Answer:

-2-\(\frac{2}{a}\)

Step-by-step explanation:

I broke up the fractions so that it is easier.

\(\frac{1}{a-1}\) - \(\frac{1}{a+1}\) - \(\frac{2}{2a+1}\) - \(\frac{2}{2a-1}\) = (\(\frac{1}{a}\) - \(\frac{1}{1}\)) - (\(\frac{1}{a}\) + \(\frac{1}{1}\)) - (\(\frac{2}{2a}\) + \(\frac{2}{1}\)) - (\(\frac{2}{2a}\) - \(\frac{2}{1}\))

Now I remove the brackets. One plus and one minus make one minus and two minus makes one plus.

(\(\frac{1}{a}\) - \(\frac{1}{1}\)) - (\(\frac{1}{a}\) + \(\frac{1}{1}\)) - (\(\frac{2}{2a}\) + \(\frac{2}{1}\)) - (\(\frac{2}{2a}\) - \(\frac{2}{1}\)) =\(\frac{1}{a}\) - \(\frac{1}{1}\) - \(\frac{1}{a}\) - \(\frac{1}{1}\) - \(\frac{2}{2a}\) - \(\frac{2}{1}\) - \(\frac{2}{2a}\) + \(\frac{2}{1}\)

Remove redundancies. (\(\frac{1}{a}\) - \(\frac{1}{a}\) = 0)

\(\frac{1}{a}\) - \(\frac{1}{1}\) - \(\frac{1}{a}\) - \(\frac{1}{1}\) - \(\frac{2}{2a}\) - \(\frac{2}{1}\) - \(\frac{2}{2a}\) + \(\frac{2}{1}\) = -\(\frac{2}{1}\) -\(\frac{4}{2a}\)

Simplify the fractions.

-\(\frac{2}{1}\) -\(\frac{4}{2a}\)  = -2-\(\frac{2}{a}\)

Answer:

\(l_c=5078.27ft\)

Step-by-step explanation:

From the question we are told that:

Angle of inclination \(\angle=72 \textdegree\)

Height \(h=4500ft\)

Distance b\w cable base and mountain base \(d_{cm}=900ft\)

Generally the equation for length of mountain base \(d_{mb}\) is mathematically given by

 \(Tan\theta=\frac{h}{d_{mb}}\)

 \(d_{mb}=\frac{h}{Tan\theta}\)

 \(d_{mb}=\frac{4500}{Tan 72 \textdegree}\)

 \(d_{mb}=1462.11ft\)

Generally the Pythagoras equation for length of the cable \(l_c\) is mathematically given by

\(l_c^2=h^2+(d_{mb}+d_{cm}^2)\)

\(l_c^2=4500^2+(1462.11}+900}^2)\)

\(l_c=5078.27ft\)

Answer:  \(a_n = 2n+5\)

==================================================

Work Shown:

\(a_n = a_1 + d(n-1)\\\\a_n = 7 + 2(n-1)\\\\a_n = 7 + 2n-2\\\\a_n = 2n+5\\\\\)

--------------------

Explanation:

We plug in \(a_1 = 7 \ \text{ and } \ d = 2\) as they represent the first term and common difference in that order. The common difference is 2 because the number of chairs increases by 2 each time you move up a row.

To verify that answer, let's plug in the value n = 1

\(a_n = 2n+5\\\\a_1 = 2(1)+5\\\\a_1 = 2+5\\\\a_1 = 7\\\\\)

Which matches with the first term being 7. I'll let you verify other terms.

The cross sectional area of the cargo trailer floor, which is a composite figure consisting of a square and an isosceles triangle, indicates that the volume of the inside of the trailer is about 3,952 ft³.

A composite figure is a figure comprising of two or more regular figures.

The possible cross section of the trailer, obtained from a similar question on the internet, includes a composite figure, which includes a rectangle and an isosceles triangle.

Please find attached the cross section of the Cargo Trailer Floor created with MS Word.

The dimensions of the rectangle are; Width = 6 ft, length = 10 ft

The dimensions of the triangle are; Base length 6 ft, leg length = 4 ft

Height of the triangular cross section = √(4² - (6/2)²) = √(7)

The cross sectional area of the trailer, A = 6 × 10 + (1/2) × 6 × √(7)

A = 60 + 3·√7

Volume of the trailer, V = Cross sectional area × Height

V = (60 + 3·√7) × 6.5 = 3900 + 19.5·√7

Volume of the trailer = (3,900 + 19.5·√(7)) ft³ ≈ 3952 ft³

Answer:

4.26

Step-by-step explanation:

If you cut off 2.74 meters off of a 7 meter rope it will leave you with 4.26 meters.

the possible dimensions of the rectangular prism are:

1 unit by 12 units by 10 units

2 units by 6 units by 10 units

3 units by 4 units by 10 units

Let the length and width of the rectangular prism be represented by l and w, respectively. Since the height of the prism is 10 unit cubes, we know that the volume of the prism is:

V = l × w × 10

We are also given that the prism requires 120 unit cubes to fill completely, which means:

V = l × w × 10 = 120

Dividing both sides by 10, we get:

l × w = 12

Now we need to find pairs of positive integers l and w that multiply to 12. These are:

1 × 12

2 × 6

3 × 4

Therefore, the possible dimensions of the rectangular prism are:

1 unit by 12 units by 10 units

2 units by 6 units by 10 units

3 units by 4 units by 10 units

Note that these dimensions are not unique, as we can also obtain different dimensions by exchanging the length and width, or by rotating the prism.

