Answer: G would be at (1,0)
F (-1,3)
Y (-1,0)
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)
200+ 10 + 6= 216

Answer:
The total cost of the petrol is 2.075 cents.
Step-by-step explanation:
The cost of per gallon petrol = 0.83
Drive per gallon = 8 miles
Here, total distance traveled = 20 miles.
So, the total petrol used for 20 miles = (20 / 8) gallons
= 2.5 gallons
Now, cost of petrol per gallon = 0.83 cents
So, total cost of petrol = 0.83 x 2.5 = 2.075 cents
Hence, the total cost of the petrol is 2.075 cents.
