The equation that describes the which gives the area of the pen, A, as a function of x, the length of fence parallel to the barn is A = 130x - x²
<h3>How to find area of a rectangle?</h3>
The pen is rectangular. Therefore,
area of a rectangle = lw
where
Therefore,
perimeter = 2w + l
perimeter = 2w + x
130 = 2w + x
130 - x = 2w
w = 65 - 1/ 2 x
A = xw
A = x(65 - 1/ 2 x)
A = 65x - 1 / 2 x²
Therefore, the function that represents A, the area of the pen is as follows:
A = 130x - x²

Answer:
30/7
Step-by-step explanation:
xy/7
(-6)(-5)/7
30/7
Step-by-step explanation:
The formulae to find them are:
- arithmetic mean in individual series = sum x/N
- arithmetic mean in discrete data= sum fx/N
- arithmetic mean in continuous data= sum fm/N
and mode= number of greatest frequency.
(note; f is frequency, N is number of data and x is x is the raw data)

Answer:
$461.15
Step-by-step explanation:
Total amount of items:
Add all the prices together
399.99+24.99+5=429.98
Sales tax:
Convert 7.25% to a decimal
7.25/100=0.0725
Multiply the total by the decimal
429.98*0.0725=31.17355
Final cost:
Add the sales tax and total amount
429.98+31.17355=461.15355
Round to the nearest cent/hundreth
$461.15
Hope this helps! :)
