You have d dollars to buy fence to enclose a rectangular plot of land. the fence for the top and bottom costs $a per foot and for the sides it costs $b per foot.

To find the dimensions of the plot with the largest area.

Total Money = D dollars

Total cost for top and bottom fence = $4(2x)

Total cost for sides fence = $8(2y)

Hence total cost of fencing = 4(2x)+8(2y) = 8x+16y

C = 8x+16y

Given cost (c) = D dollars

D = 8x+16y

Now Area of the plot A = xy

A = xy is optimizing function and D = 8x+16y

= [tex](\frac{D-16y}{8})=x[/tex]

A = [tex]\frac{D-16y}{8}y[/tex]

For A to be maximum [tex]\frac{dA}{dy}=0[/tex]

A = [tex]\frac{D}{8}y-\frac{16}{8}y^{2}[/tex]

[tex]\frac{dA}{dy} = \frac{D}{8}-\frac{16}{8}(2y)[/tex]

[tex]\frac{dA}{dy} = \frac{D}{8}-4y[/tex]

[tex]\frac{dA}{dy} = 0 = \frac{D}{8}-4y=0[/tex]

[tex]\frac{D}{8} = 4y = y = \frac{D}{32}[/tex]

Now [tex]\frac{d^{2}A }{dy^{2}} = -4 = -ve number[/tex]

for y = [tex]\frac{D}{32}[/tex] area is maximum

[tex]x = \frac{D-16y}{8} = \frac{D-16 (\frac{D}{32} )}{8} = \frac{D}{16}[/tex]

The height of the rectangular prism  is 4x+2 unit.

What is  rectangular prism?

A rectangular prism's volume is a measurement of the entire interior volume. Consider a rectangular water-filled container. In this instance, the container's capacity is equal to the maximum amount of water it can hold. A polyhedron known as a prism has the same cross-section along its entire length, equal bases, and flat rectangular side faces. Based on the design of their bases, prisms are categorised. A rectangular prism is within the category of three-dimensional shape. The prism has six faces, all of which are rectangles.

Here the given volume of rectangular prism is,

=> V= 4[tex]x^3+22x^2+10x[/tex] cubic unit

And area of base B = [tex]x^2+5x[/tex] square unit.

Now volume of rectangular prism

=> V= area of base × height

=> 4[tex]x^3+22x^2+10x[/tex]  = [tex]x^2+5x[/tex] × height

=> Height = [tex]\frac{4x^3+22x^2+19x}{x^2+5x}[/tex]

=> Height = [tex]\frac{2x(2x^2+11x+5)}{x(x+5)}[/tex]

=>Height = [tex]\frac{2(2x^2+x+10x+5)}{x+5}[/tex]

=> Height = [tex]\frac{2(x(2x+1)+5(2x+1))}{x+5}[/tex]

=> Height = [tex]\frac{2(2x+1)(x+5)}{x+5}[/tex]

=>Height = 2(2x+1)

=> Height = 4x+2 unit .

Hence height of the rectangular prism is 4x+2 unit.

By using diagonal properties of square, we can prove the area of triangle as a².

A square is a flat object in geometry that has four equal sides and four right angles (90°). An equilateral rectangle is a specific sort of square, while a parallelogram is a special kind of square (an equilateral and equiangular one).

Prove: Area of square = a²

Suppose, there is a square of side length a.

Let, d be the length of each diagonal. We know, both diagonals of square have equal length.

So, d^2 = a^2 + a^2 = 2 * (a^2)

Or, d = a * (√2).

Also, we know that diagonals of a square are perpendicular bisectors.

So, we can consider that the square as four isosceles right angled triangles.

Length of each perpendicular side of every isosceles right angled triangle = (1 / 2) * d = (d / 2).

So, area of each isosceles right angled triangle = (1 / 2) * (d / 2) * (d / 2) = {(d^2) / 8}

Area of the square = 4 * {(d^2) / 8} = {(d^2) / 2}.

Since, d = a * √2; so we put in the above formula, the area becomes equal to that of (a^2).

