The maximum value of the objective function Z is 1800. The optimal values for the decision variables are X1 = 10, X2 = 0, and X3 = 0. The constraints are satisfied, and the optimal solution has been reached using the Simplex Method.

To compute the given problem using the Simplex Method, we need to convert it into a standard form.

The standard form of a linear programming problem consists of maximizing or minimizing a linear objective function subject to linear inequality constraints and non-negativity constraints.

Let's rewrite the problem in standard form:

Maximize:

Z = 50X1 + 20X2 + 10X3

Subject to the constraints:

2X1 + 4X2 + 5X3 <= 200

X1 + X3 <= 90

X1 + 2X2 <= 30

X1, X2, X3 >= 0

To convert the problem into standard form, we introduce slack variables (S1, S2, S3) for each constraint and rewrite the constraints as equalities:

2X1 + 4X2 + 5X3 + S1 = 200

X1 + X3 + S2 = 90

X1 + 2X2 + S3 = 30

Now, we have the following equations:

Objective function:

Z = 50X1 + 20X2 + 10X3 + 0S1 + 0S2 + 0S3

Constraints:

2X1 + 4X2 + 5X3 + S1 = 200

X1 + X3 + S2 = 90

X1 + 2X2 + S3 = 30

X1, X2, X3, S1, S2, S3 >= 0

Next, we will create a table representing the initial simplex tableau:

  | X1 | X2 | X3 | S1 | S2 | S3 | RHS |

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

Z  | 50 | 20 | 10 | 0  | 0  | 0  | 0   |

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

S1 | 2  | 4  | 5  | 1  | 0  | 0  | 200 |

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

S2 | 1  | 0  | 1  | 0  | 1  | 0  | 90  |

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

S3 | 1  | 2  | 0  | 0  | 0  | 1  | 30  |

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

To compute the optimal solution using the Simplex Method, we'll perform iterations by applying the simplex pivot operations until we reach an optimal solution.

Iterating through the simplex method steps, we can find the following tableau:

  | X1 | X2 | X3 | S1 | S2 | S3 | RHS |

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

Z  | 0  | 40 | 10 | 0  | 0  | -500| 1800|

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

S1 | 0  | 3  | 5  | 1  | 0  | -40 | 120  |

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

S2 | 1  | 0  | 1  | 0  | 1  | 0   | 90   |

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

X1 | 0  | 2  | 0  | 0  | 0  | -1  | 10   |

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

The optimal solution is Z = 1800, X1 = 10, X2 = 0, X3 = 0, S1 = 120, S2 = 90, S3 = 0.

Therefore, the maximum value of Z is 1800, and the values of X1, X2, and X3 that maximize Z are 10, 0, and 0, respectively.

We have that, given the curve x = e5y, 0 ≤ y ≤ 2, it rotates around the y axis, we are going to obtain the following integrals

Part A: State, but do not evaluate, an integral for the surface area resulted by integrating with respect to x. Integrating with respect to x, the formula for finding the surface area of a curve rotated about the y axis is:

\(S=2\pi \int abxf(y)\sqrt{[1+({f(x))^2}']}dx\)

Since the curve revolves around the y-axis, the equation will have the form x = f(y). Therefore, x = e5yTaking the derivative of the equation, we have:

\({f(y)}' = 5e5y\)

multiplying by

\(f(y)2\pi \intabxf(y)\sqrt{[1+(f′(x))^2]}dx=2\pi \int 02e^5y(2\pi(5e5y)\sqrt{[1+(5e^5y)^2]}dx\)

Integrating and substituting the limits are obtained;

\(2\pi \int 02e^5y( 2\pi(5e^5y)\sqrt{[1+(5e5y)^2}]dx = 2 \pi \int 02e^5y \sqrt{(1+ 25e10y)}dy\)

Part B: Establish, but do not evaluate, an integral for the surface area resulted by integrating with respect to y. Integrating with respect to y, the formula for finding the surface area of a curve rotated about the y-axis is:

\(S=2\pi \int abxf(y)\sqrt{[1+(f′(x))^2}] dx\)

Since the equation is given as \(x = e^5y\), we will convert it to \(y = f(x)\) by taking the natural logarithm of both sides.

