Answer:
a^5x^5, 10a^5x^4, 40a^5x^3
Step-by-step explanation:
Use pascal's triangle for the first one
(2+x)^5 * a^5
= x^5a^5 + 5*2^1*x^4*a^5 + 10*2^2*x^3*a^5 ...
= a^5x^5 + 10a^5x^4+ 40a^5x^3 ...
Answer:
$6.34
Step-by-step explanation:

ANSWER
$16,384
EXPLANATION
From the question we have that,
Nadir saves $1 the first day of a month, $2 the second day, $4 the third day, and so on.
This forms a geometric sequence,

The first term of this sequence is

The common ratio is

The general term of a geometric sequence is given by the formula:

To find the 15th term, we plug in a=1, r=2 and n=15.



The amount he will save on the 15th day is $16,384
