The following can be shown about the diagonals of parallelogram PQRS to compare the proof that diagonals of a parallelogram bisect each other: B. PR and SQ have the same midpoint.
What is a parallelogram?In Mathematics and Geometry, a parallelogram is a geometrical figure (shape) and it can be defined as a type of quadrilateral and two-dimensional geometrical figure that has two (2) equal and parallel opposite sides.
In order for any quadrilateral to be considered as a parallelogram, two pairs of its parallel opposite sides must be equal (congruent). This ultimately implies that, the diagonals of a parallelogram would bisect one another only when their midpoints are the same:
(Line segment PR)/2 = (Line segment SQ)/2

Question 2 A project has a useful life of 10 years, and no salvage value. The firm uses an interest rate of 12 % to evaluate engineering projects. A project has uncertain first costs and annual
Answers
The project has a useful life of 10 years and no salvage value. To evaluate engineering projects, the firm uses an interest rate of 12%. Since the first costs and annual costs of the project are uncertain, it is important to calculate the Net Present Value (NPV) to determine the project's profitability.
To calculate the NPV, we need to discount the future cash flows of the project to their present value. The formula for calculating NPV is:
\(NPV = Cash Flow / (1 + r)^t\)
where r is the interest rate and t is the time period. In this case, we need to calculate the NPV for each year of the project's useful life. Since there is no salvage value, the cash flow will be the negative of the annual cost of the project.
Let's say the annual cost is $10,000. We can calculate the NPV for each year using the formula mentioned above. The NPV for year 1 would be:
NPV1 = -$10,000 / (1 + 0.12)^1 = -$8,928.57 (negative because it represents an outgoing cash flow)
Similarly, we can calculate the NPV for each year of the project's useful life. To determine the total NPV, we sum up the NPVs for each year.
By calculating the NPV, we can assess whether the project is financially viable or not. A positive NPV indicates that the project is profitable, while a negative NPV suggests that the project may not be financially feasible.
In summary, to evaluate the profitability of the project with uncertain costs, we need to calculate the NPV by discounting the future cash flows to their present value using the interest rate.

A fast food restaurant executive wishes to know how many fast food meals adults eat each week. They want to construct a 90% confidence interval for the mean and are assuming that the population standard deviation for the number of fast food meals consumed each week is 1.4. The study found that for a sample of 1271 adults the mean number of fast food meals consumed per week is 3. Construct the desired confidence interval. Round your answers to one decimal place.
Answers
The confidence interval which shows 90% confidence level for the mean and assumed standard deviation is (2.94 meals, 3.0565 meals).
Given standard deviation=1.4. Sample size =1271, mean=3.
We have to find the confidence interval for 90% confidence level.
We have to find out α level that is the subtraction of 1 by the confidence interval divided by 2.
α=(1-0.90)/2
=0.05
Now we have to find z in the z table as such z has a p value of 1-α so it is z with p value of 1-0.05=0.95
Z=1.44 from z table.
Now find M as such that
M=z* st/\(\sqrt{n}\)
where st is standard deviation ,n is sample size.
M=1.44*1.4/\(\sqrt{1271}\)
=1.44*1.4/35.65
=2.016/35.65
=0.0565
Lower end= mean -M
=3-0.0565
=2.94
Upper end=Mean+ M
=3+0.0565
=3.0565
Hence the confidence interval showing 90% confidence level is (2.94,3.0565).

Find two positive numbers satisfying the given requirements. The sum of the first and twice the second is 320 and the product is a maximum. _______(first number) _______(second number)
Answers
To find two positive numbers that satisfy the given requirements, we'll let the first number be denoted as 'x' and the second number as 'y.' We are given that the sum of the first number and twice the second number is 320. By expressing the product as a function of 'x' and solving for its maximum value, we can determine the two positive numbers that satisfy the given conditions.
Let's assume the first positive number is 'x' and the second positive number is 'y.' According to the problem, we have the following equation: x + 2y = 320.
To maximize the product of the two numbers, we need to express it as a function of 'x' only. The product, denoted as P, can be expressed as P = x * y.
We can use the equation x + 2y = 320 to rewrite y in terms of x: y = (320 - x) / 2. Substituting this expression into the product function, we get P = x * [(320 - x) / 2].
To find the maximum value of P, we can take the derivative of P with respect to x and set it equal to zero. Differentiating P with respect to x, we have dP/dx = (320 - 2x) / 2.
Setting dP/dx equal to zero and solving for x, we get 320 - 2x = 0, which simplifies to x = 160.
Substituting the value of x back into the equation x + 2y = 320, we find 160 + 2y = 320. Solving for y, we get y = 80.
Therefore, the two positive numbers that satisfy the given requirements are x = 160 and y = 80.

