6. You have 220 feet of fencing material to enclose a rectangular area for your pet animals. Let x = the length of the rectangular enclosure. (a) [7 points] Set up the function A(x) that represent the enclosed area. (b) [7 points] What should be the dimensions of the enclosed area? (c) [2 points] What is the maximum area of the enclosed area?
Answer:
I will start with (c)
(c) What is the maximum area of the enclosed area?
the maximum area of a rectangle is always given by a square figure
since the square has 4 equal sides, each side will be 220 / 4 = 55 ft long
maximum area = 55 x 55 = 3,025 ft²
(b) What should be the dimensions of the enclosed area?
the dimensions would be 55 ft in length by 55 ft in width
(a) Set up the function A(x) that represent the enclosed area.
perimeter of the rectangle = 220
we have 4 equal sides, so
A(x) = x²

Answer:
[tex]A\approx1608.7\text{ yards}^2[/tex]
Step-by-step explanation:
We can use the alternate formula for the area of a triangle:
[tex]A=\frac{1}{2}ab\sin(C)[/tex]
Where a and b are the side lengths, and C is the angle between the side lengths.
We know that one side length is 60 and the other is 70.
The angle between them is 50°.
So, substitute 60 for a, 70 for b, and 50° for C. This yields:
[tex]A=\frac{1}{2}(60)(70)\sin(50)[/tex]
Evaluate using a calculator. Make sure you’re in Degrees Mode.
Therefore, the approximate area is:
[tex]A\approx1608.7\text{ yards}^2[/tex]

Start with the top figure. Which transformation was used to create the pattern?
The transformation that was used to create the pattern is rotation. The correct option is A, rotation.
What is the transformation in logic?If two formulae are logically identical, either one may replace the other in any well-formed context without changing anything's truth value or inferential qualities. This is a fundamental property of logic.
The given figure in the top is needed to be transformed such that the pattern given below is produced. Therefore, if we observe the figure at the top and the pattern, then it can be seen that the given figure is rotated by 90° to create the given pattern. The pattern will be formed.
Hence, the transformation that was used to create the pattern is rotation.

What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
The sum of the lengths of any two sides of a triangle is greater than the length of the third side (Triangle Inequality Theorem)
So AC+BC>AB
27+54>AB
81>AB
AB<81
27+AB>54
AB>54-27
AB>27

AB>-27
Hence, 27 < AB < 81 expresses all possible lengths of segment AB

What is 50 percent of 62?
0.31
3.1
31
310
Answer:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 62 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 62 is 100%, so we can write it down as 62=100%.
4. We know, that x is 50% of the output value, so we can write it down as x=50%.
5. Now we have two simple equations:
1) 62=100%
2) x=50%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
62/x=100%/50%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 50% of 62
62/x=100/50
(62/x)*x=(100/50)*x - we multiply both sides of the equation by x
62=2*x - we divide both sides of the equation by (2) to get x
62/2=x
31=x
x=31
now we have:
50% of 62=31
50 percent of 62 is equal to 31. the correct answer is option C) 31.
To convert a number to a percentage, you typically multiply the number by 100 and add the percentage symbol (%).
To find 50 percent of 62, we can calculate it by multiplying 62 by 0.50 (which is equivalent to 50 divided by 100).
62 * 0.50 = 31
Therefore, 50 percent of 62 is equal to 31.
So, the correct answer is option C) 31.
Options A) 0.31, B) 3.1, and D) 310 are not correct as they either incorrectly place the decimal point or exaggerate the value by orders of magnitude. The accurate value is 31.
