The solution is the length of the rectangle is 250 m and the width of the rectangle is 500 m
The dimensions of the rectangle to have the maximum area with a 1000m fencing will be 250m x 500m
What is the Area of a Rectangle?
The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle
Area of Rectangle = Length x Width
Given data ,
Let the total fencing available be = 1000m
The number of sides of the rectangle that are paddock = 3 sides
The fourth side is an existing straight water
Now , let the area of the rectangle be = A
Now , the derivative of A should be = 0 , for it to have the maximum area
So ,
Let the length of the rectangle be = x
The width of the rectangle = 1000 - 2x
So , The area of the rectangle = Length x Width
Substituting the values in the equation , we get
The area of the rectangle A = x ( 1000 - 2x )
The area of the rectangle A = 1000x - 2x²
Taking derivatives on both sides of the equation with respect to x ,
dA/dx = 1000 - 4x
when dA/dx = 0 , it will have the maximum area
So ,
1000 - 4x = 0
Adding 4x on both sides of the equation , we get
4x = 1000
Divide by 4 on both sides , we get
x = 250 m
So , the length of the rectangle = 250 m
The width of the rectangle = 1000 - 2x
The width of the rectangle = 500 m
Therefore , the dimensions of the rectangle is 250 m x 500 m
Hence , The dimensions of the rectangle to have the maximum area with a 1000m fencing will be 250m x 500m

Write an exponential function in the form y=ab^x that goes through points (0, 14) and (3,896).
The exponential function that goes through the points (0, 14) and (3, 896) is y = 14·3ˣ. This function has a base of 3 and a coefficient of 14.
An exponential function in the form y =abˣ is a function
where y is equal to a multiplied by b raised to the power of x.
To find the function that goes through the points (0, 14) and (3, 896),
We can write the following equation to find the base of the exponential function that goes through the points (0, 14) and (3, 896):
b³ = 896/14
We can then solve for b by taking the cube root of both sides of the equation to get:
b = 3
Now that we know the base of the function, we can use the point (0, 14) to find the value of the coefficient a.
Since the x-value of this point is 0, we can plug 0 in for x in the exponential function y=abˣ to get:
y = ab⁰ = a
Since the y-value of the point (0, 14) is 14, we can set this equal to a to solve for the value of a:

The maximum value of f(x,y) on the unit of circle is [tex]\frac{48 \sqrt{21}}{2,401}[/tex].
The full question is in the attachment. From the unit circle
x² + y² = 1y² = 1 - x²Substitute to f(x,y)
f(x,y) = x³y⁴ = x³ (y²)² = x³ (1 - x²)²
f(x,y) = x³ (1 - 2x² + x⁴)
f(x,y) = x³ - 2x⁵ + x⁷
df/dx = 3x² - (2 × 5)x⁴ + 7x⁶

Why do we use expression?
To express a mathematical operation symbolically, we employ a mathematical expression.
Describe expression.In mathematics, an expression is a sentence that has at least two terms and an operator in the middle. Expressions may be divided into two categories: numerical expressions, which include simply numbers, and algebraic expressions, which contain both numbers and variables. A mathematical expression consists of two parts: terms and operator, where terms refer to variables and integers. It is referred to as a constant term if an expression just contains numbers, and it is known as a coefficient if it also contains numbers and a variable.
Why do we express ourselves?We utilize expressions to symbolically represent any mathematical activity as well as mathematical models. The specifics of our computation, for instance, can be succinctly represented in terms of two or more mathematical terms. We can identify unknown numbers with the equal sign, allowing us to resolve difficult issues. In real life, we utilize expressions to figure out how much we make and spend, how quickly things change, how long it will take to go a certain distance, and other things. When calculating the rate of change, we use the differentiated term dy/dx. When calculating speed, time, and distance, as well as time and speed, we employ equations with variables.

Does the triangle inequality theorem apply to all equilateral triangles?
in the xy plane, the circles with equations (x-3) + y = 11 and (x+2) + y = r are externally tangent what is the value or r ?
let me know if you know man
In the XY plane, the circles with equations (x-3) + y = 11 and (x+2) + y = r are externally tangent. the value of r is -6.
What is tangent?Generally, To find the value of r, we can start by solving for the centers and radii of the two circles.
The equation of the first circle is of the form (x - h)² + (y - k)² = r², where (h, k) is the center of the circle and r is the radius. We can rewrite the equation of the first circle as (x - 3)² + y² = 11², so the center of the circle is (3, 0) and the radius is 11.
The equation of the second circle is also of the form (x - h)₂ + (y - k)₂ = r². We can rewrite the equation of the second circle as (x + 2)² + y² = r², so the center of the circle is (-2, 0) and the radius is r.
Since the two circles are externally tangent, the distance between their centers is equal to the sum of their radii. Therefore, the distance between the centers is equal to 11 + r. We can use the distance formula to find the distance between the centers:
distance = √((h₂ - h₁)^2 + (k₂ - k₁)²)
Plugging in the coordinates of the centers, we get:
distance = √((-2 - 3)^2 + (0 - 0)^2) = √(5^2 + 0^2) = √(25) = 5
Since the distance between the centers is equal to the sum of the radii, we can set up the equation:
5 = 11 + r
Solving for r, we get:
r = 5 - 11 = -6
Therefore, the value of r is -6.

