Answer:
1.
centre(h,k)=(-13,9)
radius (r)=6
we have
equation of the circle is
(x-h)²+(y-k)²=r²
(x+13)²+(y-9)²=6²
x²+26x+169+y²-18y+81=36
x²+y²+26x-18y+169+81-36=0
x²+y²+26x-18y +214=0
is a required equation of the circle.
2.
centre(h,k)=(1,-1)
radius (r)=11
we have
equation of the circle is
(x-h)²+(y-k)²=r²
(x-1)²+(y+1)²=11²
x²-2x+1+y²+2y+1=121
x²+y²-2x+2y=121-2
x²+y²-2x+2y=119
is a required equation of the circle.
Answer: 2

11, because 11 times 1 is 11 and 11 times 4 is 44.
Step-by-step explanation:
1/4
90%
1.5
0.005
6/10
25%
2/10
49.5
3/4
0.4
The absolute value is always positive, so the numbers would be 4 and 4.
Those are two equal numbers so it is: equal to