The exponential function always exceeds the linear function

A mathematical function of form f (x) = an x is an exponential function. where x is a variable and an is the function's base constant The transcendental number e, which is approximately 2.71828, is the most commonly encountered exponential-function base.

An exponential function is distinguished from linear and quadratic functions in that the variable to be solved for is contained within the function's exponent rather than (necessarily) within the base of some exponential expression. Here are some examples:

Linear function: f(x) = 3x - 7: The exponents 1 and 0 are implied here, so f(x) is 3(x^1) - 7(x^0). It is worth noting that x is not a component of either exponent; rather, it is a component of the base of each exponent.

h(x) = 4^(3x + 7):This is an exponential function because the variable x is contained within the exponent in this expression.

As a result, the exponential function always outperforms the linear function.

Justice is using a technique known as chunking.

Short-term memory can function more effectively thanks to chunking, however the quantity of chunks that can be stored efficiently declines as chunk size grows.

Large pieces of information may be divided into smaller bits and then grouped together using relevant information or attributes before being stored in order to improve retention of that information in the short term memory. To establish relational information or similarity between the information to be stored in order to improve retention and recall in the short term memory, information must be broken down before being regrouped.

20 m longer  to walk from A to B along the diagonal of the park than to walk along the edges of the park.

What is rectangle?

Rectangles are quadrilaterals having four right angles in the Euclidean plane of geometry. It can alternatively be described as a parallelogram with a right angle, an equiangular quadrilateral, or a group of triangles with equal angles. A square is a rectangle that has four equal sides.

As given, a park is in the shape of a rectangle and measures length of

40 m and width of 30 m, ∠B = 90°.

So, by Pythagoras theorem,

[tex]AC^2 = AB^2 + BC^2\\AC^2 = (40)^2 + (30)^2\\AC^2 = 1600 + 900\\AC^2 = 2500\\AC = \sqrt{2500}\\ AC = 50[/tex]

So, the distance from A to B along the diagonal is,

AB = AC + BC = 50 + 40 = 90 m

The distance from A to B along with the edges is,

AB = AD + DC + CB = 40 + 30 + 40 = 110 m.

The amount in the bank account at the end of 3 years will be; $5487.5

Simple interest is a method of calculating the interest charge. Simple interest can be calculated as the product of principal amount, rate and time peroid.

Simple Interest = (Principal × Rate × Time) / 100

The amount deposited by Tyler's in the savings account is $5,000

Interest rate = 3.25% annually

Then Calculating the amount in the bank account after 3 years, using the formula;

Simple Interest = (Principal × Rate × Time) / 100

where P = principal invested

R = rate of interest annually

T = number of years amount is invested

So, Simple interest on the principal invested for 3 years=

5,000  x 3.25  x 3/100 = 487.5

The amount in the bank account at the end of 3 years will be;

The total amount Bridget received from her mom will be $6 as she will get extra for cleaning before 6PM.

In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100). A number or ratio that can be expressed as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage therefore refers to a part per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

Based on the image attached, The value of x = 26 and y = 60

Alternate interior angles are the angles formed on the opposite sides of the transversal. The angles that lie on the inner side of the parallel lines but on the opposite sides of the transversal.

And the alternative angle is equal to :

180°So, y° = y° at the alternative side

And so as (3x - 18)° = (3x - 18)° at the alternate side

The angle of a straight  line is  180°

The value of line m is a straight line so it is equal to 180°

So, y + (3x-18) = 180°

As also, the value of straight line (2x + 8)° + y° of the alternate side= 180°

So we have y° + (3x - 18)° = 180 and y° + (2x + 8)° = 180y + 3x = 180 + 18 and y + 2x = 180 - 8y + 3x = 198 and y + 2x = 172

By substituting method to get the value of x and y

when y = 172 - 2x

Substitute to equation 1172 - 2x + 3x = 198x = 198 - 172x = 26°

To find y = y + 2(26) = 172y +52 = 172y = 172 - 52y = 120°
