Considering her change, it is found that she will donate $0.28 to the animal shelter.
<h3>How to find the amount of change in a purchase?</h3>

In this problem, the price of the products bought is given by:
$15.74 + $3.98 = $19.72
She paid $20, hence the change is given by:
$20 - $19.72 = $0.28.

Taylor series is 
To find the Taylor series for f(x) = ln(x) centering at 9, we need to observe the pattern for the first four derivatives of f(x). From there, we can create a general equation for f(n). Starting with f(x), we have
f(x) = ln(x)

.
.
.
Since we need to have it centered at 9, we must take the value of f(9), and so on.
f(9) = ln(9)

.
.
.
Following the pattern, we can see that for
,
This applies for n ≥ 1, Expressing f(x) in summation, we have

Combining ln2 with the rest of series, we have

Answer:
length 60 feet
length 2=60 feet
width 1=30feet
width 2=30feet
those is because there is 4 sides to a rectangle
Step-by-step explanation:
because the length is twice the width, 2x 30=length
