4.	Simplify 45 multiply 2 1/3
Answer» So, At first = 45 x 2 integer 1/3 = 45 x 7/3 = 45x7 and 1x3 = 45x7 = 315 = 1x3 = 3 = 315 3 Reduce = 315 DIVIDED by 3 = 3 x 105 = 315 = 105 is the ANSWER

4.

Simplify 45 multiply 2 1/3

Answer»

So, At first = 45 x 2 integer 1/3

= 45 x 7/3

= 45x7 and 1x3

= 45x7 = 315

= 1x3 = 3

= 315

3

Reduce = 315 DIVIDED by 3

= 3 x 105 = 315

= 105 is the ANSWER

31.

For any matrix A and B other than identity matrix if AB=B and BA=A and (A+B)^3 = K (A+B), Find K ?

Answer»

Step-by-step explanation:

=>Here,

AB=B & BA=A

(AB).A=B.A & (BA).B=A.B

A.(BA)=B.A & B.(AB)=A.B

A.A=A & B.B=B

A²=A & B²=B

=>Now,

(A+B)³ = K(A+B)

(A+B)³-K(A+B) =0

(A+B)²-KI =0

(A²+2AB+B²)-KI =0

(A+2A+B) -KI =0

(3A+B)-KI=0

DIAG[3, 3, 3] + Diag[1, 1, 1] = Diag[K, K, K]

Diag[4, 4, 4] = Diag[K, K, K]

(4)Diag[1, 1, 1] = (K)Diag[1, 1, 1]

=> K=4

Answer» Answer: The given points are A(1,5), B(2,3) and C(−2,−11). Let us calculate the distance : AB, BC and CA by using distance formula. AB= (2−1) 2 +(3−5) 2 = (1) 2 +(−2) 2 = 1+4 = 5 units BC= (−2−2) 2 +(−11−3) 2 = (−4) 2 +(−14) 2 = 16+196 = 212 =2 53 units CA= (−2−1) 2 +(−11−5) 2 = (−3) 2 +(−16) 2 = 9+256 = 265 = 5 × 53 units From the above we see that : AB+BC  =CA Hence, the above stated points A(1,5), B(2,3) and C(−2,−11) are not COLLINEAR.