What is the inverse of 7 mod 11?
The inverse of 7 modulo 11 is 4, which means that 4 multiplied by 7 gives a number congruent to 1 (mod 11). This means that 4 is the number that when multiplied by 7 gives a remainder of 1 when divided by 11.
In modular arithmetic, the inverse of a number is the number that when multiplied by the original number gives a result that is congruent to 1 (modulus). For example, if we take the modulus of 11 as an example, then the inverse of 7 modulo 11 is 4, since 7*4 = 28 ≡ 1 (mod 11). This means that 4 is the number that when multiplied by 7 gives a remainder of 1 when divided by 11. The inverse of a number modulo a given modulus can be calculated using the Extended Euclidean algorithm. This algorithm allows us to find the inverse of a number modulo a given modulus by solving a series of equations and using the result to calculate the inverse. For example, in the case of 7 mod 11, the Extended Euclidean algorithm gives us the result 4, which is the inverse of 7 mod 11.
11 = 7*1 + 4
7 = 4*1 + 3
4 = 3*1 + 1

The FLHS gil's basketball team won x games so far this season. The FLHS boy's basketball team won one more than twice as many games. Altotoguether, they won 226 games. How many games did each team win ?
The girl's basketball team won 75 games and the boy's basketball team won 151 games.
Let's assume the number of games the girl's basketball team won "g," and the number of games the boy's basketball team won "b."
We know that the total number of games won by both teams is 226, so we can set up our first equation as follows:
g + b = 226
We also know that the boy's basketball team won one more than twice as many games as the girl's basketball team. We can represent this as follows:
b = 2g + 1
Now we have two equations and two unknown values, so we can solve for g and b using algebra. Let's substitute the second equation into the first equation to eliminate one of the unknowns:
g + (2g + 1) = 226
This simplifies to:
3g + 1 = 226
Subtracting 1 from both sides gives us:
3g = 225
Dividing both sides by 3 gives us:
g = 75
Now that we know the value of g, we can substitute it back into the second equation to solve for b:
b = 2 x 75 + 1 = 151
Therefore, the girl's basketball team won 75 games and the boy's basketball team won 151 games.

How do you find a discriminant for a 2x2 matrix?
The discriminant of a 2x2 matrix is equal to the determinant of the matrix squared. The determinant is calculated by subtracting the product of the two diagonal elements from the product of the two off-diagonal elements
To find the discriminant of a 2x2 matrix, first calculate the determinant of the matrix. The discriminant is then equal to the determinant of the matrix squared.
For example, consider the 2x2 matrix:
A = [a b]
[c d]
The determinant of A is equal to (ad - bc). The discriminant of A is then equal to (ad - bc)^2.

H(x)= 3x^4+2x—5/x+9x^3-7, is it a polynomial? If so write in standard form, degree, type, and leading coefficient.
The function H(x) = 3x⁴ + 2x — 5/x + 9x³ - 7 is not a polynomial function
What is a polynomial function?A polynomial function is a function in an equation, such as the quadratic equation, cubic equation, etc., that only uses non-negative integer powers or only positive integer exponents of a variable.
A polynomial with an exponent of 1 is, for instance, 2x+5.
The given polynomial in standard form is written as
H(x) = 3x⁴ + 2x — 5/x + 9x³ - 7
H(x) = 3x⁴ + 9x³ + 2x - 7 - 5x⁻¹
this shows that on of the term has a negative exponent 5x⁻¹ and hence not a polynomial
the leading coefficient is 3

What is a solution of the inequality 3x 2y 12?
The resultant answer after solving the given inequality by taking the subject x is x < (12 + 2y)/3.
What is inequality?An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way.
The majority of the time, size comparisons between two digits on the number line are made.
So, we have the inequality:
3x - 2y < 12
Now, solve the inequality by taking x as the subject as follows:
3x - 2y < 12
3x < 12 + 2y
3x/3 < 12/3 + 2y/3
x < (12 + 2y)/3
Therefore, the resultant answer after solving the given inequality by taking the subject x is x < (12 + 2y)/3.
