20% of 106
= 0.20 * 106
= 21.2
21.2 = 10.6% of 21.2 / 0.106
= 200 answer
2. 56 * 0.055 / 0.35
= 8.8
3. 6.4 / 0.8 = 8
hello :<span>
<span>an equation of the circle Center at the
A(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : a = -2 and b = 1 (Center at the A(-2,1))
r = AP......P( -4 , 1)
r² = (AP)²
r² = (4+2)² +(1-1)² = 36
an equation of the circle that satisfies the stated conditions.
Center at </span></span> A(-2,1), passing through P(-4, 1) is : (x+2)² +(y-1)² = 36
