Standard form of a circle" (x-h)²+(y-k)²=r², (h,k) being the center, r being the radius.
in this case, h=-2, k=6, (x+2)²+(y-6)²=r²
use the point (-2,10) to find r: (-2+2)²+(10-6)²=r², r=4
so the equation of the circle is: (x+2)²+(y-6)²=4²
Answer:
The gradient is 3/7 make y the subject. Then put the coordinates in the equation.
Step-by-step explanation:
Answer:5625 yards
Step-by-step explanation:
2/5=6/15
1/3=5/15
6/15+5/15=11/15
(15/15)-(11/15)=4/15
1500/4=375
375×15=5625
In (A), we have 9 : 2.
Multiply by 2, we get 18 : 4
In (B), we have 36 : 8.
Divide by 2, we get, 18 : 4.
In (D), we have 54 : 12.
Divide by 3, we get, 18 : 4.
Hence, (C) is not equivalent to the given statement.
