Answer:

(x-3)^2 + (y+2)^2 = 9^2

Step-by-step explanation:

x^2 -6x+y^2+4y-68 = 0

Complete the square

x^2 -6x+y^2+4y-68+68 = 0+68

x^2 -6x+y^2+4y = 68

Find the term to add for x

-6 /2 = -3 -3^2 = 9

Find the term to add for y

4/2 =2 2^2 = 4

Add 9 and 4

x^2 -6x+9+y^2+4y+4 = 68+9+4

(x-3)^2 + (y+2)^2 = 81

(x-3)^2 + (y+2)^2 = 9^2

The standard form is

(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius

I’ll put you as brainiest

<h2>Answer:38.33 Kg</h2>

Step-by-step explanation:

If $mKg$ of mass is placed on spring with spring constant $k$ ,

$mg=kx$

where $g$ is universal gravitational constant

$x$ is the displacement in the spring.

In case 1:

$25g=k(0.15)\\k=\frac{25g}{0.15}$

In case 2:

$mg=k(0.23)$

Using result from case 1,

$mg=\frac{25g}{0.15}\times 0.23$

$m=$ $38.33Kg$
