If the farmer has 648 feet of fencing, what are the dimensions of the region which enclose the maximal area?
Answer:
Length = 162 feet and Width = 108 feet.
Step-by-step explanation:
The area of a 2D form is the amount of space within its perimeter. The area of this region will cover is 26,244 feet².
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
A four-sided figure covers the maximum area when the length of its four sides is equal. Therefore, the length and the width of the region will be equal. Thus, we can write the length of the fence as,
4x = 648 feet
x = 648/4 feet
x = 162 feet
Now, the area this region will cover is,
Area = 162 feet x 162 feet
= 26,244 feet²
Hence, the area of this region will cover is 26,244 feet².

Answer: B. It is a perfect square
Step-by-step explanation:
Radical Expressions
Melissa multiplied [tex]\sqrt{a}[/tex] and [tex]\sqrt{b}[/tex] and got a rational number.
We are also given that a and b are both natural numbers. It means their product must be not only rational but also a natural number.
We can write that product like:
[tex]\sqrt{a} \cdot \sqrt{b}=\sqrt{a\cdot b}[/tex]
If the result is a natural number, then the product of a and b must be a perfect square. so the radical disappears.
Answer: B. It is a perfect square

Evaluate the double integral. 2y2 dA, D is the triangular region with vertices (0, 1), (1, 2), (4, 1) D
Answer:
[tex]\mathbf{\iint _D y^2 dA= \dfrac{22}{3}}[/tex]
Step-by-step explanation:
From the image attached below;
We need to calculate the limits of x and y to find the double integral
We will notice that y varies from 1 to 2
The line equation for (0,1),(1,2) is:
[tex]y-1 = \dfrac{2-1}{1-0}(x-0)[/tex]
y - 1 = x
The line equtaion for (1,2),(4,1) is:
[tex]y-2 = \dfrac{1-2}{4-1}(x-1) \\ \\ y-2 = -\dfrac{1}{3}(x-1)[/tex]
-3(y-2) = (x -1)
-3y + 6 = x - 1
-x = 3y - 6 - 1
-x = 3y - 7
x = -3y + 7
This implies that x varies from y - 1 to -3y + 7
Now, the region D = {(x,y) | 1 ≤ y ≤ 2, y - 1 ≤ x ≤ -3y + 7}
The double integral can now be calculated as:
[tex]\iint _D y^2 dA= \int ^2_1 \int ^{-3y +7}_{y-1} \ 2y ^2 \ dx \ dy[/tex]
[tex]\iint _D y^2 dA= \int ^2_1 \bigg[ 2xy ^2 \bigg]^{-3y+7}_{y-1} \ dy[/tex]
[tex]\iint _D y^2 dA= \int ^2_1 \bigg[2(-3y+7)y^2-2(y-1)y^2 \bigg ] \ dy[/tex]
[tex]\iint _D y^2 dA= \int ^2_1 \bigg[-6y^3 +14y^2 -2y^3 +2y^2 \bigg ] \ dy[/tex]
[tex]\iint _D y^2 dA= \int ^2_1 \bigg[-8y^3 +16y^2 \bigg ] \ dy[/tex]
[tex]\iint _D y^2 dA= \bigg[-8(\dfrac{y^4}{4}) +16(\dfrac{y^3}{3})\bigg ] ^2_1[/tex]
[tex]\iint _D y^2 dA= \bigg[-8(\dfrac{16}{4}-\dfrac{1}{4}) +16(\dfrac{8}{3}-\dfrac{1}{3})\bigg ][/tex]
[tex]\iint _D y^2 dA= \bigg[-8(\dfrac{15}{4}) +16(\dfrac{7}{3})\bigg ][/tex]
[tex]\iint _D y^2 dA= -30 + \dfrac{112}{3}[/tex]
[tex]\iint _D y^2 dA= \dfrac{-90+112}{3}[/tex]
[tex]\mathbf{\iint _D y^2 dA= \dfrac{22}{3}}[/tex]
To answer this question, we need, first get the equations for the lines that enclosed the surface, and integrate according to the limits these equations give.
The solution is:
A = 22/3 square units
Let´s call points:
P ( 0 , 1 ) Q ( 1 , 2 ) and R ( 4 , 1 )
The equation for the line between P and R is:
y = 1
The equation for the line between P and Q is:
Slope-intercept equation is y = m×x + b
The slope m₁ = ( 2 - 1 ) / ( 1 - 0 ) m₁ = 1
and the line passes over the point x = 0 y = 1 ; then
1 = 0 +b b = 1
y = x + 1 ⇒ x = y - 1
The equation for the line between Q and R is:
m₂ = ( 1 - 2 ) / ( 4 - 1) m₂ = - 1/3
y = ( -1/3)× x + b
when x = 1 y = 2
2 = ( - 1/3)×(1) + b
2 + 1/3 = b
b = 7/3
y = - (x/3) + 7/3 ⇒ x = 7 - 3×y
The double integral becomes:
A = 2×∫∫ y² dx dy ⇒ A = 2 ×∫₁² y²dy ∫dx | (y - 1 ) y ( 7 - 3y)
A = 2 ×∫₁² y²dy × x | ( y - 1 ) y ( 7 - 3y)
A = 2 ×∫₁² y²dy × [ 7 - 3×y - ( y - 1 )]
A = 2 ×∫₁² y²dy × (8 - 4×y ) ⇒ A = 2 ×∫₁² (8×y² - 4×y³ ) dy
A = 2 × [ (8/3)×y³ - y⁴ | ₁²
A = 2 × [ 64/3 - 16 - (8/3) + 1 ]
A = 2 × ( 56/3 - 15 )
A = 2 × ( 56 - 45 /3)
A = 2 × 11/3
A = 22/3 square units

