If X=8.00+-0.04 cm and Y=4.00+-0.04 cm, then (X)/(Y) should be expressed as (1) 2.00+-0.01 (2) 2.00+-0.02 (3) 2.00+-0.03 (4) 2.00+-0.04

Consider the point A (0,0), B(4,2) and C (8,0) Find the mid-point of AB.

Given the matrix A=[(x,3,2),(1,y,4),(2,2z)]. If xyz=60 and 8x+4y+3z=20, then A(adjA) is equal to (a) [(6,4,0,0),(0,6,4,0),(0,0,6,4)] (b) [(8,8,0,0),(0,8,8,0),(0,0,8,8)] (c) [(6,8,0,0),(0,6,8,0),(0,0,6,8)] (d) [(3,4,0,0),(0,3,4,0),(0,0,3,4)]

The orthocentre of the Delta^( l e) formed by (0,0), (8,0),(4,6) is

If A=[[a,0,00,a,00,0,a]], then |A||AdjA| is equal
