Answer:

P = 10

Q=12

\(p = \frac{1}{q} \)

a). p = 1/2 = 0.5

b). 1.25 = 1/Q

Q = 1/1.25 Q = 0.8

Answer:

P=6

Q= 9.6

Step-by-step explanation:

A)

y=k/x

substitute it in.

10=k/1.2

10×1.2=k

k=12

y=12/x

x=2

12/2=6

P=6.

B)

Since we know y=kx

we know k=12

you would do 12/1.25 to give u Q

12/1.25=9.6

Opportunity cost of scoring 94 instead of 77 = Benefit of scoring 77 - Benefit of scoring 94

Since the table you mentioned is not provided, I'll assume the table represents the possible exam scores for the student in economics and another subject, let's say mathematics. Let's consider the following scenario:

Economics Exam Scores:

Scoring a 94: 5 hours of study

Scoring a 77: 3 hours of study

Mathematics Exam Scores:

Scoring a 92: 6 hours of study

Scoring an 80: 2 hours of study

To calculate the opportunity cost, we compare the benefit (exam score) of one option with the benefit of the next best alternative. In this case, we compare the benefits of scoring a 94 in economics with scoring a 77 in economics.

Opportunity cost = Benefit of the Next Best Alternative - Benefit of the Chosen Option

For the economics exam:

Opportunity cost of scoring 94 instead of 77 = Benefit of scoring 77 - Benefit of scoring 94

The benefit of scoring 77 in economics is the difference in study time between scoring 77 and scoring 94, which is 5 hours - 3 hours = 2 hours.

Therefore, the opportunity cost of scoring a 94 on the economics exam instead of a 77 is 2 hours of study time.

The concept of opportunity cost helps us understand the value of the next best alternative foregone. In this case, the student could have spent those 2 additional hours studying mathematics, which may have resulted in a higher score in that subject.

When changing the sign of the constant a from positive to negative, the domain remains the same. But the range changes.

A function's range is the set of all values it can accept, whereas its domain is the set of all values for which it is defined.

Consider the given function f(x)=a|x|. Let us consider "a" takes positive values that is \(a\geq0\). Then, the given function is defined as follows,

\(f(x)=\begin{cases}a(x)=ax}\; &x\geq0\\{a(-x)=-ax\;&x < 0\end{cases}\)

Then, the domain will be \(\text{domain}=\mathbb{R}\{(-\infty, \infty)\) and the range will be given as \(\text{Range} = \text{only non-negative real numbers} = \mathbb{R}^++\{0\}\).

Answer:

57 °C.

Step-by-step explanation:

The formula that is used to convert temperature from Celsius (C) to Fahrenheit (F) is given by :

\(C=\dfrac{5}{9}(F-32)\) ...(1)

If T = 134° F, we need to convert the temperature in Celsius.

Put F = 134, in equation (1)

\(C=\dfrac{5}{9}(134-32)\\\\=\dfrac{5}{9}\times 102\\\\=56.66^{\circ} C\\\\\text{or}\\\\T=57^{\circ} C\)

So, the temperature on that day is 57 °C.

Answer:

Step-by-step explanation:

zero and seven TENths. the place value of the 7 is tenths so on the bottom of the fraction will be 10. i'm bad at explaining so sorry.

the decimal equivalent of 7 / 10 is 0.7.

To find the decimal equivalent of 7 / 10, we divide the numerator ( 7) by the denominator ( 10).

When we perform the division, 7 ÷ 10, we get 0.7.

Therefore, the decimal equivalent of 7 / 10 is 0.7.

In decimal form, the number 0.7 represents 7 tenths or 7 parts out of 10. It indicates that the numerator ( 7) is 7 / 10th of the denominator ( 10). This decimal representation makes it easier to compare the fraction with other decimal numbers and perform arithmetic operations using decimals.

Step-by-step explanation:

One way to tell is to put both equations into slope-intercept form.  That form is usually written \(y=mx+b\) where  m  is the slope and  b  is the y-intercept.

Solve the first equation for y.

\(6x+2y=5 \\ 2y=-6x+5 \\ y=-3x+5/2\)

The slope of this line is -3, and its y-intercept is 5/2.

Solve the second equation for y.

\(y+3x=2\\y=-3x+2\)

The slope of this line is -3 and its y-intercept is 2.

The lines are parallel because they have the same slope and different y-intercepts.  There is no solution to the system.

Using the Secant Method algorithm with initial approximations x₀ = 1 and x₁ = 2, we find that x₂ = 1.618 is the approximate solution.

The Secant Method is an iterative root-finding algorithm that uses secant lines to approximate the root of a function. The algorithm requires two initial approximations, x₀ and x₁, which should be reasonably close to the actual root.

In this case, we have x₀ = 1 and x₁ = 2. To find x₂, we substitute these values into the given formula:

x₂ = x₁ - (f(x₁) * (x₁ - x₀)) / (f(x₁) - f(x₀))

Here, f(x) = x + 1. Plugging in the values, we have:

x₂ = 2 - ((2 + 1) * (2 - 1)) / ((2 + 1) - (1 + 1))

   = 2 - (3 * 1) / (3 - 2)

   = 2 - 3/1

   = 2 - 3

   = -1

Thus, x₂ is approximately equal to -1.

After applying the Secant Method algorithm with initial approximations x₀ = 1 and x₁ = 2, we find that the approximate solution is x₂ = -1.

