x > 6 , x∈ R⁺  respectively.

Function f(x) is equal to e^x

Function g(x) = x + 6

Composite function  (gof)(x) is equal to:

(gof)(x)

= g ( f(x))

= g ( e^x )

= e^x + 6

Domain represents all input values and range represents all output values.

Domain of the composite function (gof)(x) is equal to x∈ R⁺  (real numbers)

Range of the composite function (gof)(x)  is equal to  x > 6 , x∈ R⁺

Therefore, the domain and range of the composite function (gof)(x)  is equal to x∈ R⁺  ( real numbers ) and  x > 6 , x∈ R⁺  respectively.

Answer:

The length of side x in a 30-60-90 triangle is 2√3.

Step-by-step explanation:

The numbers 30-60-90 are angles, so we need to find the side x of a right triangle with the following information:

θ: is one angle of the right triangle = 30°

α: is the other angle of the right triangle = 60°

a: is one side of the right triangle = √3

b: is the other side of the right triangle =?

x: is the hypotenuse of the right triangle =?

The length of the hypotenuse can be found by Pitagoras:

\( x^{2} = a^{2} + b^{2} \)    (1)

So, we need to find the side "b". We can calculate it with the given angles.

From the side "a" we have:

\( cos(\alpha) = \frac{a}{x} \)

\( cos(60) = \frac{\sqrt{3}}{x} \)    (2)

From the side "b":

\( sin(\alpha) = \frac{b}{x} \)

\( sin(60) = \frac{b}{x} \)   (3)

Now, we can calculate "b" by dividing equation (3) by equation (2).

\( tan(60) = \frac{\frac{b}{x}}{\frac{\sqrt{3}}{x}} \)

\( b = tan(60)*\sqrt{3} = 3 \)

Finally, we can find the length of the hypotenuse with equation (1):

\( x = \sqrt{a^{2} + b^{2}} = \sqrt{(\sqrt{3})^{2} + (3)^{2}} = 2\sqrt{3} \)

Therefore, the length of side x in a 30-60-90 triangle is 2√3.

The statement "dispersion models are selected based on the phase of the material being modeled in a release scenario" is true as Different dispersion models are needed for different phases (gas, liquid, solid) due to differences in behavior and transport mechanisms.

Dispersion models are used to predict the spread of pollutants, and they depend on the physical and chemical properties of the material being released.

Generally, different models are used for each phase of the material, such as the Gaussian plume model for gases, the plume rise model for heated gases, and the particle dispersion model for particles.

Each of these models is based on different characteristics and equations which allow for the most accurate prediction of the dispersion of pollutants.

For example, the Gaussian plume model considers the wind velocity, turbulence, and buoyancy of the released material, whereas the plume rise model considers the momentum, thermal expansion, and buoyancy of the released material.

Therefore, dispersion models are selected based on the phase of the material being modeled in a release scenario.

The given system of differential equations is:

x'(t) = -95x + 53y - 2xy

y'(t) = -185x - 203y - xy

To solve this system, we can use various methods such as substitution or matrix methods. Let's solve it using the matrix method.

We can rewrite the system of differential equations in matrix form as:

X' = AX

where X = [x y]', X' = [x'(t) y'(t)]', and A is the coefficient matrix:

A = [[-95 53], [-185 -203]]

To find the solutions, we need to find the eigenvalues and eigenvectors of matrix A. The eigenvalues are the roots of the characteristic equation det(A - λI) = 0, where I is the identity matrix. Solving this equation gives us the eigenvalues λ1 = -100 and λ2 = -198.

Next, we find the eigenvectors associated with each eigenvalue. For λ1 = -100, the corresponding eigenvector is [2 1]'. For λ2 = -198, the corresponding eigenvector is [-1 1]'.

Therefore, the general solution of the system of differential equations is:

X(t) = c1e^(-100t)[2 1]' + c2e^(-198t)[-1 1]'

where c1 and c2 are constants determined by initial conditions.

In summary, the solution to the system of differential equations is given by X(t) = c1e^(-100t)[2 1]' + c2e^(-198t)[-1 1]', where c1 and c2 are constants determined by the initial conditions.

Answer: (-13, -3), (-1, 0), and (7, 2).

Step-by-step explanation:

First, we have a function f(x) and we know that 3 points (x, y) of this function are:

(-3, -13), (0, -1), and (2, 7).

Now, if we have a function g(x) and we know that g(x) is the inverse of f(x), we have that:

g(f(x)) = x.

this means that if f(x) = y then g(y) = x.

then if (-3, -13) is a point in the f(x) graph, (-13, -3) must be a point in the g(x) graph.

Then 3 points in on the inverse of the function f(x) are:

(-13, -3), (-1, 0), and (7, 2).

Therefore, the equation of the line passing through (-3, -5) and parallel to the line 2x + 3y = 15, in slope-intercept form, is y = (-2/3)x - 7.

