Find the center and the radius of the circle with the equation:x^2+6x+y^2+4y+12=0
oksian1 [2.3K]

Answer:

The center is at (-3, -2) and the radius = 1.

Step-by-step explanation:

We can do this by converting the given equation to standard form.

x^2+6x+y^2+4y+12=0

x^2+6x+y^2+4y = -12

Completing the square on the x and y terms:

(x + 3)^2 - 9 + (y + 2)^2 - 4 = -12

(x + 3)^2 + ( y + 2)^2 = -12 + 9 + 4

(x + 3)^2 + ( y + 2)^2 = 1

So the center is (-3, -2) and the radius = 1.

A wooden plank is cut into three pieces. The ratio of the length of the pieces of wood is 6:10:12. If the length of the original
iren2701 [21]

Answer:

290 centimetres

Step-by-step explanation:

The ratio of the length of the pieces of wood is 6 : 10 : 12.

We have to find the total ratio first:

6 + 10 + 12 = 28

The longer piece of wood has ratio 10.

The length of the original wooden plank is 812 centimetres, therefore, the length of the longer piece of wood is:

10/28 * 812 = 290 centimetres
