Answer:
3, -9, 27,-81,243,-729,2187,-6561,19683,-59049,177147,-531441
the sum is −398,580
Step-by-step explanation:
-0.45 = 9/20
2.77= 2 7/9
5.55 = 5 5/9
The answer is II and III, which is the last choice from above. This is because the symbol "less than (or equal to)" indicated a conjunction, which means we have to take into account that the absolute value can be less than or equal to 15, and greater than or equal to -15. This solution set falls in between the two values, hence, the conjunction.
