The volume of the display case is 2161 1/8 cubic inches.To find the volume of a rectangular prism-shaped display case, we multiply its length, width, and height.

Given that the display case is 30 1/2 inches wide, 10 1/2 inches long, and 32 1/4 inches tall, we can calculate the volume as follows:

Volume = Length * Width * Height

Using the given measurements:

Volume = 10 1/2 inches * 30 1/2 inches * 32 1/4 inches

To simplify the calculation, we can convert the mixed numbers to improper fractions:

Volume = (21/2) inches * (61/2) inches * (129/4) inches

Next, we multiply the fractions:

Volume = (21/2) * (61/2) * (129/4) = 17289/8

The resulting fraction, 17289/8, is an improper fraction. To convert it back to mixed number form:

Volume = 2161 1/8 in³.

Step-by-step explanation:

Therefore, the statement represents an exponential function.

The given statement, "The value of a coin collection has increased by 3.25% annually over the last 20 years" represents an exponential function.Exponential functions refer to the mathematical operations where a constant is raised to the power of the variable x and this variable is the input, and the exponential function is the output.The given statement represents the exponential function because the value of the coin collection is increasing by 3.25% every year, which means it is compounding. Compounding interest is an essential feature of an exponential function since it increases in a compound way. The formula for compound interest is given as:`A=P(1+(r/n))^nt`Where,A is the final amount,P is the principal amount,r is the annual interest rate,n is the number of times the interest is compounded per year,t is the time in years.The compound interest formula reflects the exponential growth model because of the exponent. Also, the coin collection's value is continuously growing and, the longer it takes, the more its value increases.Therefore, the statement represents an exponential function.

Answer:

Step-by-step explanation:

∠g and ∠f are the interior angles on the same side of the transversal, therefore they're supplementary.

g + f = 180

4x + 3 + x + 17 = 180

5x + 20 = 180

5x = 180 − 20

5x = 160

x=1605=32

g = x + 17 = 32 + 17 = 49

Since ∠g and ∠e are corresponding angles, they're congruent.

g = e = 49

"Create a new matrix by copying elements greater than or equal to 25 from the original matrix."

To process a given n×m matrix with the provided rules, we need to create a new matrix that retains only the elements greater than or equal to 25 from the original matrix. We can start by initializing an empty new matrix of the same size as the original matrix. Then, we iterate through each element of the original matrix. For each element, we check if it is greater than or equal to 25. If it satisfies this condition, we copy that element to the corresponding position in the new matrix.

By applying this process for all elements in the original matrix, we generate a new matrix that contains only the elements greater than or equal to 25. The new matrix will have the same dimensions as the original matrix, and the elements in the new matrix will be placed in the same positions as their corresponding elements in the original matrix

A call that lasts for a length of 4 minutes would cost the same at either hotel.

For Hotel A: Cost = 2(4) + 5 = 13

For Hotel B: Cost = 4(4) - 3 = 13 minutes

We can determine the length of phone call that would cost the same at either hotel by the following equations.

Given:

Hotel A, cost of the call:

Cost for Hotel A = 2x + 5

For Hotel B, the cost of the call:

Cost for Hotel B = 4x - 3

For the length of the call that would cost the same at either hotel, we shall set these two equations equal to each other and solve for x:

2x + 5 = 4x - 3

Subtracting 2x from both sides, we get:

5 = 2x - 3

Adding 3 to both sides, we get:

8 = 2x

Dividing both sides by 2, we get:

x = 4

So, a call that lasts 4 minutes would cost the same at either hotel.

We can verify this, let's plug x = 4 into both equations:

For Hotel A: Cost = 2(4) + 5 = 13

For Hotel B: Cost = 4(4) - 3 = 13

2n^3 + 3n + 10 can be written as a polynomial of the form Q(n^3), where Q(n^3) represents the set of polynomials of the form a(n^3).

To prove that the expression 2n^3 + 3n + 10 is in the set Q(n^3), where Q(n^3) represents the set of polynomials of the form a(n^3), we need to show that the expression can be written in the form a(n^3) for some constant "a".

Let's start by factoring out the common factor of n^3 from each term:

2n^3 + 3n + 10 = n^3(2 + 3/n^2 + 10/n^3)

Now, let's rewrite the expression as a single term multiplied by n^3:

2n^3 + 3n + 10 = (2 + 3/n^2 + 10/n^3)n^3

Simplifying the expression inside the parentheses:

= (2n^3 + 3n^2 + 10n^3)/n^3

= (12n^3 + 3n^2)/n^3

= 12 + 3/n

ow, we can see that the expression can be written in the form a(n^3), where a = 12 and n^3 = 3/n.

Therefore, we have shown that 2n^3 + 3n + 10 can be written as a polynomial of the form Q(n^3), where Q(n^3) represents the set of polynomials of the form a(n^3).

The indefinite integral of 4t(1-16t^4) dt is: 2t^2 - (4/5)t^6 + c, Here, C is the constant of integration, which can be written as C = C1 + C2.

To find the indefinite integral of the given function, we'll integrate term by term. The given function is:

∫(4t - 16t^4) dt

Now we'll integrate each term:

∫4t dt - ∫16t^4 dt

For the first term, the power rule for integration states that ∫t^n dt = (t^(n+1))/(n+1) + C, where n is a constant:

∫4t dt = 4∫t^1 dt = 4(t^(1+1))/(1+1) + C1 = 4t^2/2 + C1 = 2t^2 + C1

For the second term, we'll apply the same rule:

∫16t^4 dt = 16∫t^4 dt = 16(t^(4+1))/(4+1) + C2 = 16t^5/5 + C2 = (16/5)t^5 + C2

Now combine the results:

∫(4t - 16t^4) dt = 2t^2 + (16/5)t^5 + C

Here, C is the constant of integration, which can be written as C = C1 + C2.

