Answer:
a) A n (B' n C') = {3, 9}.
b) (AUB) n (BUC) = {2,4,5,6,7,8}
Step-by-step explanation:
a) Rewriting C ; C = {4,5,6,7,8}
B' = {3,5,7,9} and C' = {2, 3, 9}
so (B' n C') = {3, 9}
and A n (B' n C') = {3, 9}.
b) {A U B} = { 2,3,4,5,6,7,8,9} and {B U C} = {2,4,5,6,7,8}
so (AUB) n (BUC) = {2,4,5,6,7,8}
7√6 - 5√7
5√7 + 12√6 - 10√7 - 5√6 (rearranging)
= (5√7 - 10√7) + (12√6 - 5√6) (factor out √6 and √7 respectively)
= (5 - 10) √7 + (12 - 5)√6
= -5√7 + 7√6 (rearrange)
= 7√6 - 5√7

Compounded Calculation Interest Rate For One Period
Semiannually, every 6 months, every half of a year (.06)/2 0.03
Annually, every year .06 .06
6% means 6 percent (from Medieval Latin for per centum, meaning "among 100"). 6% means 6 among 100, thus 6/100 as a fraction and .06 as a decimal