The inequality that represents the number of minutes of calls made in the United States and in France, can be presented as follows:

An inequality expresses the relationship between two or more values that are not equal.

The value of the calling card = $25

The cost of calls made in the United States = $0.10

Cost of calls made in France = $0.25

The number of minutes that can be used for calls in the U.S. = x

The number of minutes that can be used for making calls in France = y

The duration of calls that can be made in the United states is therefore:

\(x_{max} = \dfrac{\$25}{\$0.10} = 250\)

The inequality that represents the number of calls that can be made in the United States is therefore: 0 ≤ x ≤ 250

The duration of calls that can be made in France with the $25 calling card is therefore: \(y_{max}=\dfrac{\$25}{\$0.25} = 100\)

The important to carefully select the correct reagents and conditions in order to successfully synthesize a Grignard reagent.

The synthesis of a Grignard reagent would fail to occur if the incorrect reagent is used. This is because Grignard reagents are highly reactive and require specific conditions in order to successfully form. For example, if the synthesis reaction includes an incorrect solvent, such as water or an alcohol, the Grignard reagent will not form as these solvents are not compatible with the reagent.

Additionally, if the incorrect alkyl halide is used, the Grignard reagent will not form as the reaction requires a specific type of alkyl halide in order to proceed. Therefore, it is important to carefully select the correct reagents and conditions in order to successfully synthesize a Grignard reagent.

To calculate the HDD for the month of January in State College, PA, we need to first determine the base temperature. The base temperature is the temperature below which a building needs to be heated in order to maintain a comfortable indoor temperature. In this case, we will use a base temperature of 65 degrees F.

To calculate the HDD, we need to subtract the average daily temperature from the base temperature and sum up the values for each day of the month. If we assume that January has 31 days, we can calculate the HDD as follows:

HDD = (65 - 35) x 31
HDD = 930

So the HDD for the month of January in State College, PA is 930. This means that during the month of January, there were 930 heating degree days, which indicates the amount of heating required to maintain a comfortable indoor temperature. It is important to note that the HDD can vary depending on the base temperature used, so it is important to choose a base temperature that is appropriate for the climate and the building being heated.

The type of nonprobability design that is most likely to yield a representative sample is a stratified random sampling.

In stratified random sampling, the population is divided into distinct subgroups or strata based on certain characteristics or variables that are relevant to the research objective. Then, a random sample is selected from each stratum proportionally to the size or importance of that stratum in the population. This approach ensures that the sample reflects the diversity and heterogeneity of the population.

By stratifying the population and using random sampling within each stratum, the stratified random sampling design increases the likelihood of obtaining a representative sample. It allows for accurate representation of different groups within the population, which can help reduce sampling bias and provide more precise estimates of population characteristics.

However, it's important to note that even with stratified random sampling, there may still be limitations and potential sources of bias. Factors such as nonresponse rates and the accuracy of the population data used for stratification can impact the representativeness of the sample. Nevertheless, when properly implemented, stratified random sampling is a valuable nonprobability design for achieving representativeness in a sample.

The output you have provided appears to be a regression analysis of some data, where a dependent variable is regressed on one independent variable.

Here's how to interpret the output:

The model's equation is:

Dependent Variable = Intercept + (Coefficient * Independent Variable)

In this case, the dependent variable is not mentioned, but we know it has 24 observations. The independent variable is advertising.

The coefficients table provides information about the intercept and coefficient of the independent variable. The intercept is 39.4, which means that when the advertising budget is zero, the dependent variable (whatever it is) is expected to have a value of 39.4.

The coefficient of the independent variable is 2.89, which means that for each one-unit increase in advertising, the dependent variable is expected to increase by 2.89 units.

The standard error of the intercept is 14.14, which is a measure of the uncertainty in the estimate of the intercept. The t-statistic is 2.786, which is calculated by dividing the intercept estimate by its standard error. The p-value associated with the intercept is 0.0045, which means that if the null hypothesis (that the intercept is zero) were true, the probability of obtaining an estimate as extreme as 39.4 or more extreme in the direction of the alternative hypothesis would be only 0.0045. Since this is less than the conventional alpha level of 0.05, we can reject the null hypothesis and conclude that the intercept is significantly different from zero.

Similarly, the standard error of the coefficient of the independent variable is 1.69, which is a measure of the uncertainty in the estimate of the coefficient. The t-statistic is -1.71, which is calculated by dividing the coefficient estimate by its standard error.

The p-value associated with the coefficient is 0.059, which means that if the null hypothesis (that the coefficient is zero) were true, the probability of obtaining an estimate as extreme as 2.89 or more extreme in the direction of the alternative hypothesis would be 0.059. Since this is greater than the conventional alpha level of 0.05, we cannot reject the null hypothesis and conclude that the coefficient is not significantly different from zero at the 5% level of significance.

However, it is worth noting that the p-value is close to the significance level, so the result is borderline significant.

Answer:

Only sometimes true

Step-by-step explanation:

Now, I'm going to go out on a whim here, since your equation writing isn't the best, but I will assume that the equation is:

x = x/3 * 3x

Now, to simplify this equation, we will multiply both sides by 3, giving us:

3x = x * 3x

Then, simplify the left side:

3x = \(3x^{2}\)

Divide by 3 gives us:

\(x = x^{2}\)

Now, this is only true in two cases. When x is 1, and when x is 0. So, that equation is only sometimes true.
