Show that the points P" "(-2," "3," "5) , Q" "(1," "2," "3) and R (7," "0," "-1) are collinear.

Show that the points (-2,3,5),(1,2,3) and (7,0,-1) are collinear.

Find the matrix A such that : [(1 ,0 ),(0 ,1)]A=[(3 ,3 ,5 ),(1, 0 ,1)] (ii) A[(1, 2, 3 ),(4, 5 ,6)]=[(-7,-8,-9 ),(2, 4 ,6)]

Show that(i) [[5,-1],[ 6 ,7]][[2, 1],[ 3 ,4]]!=[[2, 1],[ 3, 4]][[5,-1],[ 6, 7]] (ii) [[1, 2, 3],[ 0, 1, 0],[ 1, 1, 0]][[-1, 1, 0],[ 0,-1, 1],[ 2, 3, 4]]!=[[-1, 1, 0],[ 0,-1, 1],[ 2, 3, 4]][[1 ,2 ,3],[ 0, 1, 0],[ 1, 1, 0]]

Find the mode of 0, 5 , 2 , 7 , 2 , 1 , 1, 3 , 2 , 4 , 5 , 7 , 5 , 1 and 2 .

Prove that the point A(1,2,3), B(-2,3,5) and C(7,0,-1) are collinear.

In a dice 1, 2, 3 and 4 dots are on the adjacent faces, in a clockwise order, and 5 and 6 dots at the top and bottom. When 1 dot is at the top, then what number of dots will be at the bottom? एक पासे में बिंदु 1, 2, 3 और 4 दक्षिणावर्त क्रम में मौजूद है | 5 और 6 कर्मानुसार ऊपरी और निचली सतह पर मौजूद है | बताएं की 1 के विपरीत कौन सा बिंदु होगा ?

If |{:(- 1, 7 , 0),(2, 1, -3),(3, 4, 1):}| = A, then |{:(13, -11 , 5),(- 7, -1 , 25),(-21 , -3, -15):}| is

If A=[(2 ,3,-5 ),(1, 2,-1)] and B=[(0, 5,1),(-2, 7, 3)] , find A+B and A-B
