Show that: (a) n∪i=1 Ai is closed if all Ai the are;

b) ∩i∈∧ Ai

is closed if all the Ai are;

c) ∞∩i=1 ki

is not empty if the Ki are non empty closed intervals in R and

Ki ⊇ Ki+1 for all i ≥ 1. (Ai ⊆ Rm for all i).

because they could drop even lower..

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6

well the answer to that is xoxoxo
