Answer:

First one

Step-by-step explanation:

√40 is equal to  2√10, which can also be written as 6 (n) + 4 (given)

Answer of the statements is describe below.

Given that,

For general :

cost of admission  = $15

cost of per taco = $4

For VIP :

cost of admission  = $36

cost of per taco = $1.50

Therefore,

Since price of taco in VIP is less than General admission

Then Deric should choose VIP if he plan to buy 6 tacos.

The amount Deric have to spent = $55

As Deric wants to eat many tacos so he should go for VIP in which price of taco in VIP is less than General admission so he can buy more taco.

Since price of each taco in general admission = $4

Then he can buy 55/4  = 13.74 tacos in general admission

And  price of each taco in VIP = $1.5

Then he can buy 55/1.5 = 36.66 tacos in VIP

Since price of tacos in VIP is cheaper then he can buy

37 tacos nearly.

Answer:

2x^2 + x + 9 + (18/(x+2))

Step-by-step explanation:

To find the result when 2x^3 - 5x^2 - 9x + 18 is divided by x + 2 using the long division method, you can follow these steps:

Divide the first term of the dividend (2x^3) by the first term of the divisor (x). The result is 2x^2.

Multiply the divisor (x + 2) by 2x^2. The result is 2x^3 + 4x^2.

Subtract this result from the dividend (2x^3 - 5x^2 - 9x + 18). The result is -x^2 - 9x + 18

Bring down the next term of the dividend (-5x^2) and add it to the result from step 3. The result is -6x^2 - 9x + 18

Divide -6x^2 by -6x and the result is x.

Multiply the divisor by x. The result is x^2 + 2x

Subtract this result from the result of step 4. The result is -9x + 18

Bring down the next term of the dividend (-9x) and add it to the result from step 7. The result is -18x + 18

Divide -18x by -18 and the result is x

Multiply the divisor by x. The result is x^2 + 2x

Subtract this result from the result of step 8. The result is 18

Therefore, the quotient is 2x^2 + x + 9 and the remainder is 18

So the result when 2x^3 - 5x^2 - 9x + 18 is divided by x + 2 is 2x^2 + x + 9 + (18/(x+2))

Answer:

9(9b+2)

Step-by-step explanation:

The words 'the sum of' mean parenthesis.

And so 9 would be outside the parenthesis and then 9b and 2 would be inside.

The coordinate matrix of x in Rn relative to the basis b' is [5, 6]. To find the coordinate matrix of x in Rn relative to the basis b', we need to express x as a linear combination of the basis vectors in b'.

Given the basis b' = {(9, 0), (0, 4)} and the vector x = (45, 24), we want to find the scalars c1 and c2 such that:

x = c1*(9, 0) + c2*(0, 4)

By solving this equation, we can determine the values of c1 and c2, which represent the coordinates of x in the basis b'.

Expanding the equation, we have:

(45, 24) = (9c1, 0) + (0, 4c2)

Equating the corresponding components, we get two equations:

45 = 9c1   (equation 1)

24 = 4c2    (equation 2)

Solving equation 1, we find c1 = 5.

Solving equation 2, we find c2 = 6.

Therefore, the coordinate matrix of x in Rn relative to the basis b' is [5, 6].

In other words, the vector x can be expressed as a linear combination of the basis vectors in b' with coefficients 5 and 6, respectively.

Organizational culture is defined as the common beliefs, values, attitudes, customs, behaviors, and traditions that characterize a specific organization and determine the manner in which it functions. Organizational culture is set by the manager.

In a corporate or business environment, organizational culture can influence the daily operations of employees. It is the responsibility of managers to create a positive culture that emphasizes teamwork, respect, integrity, and accountability. The manager is an essential individual responsible for establishing and maintaining the organization's culture, which will ultimately define the employee's attitudes, behaviors, and productivity levels. He or she sets the tone for the workplace by creating an environment that fosters collaboration, innovation, and success. Employees need to feel connected to their workplace and colleagues to be motivated to do their best work. If a manager promotes a culture of fear, competition, or dishonesty, employees may become unmotivated or unproductive. An effective manager understands the importance of creating a positive workplace culture and works hard to establish and maintain it. Managers can establish a positive culture by encouraging open communication, providing regular feedback and recognition, fostering a sense of teamwork, creating opportunities for professional development, and setting high standards for performance. Managers must lead by example and demonstrate the behaviors and attitudes that they expect from their employees. They must hold themselves and others accountable for their actions, communicate expectations clearly, and provide support when needed. A positive organizational culture will enable an organization to attract and retain top talent, increase employee engagement, and promote collaboration and innovation.

