An expression represents the product of 3 and ((5/4)n+1.8) is 3.75n + 5.4

The correct answer is an option (D)

Consider the expression  ((5/4)n + 1.8)

First we write the fraction 5/4 in the decimal form.

5/4 = 1.25

So, the expression ((5/4)n + 1.8) becomes,

((5/4)n + 1.8)

=   (1.25 n + 1.8)                         ..........(1)

Now consider the product of 3 and ((5/4)n + 1.8)

3 ×  ((5/4)n + 1.8)

= 3 × ((1.25)n + 1.8)                          ............(from statement (1))

= (3 × (1.25 n)) + (3 × 1.8)

= (3 × 1.25)n + 5.4

= 3.75n + 5.4

Thus, 3 ×  ((5/4)n + 1.8) = 3.75n + 5.4

The correct answer is an option (D)

Now we can use the formula for cos (theta) to find the angle of view:
cos(theta) = adjacent/hypotenuse = 20/28.28
theta = cos^-1(20/28.28) = 45 degrees
So the angle of view of the sniper is 45 degrees.

To find the angle of view for the sniper on top of a building, we can use the trigonometric functions you provided. In this case, we know the height of the building (20 meters) and the horizontal distance (also 20 meters).

Let's denote the height as 'y' and the horizontal distance as 'x'. Given the information, y = 20 meters and x = 20 meters.

We can use the tangent function (tan theta) to find the angle:

Tan theta = y/x

Tan theta = 20/20 = 1

Now, we need to find the angle (theta) by taking the inverse tangent (arctan) of the result:

theta = arctan(1)

Using a calculator or conversion table, we find that:
cos(theta) = adjacent/hypotenuse = 20/28.28
theta = cos^-1(20/28.28) = 45 degrees
theta ≈ 45°

So, the angle of view for the sniper on top of the 20-meter high building with a 20-meter slope is approximately 45 degrees.

Step-by-step explanation:

False. An n × n matrix that is orthogonally diagonalizable does not necessarily have to be symmetric. A matrix is said to be orthogonally diagonalizable if it can be expressed as PDP^T, where P is an orthogonal matrix and D is a diagonal matrix.

For a matrix to be symmetric, it must satisfy the condition A = A^T, where A^T denotes the transpose of A. While it is true that symmetric matrices are always orthogonally diagonalizable, the converse is not necessarily true. There exist non-symmetric matrices that can still be orthogonally diagonalized. An example of such a matrix is the following:

  [1  2]

A = [3 4]

This matrix is not symmetric, as A^T is:

  [1  3]

A^T = [2 4]

However, it is still orthogonally diagonalizable. The matrix A can be diagonalized as:

A = PDP^T, where P = [0.8507 -0.5257]

[0.5257 0.8507]

          and D = [-0.3723   0     ]

                    [ 0      5.3723]

Therefore, it is not necessary for an n × n matrix that is orthogonally diagonalizable to be symmetric.

The effective price paid by the company after taking account of hedging would be $63.50, which is the August futures price on July 1. Calculate the profit or loss on the futures contracts and subtract that from the spot price on July 1, to determine the effective.

By entering into futures contracts on March 1, the company was able to lock in the price of $59 for the commodity, when the spot price was $60 and the futures price was $59, the difference between the futures price and the spot price on March 1 was $1 ($60 - $59), so the company had to pay an extra $1 per unit to hedge its purchase.

When the spot price increased to $64 on July 1, the company was still able to purchase the commodity at the lower hedged price of $59, plus the cost of the futures contract, which resulted in an effective price of $63.50. Overall, hedging helped the company mitigate the risk of price volatility and ensured a more predictable cost for the commodity purchase.

Effective price = Spot price - Profit from futures contracts

Effective price = $64 - $0.50(The difference between the futures price and the spot price on July 1 was $0.50 ($64 - $63.50))

Effective price = $63.50 per unit

Therefore, the effective price paid by the company after taking into account hedging was $63.50 per unit.

Yes, the new method for detecting avobenzone in sunscreen is valid/accurate at a 95% confidence level.

The standard reference material provided by the FDA contains 0.250 mg of avobenzone per gram of sunscreen. The working group analyzed the standard and obtained measurements of avobenzone content in six samples, which were found to be 0.256, 0.279, 0.328, 0.305, 0.312, and 0.230 µg/g.

To determine the validity and accuracy of the new detection method, we need to assess if the measurements obtained from the samples are within an acceptable range of the known avobenzone content provided by the standard.

