If the number of positive integral solutions of `u+v+w=n` be denoted by `P_(n)` then the absolute value of `|{:(P_(n),P_(n+1),P_(n+2)),(P_(n+1),P_(n+2
Correct Answer - A `(a)` As `u+v+w=n` and `u,v,w ge 1` Now, number of solutions of `u+v+w=nimpliesP_(n)=^(n-1)C_(n-3)` Similarly `P_(n+1)=^(n)C_(n-2)`, `P_(n+2)=^(n+1)C_(n-1)`, `P_(n+3)=^(n+2)C_(n)`, `P_(n+4)=^(n+3)C_(n+1)`. Now `Delta=|{:(.^(n-1)C_(n-3),.^(n)C_(n-2),.^(n+1)C_(n-1)),(.^(n)C_(n-2),.^(n+1)C_(n-1),.^(n+2)C_(n)),(.^(n+1)C_(n-1),.^(n+2)C_(n),.^(n+3)C_(n+1)):}|` `=(1)/(8)|{:(((n-1)!)/((n-3)!),(n!)/((n-2)!),((n+1)!)/((n-1)!)),((n!)/((n-2)!),((n+1)!)/((n-1)!),((n+2)!)/(n!)),(((n+1)!)/((n-1)!),((n+2)!)/(n!),((n+3)!)/((n+1)!)):}|` `=(1)/(8)|{:((n-1)(n-2),n(n-1),n(n+1)),(n(n-1),n(n+1),(n+1)(n+2)),(n(n+1),(n+2)(n+1),(n+3)(n+2)):}|` `Delta=(1)/(2)|{:(1,n(n-1),n),(1,n(n+1),(n+1)),(1,(n+2)(n+1),(n+2)):}|` (On applying (first) `C_(3)...

If the distance of a point from X-axis is 8 units and its distance from Y-axis is 3 units then the point is denoted by
Correct option is (D) (3, 8) The distance of point from Y-axis is x = 3 and the distance of point from X-axis is y = 8. \(\therefore\) Point is (3, 8).
