Answer:

Step-by-step explanation:
The given sequence is
64, 16, 4, 1



It is a geometric series because it has a common ratio
.
First term is 64.
The explicit formula of a geometric series is

where, a is first term and r is common ratio.
Substitute a=64 and r=1/4 in the above function.

Therefore, the required explicit formula is
.
Answer:

Step-by-step explanation:
The given expression is
.
The technique that can be used to factor this polynomial is the difference of two squares.
We rewrite the two expressions as;

Recall that;

Answer:
$45.45
Step-by-step explanation:
Please find attached an image of the shoe that was used in answering this question
From the image, the price of the shoe is $59.95
Let x be the amount you had with you
The equation that would be used to solve this question is :
(x + 20) - $59.5 = $5.50
Solve for x
x = $45.45
