(a) Construct the dual problem for this primal problem.
(b) Solve the dual problem graphically. Use this solution to identify the shadow prices for the resources in the primal problem.
(b) By solving the dual problem graphically, we find that the optimal solution occurs at the vertex (0, 2) with a minimum value of W = 10. The shadow price for resource 1 (x1 + x3 ≤ 3) in the primal problem is 10. This means that an additional unit of resource 1 would increase the objective function value by 10. The shadow price for resource 2 (x2 + 2x3 ≤ 5) in the primal problem is 0. This indicates that the optimal solution is not sensitive to changes in resource 2.
(a) To construct the dual problem, we will assign dual variables y1 and y2 to the constraints of the primal problem and convert the objective function to the dual form. The dual problem has two constraints corresponding to the resources in the primal problem. The objective function in the dual problem represents the costs or prices associated with the resources.
(b) To solve the dual problem graphically, we will plot the feasible region and find the optimal solution.
Constraint 1: y1 + y2 ≥ 2
Rearranging the inequality, we get:
y2 ≥ 2 - y1
Constraint 2: y1 + 2y2 ≥ 6
Rearranging the inequality, we get:
y2 ≥ (6 - y1) / 2
The feasible region is the intersection of the two constraint inequalities, taking into account the non-negativity constraints y1 ≥ 0 and y2 ≥ 0.
Now, let's plot the feasible region on a graph:
Starting with the y-axis, plot points (0, 2) and (0, 3) to represent the non-negativity constraint y2 ≥ 0.
Next, draw a line with a slope of -1 passing through the point (0, 2).
Draw another line with a slope of -0.5 passing through the point (0, 3).
The feasible region is the area bounded by these two lines and the y-axis.
To find the optimal solution, we need to evaluate the objective function at the vertices of the feasible region.
Vertices of the feasible region:
(0, 2)
(0, 3)
Now, substitute these vertices into the objective function:
For (0, 2):
W = 3(0) + 5(2) = 10
For (0, 3):
W = 3(0) + 5(3) = 15

A flange is to be machined at a diameter of 6.77 cm ± 0.01 cm. The process standard deviation is 0.005 cm. What is the process capability ratio? A. 0.67. B. 1.01. C. 0.87. D. 0,34.
The process capability ratio is approximately 0.67 (option A).
To calculate the process capability ratio, we need to use the following formula:
Process Capability Ratio = (Upper Specification Limit - Lower Specification Limit) / (6 * Process Standard Deviation)
Given the following values:
Upper Specification Limit = Diameter + Tolerance = 6.77 cm + 0.01 cm = 6.78 cm
Lower Specification Limit = Diameter - Tolerance = 6.77 cm - 0.01 cm = 6.76 cm
Process Standard Deviation = 0.005 cm
Plugging these values into the formula, we have:
Process Capability Ratio = (6.78 cm - 6.76 cm) / (6 * 0.005 cm)
Process Capability Ratio = 0.02 cm / 0.03 cm
Process Capability Ratio ≈ 0.67
Therefore, the process capability ratio is approximately 0.67. The correct answer is A) 0.67.

Find the volume of the largest rectangular box with edges parallel to the axes that can be inscribed in the ellipsoid
(x^2/4) + (y^2/64) + (z^2/49) = 1
Hint: By symmetry, you can restrict your attention to the first octant (where x,y,z=0), and assume your volume has the form V=8xyz. Then arguing by symmetry, you need only look for points which achieve the maximum which lie in the first octant.
What is the maximum volume?
The maximum volume of the largest rectangular box that can be inscribed in the ellipsoid can be calculated by finding the x, y, and z coordinates in the first octant that satisfy the equation (x^2/4) + (y^2/64) + (z^2/49) = 1.
Since the box must have edges parallel to the axes, the coordinates will also be the lengths of the box's edges. From the equation, we get the x coordinate to be 2, the y coordinate to be 8, and the z coordinate to be 7.
The volume of the box is the product of its edges, so the maximum volume of the box is V = 8xyz = 8 * 2 * 8 * 7 = 896.

A vegetable has 100 tomato plants arranged in a 10-by-10 array
The total Number of tomato plants in the array is 100.
In a 10-by-10 array of tomato plants, there are 100 tomato plants arranged. Here, we have to determine the numbers of plants in each row and column, as well as the total number of plants.
In an array, we have rows and columns. If we have a total of 100 tomato plants, we have to divide the number of plants by the number of rows or columns, since the rows and columns are equal.
So, for 10 rows, each row contains 100/10 = 10 plants, and for 10 columns, each column contains 100/10 = 10 plants. In this example, each row and column contains the same number of plants, and the array is a square array.
Since there are ten rows and ten columns, each containing ten plants, the total number of plants is 10 x 10 = 100 plants.
In conclusion, a 10-by-10 array of tomato plants contains 100 tomato plants arranged.
Each row and column contain ten plants, and the array is square.

