\implies \sf \: (x - 3) {}^{2} + (y + 2) {}^{2} = {3}^{2}$

Now comparing this equation with standard equation of circle ( mentioned above) and we will get

Centre = ( a,b) = (3, -2 )
Radius = r = 3

Therefore,

Centre of circle is (3,-2) and radius is 3

Find the 7 term of the Gb 2 , -6 , 18

Maslowich

Answer:

Step-by-step explanation:

For a geometric sequence

U(n) = ar^n - 1

Where

n is the number of terms

r is the common ratio

a is the first term

From the sequence

a = 2

r = - 6 /2 = -3

U(n) = 2(-3) ^ n - 1

For the 7th term

U(7) = 2(-3) ^ 7 - 1

= 2(-3)^6

The final answer is

= 1458

Hope this helps you