What is HCF?Highest Common Factor is the full name for HCF in mathematics.
According to the laws of mathematics, the highest positive integer that divides two or more positive integers without leaving a residual is known as the greatest common divisor, or gcd.
What is LCM?Least Common Multiple is the full name for LCM in mathematics.
LCM (a,b) in mathematics stands for the least common multiple, or LCM, of two numbers, such as a and b. The smallest or least positive integer that is divisible by both a and b is known as the LCM.
We need to know the size of the pieces in order to calculate how many people can be fed equal-sized pieces of cake from a 16 by 18-inch cake.
Assume that each piece is a square with sides measuring "x" in length. Each piece's area would be x², and the cake's overall area would be 16 x 18 inches, or 288 square inches.
We must divide the entire area of the cake by the area of each piece to determine the maximum number of pieces that can be cut from the cake:
288 / x² = (16*18) / x² = 288 / x²
Choosing a "x" value that evenly splits into 16 and 18 is necessary if we want every piece to be the exact same size. Since 2 is the greatest possible value, we can divide the cake into 8 rows of 9 squares, yielding a total of 72 pieces.
As a result, a cake measuring 16 inches by 18 inches can be divided into 72 equal-sized pieces, each measuring 2 inches by 2 inches.

What is area?A two-dimensional figure, form, or planar lamina's area is a measurement of how much space it takes up in the plane.
To find out how many people can be served equal-sized pieces of cake from a cake that is 16 inches by 18 inches, we need to first determine the size of each piece of cake.
The total area of the cake is:
16 inches x 18 inches = 288 square inches
To divide the cake into equal-sized pieces, we need to determine the size of each piece. Let's assume we want each piece to be a square. To find the size of each square, we need to find the square root of the total area of the cake:
√(288 square inches) ≈ 16.97 inches
Since we want the pieces to be exactly the same size, we'll round down to the nearest inch, which gives us:
Each piece of cake will be approximately 16 inches by 16 inches.
To find out how many people can be served equal-sized pieces of cake, we need to divide the total area of the cake by the area of each piece:
288 square inches ÷ (16 inches x 16 inches) = 18
Therefore, we can serve 18 people equal-sized pieces of cake from a cake that is 16 inches by 18 inches, assuming each piece is a square and we want the pieces to be exactly the same size.

prove that if k is an infinite field then for polynomial f with k coefficients if f on all x in k^n is 0 then f is a zero polynomial
Answers
We can conclude that if k is an infinite field and a polynomial f with k coefficients is equal to 0 for all x in kⁿ, then f is a zero polynomial.
To prove that if k is an infinite field and a polynomial f with k coefficients is equal to 0 for all x in kⁿ, then f is a zero polynomial, we can use the concept of polynomial interpolation.
Suppose f(x) is a polynomial of degree d with k coefficients, and f(x) = 0 for all x in kⁿ.
Consider a set of d+1 distinct points in kⁿ, denoted by \({x_1, x_2, ..., x_{d+1}}\). Since k is an infinite field, we can always find a set of d+1 distinct points in kⁿ.
Now, let's consider the polynomial interpolation problem. Given the d+1 points and their corresponding function values, we want to find a polynomial of degree at most d that passes through these points.
Since f(x) = 0 for all x in kⁿ, the polynomial interpolation problem can be formulated as finding a polynomial g(x) of degree at most d such that \(g(x_i) = 0\) for all i from 1 to d+1.
However, the polynomial interpolation problem has a unique solution. Therefore, the polynomial f(x) and the polynomial g(x) must be identical because they both satisfy the interpolation conditions.
Since f(x) = g(x) and g(x) is a polynomial of degree at most d that is zero for d+1 distinct points, it must be the zero polynomial.
Therefore, we can deduce that f is a zero polynomial if kⁿ is an infinite field and a polynomial f with k coefficients equals 0 for all x in kⁿ.

Parallel Lines
1. Angles ∠1 and ∠2 are linear because they form a line. The sum of their measures is 180°: ∠1 + ∠2 = 180°.
Given m∠2 = 120°, then
m∠1 = 180° - m∠2 = 180° - 120° = 60°
Thus:
m∠1 = 60°
2. Angles ∠1 and ∠5 are called corresponding pair of angles.
3. We have found that m∠1 = 60° and we are given that m∠5 = 60°.
If corresponding angles are congruent, then the lines must be parallel.
4. Given that m∠5 = 60° and ∠7 and ∠5 are linear, thus m∠7 = 120°.