A nut mixture of almonds and cashew nuts at a small fair is $1.00 per pound of almonds and $3.55 per pound of cashew nuts. Over the entire day, 65 pounds of the nut mixture were sold for $189.95. If p is the number almonds and n is the number of cashew nuts, then the system of equations that models this scenario is: p+n=65 p+3.55n=189.95 Determine the correct description and amount of pounds for almonds and cashew nuts that were sold
Answer:
p is 16 and N is 49.
Step-by-step explanation:
Answer:
p = 16
n = 49
Step-by-step explanation:
p + n = 65
p + 3.55n = 189.95
To solve this system of equations, you have to use substitution. This means that you have to set one equation equal to one of the variables. You then have to substitute that variable into the second equation.
Rearrange the first equation so that it equals p.
p + n = 65
p = 65 - n
Substitute the p-value into the second equation.
p + 3.55n = 189.95
(65 - n) + 3.55n = 189.95
Solve for n.
65 - n + 3.55n = 189.95
65 + 2.55n = 189.95
(65 + 2.55n) - 65 = 189.95 - 65
2.55n = 124.95
(2.55n)/2.55 = 124.95/2.55
n = 49
Use this n-value to solve for p. You can pick whichever equation you want to solve for p and get the same answer. I will use the first answer.
p + n = 65
p + 49 = 65
(p + 49) - 49 = 65 - 49
p = 16
There are 16 pounds of almonds and 49 pounds of cashews.

A figure of a quadrilateral.
To find:
The measures of angle 1 and angle 2.
Solution:
The given figure has two pairs of congruent adjacent sides. So, the quadrilateral in the figure is a kite.
We know that the diagonals of a kit are perpendicular to each other at the point of intersection.
\(m\angle 1=90^\circ\)
According to the angle sum property, the sum of all interior angles of a triangle is 180 degrees.
\(90^\circ+65^\circ+m\angle 2=180^\circ\)

a rectangle with sides of length n+2 and n is compared to a square with sides of length n+1 are the two shapes equal in perimeter?
Answer:
yes
Step-by-step explanation:
Both of the figures have the same perimeter (4n + 4) hence equal in perimeter,
What are the area and perimeter of a rectangle?We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.
We know the perimeter of a rectangle is 2(length + width) and the perimeter of a square is 4×side.
Given, A rectangle with sides of length n+2 and n.
∴ Perimeter = 2((n + 2) + n)
= 2(2n + 2).
= 4n + 4.
Also given, A square with sides of length n + 1.
∴ Perimeter = 4(n + 1).
= 4n + 4.

I NEED AN EXPLANATION!! pls
If Mr. Jamison bought 8 dozen sketch pencils, 6dozen colored pencils and 3 dozen art gum, with a sales tax of 8 percent, considering each dozen of sketch pencils costed $x, colored pencils costed $y and art gums costed $z, the total bill approximately would be
$[(8x + 6y + 3z) + 0.08(8x + 6y + 3z)].
As per the question statement, Mr. Jamison bought 8 dozen sketch pencils, 6dozen colored pencils and 3 dozen art gum, with a sales tax of 8 Percent, and since no information is provided about the price of the sketch pencils, colored pencils or art gums, let us consider that each dozen of sketch pencils costed $x, colored pencils costed $y and art gums costed $z.
We are required to calculate the total approximate bill, Mr. Jamison would have to pay for the items he picked up.
To solve this question, first we will have to calculate the total price of the items he picked, without any taxes, i.e.,
$[(8 * x) + (6 * y) + (3 * z)] = $(8x + 6y + 3z).
Now an 8% sales tax on the price of the items bought will be
8% of $[(8x + 6y + 3z), i.e.,
[(8/100) * (8x + 6y + 3z)]
= $[0.08(8x + 6y + 3z)]
Therefore, total bill = (Total item costs + tax)
= $(8x + 6y + 3z) + $[0.08(8x + 6y + 3z)]
= $[(8x + 6y + 3z) + 0.08(8x + 6y + 3z)]

Prove the theorem: Let T be a translation along l. If l' is any line parallel to l, then T is also a translation along l'.
The theorem states that if T is a translation along a line l, then T is also a translation along any line l' that is parallel to l.
To prove the theorem, let's consider a translation T along a line l. By definition, a translation preserves distances and directions. Now, let's consider a line l' that is parallel to l.
Since l' is parallel to l, any point on l' will have the same distance and direction from the corresponding point on l. In other words, for any point P on l', there exists a corresponding point Q on l such that the distance and direction between P and Q are the same.
Now, when we apply the translation T along l, it will move every point on l by the same distance and in the same direction. Since l' is parallel to l, the corresponding points on l' will also be moved by the same distance and in the same direction. Therefore, T is also a translation along l'.
Hence, we have proved that if T is a translation along a line l, then T is also a translation along any line l' that is parallel to l.

problem 6: find x and SR
By using midpoint theorem of triangles we can get the value of x as 6 and the length of SR is also 6 units.
A line segment constructed by joining the midpoints of two triangle sides will be parallel to the third side and have a length that is half that of the third side, according to the midpoint theorem, also known as the midline theorem.
The midpoint theorem, which divides the two sides equally rather than using midpoints, is generalized by the intercept theorem. The opposite of the theorem is also true. In other words, if you draw a line through the center of one triangle side and another triangle side, the third half of the triangle will be split in half.The triangle formed by three parallel lines crossing through a triangle's three midpoints is known as the medial triangle.Therefore from the above property we can write
IK=2SR
or, 3x-6 = 2(2x-6)
or, 3x-6 = 4x - 12
or, -x = -6
or, x = 6
Therefore the length of SR is 6 units and the length of x is also 6 units.
