Answer:
see below
Step-by-step explanation:
The smallest size has area b^2
A = s^2
A= b^2 = 24^2 =576 m^2
The middle size has area a^2
1024 = a^2
Take the square root of each side
sqrt(1024) =sqrt(a^2)
32 = a
The side length is 32 m
To find the side length of the largest pasture use the pythagorean theorem
a^2 + b^2 = c^2
32^2 + 24^2= c^2
1024+576 = c^2
1600 = c^2
Taking the square root of each side
sqrt(1600) = sqrt(c^2)
40 = c
The side length is 40 m
The area is 1600 m^2
It is fair since the areas are the same.1600 m^2 = 1600 m^2

As seen in the diagram below, Valeria is building a walkway with a width of � x feet to go around a swimming pool that measures 9 feet by 8 feet. If the total area of the pool and the walkway will be 210 square feet, how wide should the walkway be?
The total area of the pool and the walkway will be 210 square feet, the walkway should be 1.8 feet wide.
Describe Area?In mathematics, area is a measure of the size or extent of a two-dimensional shape or surface. It is typically measured in square units, such as square meters, square feet, or square inches. The area of a shape is calculated by multiplying its length by its width or by using a formula specific to that shape.
The concept of area is fundamental to many areas of mathematics, science, and engineering. It is used to calculate the size of land and buildings in real estate, the amount of material needed for construction, the amount of paint needed to cover a surface, and many other practical applications. In addition, the study of area is important in geometry, calculus, and other areas of mathematics.
Let's start by finding the area of the pool, which is 9 feet by 8 feet:
Area of pool = 9 feet * 8 feet = 72 square feet
Next, we need to add the width of the walkway to each dimension of the pool to find the dimensions of the entire area:
Width of area = 9 feet + 2(width of walkway)
Length of area = 8 feet + 2(width of walkway)
The total area of the pool and walkway is given as 210 square feet, so we can set up the equation:
Area of pool + Area of walkway = 210 square feet
Substituting the formulas for the area of the pool and area of the walkway, we get:
72 + (9 + 2x)(8 + 2x) = 210
Expanding the right side and simplifying, we get:
4x² + 34x - 33 = 0
We can solve for x using the quadratic formula:
x = (-34 ± √(34² - 44(-33))) / (2*4)
x = (-34 ± √(1660)) / 8
x = (-34 ± 40.74) / 8
x = 1.8 or x = -5.075
Since the width of the walkway cannot be negative, the width of the walkway should be 1.8 feet.

Given: (x is number of items) Demand function: d(2) 862.4 – 0.6x2 Supply function: s(x) = 0.5x2 Find the equilibrium quantity: Find the producers surplus at the equilibrium quantity
The producer surplus at the equilibrium quantity is 5488/3 or approximately 1829.33.
The equilibrium quantity is found by setting the demand equal to the supply:
862.4 - 0.6x² = 0.5x²
Simplifying and solving for x, we get:
1.1x² = 862.4
x² = 784
x = 28
So the equilibrium quantity is 28.
The producer surplus at the equilibrium quantity, we first need to find the equilibrium price.
The demand or supply function to do this and since the supply function is simpler, we'll use that:
s(28) = 0.5(28)²
= 196
So the equilibrium price is 196.
The producer surplus at the equilibrium quantity is the area above the supply curve and below the equilibrium price, up to the quantity of 28. The supply curve is a quadratic function can find this area using integration:
∫[0,28] (196 - 0.5x²) dx
= [196x - (0.5/3)x³] from 0 to 28
= (5488/3)
= 1829.33.

Write 18/(sqrt(2)) - 12/(sqrt(32)) in the form (a * sqrt(2))/b where a and b are integers.
The final expression of the algebraic expression is; (30√2)/2
How to solve algebra expressions?The algebraic expression is expressed as;
(18/√2) - 12/√32
Now, we know that √32 can be expressed as;
√(16 * 2) = √16 * √2

Compared to the parent function, how does the value of a affect the graph of y = a|x|?
If a > 1, the graph of y = a|x| will be vertically stretched (or "taller") or if 0 < a < 1, the graph of y = a|x| will be vertically compressed (or "shorter") or If a is negative, the graph of y = a|x| will be a reflection of the graph of y = |x| than the graph of y = |x| than the graph of y = |x|,
What is graph?A graph is a visual representation of a set of objects, called vertices or nodes, that are connected by lines or edges. It is used to study relationships and patterns between these objects.
According to the given information :
The graph of the function y = |x| is a V-shaped graph that passes through the origin, with the arms of the V opening upward and downward at a slope of 1. When we introduce a coefficient 'a' to the function, the graph of y = a|x| is stretched or compressed vertically.
Specifically, if a > 1, the graph of y = a|x| will be vertically stretched (or "taller") than the graph of y = |x|, and the arms of the V will be steeper. On the other hand, if 0 < a < 1, the graph of y = a|x| will be vertically compressed (or "shorter") than the graph of y = |x|, and the arms of the V will be less steep.
If a is negative, the graph of y = a|x| will be a reflection of the graph of y = |x| about the x-axis, resulting in the same shape as y = |x| but flipped upside down

What value of c will complete the square in the expression below to make it a perfect
square trinomial?
x² + 8x + c
Answer:
c = 16
Step-by-step explanation:
We have (a + b)² = a² + 2ab + b²
x² + 8x + c is of the form a² + 2ab + b²
where x² = a²
8x = 2ab
and c = b²
⇒ x² + 8x + c = (x + √c)² which is a perfect square
x² = a² ⇒ x = a
8x = 2ab
⇒ 8x = 2xb
⇒ b = 8x/(2x)
⇒ b = 4
c = b²
⇒ c = 4²
⇒ c = 16
(x + √c)² = (x + √16)²
= (x + 4)²
= x² + 2(x)(4) + 4²
= x² + 8x + 16
Therefore, c = 16 makes the expression a perfect square

1.1 : C - x^2 + x - 2
1.2 : A - 4a^2 - 6b^2 + 12
Step-by-step explanation:
When we have the expression p(x) - q(x), we can substitute those functions in:
(x^2 + 2x - 5) - (x - 3)
We can distribute:
x^2 + 2x - 5 - x + 3
and then combine like terms(2x & -x, -5 & 3)
x^2 + x - 2
This is the same as C.
We can start by distributing:
a^2 - 2b^2 + 3 - 4b^2 + 5 + 3a^2 + 4
Now, we can combine all the a^2 terms(a^2 & 3a^2):
4a^2 - 2b^2 + 3 - 4b^2 + 5 + 4
Then, we can combine the b^2 terms(-2b^2 & -4b^2):
4a^2 - 6b^2 + 3 + 4 + 5
and lastly, all the constants:
4a^2 - 6b^2 + 12

Damien has more than enough juice to fulfill his requirement of 5 pints. The statement that is true is that Damien has bought more than the required amount of juice in pints.
If Damien needs to find 5 pints of juice, he can buy 3 quarts of juice. One quart contains 2 pints, so 3 quarts would contain 6 pints. He has bought a total of 6 pints, which is 1 pint more than what he needed.
This means that Damien can use the extra pint of juice for other purposes or store it for later use. It is important to note that when converting measurements,