Lauren bought a jacket that was on sale. She paid
40% of the original price of $75. How much did
Lauren pay for the jacket? Solve this problem any
way you choose.
Lauren paid $30 for the jacket on sale.
What is Percentage?Percentage of any number is calculated by dividing the number with the whole and then multiplying the result with 100.
Similarly the opposite steps can be used to find the original number out of the percentage.
So percentage is the ratio or number which can be expressed as a fraction of 100 or in simple terms, percentage is the part per 100.
The symbol we use to denote percentage is %.
Lauren bought a jacket that was on sale.
Original price of the jacket = $75
Amount Lauren paid is the 40% of the original price $75.
Actual price paid = 40% × 75
= (40/100) × 75
= 0.4 × 75
= 30
That is the actual price is $30.
Hence, if Lauren paid 40% of the original price $75, then the amount Lauren paid for the jacket is $30.

The Valley High School student council is planning a dance. The
school has 480 students. The lowest possible ticket price is $3.00,
and they estimate that for every $0.20 increase in ticket price, 20 fewer
students will attend. What ticket price will maximize
the student council's profit?
SELECT ONE OPTION BELOW:
$4.20
$3.90
$3.50
$4.00
Answer:
$3.90
Step-by-step explanation:
its B
The price of the ticket at which the student councils will maximize the profit is $3.90.
Option B is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of students = 480
Lowest ticket price = $3
Ticket price = $4.20
This means,
4.20 - 3 = 1.20
There is an increase of $1.20 which is 0.20 x 6 = $1.20.
The number of students who attended when the ticket price is $4.20.
= 480 - (6 x 20)
= 480 - 120
= 360
Profit:
= 360 x 4.20
= $1512
Ticket price = $3.90
This means,
3.90 - 3 = 0.90
There is an increase of $0.90 which is 0.20 x 4.5 = $0.90.
The number of students who attended when the ticket price is $3.90.
= 480 - (4.5 x 20)
= 480 - 90
= 390
Profit:
= 390 x 3.90
= $1521
Now,
Ticket price = $3.50
This means,
3.50 - 3 = 0.50
There is an increase of $0.50 which is 0.20 x 2.5 = $0.50.
The number of students who attended when the ticket price is $3.50.
= 480 - (2.5 x 20)
= 480 - 50
= 430
Profit:
= 430 x 3.50
= $1505
Now,
Ticket price = $4.00
This means,
4 - 3 = 1
There is an increase of $1 which is 0.20 x 5 = $1.
The number of students who attended when the ticket price is $4.20.
= 480 - (5 x 20)
= 480 - 100
= 380
Profit:
= 380 x 4.20
= $1520
We see that,
The profit is highest when the ticket price is $3.90.
Thus,
$4 ticket price will maximize the student council's profit.