Quadratic regression is a statistical technique that is used to fit a parabolic equation to the data. The value of f (|x|) at xi = 12.55 is 45.5559.

The first step is to find the values of the constants a, b and c. We can use a calculator or software such as Microsoft Excel to find these values. Using Microsoft Excel, the values of the constants are found to be a = 0.2825, b = 1.758 and c = -14.556.

Next, we can use the derived quadratic function to find the value of f (|x|) at xi = 12.55. Since xi = 12.55 is not in the given data set, we need to find the value of yi corresponding to this value of xi.

We can use the derived quadratic function y = \(0.2825x^2 + 1.758x - 14.556\)

To find the value of yi at xi = 12.55.

Substituting x = 12.55 in the quadratic function, we get:

\(y = 0.2825(12.55)^2 + 1.758(12.55) - 14.556\)
y = 45.5559

The cost of direct labor per unit is $5.628 per apple.

To calculate the cost of direct labor per unit, we need to determine the total labor hours required to produce one unit of output and then multiply it by the wage rate.

Let's denote the labor hours required for the first resource as "L₁" and the labor hours required for the second resource as "L₂".

The first resource has a capacity of 2.1 apples per hour, and the demand is 1.6 apples per hour. Therefore, the labor hours required for the first resource per unit of output are:

L₁ = 1 apple / (2.1 apples/hour) = 0.4762 hours/apple (rounded to 4 decimal places)

The second resource has a capacity of 4.4 apples per hour, and the demand is 1.6 apples per hour. Therefore, the labor hours required for the second resource per unit of output are:

L₂ = 1 apple / (4.4 apples/hour) = 0.2273 hours/apple (rounded to 4 decimal places)

Now, let's calculate the total labor hours required per unit:

Total labor hours per unit = L₁ (first resource) + L₂ (second resource)

= 0.4762 hours/apple + 0.2273 hours/apple

= 0.7035 hours/apple (rounded to 4 decimal places)

Finally, to calculate the cost of direct labor per unit, we multiply the total labor hours per unit by the wage rate:

Cost of direct labor per unit = Total labor hours per unit * Wage rate

= 0.7035 hours/apple * $8/hour

= $5.628 per apple (rounded to 3 decimal places)

Answer:

Step-by-step explanation:

\(5x + y = 28\)

\(x + y = 8\)

Solve the equation for y by moving 'x' to R.H.S and changing its sign

\(5x + y = 28\)

\(y = 2 - x\)

Substitute the given value of y into the equation 5x + y = 28

\(5x + 2 - x = 28\)

Solve the equation for x

Collect like terms

\(4x + 2 = 28\)

Move constant to R.H.S and change its sign

\(4x = 28 - 2\)

Subtract the numbers

\(4x = 26\)

Divide both sides of the equation by 4

\( \frac{4x}{4} = \frac{26}{4} \)

Calculate

\(x = \frac{26}{4} \)

Reduce the numbers with 2

\(x = \frac{13}{2} \)

Now, substitute the given value of x into the equation y = 2 - x

\(y = 2 - \frac{13}{2} \)

Solve the equation for y

\(y = - \frac{9}{2} \)

The possible solution of the system is the ordered pair ( x , y )

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

Let's check if the given ordered pair is the solution of the system of equation:

plug the value of x and y in both equation

\(5 \times \frac{13}{2} - \frac{9}{2} = 28\)

\( \frac{13}{2} - \frac{9}{2} = 2\)

Simplify the equalities

\(28 = 28\)

\(2 = 2\)

Since , all of the equalities are true, the ordered pair is the solution of the system.

\((x \:, y \: ) = ( \frac{13}{2} \: , - \frac{9}{2}) \)

Answer:

\(\boxed{x=6.5} \\ \boxed{y=-4.5}\)

Step-by-step explanation:

5x + y = 28

x + y = 2

Subtract both equations. (eliminating y variable)

4x + 0 = 26

4x = 26

Divide both sides by 4.

x = \(\frac{26}{4}\)

x = 6.5

Plug x as 6.5 in the second equation and solve for y.

6.5 + y = 2

Subtract 6.5 on both sides.

6.5 - 6.5 + y = 2 - 6.5

y = -4.5

In doing a quantity takeoff for 100 square feet of single wythe concrete masonry wall, with a thickness of 8", we would need  14.06 8x8x16 block and 10.14 cubic feet mortar.

Number of blocks:

Since each block is 8x8x16 inches, the volume of one block is:

Volume of one block = Length x Width x Height

                                   = 8 inches x 8 inches x 16 inches

                                   = 1024 cubic inches

To calculate the number of blocks needed, we divide the wall area by the area of one block:

Number of blocks = Wall area in square inches / Area of one block

                              = 14,400 square inches / 1024 cubic inches

                              ≈ 14.06

Rounding to the nearest whole number, the correct answer is 14 blocks.

Amount of mortar:

To determine the amount of mortar needed, we multiply the wall area by the joint thickness:

Volume of mortar = Wall area x Joint thickness

                              = 100 square feet x 1 square foot/144 square inches x 8 inches x 3/8 inches
