Answer:

\(\frac{8}{9}\)

Step-by-step explanation:

We have to create 2 fractions with the repeating number placed after the decimal point.

let x = 0.88.... → (1) ( multiply both sides by 10 )

10x = 8.88.... → (2)

Subtract (1) from (2), eliminating the repeating decimal

9x = 8 ( divide both sides by 9 )

x = \(\frac{8}{9}\)

Thus 0.888..... = \(\frac{8}{9}\)

The mathematical procedure for decomposing a complex waveform into simpler waveforms is known as Fourier analysis. It allows for the identification of the individual frequency components that contribute to the overall pattern.

Fourier analysis, named after the French mathematician Jean-Baptiste Joseph Fourier, is a fundamental technique used in many fields, including signal processing, physics, and engineering. It is based on the concept that any complex waveform can be represented as a combination of simpler sinusoidal waveforms. These simpler waveforms are characterized by their frequency, amplitude, and phase.

The procedure involves decomposing a complex waveform into its constituent frequencies by applying the Fourier transform. The Fourier transform converts the waveform from the time domain to the frequency domain, revealing the underlying frequency components. By analyzing the resulting spectrum, which shows the amplitude and phase of each frequency component, one can determine the simpler waveforms that make up the original complex pattern.

Fourier analysis has numerous applications, such as analyzing sound waves, image processing, and data compression. It enables us to better understand and manipulate complex signals by breaking them down into their fundamental building blocks.

In the production possibilities framework, economic growth is depicted by the PPF (Production Possibilities Frontier) shifting rightward (away from the origin). This indicates an increase in the economy's capacity to produce goods and services.

The production possibilities framework represents the different combinations of goods and services that an economy can produce given its resources and technology.

The PPF is typically depicted as a curve, showing the trade-off between producing different goods or allocating resources between different sectors of the economy.

When the PPF shifts rightward, it means that the economy's production capacity has increased.

This can happen due to various factors such as technological advancements, increased capital investment, improved infrastructure, or an expansion of the labor force.

As a result, the economy can produce more goods and services at each point along the PPF.

The shift of the PPF rightward indicates economic growth because it signifies an expansion of the production possibilities.

With a larger production capacity, the economy has the potential to achieve higher levels of output, leading to increased living standards, higher incomes, and greater overall economic prosperity.

On the other hand, if the PPF became a straight line or shifted leftward (toward the origin), it would indicate a decrease in the economy's production capacity or a decline in resources or technology.

In such cases, the economy would experience a contraction in its production possibilities and potentially face challenges in meeting the needs and wants of its population.

Therefore, the correct answer is that economic growth in the production possibilities framework is depicted by the PPF shifting rightward (away from the origin).

Step-by-step explanation:

Mate's car can travel approximately 5 more minutes per gallon of gas compared to Jenna's car.

To determine how many more minutes Mate's car can travel per gallon of gas compared to Jenna's car, we would need additional information about the fuel efficiency or miles per gallon (MPG) for each car.

Fuel efficiency is typically measured in terms of miles per gallon, indicating the number of miles a car can travel on a gallon of gas.

To calculate the difference in travel time, we would also need to know the average speed at which the cars are traveling.

Once we have the MPG values for Mate's car and Jenna's car, we can calculate the difference in travel time per gallon of gas by considering their respective fuel efficiencies and average speeds.

If Mate's car has a fuel efficiency of 30 MPG and Jenna's car has a fuel efficiency of 25 MPG, we can calculate the difference in travel time by comparing the distances they can travel on a gallon of gas.

Let's assume both cars are traveling at an average speed of 60 miles per hour.

For Mate's car:

Travel time = Distance / Speed

= (30 miles / 1 gallon) / 60 miles per hour

= 0.5 hours or 30 minutes.

For Jenna's car:

Travel time = Distance / Speed

= (25 miles / 1 gallon) / 60 miles per hour

= 0.4167 hours or approximately 25 minutes.

Without specific information about the MPG values and average speeds of the cars, it is not possible to provide an accurate answer regarding the difference in travel time per gallon of gas between Mate's car and Jenna's car.

If a prism has a base that is a regular \(n\)-gon, then the prism will have \(2n\) vertices, \(3n\) faces, and \(3n\) edges. Here, each face is a regular polygon with \(n\) sides.

Consider a prism whose base is a regular polygon with \(n\) sides.In this prism, each face of the polygon is extended to a rectangle and the height of this prism is the perpendicular distance between the two rectangles that have the same side as the polygon’s sides.

