Q1a.                                                                    SOLUTION from the format of the matrix we can get our 7×7 adjacency matrix using this format:  │ a11 a12 a13 a14 a15 a16 a17│ │ a21 a22 a23 a24 a25 a26 a27│ │ a31 a32 a33 a34 a35 a36 a37│ │ a41 a42 a43 a44 a45 a46 a47│ │ a51 a52 a53 a54 a55 a56 a57│ │ a61 a62 a63 a64 a65 a66 a67│ │ a71 a72 a73 a74 a75 a76 a77│ Therefore:             │ 2  0  1  0  1  0  1│             │ 0  2  0  0  1  0  0│             │ 1  0  2  0  1  0  1│ A(G)= │ 0  0  0  2  0  0  0│             │ 1  1  1  0  2  0  1│             │ 0  0  0  0  0  2  0│             │ 1  0  1  0   1 0  2│ Q1b. Then C(v) is nothing but component of the graph. Then: C(v) = 3 then as you can see that we have two isolated vertices from our graph form by the above adjacency matrix which are V6 and V4 therefore V6 is a cut-vertex and V4 is also a cut-vertex while V1,V2,V3,V5 and V7 are vertex-cut.   Q2,Q3 and Q4 very soon by God will

Q1. List all possible topologies on the set. X = {a,b,c}                                                                      SOLUTION . There are 29 distinct topologies on X these are: 1.{X,∅} 2.{X,∅,{a}} 3.{X,∅,{b}} 4.{X,∅,{c}} 5.{X,∅,{a,b}} 6.{X,∅,{a,c}}  7.{X,∅,{b,c}}  8.{X,∅,{a},{b,c}}  9.{X,∅,{a},{a,b}}  10.{X,∅,{a},{a,c}}  11.{X,∅,{b},{a,b}} 12.{X,∅,{b},{b,c}} 13.{X,∅,{b},{a,c}} 14.{X,∅,{c},{a,c}} 15.{X,∅,{c},{b,c}} 16.{X,∅,{c},{a,b}} 17.{X,∅,{a},{b},{a,b}} 18.{X,∅,{a},{c},{a,c}} 19.{X,∅,{b},{c},{b,c}}  20.{X,∅,{a},{a,b},{a,c}} 21.{X,∅,{b},{a,b},{b,c}} 22.{X,∅,{c},{a,c},{b,c}} 23.{X,∅,{a},{b},{b,c},{a,b} 24.{X,∅,{a},{c},{a,b},{a,c} 25.{X,∅,{a},{b},{a,b},{a,c}}  26.{X,∅,{a},{c},{a,c},{b,c}} 27.{X,∅,{b},{c},{a,c},{b,c}} 28.{X,∅,{b},{c},{a,b},{b,c}} 29.{X,∅,{a},{b},{c},{a,b}{a,c},{b,c}} Q1b. ConsiderS = {{a,b},{a,c}},whereX = {a,b,c} 1 obtain the topology generated by S(i.eτ(S)). Is S a basis?. SOLUTION HINT!!. To generate topology from S

If ×=4 and y= 6 find y when ×=4 Solution Y=6 Proof: Becouse the value of X is still the same Hence the prove
