grains on the third square,
A chessboard has 64 squares. George places 1 grain of rice on the first square, 2 grains on the second square
8 grains on the fourth square, and so on, until he has placed grains of rice on 10 squares.
Once George has put rice on the 10th square, he has placed a total of
grains of rice on the chess board.

what's that

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