Let's assume the height of the prism to be \(h\). The polygon has \(n\) vertices, faces, and edges. So, there will be \(2n\) vertices and \(2n\) rectangular faces.

Each rectangular face has two edges that are equal to the side of the polygon and two edges that are equal to the height of the prism.

So, there will be \(2n\) edges with the length of the polygon's sides and another \(n\) edges with the length of the prism’s height.Thus, the prism will have \(2n\) vertices, \(3n\) faces, and \(3n\) edges.

You would need to wait approximately 51.33 years from now to grow your initial investment of $39,000 to $174,000 at an interest rate of 10% per year.

To calculate the number of periods (years) required to grow an initial investment to a desired future value, we can use the formula for compound interest:

FV = PV * \((1 + r)^n\)

Where:

FV is the future value

PV is the present value (initial investment)

r is the interest rate per period

n is the number of periods

In this case:

PV = $39,000

FV = $174,000

r = 10% per year

Let's calculate the number of periods (years):

FV = PV * \((1 + r)^n\)

174,000 = 39,000 * \((1 + 0.10)^n\)

Divide both sides by 39,000:

4.4615 = \((1.10)^n\)

Take the logarithm of both sides to solve for n:

log(4.4615) = n * log(1.10)

n ≈ log(4.4615) / log(1.10)

n ≈ 2.1270 / 0.0414

We have to find the height of the mountain and the distance between A and B.

The point on the surface that ensures the tangent plane contains (3,0,0) is (1/2, 0, 1/4).To find a point on a surface that ensures the tangent plane contains the point (3,0,0), we need to use the following steps:

Find the gradient vector of the surface at a general point (x,y,z).

Set the gradient vector equal to the normal vector of the tangent plane passing through (3,0,0). Since the normal vector of the tangent plane is perpendicular to the plane, it must be orthogonal to the gradient vector.

Solve the resulting system of equations for x, y, and z to find the specific point on the surface that satisfies the condition.

For example, let's consider the surface defined by the equation z = x^2 + y^2. The gradient vector of this surface is given by <2x, 2y, -1>. Setting this equal to the normal vector of the tangent plane passing through (3,0,0), which is <1,0,0>, gives us the following system of equations:

2x = 1

2y = 0

-1 = 0

Solving for x and y, we get x = 1/2 and y = 0. Plugging these values into the original equation of the surface, we get z = (1/2)^2 + 0^2 = 1/4. Therefore, the point on the surface that ensures the tangent plane contains (3,0,0) is (1/2, 0, 1/4).

The consumption bundle that will not be the consumer's choice, given the assumptions of choosing the optimal bundle, is option B) 30 snacks and 12 meals. To determine the optimal consumption bundle, we need to consider the consumer's budget constraint and maximize their utility.

Given that the price of snacks is $4 and the price of meals is $10, and the consumer has $240 remaining on their meal card, we can calculate the maximum number of snacks and meals that can be purchased within the budget constraint.

For option A) 5 snacks and 20 meals, the total cost would be $4 × 5 + $10 × 20 = $200. Since the consumer has $240 remaining, this bundle is feasible.

For option B) 30 snacks and 12 meals, the total cost would be $4 × 30 + $10 × 12 = $240. This bundle is on budget constraint, but it may not be the optimal choice since the consumer could potentially consume more meals for the same cost.

For option C) 20 snacks and 16 meals, the total cost would be $4 × 20 + $10 × 16 = $240. This bundle is also on budget constraint.

Since options A, C, and D are all feasible within the budget constraint, the only bundle that will not be the consumer's choice is option B) 30 snacks and 12 meals. The consumer could achieve a higher level of utility by reallocating some snacks to meals while staying within the budget constraint. Therefore, the correct answer is option B.

Answer:

Area of the rectangle = 286 mm^2

Step-by-step explanation:

Mathematically, area of rectangle = height * base

We only have the base, and not the length here so we need to get the length first.

Mathematically, from the perimeter

P = 2(l + b)

74 = 2(26 + l)

74 = 52 + 2l

2l = 74-52

2l = 22

l = 22/2 = 11 mm

a) The pοints οn the curve with x-cοοrdinate 1 are (1, 3) and (1, -2). The equatiοn οf the tangent line at (1, -2) is y = (3/2)x - 5/2.

b) The x-cοοrdinate οf each pοint οn the curve where the tangent line is vertical is apprοximately ±1.443.

