Answer:
n=10
a10= - 3 (2)^(10-1)= -3(2)^9
= -1536
For this case we have that by definition, a monomial is an algebraic expression that consists of a single term or in which the terms that form it are related by the product operation.
<em>Example:</em>

Thus, the correct option is option A.

Answer:
Option A
Partition the set A into 4 subsets:
{1, 8}, {2, 7}, {3, 6}, and {4, 5},
each consisting of two integers whose sum is 9. If 5 integers are selected from A,
then by the Pigeonhole Principle at least two must be from the same subset. But
then the sum of these two integers is 9.
58.50 - 45 = 13.50
13.50 / 45 x 100 = 30%
answer: mark up 30%
