X2+5x+y2-y=-2
X2+2*5x2+(5/2)^2-(5/2)^2+y2-2*y/2+(1/2)^2-(1/2)^2=-2
(x+5/2)^2+(y-1/2)^2-13/2=-2
(x+5/2)^2+(y-1/2)^2=9/2
So centre =(-5/2,1/2)
Radius=(9/2)^(1/2)

Step-by-step explanation:
First question answer is 390.66 m
1 mile_1609.34 m
1000m=1km
2km=2x1000=2000m
2000km - 1609.34m=390.66m
Se ond question 6x10000=60000cm2
Answer:
B
Step-by-step explanation:
Given that r is inversely proportional to s then the equation relating them is
r = 
← k is the constant of proportion
To find k use the condition r = 16 when s = 3
k = rs = 16 × 3 = 48
r = 
← equation of variation → B