At a 95% confidence level, we can calculate a confidence interval to evaluate the accuracy of the new method. The confidence interval is a range within which we can reasonably expect the true avobenzone content of the sunscreen samples to fall. If the known avobenzone content provided by the standard falls within this confidence interval, it indicates that the new method is valid and accurate.

By performing the necessary calculations, we can determine the confidence interval. Comparing the range of the measurements obtained from the samples (0.230 to 0.328 µg/g) with the known avobenzone content provided by the standard (0.250 mg/g), we find that the measurements overlap with the known value. Therefore, we can conclude that the new method is valid/accurate for the detection of avobenzone in sunscreen at a 95% confidence level.

Answer:

The process capability index for this system is 0.9103

Step-by-step explanation:

Upper specification = 1.649 inches

Lowe Specification = 1.507 inches

Mean = 1.57 inches

Standard Deviation = 0.026 inches

Process Capability Index = PCI

PCI = (Upper specification - lower specification)/6(standard deviation)

So, we get,

PCI = (1.649 - 1.507)/((6)(0.026))

PCI = 0.142/0.156

PCI = 0.9102564

To four decimal places, we get,

PCI = 0.9103

Given:

\(a_1=-4\) and \(a_n=a_{n-1}+9\) where \(n\geq 2\).

To find:

The explicit formula for the given recursive formula.

Solution:

We know that recursive formula of an AP is:

\(a_n=a_{n-1}+d\)

Where, d is the common difference.

We have,

\(a_n=a_{n-1}+9\)

Here, d=9.

The first term of the AP is \(a_1=-4\).

The explicit formula for an AP is:

\(a_n=a_1+(n-1)d\)

Substituting \(a_1=-4\) and \(d=9\), we get

\(a_n=-4+(n-1)9\)

\(a_n=-4+9n-9\)

\(a_n=-13+9n\)

Therefore, the required explicit formula for the given sequence is \(a_n=-13+9n\).

-$14,469 is the Overapplied Manufacturing Overhead. We can calculate it in the following manner.

To calculate the plantwide predetermined overhead rate, we need to divide the total estimated manufacturing overhead costs by the estimated total direct labor-hours:

Plantwide Predetermined Overhead Rate = (Estimated Fixed Manufacturing Overhead + Estimated Variable Manufacturing Overhead) / Estimated Total Direct Labor-Hours

Plantwide Predetermined Overhead Rate = ($558,000 + ($3.00 per direct labor-hour x 38,000 direct labor-hours)) / 38,000 direct labor-hours

Plantwide Predetermined Overhead Rate = $672,000 / 38,000 direct labor-hours

Plantwide Predetermined Overhead Rate = $17.68 per direct labor-hour

To calculate the total manufacturing overhead cost applied to production, we multiply the actual direct labor-hours by the plantwide predetermined overhead rate:

Total Manufacturing Overhead Applied = Actual Direct Labor-Hours x Plantwide Predetermined Overhead Rate

Total Manufacturing Overhead Applied = 44,500 direct labor-hours x $17.68 per direct labor-hour

Total Manufacturing Overhead Applied = $787,960

To calculate the under- or overapplied manufacturing overhead, we subtract the total manufacturing overhead applied from the actual manufacturing overhead costs:

Under- or Overapplied Manufacturing Overhead = Actual Manufacturing Overhead Costs - Total Manufacturing Overhead Applied

Under- or Overapplied Manufacturing Overhead = $773,491 - $787,960

Under- or Overapplied Manufacturing Overhead = -$14,469

The negative amount indicates that the actual manufacturing overhead costs were higher than the amount applied to production.

The equation of the tangent line to the path of the particle at t = 2 is (option) b. y = x - 3.

To find the equation of the tangent line at t = 2, we need to find the values of x(2) and y(2) and the slopes of the tangent line. From the given parametric equations, we have:

x(t) = -ln(t) + C1

y(t) = -2/t + C2

where C1 and C2 are constants of integration. To find C1 and C2, we use the initial conditions x(2) = 1 and y(2) = -2:

1 = -ln(2) + C1

-2 = -2/2 + C2

C1 = 1 + ln(2)

C2 = -1

Differentiating x(t) and y(t) with respect to t, we get:

dx/dt = -1/t

dy/dt = 4/t^3

At t = 2, we have dx/dt = -1/2 and dy/dt = 1/4. The slope of the tangent line is given by dy/dx, which is:

dy/dx = (dy/dt)/(dx/dt) = (-1/4)/(-1/2) = 1/2

Therefore, the equation of the tangent line at t = 2 is:

y - (-2) = (1/2)(x - 1)

y = x - 3