To find the equation of a line parallel to the line 2x + 3y = 15 and passing through the point (-3, -5), we need to determine the slope of the given line and use it to construct the equation in slope-intercept form (y = mx + b).

The given line is in the form Ax + By = C, where A = 2, B = 3, and C = 15. To find the slope of this line, we can rearrange the equation to isolate y:

2x + 3y = 15

3y = -2x + 15

y = (-2/3)x + 5

The slope of the given line is -2/3.

Since the line we want to find is parallel to this line, it will have the same slope. Therefore, the slope of the line passing through (-3, -5) will also be -2/3.

Now, we can use the point-slope form of a linear equation to write the equation of the line:

y - y1 = m(x - x1)

Substituting the values of (-3, -5) and -2/3 for (x1, y1) and m, respectively:

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

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

To convert this equation into slope-intercept form, we can simplify and rearrange:

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

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

y = (-2/3)x - 7

(a) Expected NPV = £592,592.59, (b) Expected Value of Abandonment Option = £9,259,259.26, (c) Expected Value of Expansion Option = £251,136.36, (d) Maximum Fee = £4,166,666.67, (e) A real option to abandon a project can be analogous to an American put option in finance.

(a) The expected net present value (NPV) of the project can be calculated by finding the present value of each cash flow and then taking the weighted average based on the probabilities.

The present value of the yearly cash flows from rental income can be calculated using the formula: PV = CF / (1 + r)^n, where CF is the cash flow, r is the discount rate, and n is the number of years.

For the case where the new road is built:

PV = £1,100,000 / (1 + 0.08)^1 = £1,018,518.52

For the case where the new road is not built:

PV = £180,000 / (1 + 0.08)^1 = £166,666.67

The expected NPV is then calculated as the weighted average:

Expected NPV = (0.5 * £1,018,518.52) + (0.5 * £166,666.67) = £592,592.59

(b) The expected value now of the abandonment option can be calculated as the present value of the potential selling price of £10 million:

Expected Value of Abandonment Option = £10,000,000 / (1 + 0.08)^1 = £9,259,259.26

Since the expected value of the abandonment option (£9,259,259.26) is greater than the expected NPV of the project (£592,592.59), it indicates that the abandonment option is worthwhile.

(c) The expected value now of the expansion option can be calculated similarly to the previous calculations. We need to calculate the present value of the two potential cash flows from the expansion and take the weighted average based on the probabilities.

For the case where a large department store chooses to occupy the new space:

PV = £354,000 / (1 + 0.08)^2 = £295,454.55

For the case where a large department store does not choose to occupy the new space:

PV = £168,000 / (1 + 0.08)^2 = £140,000.00

Expected Value of Expansion Option = (0.75 * £295,454.55) + (0.25 * £140,000.00) = £251,136.36

(d) To determine the maximum fee Dash would pay now to own the land without further investment for one year, we need to calculate the present value of the potential selling price of £4.5 million in one year.

Maximum Fee = £4,500,000 / (1 + 0.08)^1 = £4,166,666.67

(e) A real option to abandon a project can be analogous to an American put option in finance. The option gives the holder the right, but not the obligation, to sell or abandon the project. The specific components of the option analogy include the underlying asset (the project), the exercise price (the cost of abandonment or selling), the expiration date (the time limit to exercise the option), and the value of the option (the expected value of abandoning or selling the project). The analogy allows decision-makers to assess the value of flexibility and adapt their choices based on changing circumstances, similar to how put options provide flexibility to sell assets in the financial market.

A majority of the college seniors in the survey are not planning to attend graduate school. The discipline of business constitutes the majority of individuals in the survey.

In more detail, let's analyze the crosstabulation table. To determine if a majority of the seniors are planning to attend graduate school, we can compare the total number of "yes" responses (140) to the total number of respondents (400).

Since 140 is less than 50% of 400, we can conclude that a majority of the seniors are not planning to attend graduate school.

To identify which discipline constitutes the majority of individuals in the survey, we can examine the column totals.

The highest column total corresponds to the "engineering" discipline, with 146 individuals. Therefore, engineering is the discipline that constitutes the majority of individuals in the survey.

To compute the row percentages, we divide each cell by its respective row total and multiply by 100. This gives us the percentage of students in each undergraduate major who plan to attend graduate school.

By analyzing these percentages, we can identify any patterns or relationships between the students' majors and their intention of attending graduate school.

The remainder of the polynomial using the remainder theorem and factor theorem is 6.

Apply the remainder theorem,

When we divide a polynomial

f(x) by (x − c)

f(x) = (x − c)q(x) + r

f(c) = 0 + r

Here,

f(x)=(x−c)q(x)+rf(c)=0+r

and (x−c) is (x−(−2))

Therefore,

f(−2) = \((-2)^{4} - (-2)^3 - 3(-2)^2 + 4(-2) + 2\)

= 16 + 8 − 12 − 8 + 2

= 6

Hence, the remainder of the polynomial using the remainder theorem is 6.