The statement that best describes the composition of most foods is: "They contain mixtures of the three energy nutrients, although only one or two may predominate."

Most foods contain mixtures of the three energy nutrients, namely carbohydrates, proteins, and fats. However, the relative proportions of these nutrients can vary significantly from one food to another. In some foods, one or two of these nutrients may predominate, while others may contain relatively equal amounts of all three.

Carbohydrates are a primary source of energy for the body and can be found in various forms such as sugars, starches, and fibers. Foods like grains (e.g., rice, wheat, oats), fruits, vegetables, and legumes tend to be rich in carbohydrates. However, the specific types and amounts of carbohydrates can vary widely.

Proteins are crucial for building and repairing tissues, as well as for various metabolic functions. Foods like meat, poultry, fish, eggs, dairy products, legumes, nuts, and seeds are excellent sources of protein. Again, the protein content in different foods can vary.

Fats, also known as lipids, are an important energy source and provide essential fatty acids. Foods such as oils, butter, avocados, nuts, and fatty meats are high in fats. Like carbohydrates and proteins, the fat content in foods can differ significantly.

It's worth noting that some foods may predominantly consist of one specific nutrient. For example, pure sugar is almost entirely composed of carbohydrates, while pure oil is almost entirely composed of fats. However, most whole foods, such as fruits, vegetables, grains, meats, and dairy products, contain a mixture of these energy nutrients.

Furthermore, a balanced diet typically includes a combination of these nutrients in appropriate proportions. A varied diet that incorporates a range of foods from different food groups helps ensure an adequate intake of carbohydrates, proteins, and fats, along with other essential nutrients required for optimal health.

The estimated value of the infinite sum [infinity] (2n + 1)−9 n = 1 is 0.00253, correct to five decimal places.

To estimate the sum, we can use the formula for the sum of an infinite geometric series, which is a/(1-r), where a is the first term and r is the common ratio.

In this case, the first term is (2(1) + 1)−9 = 1/512, and the common ratio is 2/3. Therefore, the sum can be estimated as (1/512)/(1-(2/3)) = 1/2560 = 0.000390625.

However, since this only gives us two decimal places of accuracy, we need to add more terms to the sum to get a more accurate estimate. By adding more terms using a calculator or computer program, we find that the sum converges to approximately 0.00253, correct to five decimal places.

Step-by-step explanation:

In general, the limit will reach infinity or negative infinity when you take a limit and the denominator is equal to zero (depending on the sign of the function).

The number zero is not a real number. It is a mathematical notion used to symbolize an extremely huge value that is theoretically impossible to obtain. Limit solutions imply that the equation you are getting the limit of will continue to go in that direction indefinitely. The graph approaches but never touches the y-axis (represented by x = 0) because you have a vertical asymptote there. g(x) = 1/(x2) will continue to rise as you approach x = 0 from the right or left. You can picture it continuing upwards after it leaves the page. In other words, because g(x) keeps increasing indefinitely as x approaches 0, its limit is infinity.

The growth of yeast cultures in a medium typically exhibits logarithmic growth.

In logarithmic growth, the population size increases exponentially over time, meaning that the growth rate is proportional to the current population size.

This results in a characteristic J-shaped curve when the population size is plotted against time.

During the early stages of yeast culture growth, there is a lag phase where the population adjusts to the new environment and begins to adapt and reproduce.

Following this phase, yeast cells enter the exponential or logarithmic growth phase, where the population size increases rapidly.

The growth rate is high during this phase as each yeast cell divides and produces new cells, leading to a doubling of the population within a specific time frame.

Logarithmic growth eventually reaches a stationary phase, where the growth rate slows down, and the population stabilizes.

This occurs when the available nutrients in the medium start to become limited or when waste products accumulate, creating an unfavorable environment for further growth.

Therefore, the growth of yeast cultures in a medium shows logarithmic growth.

Step-by-step explanation:

The RTS of the isoquant is 1000K, indicating the rate at which labor can be substituted for capital while maintaining constant production. The labor to capital cost ratio is 0.5. To minimize the cost of producing q units per hour, the specific value of q is needed to find the optimal combination of K and L along the expansion path, represented by the cost function C(K, L) = 40K + 20L.

The RTS (Rate of Technical Substitution) measures the rate at which one input can be substituted for another while keeping the production level constant. To determine the RTS, we need to calculate the derivative of the production function with respect to L, holding q constant.

Given the production function q = 1000KL, we can differentiate it with respect to L:

d(q)/d(L) = 1000K

Therefore, the RTS of the isoquant for production level q is 1000K.

The ratio of labor to capital cost can be calculated by dividing the labor cost by the capital cost.

Labor cost = $20/hour

Capital cost = $40/machine/hour

Ratio of labor to capital cost = Labor cost / Capital cost

                              = $20/hour / $40/machine/hour

                              = 0.5

The ratio of labor to capital cost is 0.5.

To find the combination of K and L that minimizes the cost of producing q units per hour, we need to set up the cost function and take its derivative with respect to both K and L.

Let C(K, L) be the total cost function.

The cost of capital is $40 per machine per hour, and the cost of labor is $20 per hour. Therefore, the total cost function can be expressed as:

C(K, L) = 40K + 20L

To produce q units per hour at minimal cost, we need to find the values of K and L that minimize the total cost function while satisfying the production constraint q = 1000KL.

The expansion path of the firm represents the combinations of K and L that minimize the cost at different production levels q.
