(iv) (6-3(1)/(8))/(5+(3)/(4+(5)/(9)))

Q.the sum of the infinite series 1+(2)/(3)*(1)/(2)+(2)/(3)*(5)/(6)*(1)/(2^(2))+(5)/(3)*(5)/(6)*(8)/(9)*(1)/(2^(3))+... is

[[3,5,-93,5,-9-1,4,-7]]+X=[[6,2,34,8,6]]

The order of the matrices [{:(1,2,3),(4,5,-1):}], [{:(2,4),(9,2),(6,3),(4,1):}] , [{:(4,5,6),(3,2,1),(9,8,7):}] respectively are :

The expression (5(5)/(8))/(6(3)/(7)) of (6(7)/(11))/(9(1)/(8))-:(8)/(9)(2(3)/(11)+(13)/(22)) of (3)/(5) equals (a) 1 (b) (1)/(2)( c) (7)/(9)( d) (5)/(12)

A square is inscribed in the circle x^2+y^2-2x+4y-93=0 with its sides parallel to the coordinate axes. The coordinates of its vertices are (-6,-9),(-6,5),(8,-9),(8,5) (-6,-9),(-6,-5),(8,-9),(8,5) (-6,-9),(-6,5),(8,9),(8,5) (-6,-9),(-6,5),(8,-9),(8,-5)
