Step-by-step explanation:

Answer: $7.65 for a dozen/12

Step-by-step explanation: 2.55 x 3

The expression "raise b to the 2nd power" means to multiply b by itself, which can be written as \(b^2\). The expression \((b^2)/8\) represents this quotient.

When we say "raise b to the 2nd power", it means we are squaring b, which is equivalent to multiplying b by itself. So, \(b^2\) represents the result of multiplying b by itself.

Next, the phrase "find the quotient of the result and 8" means we need to divide \(b^2\) by 8. Dividing \(b^2\) by 8 gives us the expression \((b^2)/8\), which represents the quotient we are looking for. We do not simplify the expression any further, because the instructions say to "not simplify any part of the expression."

So, \((b^2)/8\) is the final answer. This expression is still in fraction form, and it can be useful to keep it in this form if we are using it to solve a larger problem or if we want to keep the answer as precise as possible. If we want to convert it to decimal form, we can use a calculator to divide \(b^2\) by 8.

Answer:

V - 1099.55742876

SA - 769.690200129

Step-by-step explanation:

The volume of a cone is denoted by the formula:

V = 1/3 * h * pi * r^2

We can substitute in the values we are given:

V = 1/3 * 10.5 * pi * 10^2

V = 3.5 * 100 * pi

V = 350pi

This is about: 1099.55742876

The formula for the surface area of a cone is:

SA = pi * r^2 + pi * r * s

We can substitute what we have:

SA = pi * 10^2 + pi * 10 * 14.5

SA = 100 pi + 145 pi

SA = 245 pi

This is about: 769.690200129

Statistics computed for larger random samples tend to be less variable compared to statistics computed for smaller random samples.

This statement is based on the concept of the Central Limit Theorem (CLT) in statistics. According to the CLT, as the sample size increases, the distribution of the sample mean approaches a normal distribution regardless of the shape of the population distribution. This means that the variability of the sample mean decreases as the sample size increases.

The variability of a statistic is commonly measured by its standard deviation or variance. When working with larger random samples, the individual observations have less impact on the overall variability of the statistic. As more data points are included in the sample, the effects of outliers or extreme values tend to diminish, resulting in a more stable and less variable estimate.

In practical terms, this implies that estimates or conclusions based on larger random samples are generally considered more reliable and accurate. Researchers and statisticians often strive to obtain larger sample sizes to reduce the variability of their results and increase the precision of their statistical inferences.

Answer:

Step-by-step explanation:

a) To obtain the potential pressure drop in the wellbore, we can use the hydrostatic pressure equation.

The potential pressure drop is equal to the pressure gradient multiplied by the length of the wellbore. The pressure gradient can be calculated using the equation: Pressure gradient = (density of oil × acceleration due to gravity) × sin(θ), where θ is the deviation angle of the wellbore from horizontal flow. In this case, the pressure gradient would be (48 lbm/ft^3 × 32.2 ft/s^2) × sin(15°). Multiplying the pressure gradient by the wellbore length of 6,000 ft gives the potential pressure drop.

b) To determine the frictional pressure drop in the wellbore, we can use the Darcy-Weisbach equation. The Darcy-Weisbach equation states that the pressure drop is equal to the friction factor multiplied by the pipe length, density, squared velocity, and divided by the pipe diameter. However, to calculate the friction factor, we need the Reynolds number. The Reynolds number can be calculated as (density × velocity × diameter) divided by the oil viscosity. Once the Reynolds number is known, the friction factor can be determined. Finally, using the friction factor, we can calculate the frictional pressure drop.

c) To calculate the in-situ oil velocity, we need to consider the total volume of the pipe, including both oil and gas. The total pipe volume is calculated as the pipe cross-sectional area multiplied by the wellbore length. Subtracting the gas volume from the total volume gives the oil volume. Dividing the oil volume by the total time taken by the oil to flow through the pipe (converted to seconds) gives the average oil velocity.

d) The flow regime of the two-phase flow can be determined based on the oil and gas mixture properties and flow conditions. Common flow regimes include bubble flow, slug flow, annular flow, and mist flow. These regimes are characterized by different distribution and interaction of the oil and gas phases. To determine the specific flow regime, various parameters such as gas and liquid velocities, mixture density, viscosity, and surface tension need to be considered. Additional information would be required to accurately determine the flow regime in this scenario.