The colorimeter detects the voltage created when sunlight penetrates the specimen, so the voltage created is exactly proportional to the absorbance of the sample.

When charged electrons (current) are forced through a conducting loop by the weight of an electrical raceway power source, they can perform tasks like lighting a lamp. In a nutshell, voltage equals pressure and is expressed in volts (V).

Here,

The voltage generated by the uv spectrophotometer is inversely proportionate to the amount of light present and linearly proportional to the sample's absorbance.

This indicates that as the sample's absorbance rises, so does the energy the colorimeter generates.

Similar to this, the voltage generated by the colorimeter rises as light strength falls.

The Beer-Lambert Law, which says that a sample's absorbance is directly proportional to its concentration of the absorbing substance and its path length and inversely proportional to incident light intensity, describes this connection.

The colorimeter detects the voltage created when sunlight penetrates the specimen, so the voltage created is exactly proportional to the absorbance of the sample.

Therefore, approximately 133 students need to be surveyed to estimate the mean number of texts sent during school hours with 99% confidence and a margin of error of at most 2 texts.

To determine the sample size needed to estimate the mean number of texts sent during school hours with a 99% confidence level and a margin of error of at most 2 texts, we can use the formula:

n = (Z * σ / E)^2

where:

n = sample size

Z = Z-score corresponding to the desired confidence level (99% confidence corresponds to Z ≈ 2.576)

σ = standard deviation of the population (9 texts, as given in the pilot study)

E = margin of error (2 texts)

Substituting the values into the formula, we get:

n = (2.576 * 9 / 2)^2 ≈ 132.6

The control limits for the R-chart, based on the given information, are UCL = 6.846 miles per hour and CL = 3.00 miles per hour.


To establish the control limits for the R-chart, we need to calculate the upper control limit (UCL) and the centerline (CL) for the range of maximum speeds.
Given:
Average sample mean (x) = 103.50 miles per hour
Average range (R) = 3.00 miles per hour
To calculate the control limits, we can use the following formulas:
UCL = D4 × R
CL = R
The constant D4 depends on the sample size. Since each sample contains 8 Eagletrons, we can refer to a statistical table to find the appropriate value of D4 for n = 8. For a sample size of 8, the value of D4 is approximately 2.282.
Plugging in the values, we can calculate the control limits:
UCL = D4 × R = 2.282 × 3.00 = 6.846 miles per hour (rounded to three decimal places)
CL = R = 3.00 miles per hour
Therefore, the control limits for the R-chart, based on the given information, are:
Upper Control Limit (UCL) = 6.846 miles per hour
Centerline (CL) = 3.00 miles per hour.

Answer:

$1,170

Step-by-step explanation:

Area around the pool = 20 x 30

Pool = 12 x 24

Carpet is sold $1.95 by square foot

Use formula A = bh

Plug it in: A = 20 x 30

So they need 600 sq ft of carpet.

Multiply 600 by 1.95 to get 1170

The total cost = $1,170

Answer:

$608.40

Step-by-step explanation:

Dimensions of pool: 12 ft by 24 ft

Dimensions of pool & cement walkways: 20 ft by 30 ft

The pool is a rectangle that sits inside the walkways. The area of the walkways (AW) is the area of the pool & walkways (the 20 ft by 30 ft rectangle) minus the area of the the pool (the 12 ft by 24 ft rectangle). Once we know the area of the just the walkways (AW), we multiply it by the price of the carpet too find the cost of the carpet.

area of walkways = area of pool & walkways - area of pool

AW = 20 ft * 30 ft - 12 ft * 24 ft

AW = 600 ft^2 - 288 ft^2

AW = 312 ft^2

The area of the walkways alone is 312 ft^2. Now we multiply it by the unit cost of carpet to find the cost of the carpet needed for the walkways.

cost = AW * unit rate

cost = 312 ft^2 * $1.95/ft^2

cost = $608.40

The expression which is equivalent to  \(\frac{\sqrt[7]{x^{2} } }{\sqrt[5]{y^{3} } }\) is \((x^{\frac{2}{7} } })({x^{-\frac{3}{5} } } )\). The 1st option is the answer

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we substitute the same value(s) for the variable(s)

Since \(\frac{\sqrt[7]{x^{2} } }{\sqrt[5]{y^{3} } }\)

In indices, ∛(x) = x^(1/3). Also,  ∛(x)² =  x^(2/3). Thus, the given expression can be written as:

\(\frac{\sqrt[7]{x^{2} } }{\sqrt[5]{y^{3} } } = \frac{x^{\frac{2}{7} } }{x^{\frac{3}{5} } } = (x^{\frac{2}{7} } })({x^{-\frac{3}{5} } } )\)
