Answer:
Step-by-step explanation:
1) b) 284 /4 =280/4 = 70 { 4 * 7 =28 }
2)a) 5747/8 = 5600/8 = 70 { 7 * 8 =56}
2) b) 2312/7 = 2100/7 = 30
The equation of a circle that has a center at (h,k) and radius of r is
(x-h)²+(y-k)²=r²
so given center (-5,-7)
(x-(-5))²+(y-(-7))²=r²
(x+5)²+(y+7)²=r²
passes through (0,0)
sub the point to find r
(0+5)²+(0+7)²=r²
25+49=r²
74=r²
the equation is
(x+5)²+(y+7)²=74 or equivilently
(x+5)²+(y+7)²=(√74)²
