C. ∆ABD ≅ ∆CBD by the SSS Postulate

Step-by-step explanation:

We can prove that ∆ABD and ∆CBD congruent by the SSS Postulate.

The SSS postulate states that of three sides in one triangle are congruent to three corresponding sides in another, therefore, the two triangles are congruent.

From the diagram shown,

AB ≅ CB,

AD ≅ CD

BD = BD

We have three sides in ∆ABD that are congruent to three corresponding sides in ∆CBD.

Therefore, ∆ABD ≅ ∆CBD by the SSS Postulate

Answer: Triangles ABD and CBD are congruent by the SSS Congruence Postulate.

We need to know the shape of the base and at least one other dimension, such as height or slant height. Therefore, Base Area is the area of the base and Height is the height of the pyramid.

The formula for the area of the base of a pyramid will depend on the shape of the base. If the base is a square with side length s, then the area of the base is given by:

Area = s^2

If the base is a rectangle with length l and width w, then the area of the base is given by:

Area = l*w

If the base is a triangle with base length b and height h, then the area of the base is given by:

Area = (1/2)bh

If the base is a polygon with n sides, then we can divide it into n triangles and sum up the areas of each triangle to find the area of the base. The formula for the area of a triangle can be used for each individual triangle.

Once we know the area of the base and the height of the pyramid, we can use the formula for the volume of a pyramid to find the total volume of the pyramid. The formula for the volume of a pyramid is given by:

Volume = (1/3)Base AreaHeight

where Base Area is the area of the base and Height is the height of the pyramid.

The correct option is B• "The LP has multiple optimal solutions". Because  feasible region, intersects with the objective function in multiple points.

The given linear programming (LP) problem consists of two constraints and two decision variables, x1 and x2. The objective function to be minimized is x1 + 2x2.

To determine the nature of the LP problem, we need to analyze its feasible region and objective function.

The first constraint, x1 + x2 ≤ 4, defines a region in the xy-plane that lies below the line x1 + x2 = 4. The second constraint, x1 - x2 ≥ 5, defines a region that lies to the right of the line x1 - x2 = 5. The feasible region is the intersection of these two regions.

By analyzing the feasible region, we can determine the potential optimal solutions. Since the feasible region is a bounded region, there are finite points within it. The objective function, x1 + 2x2, represents a straight line in the xy-plane with a positive slope. As long as this line intersects the feasible region, there will be multiple points of intersection, each representing a potential optimal solution.

Therefore, the LP problem has multiple optimal solutions because there are multiple points of intersection between the objective function and the feasible region.

The given system of equations is:
4x + y = 400
2x + 3y = 300

To find the coordinates of the vertices of the feasible region, we need to graph the lines and find the points of intersection. The feasible region is the shaded area bounded by the lines.


a. To find vertex 1, we need to find the intersection of the x-axis and the line 4x + y = 400. When y = 0, we get 4x = 400, which gives x = 100. So, vertex 1 is (100,0), and the lines forming this vertex are 4x + y = 400 and y = 0.

b. To find vertex 2, we need to find the intersection of the lines 4x + y = 400 and 2x + 3y = 300. Solving these equations simultaneously, we get x = 75 and y = 100. So, vertex 2 is (75,100), and the lines forming this vertex are 4x + y = 400 and 2x + 3y = 300.

c. To find vertex 3, we need to find the intersection of the y-axis and the line 2x + 3y = 300. When x = 0, we get 3y = 300, which gives y = 100. So, vertex 3 is (0,100), and the lines forming this vertex are 2x + 3y = 300 and x = 0.

d. To find vertex 4, we need to find the intersection of the x-axis and the line 2x + 3y = 300. When y = 0, we get 2x = 300, which gives x = 150. So, vertex 4 is (150,0), and the lines forming this vertex are 2x + 3y = 300 and y = 0.

To find the coordinates of the vertices, we used the method of graphing the lines and finding the points of intersection. Each vertex is formed by two lines that intersect at a point. We identified the equations of the lines forming each vertex and solved the system of equations to find the coordinates of the point of intersection.


The coordinates of the four vertices of the feasible region are:
Vertex 1: (100,0)
Vertex 2: (75,100)
Vertex 3: (0,100)
Vertex 4: (150,0)

The feasible region is the shaded area bounded by the lines and the vertices are the corners of the feasible region. The solution to the system of equations lies within this region.

Answer:

15, 21, 27

Step-by-step explanation:

\(a_n}\) = \(a_{1}\) + (n-1)d  

\(a_{n}\) is the number in the sequence we are looking for

\(a_{1}\)  This is the first term in the sequence that we do not know and we are looking for

n stands for the number of the term and d is the common difference.  We will put in all that we know and solve for the first term.

609 = \(a_{1}\) + (100-1)6  

609 =\(a_{1}\) + (99)6

609 = \(a_{1}\) + 594  Subtract 594 from both sides of the equation

15 = \(a_{1}\)

Now that we know that the first term is 15 we just add 6 to get the next term which is 21 and then add 6 again to get the last term 27.

The probability that a three-  number integer is separable by 7 is 3/20or 0.15.

To determine the probability that a three-  number number is separable by 7, we need to count the number of three-  number integers that are separable by 7 and  also divide that number by the total number of three-  number integers.

First, we need to find the lowest three-  number integer that's separable by 7. We know that 14 is the  lowest two-  number integer separable by 7, so the  lowest three-  number integer that's separable by 7 will be the coming multiple of 7, which is 105.    

Next, we need to find the largest three-  number integer that's separable by 7. The largest three-  number integer is 999, and the largest multiple of 7 that's  lower than or equal to 999 is 994.    So, we need to count the number of integers that are separable by 7 between 105 and 994.

We can do this by using the formula for the number of integers in an  computation sequence  

number of integers = ( last term-first term)/ common difference  

In this case, the first term is 105, the last term is 994, and the common difference is 7, so we have  

number of integers = ( 994- 105)/ 7 1 =  135  

Thus, there are 135 three-  number integers that are separable by 7.    

The total number of three-  number integers is 900( from 100 to 999). So, the probability that a three-  number integer is separable by 7 is    probability =  number of integers that are separable by 7/ total number of three-  number integers  probability
