a symmetric group S5 acts on the set X5 = {(i, j) : i, j ∈ {1, 2, 3, 4, 5}}.
S5 will also act on this set. Consider the subgroup H = <(1, 2)(3, 4), (1, 3)(2, 4)>≤ S5. (a) Find the orbits of H in this action. Justify your answers. (b)
For each orbit find the stabiliser one of its members. Justify your answers.

Speaker A: Americans were opposed to British restrictions on their colonial governments, and this was a major factor in bringing on the Revolution.
Speaker B: The basic cause was Great Britain’s imposition of taxes on the colonists. Colonists fought in order to avoid taxation.
Speaker C: Britain’s economic policies, designed to benefit British merchants, were very harmful to colonial merchants.
Speaker D: Colonial reaction to the Boston Massacre and the Battle of Bunker Hill eliminated all possibility for peaceful settlement.

Let {an} be a sequence defined recursively by a1 = 1 and an+1 = 2√ 1 + an where n ∈ N
(b) Does {an} converge or diverge? Justify your answer, making sure to cite appropriate hypotheses/theorem(s) used. Hint : Try BMCT [WHY?].
(c) (Challenge) If {an} converges then find its limit. Make sure to fully justify your answer.

Consider the linear program:
??? 1? + 2? ?. ?.
1? ≤ 5
1? ≤ 5
2? + 2? = 12 ?, ? ≥ 0
a) Show the feasible region.
b) What are the extreme points of the feasible region?
c) Find the optimal solution using the graphical procedure.
d) Graph it on excel
Can you thoroughly explain the steps why and how you got the answers and how to get the point to plot the graph. I have the final answers but I'm unsure how about the steps. I need more help explaining the steps, the final answers aren't important to me.
