Find the general form, Ax2+Ay2+Dx+Ey+F=0, by identifying the coefficients A,D,E,&F center:(0,1); r=1 (x-0)2+(y-1)2=1 x2+y2-2
siniylev [52]

Answer:

The value of A is 1, D is 0, E is -2 and F is 0.

Step-by-step explanation:

The given equation is

Ax^2+Ay^2+Dx+Ey+F=0             ...(1)

The standard form of the circle is

(x-h)^2+(y-k)^2=r^2

Where, (h,k) is the center of the circle and r is the radius.

(x-0)^2+(y-1)^2=1

x^2+y^2-2y+1-1=0

x^2+y^2-2y=0

It can be written as

x^2+y^2+0x-2y+0=0                          ....(2)

On comparing (1) and (2) we get.

A=1

D=0

E=-2

F=0

Therefore the value of A is 1, D is 0, E is -2 and F is 0.

Please HELP!!!!!!! i dont understand this
weqwewe [10]

Answer:

The answer is A, -4.

Step-by-step explanation:

For solving the parenthesis, 2/3 + 2 = 8/3, Since 2 is equivalent to 6/3.

-4 + 8/3 = -4/3. n = 1/3, so the equation would be -4/3 divided by 1/3. that would equal to -4.
