Two schools P and Q want to award their selsected students on the values of Discipline, Politeness and Punctuality. The school P wants to award Rs. x each, Rs.y each and Rs.z each for the three respective values to its 3,2 and 1 students with a total amount money of Rs.1000/- School Q wants to spent Rs.1500/- to award its 4, 1 and 3 students on the respective values. If the total amount of awards for one prize on each value is Rs.600/-, using matrices, find the award money for each value.
a line can be drawn which divides the following figure into two separate pare. These two parts is could then fit together to make a square, which two numbers would you connect to make this line
If li,mi,ni where i=1,m=2,n=3 denote the direction cosines of 3 mutually perpendicular vectors in space ,prove that AA^T=I wher A is a matrix and A^T is its transpose and I is a indentity matrix
if A is a square matrix such that, A2=A, then write the value of (1+A)2-3A.
if B, C ARE n ROWED SQUARE MATRICES AND IF A=B+C , BC=CB ,C2=0 ,THEN SHOW THAT FOR EVERY n is the element ofN, An+1 =Bn(B+(n+1)C).
if matrix cos2pi/7 -sin2pi/7
