You're on the right track. If they generated 380 less than 2012, then in 2013 they generated 9782-380 = 9402.
They used 10472 in 2012, so 10472+390 = 10862 used in 2013. now subtract used from produced to see how much they had to buy...
10862-10472 = 390
They had to buy 390khW from the power company.
Answer:
(x-2)2+(y-5)2=92
or
(x-2)2+(y-5)2=81
Step-by-step explanation: Center:(2,5)
The center of a circle is a point from which all points on a circle are the same distance.
Radius:9
The radius of a circle is the length of a line segment from its center to its perimeter.
The radius is typically denoted as "r" or "R".
Diameter:18
The diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle.
Circumference or (or Permieter) = 2*π*R = 2*3.14*9 = 56.5486677646163
The circumference of a circle is the distance around it.
Area:254.469004940773
Area of a Circle is the amount of space occupied by the circle.The area of a circle is p times the radius squared, which is written: A = π*R2.
The standard form for the equation oif a circle is
(x-a)2+(y-b)2=r2
And in our particular case:
(x-2)2+(y-5)2=92
(x-2)2+(y-5)2=81
The general form for the equation of a circle is
x2 + y2 + Ax + By + c = 0
We can get the general form by expanding the equation of the standard form
(x-a)2+(y-b)2=r2
(x-2)2+(y-5)2=92
(x-2)2+(y-5)2=81
x2-4x+4+y2-10y+25=81
x2+y2-4x-10y-52=0

Answer:
Area of parallelogram is equal to 
Step-by-step explanation:
It is given length pf parallelogram which is equal to base of parallelogram is b=15 cm
Height of parallelogram h = 7.5 cm
We have to find the area of the parallelogram.
Area of parallelogram is equal to multiplication of base and height.
Therefore area of parallelogram is,
, here b is base and h is height.
So 
Therefore area of parallelogram is equal to