\(ln x = ln(e)^5y5 = 5y\)

So, the formula is \(y = 1/5 ln(x)\) using this formula as f(x) in the surface area formula;

\(S = 2\pi \int ab1/ 5ln(x) \sqrt{[1+((1 /5x)\\2}]dx.\)

Answer:

Therefore, the elevation of the car on the stretch of road, rounded to the nearest tenth, is approximately 29.7 meters.

Step-by-step explanation:

To find the elevation of the car on a stretch of road that extends horizontally 125 meters, we can use trigonometry.

Given:

Angle of the road = 13°

Horizontal distance = 125 meters

We can use the tangent function to calculate the elevation:

tan(angle) = opposite / adjacent

In this case, the opposite side represents the elevation, and the adjacent side represents the horizontal distance.

Let's denote the elevation as "e". The equation becomes:

tan(13°) = e / 125

To solve for "e", we can rearrange the equation:

e = 125 * tan(13°)

Using a calculator, we can evaluate this expression:

e ≈ 125 * tan(13°) ≈ 29.7

Step-by-step explanation:

the area of the shaded portion is calculated as

area of sector - area of white Δ

area of sector = area of circle × fraction of circle

                        = πr² × \(\frac{90}{360}\) ( r is the radius )

                        = π × 8² × \(\frac{1}{4}\)

B. In the alternate universe, the d subshell would have 10 orbitals.

In the alternate universe where the possible values of mℓ range from -l-1 to l+1, the number of orbitals in each subshell can be determined.

A. For the p subshell, the value of l is 1. Therefore, the range of mℓ would be -1, 0, and 1. Including the additional values of -2 and 2 from the alternate universe, the total number of orbitals in the p subshell would be 5 (mℓ = -2, -1, 0, 1, 2).

B. For the d subshell, the value of l is 2. In the conventional universe, the range of mℓ would be -2, -1, 0, 1, and 2, resulting in 5 orbitals. However, in the alternate universe, the range would extend to -3 and 3. Including these additional values, the total number of orbitals in the d subshell would be 10 (mℓ = -3, -2, -1, 0, 1, 2, 3).

The required total amount paid for magazine and pencil is 108p.

Simplification generally means finding an answer for the complex calculation that may involve numbers on division, multiplication, square roots, cube  roots, plus and minus.

Now it is given that,

Costing of a magazine = 83p

Costing of pencil = 45p

Thus, Total costing = Costing of a magazine + Costing of pencil

Putting the values we get,

Total costing = 83p + 45p = 128p

Now voucher gives 20p off

So, Final Costing = Total costing - Voucher off

⇒ Final Costing = 28p - 20p

⇒ Final Costing = 108p

this is the equired total amount paid for magazine and pencil.

Thus, the required total amount paid for magazine and pencil is 108p.

To find the probability that a randomly selected film is between 100 and 120 minutes long, we can use the properties of the normal distribution.

First, we calculate the z-scores for the lower and upper bounds of the desired range:

Lower z-score = (100 - 96) / 12 = 0.333

Upper z-score = (120 - 96) / 12 = 2.000

Next, we look up the probabilities associated with these z-scores in the standard normal distribution table. The probability for the lower bound is P(Z < 0.333) and the probability for the upper bound is P(Z < 2.000).

Using the table or a statistical calculator, we find that the probability for the lower bound is approximately 0.6293 and the probability for the upper bound is approximately 0.9772. To find the probability within the desired range, we subtract the lower probability from the upper probability:

P(100 < X < 120) = P(Z < 2.000) - P(Z < 0.333) = 0.9772 - 0.6293 = 0.3479

Therefore, the probability that a randomly selected film is between 100 and 120 minutes long is approximately 0.3479, or 34.79%.

The value of the triple integral ∭E 7x dV, where E is bounded by the paraboloid x = 7y^2 + 7z^2 and the plane x = 7, is 0.

To evaluate this triple integral, we need to determine the limits of integration for each variable. Let's express the paraboloid equation in terms of y and z:

x = 7y^2 + 7z^2

Since the paraboloid is bounded by the plane x = 7, we can set up the following limits:

0 ≤ x ≤ 7
0 ≤ y
0 ≤ z

Now we can rewrite the integral as:

∭E 7x dV = ∫[0 to 7] ∫[0 to ∞] ∫[0 to ∞] 7x dy dz dx

To evaluate this integral, we integrate with respect to y first:

∫[0 to 7] ∫[0 to ∞] 7x dy dz = 7 ∫[0 to 7] xy |[0 to ∞] dz

Simplifying further, we have:

7 ∫[0 to 7] ∞ dz = ∞

The forward Fourier Transform formula for a signal is X(jω) = F{x(t)}. The inverse Fourier Transform formula is x(t) = F^(-1){X(jω)}. The two formulas are related by the Fourier Transform property called duality or symmetry.