Whereas using the factor theorem and doing synthetic division, we get,  

x = -2 is a zero of f(x), and x+2 is a factor of f(x). To factor f(x), we divide

the coefficients of the polynomial as follows -

         -2   |   1  -1    -3     4      2

                      -2   6    -6      4

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

                    1   -3   3    -2     6

Hence, we get that 6 is the remainder when (\(x^4-x^3-3x^2+4x+2\)) ÷ (x+2), using the factor theorem.

Answer: $63.40

Step-by-step explanation:

She starts out with $317  but she will only get 80%  which means she will lose 20%

100%-80%=20%

take 20% of 317

.2 x 317    convert 20% to decimal by moving decimal twice and multiply

=63.4

She will lose $63.40

Reason:

If she withdraws early, she can only withdraw 80% of what she put in. She takes a 20% penalty.

20% of 317 = 0.20*317 = 63.40 dollars is how much she loses.

Put another way:

She is able to withdraw 0.80*317 = 253.60 dollars if doing so early. She lost 317-253.60 = 63.40 dollars

The mean absolute deviation for the group of household incomes is approximately 14.8 (rounded to the nearest tenth).

To calculate the mean absolute deviation (MAD) for a group of data, we follow these steps:

Find the mean (average) of the data set.

Subtract the mean from each data point, obtaining the deviations.

Take the absolute value of each deviation.

Find the mean of the absolute deviations.

Given the household incomes for 10 different households:

38, 45, 76, 93, 50, 54, 29, 44, 62, 31

Let's calculate the MAD step by step:

Find the mean (average):

Mean = (38 + 45 + 76 + 93 + 50 + 54 + 29 + 44 + 62 + 31) / 10

Mean = 482 / 10

Mean = 48.2

Calculate the deviations:

Deviation for each data point = Data point - Mean

Deviation for 38 = 38 - 48.2 = -10.2

Deviation for 45 = 45 - 48.2 = -3.2

Deviation for 76 = 76 - 48.2 = 27.8

Deviation for 93 = 93 - 48.2 = 44.8

Deviation for 50 = 50 - 48.2 = 1.8

Deviation for 54 = 54 - 48.2 = 5.8

Deviation for 29 = 29 - 48.2 = -19.2

Deviation for 44 = 44 - 48.2 = -4.2

Deviation for 62 = 62 - 48.2 = 13.8

Deviation for 31 = 31 - 48.2 = -17.2

Take the absolute value of each deviation:

Absolute deviation for each data point = |Deviation|

Absolute deviation for -10.2 = 10.2

Absolute deviation for -3.2 = 3.2

Absolute deviation for 27.8 = 27.8

Absolute deviation for 44.8 = 44.8

Absolute deviation for 1.8 = 1.8

Absolute deviation for 5.8 = 5.8

Absolute deviation for -19.2 = 19.2

Absolute deviation for -4.2 = 4.2

Absolute deviation for 13.8 = 13.8

Absolute deviation for -17.2 = 17.2

Find the mean of the absolute deviations:

Mean Absolute Deviation (MAD) = (10.2 + 3.2 + 27.8 + 44.8 + 1.8 + 5.8 + 19.2 + 4.2 + 13.8 + 17.2) / 10

MAD = 148 / 10

MAD = 14.8

To the nearest tenth, this means that the mean absolute deviation for the group of household incomes is around 14.8.

The probability that he grabbed exactly 3 bronze caps and exactly 1 silver caps is 0.1247.

In this problem, we need to find the probability of Olav randomly grabbing 6 caps and getting exactly 3 bronze caps and exactly 1 silver cap.

To solve this problem, we can use the concept of combinations. The number of ways to choose 3 bronze caps out of 6 is given by the combination \(^6C_{3}\), and the number of ways to choose 1 silver cap out of 5 is given by the combination \(^5C_{1}\).

The number of ways to choose the remaining 2 caps (which must be gold) out of 5 is given by the combination \(^5C_{2}\).

Therefore, the total number of ways that Olav can grab 6 caps with exactly 3 bronze and 1 silver is given by:

\(^6C_{3}\)* \(^5C_{1}\) * \(^5C_{2}\) = 20 * 5 * 10 = 1000

The total number of ways to choose 6 caps out of 16 is given by

\(^{16}C_{6}\\\), which is:

\(^{16}C_{6}\\\)= 8008

Therefore, the probability that Olav grabbed exactly 3 bronze caps and exactly 1 silver cap is:

P = 1000 / 8008 = 0.1247 (rounded to 4 decimal places)

Hence, the probability that Olav grabbed exactly 3 bronze caps and exactly 1 silver cap is 0.1247.
