Given the sets A=[a,b], B=[a,b,c], C=[b,c,d] Prove that if A is a subset of B and B is a subset of C then A is a subset of C

Let A=[a,b,c,d,e,f,g] state whether or not the following family of sets Bi={a,b,e,g},. B2={c},. B3=(d,f} is a partition of A.

consider the relation R=[(1,2),(2,5),(3.10),(4,17),(5,26)]. find the i)range ii)domain iii)inverse

(1)Given the sets A={a,b}, B={a,b,c}, C= {b,c,d}. which of these sets are: (i) Equal (ii) Comparable (iii) Subset (2) Prove that if A is a subset of B and B is a subset of C then A is a subset of C

let U=[a,b,c....z],.A=[a,c,e,f,z,y],.. B=[e,x,y,z],.C=[j,k,l,e,f,y] find (i)(AUC)' (ii) AU(B-A)

A beam of light wavelenght 560 to availing in air is incident on a surface of a transparent material. The incident beam makes an angle of 65degree with the normal and the refracted beam makes an angle of 45degree with the normal. calculate the refractive...

when an object is placed 10cm away from a lens; it is found that the formed is 6cm behind the object on the same side of the lens. Determine the focal lenght of the lens. solution 1/v + 1/u = 1/f u=10cm, v=6cm, f=? 6+10/60 = 1/f 70/60 = 1/f by cross multi...

An astronomical telescope consists an objective of focal lenght 100cm and an eyepiece of focal lenght 8cm. calculate the angular magnification of the telescope and also determine the distance between the two lenses.

In a Newton's rings experiment, the radius of ring of the lens is 10.0m and its diameter is 5.0cm. Determine how many of that rings are produced

a diverging mirror of 52.0 focal lenght produces a virtual image of 26.0cm from the mirror. how far from the mirror should the object be placed? solution f=-52.0cm, v=-26.0cm 1/u + 1/v = 1/f rearranging the terms 1/u = 1/f - 1/v substituting the values of...