1. The forward Fourier Transform formula is given by:

  X(jω) = ∫[x(t) * e^(-jωt)] dt

  This formula calculates the complex spectrum X(jω) of a signal x(t) by integrating the product of the signal and a complex exponential function.

2. The inverse Fourier Transform formula is given by:

  x(t) = (1/2π) ∫[X(jω) * e^(jωt)] dω

  This formula reconstructs the original signal x(t) from its complex spectrum X(jω) by integrating the product of the spectrum and a complex exponential function.

  The similarity between these two formulas is known as the Fourier Transform property of duality or symmetry. It states that the Fourier Transform pair (X(jω), x(t)) has a symmetric relationship in the frequency and time domains. The forward transform calculates the spectrum, while the inverse transform recovers the original signal. The duality property indicates that if the spectrum is known, the inverse transform can reconstruct the original signal, and vice versa.

3. To determine the Fourier Transform of the given signal x(t) = [-1, 1, 0, -1], we apply the defining integral:

  X(jω) = ∫[-1 * e^(-jωt1) + 1 * e^(-jωt2) + 0 * e^(-jωt3) - 1 * e^(-jωt4)] dt

  Here, t1, t2, t3, t4 represent the respective time instants for each element of the signal.

  Substituting the time values and performing the integration, we can obtain the Fourier Transform of x(t).

Note: Please note that without specific values for t1, t2, t3, and t4, we cannot provide the numerical result of the Fourier Transform for the given signal. The final answer will depend on these time instants.

Triangle WXY is an Isosceles right triangle, since WX=XY.

First, we determine the length of WY using Pythagoras Theorem.

\(WY=\sqrt{4^2+4^2}\\WY=\sqrt{32}\)

Since triangle WXY is Isosceles, \(\angle XYW=45^\circ\)

\(\angle XYZ=\angle XYW+\angle WYZ\\135^\circ=45^\circ+\angle WYZ\\\angle WYZ=135^\circ-45^\circ=90^\circ\)

Therefore:

Triangle WYZ is a right triangle with WZ as the hypothenuse.

Applying Pythagoras Theorem

\(WZ^2=WY^2+YZ^2\\9^2=(\sqrt{32})^2+a^2\\a^2=81-32\\a^2=49\\a^2=7^2\\$Therefore: a=7\)

The value of a in the triangle illustrated is 7.

From the information, the length of WY will be:

WY = ✓4² + ✓4²

WY = ✓32

Therefore, angle WYZ will be:

= 135° - 45°

= 90°

Therefore, the value of a will be calculated thus:

a² = 9² - (✓32)²

a² = 81- 32

a = ✓49

a = 7

Answer:

The coordinate of \(Z\) is 13.36.

Step-by-step explanation:

According to the statement, we have the following information:

\(\frac{XY}{XZ} = \frac{5}{12}\) (1)

\(\frac{YZ}{XZ} = \frac{7}{12}\) (2)

\(X = 0.4\) (3)

\(Y = 5.8\) (4)

From (2), we have the following expression:

\(YZ = \frac{7}{12}\cdot XZ\)

\(Y-Z =\frac{7}{12}\cdot (X-Z)\)

\(Y - Z = \frac{7}{12}\cdot X -\frac{7}{12}\cdot Z\)

\(Y-\frac{7}{12}\cdot X = Z-\frac{7}{12}\cdot Z\)

\(\frac{5}{12}\cdot Z = Y-\frac{7}{12}\cdot X\)

\(5\cdot Z = 12\cdot Y-7\cdot X\)

\(Z = \frac{12}{5}\cdot Y-\frac{7}{5}\cdot X\) (5)

If we know that \(Y = 5.8\) and \(X = 0.4\), then the coordinate of \(Z\) is:

\(Z = \frac{12}{5}\cdot (5.8)-\frac{7}{5}\cdot (0.4)\)

\(Z = 13.36\)

The coordinate of \(Z\) is 13.36.