A curve is defined as a smοοthly- flοwing cοntinuοus line that has bent. It dοes nοt have any sharp turns. The way tο identify the curve is that the line bends and changes its directiοn at least οnce.

a) Tο find all pοints οn the curve whοse x-cοοrdinate is 1, we substitute x = 1 intο the equatiοn and sοlve fοr y:

1 * y² - 1³ * y = 6

y² - y = 6

y² - y - 6 = 0

Factοring the quadratic equatiοn, we have:

(y - 3)(y + 2) = 0

Setting each factοr equal tο zerο, we find twο pοssible values fοr y:

y - 3 = 0 --> y = 3

y + 2 = 0 --> y = -2

Therefοre, the pοints οn the curve with x-cοοrdinate 1 are (1, 3) and (1, -2).

Tο find the equatiοn οf the tangent line at each οf these pοints, we need tο find the derivative dy/dx and evaluate it at each pοint.

Differentiating the equatiοn οf the curve implicitly with respect tο x, we get:

2xy * dy/dx - 3x² * y - x³ * dy/dx = 0

Rearranging the terms and sοlving fοr dy/dx, we have:

dy/dx * (2xy - x³) = 3x² * y

dy/dx = (3x² * y) / (2xy - x³)

At the pοint (1, 3):

dy/dx = (3 * 1² * 3) / (2 * 1 * 3 - 1³) = 9 / 5

Using the pοint-slοpe fοrm οf a line, we can write the equatiοn οf the tangent line at (1, 3) as:

y - 3 = (9/5)(x - 1)

y = (9/5)x - 6/5

At the pοint (1, -2):

dy/dx = (3 * 1² * -2) / (2 * 1 * -2 - 1³) = -6 / (-4) = 3/2

The equatiοn οf the tangent line at (1, -2) is:

y - (-2) = (3/2)(x - 1)

y = (3/2)x - 5/2

b) Tο find the x-cοοrdinate οf each pοint οn the curve where the tangent line is vertical, we need tο find the x-values where the derivative dy/dx is undefined οr infinite.

Frοm the expressiοn fοr dy/dx derived earlier:

dy/dx = (3x² * y) / (2xy - x³)

The derivative will be undefined οr infinite when the denοminatοr is equal tο zerο:

2xy - x³ = 0

x(2y - x²) = 0

This equatiοn will hοld true when x = 0 οr 2y - x² = 0.

Fοr x = 0, substituting intο the οriginal equatiοn:

0 * y² - 0³ * y = 6

0 - 0 = 6 (which is nοt true)

Therefοre, we can exclude x = 0 as a valid sοlutiοn.

Fοr 2y - x² = 0, we can substitute 2y fοr x² in the οriginal equatiοn:

xy² - (2y)³ * y = 6

xy² - 8y³ = 6

y(xy² - 8y²) = 6

This equatiοn dοes nοt prοvide a straightfοrward sοlutiοn fοr the x-cοοrdinate when the tangent line is vertical. Tο determine the x-cοοrdinate, yοu can either sοlve this equatiοn numerically οr graphically.

Using numerical methοds, we can apprοximate the x-cοοrdinate fοr the vertical tangent line. Substituting different values οf y intο the equatiοn, we find that when y ≈ 1.042, the equatiοn is satisfied. Plugging this value οf y back intο 2y - x² = 0, we can sοlve fοr the cοrrespοnding x-cοοrdinate:

2(1.042) - x² = 0

2.084 - x² = 0

x² = 2.084

x ≈ ±1.443

The derivative of F(x) is F'(x) = 2x⁷ - 7x³ - 3x + 3.

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.

To find the derivative of the given function F(x), we will apply the fundamental theorem of calculus and differentiate the integral with respect to x.

Let's compute F'(x):

F(x) = ∫[x² to x] (-t³ + 3t + 3) dt

To differentiate the integral with respect to x, we'll use the Leibniz integral rule:

F'(x) = d/dx ∫[x² to x] (-t³ + 3t + 3) dt

According to the Leibniz integral rule, we have to apply the chain rule to the upper limit of the integral.

F'(x) = (-x³ + 3x + 3) dx/dx - (-(x²)³ + 3(x²) + 3) d(x²)/dx   [applying the chain rule to the upper limit]

F'(x) = (-x³ + 3x + 3) - (-x⁶ + 3x² + 3) (2x)  [using the power rule for differentiation]

F'(x) = -x³ + 3x + 3 + 2x⁷ - 6x³ - 6x

F'(x) = 2x⁷ - 7x³ - 3x + 3

Therefore, the derivative of F(x) is F'(x) = 2x⁷ - 7x³ - 3x + 3.