When the second derivative of a function equals zero, it indicates a possible point of inflection or a critical point where the concavity of the function changes. It is a significant point in the analysis of the function's behavior.

The second derivative of a function measures the rate at which the slope of the function is changing. When the second derivative equals zero at a particular point, it suggests that the function's curvature may change at that point. This means that the function may transition from being concave upward to concave downward, or vice versa.

Mathematically, if the second derivative is zero at a specific point, it is an indication that the function has a possible point of inflection or a critical point. At this point, the function may exhibit a change in concavity or the slope of the tangent line.

Studying the second derivative helps in understanding the overall shape and behavior of a function. It provides insights into the concavity, inflection points, and critical points, which are crucial in calculus and optimization problems.

When the second derivative of a function equals zero, it indicates a critical point in the function, which can be a maximum, minimum, or an inflection point.

The second derivative of a function measures the rate at which the slope of the function is changing. When the second derivative equals zero, it indicates a critical point in the function. A critical point is a point where the function may have a maximum, minimum, or an inflection point.

To determine the nature of the critical point, further analysis is required. One method is to use the first derivative test. The first derivative test involves examining the sign of the first derivative on either side of the critical point. If the first derivative changes from positive to negative, the critical point is a local maximum. If the first derivative changes from negative to positive, the critical point is a local minimum.

Another method is to use the second derivative test. The second derivative test involves evaluating the sign of the second derivative at the critical point. If the second derivative is positive, the critical point is a local minimum. If the second derivative is negative, the critical point is a local maximum. If the second derivative is zero or undefined, the test is inconclusive.

You need to look carefully at the inequality signs in the first question. Thew amount of pillowcases she buys needs to be AT LEAST 10, but the maximum amount of money she can spend is 100. So I think C would be the best answer.

Answer:

C and then D

Step-by-step explanation:

s = number of small pillow cases

l = number of large pillow cases

s + l >= 10 (but at least 10 cases)

8s + 12l <= 100 (cannot spend more than $100)

remember, every small pillow case costs $8, every large $12.

so, answer C.

8×12 + 3×8 = $120

so, that's not possible.

4×12 + 7×8 = 48 + 56 = $104

so, that's not possible.

6×12 + 3×8 = 72 + 24 = $96

that would work but

6 + 3 = 9 which is not >= 10

so, that's not possible.

2×12 + 9×8 = 24 + 72 = $96

2 + 9 = 11

The spider's movement is an illustration of a parabola.

(a) The equation

The spider passes through the origin.

So, we have:

\(\mathbf{(x,y) = (0,0)}\)

The spider jumps to a maximum height of 20mm, midway 160mm.

So, the vertex is:

\(\mathbf{(h,k) = (80,20)}\)

The equation of a parabola is:

\(\mathbf{y = a(x - h)^2 + k}\)

So, we have:

\(\mathbf{0 = a(0 - 80)^2 + 20}\)

\(\mathbf{0 = 6400a + 20}\)

Subtract 20 from both sides

\(\mathbf{6400a =- 20}\)

Solve for a

\(\mathbf{a =- \frac{1}{320}}\)

Substitute \(\mathbf{a =- \frac{1}{320}}\) and \(\mathbf{(h,k) = (80,20)}\) in \(\mathbf{y = a(x - h)^2 + k}\)

\(\mathbf{y = -\frac{1}{320}(x - 80)^2 + 20}\)

(b) The focus, directrix and the axis of symmetry

The focus of a parabola is:

\(\mathbf{Focus = (h,k+p)}\)

Where:

\(\mathbf{p = \frac{1}{4a}}\)

So, we have:

\(\mathbf{p = \frac{1}{4\times -1/320}}\)

\(\mathbf{p = -\frac{320}{4}}\)

\(\mathbf{p = -80}\)

So, we have:

\(\mathbf{Focus = (80 , 20-80)}\)

\(\mathbf{Focus = (80 ,-60)}\)

The axis of symmetry is:

\(\mathbf{x = h}\)

So, we have:

\(\mathbf{x = 80}\)

The directrix is:

\(\mathbf{y = k - p}\\\)

So, we have:

\(\mathbf{y = 20+80}\)

\(\mathbf{y = 100}\)
