Answer:

2ft

Step-by-step explanation:

The tide doesn't effect the part of ladder that is underwater that is always 2ft

How much of the ladder that will be underwater is 7 ft.

Since the ladder is 10 ft long and its last two feet are submerged under water, this implies that 2 ft of the ladder are submerged under water.

When the tide rises by five feet, the part of the ladder that would be under water is 2 ft + 5ft = 7ft.

So, how much of the ladder that will be underwater is 7 ft.

the correct value of r can be calculated using the formula r = x/16, where x is the number of red balls in a particular column of the table. As long as the ratio of red balls to blue balls is constant in each column, this formula will hold true.

How to solve the ratio?

According to the problem statement, the ratio of red balls to blue balls is constant in each column of the table. This means that for any given column, the ratio of red balls to blue balls will remain the same, regardless of the total number of balls in the column.

Let's assume that there are x red balls and 16 blue balls in a particular column of the table. According to the problem statement, the ratio of red balls to blue balls in that column is constant, which means that:

x/16 = r/1

Here, r is the number of red balls corresponding to 16 blue balls, which is what we need to find. We can solve for r by cross-multiplying and simplifying:

x = 16r

r = x/16

So, if we know the number of red balls in a particular column, we can easily calculate the corresponding value of r by dividing that number by 16.

To summarize, the correct value of r can be calculated using the formula r = x/16, where x is the number of red balls in a particular column of the table. As long as the ratio of red balls to blue balls is constant in each column, this formula will hold true.

The unit vector that lies in the xy plane at an angle of 155 degrees from the x axis with a positive y component is (0.4237, 0.9055).

A unit vector is a vector with a magnitude of 1. To find the unit vector that lies in the xy plane at an angle of 155 degrees from the x axis with a positive y component, we can use the formula for a two-dimensional vector in polar coordinates:

r = (cos(θ), sin(θ))

where r is the unit vector, θ is the angle in radians, and cos(θ) and sin(θ) are the x and y components, respectively.

First, we need to convert the angle from degrees to radians:

θ = 155° * (π / 180°) = 2.68 radians

Next, we can plug in the values into the formula:

r = (cos(2.68), sin(2.68)) = (0.4237, 0.9055)

So, the unit vector that lies in the xy plane at an angle of 155 degrees from the x axis with a positive y component is (0.4237, 0.9055).

To summarize, the process for finding a unit vector in the xy plane at an angle from the x axis is:

The decimal equivalent in base 10 of the largest number a system can represent depends on the number of digits available and the base value.

In any number system, the largest number that can be represented depends on the number of available digits and the base value. For example, in the decimal system (base 10), we have ten digits from 0 to 9. With these digits, the largest number we can represent with n digits is (10ⁿ- 1).

In general, if a system has a base value of b and n digits available (0 to b-1), the largest number it can represent is (bⁿ - 1). This is because the value of each digit position increases exponentially with the base value. The leftmost digit represents the base raised to the power of (n-1), the second leftmost digit represents the base raised to the power of (n-2), and so on.

For example, in the binary system (base 2), we have two digits 0 and 1. With just one digit, we can represent the numbers 0 and 1. With two digits, we can represent (2² - 1) = 3, which is the largest number in base 2 with two digits.

If demand or annual usage increases by 10 percent, the Economic Order Quantity (EOQ) will increase. The EOQ model is used in inventory management to determine the optimal order quantity that minimizes total inventory costs.

The Economic Order Quantity (EOQ) is a model used in inventory management to determine the optimal order quantity that minimizes total inventory costs. It takes into account factors such as demand, holding costs, and ordering costs. When demand or annual usage increases by 10 percent, it means that more units are being consumed or sold within a given time period.

With an increase in demand, the EOQ will also increase. This is because the EOQ formula takes into consideration the trade-off between holding costs and ordering costs. Holding costs are the costs associated with holding inventory, such as warehousing and insurance, while ordering costs are the costs incurred when placing an order, such as administrative and transportation costs.

When demand increases, more units need to be ordered to meet the higher demand. This results in an increase in ordering costs, as more frequent orders will need to be placed. Consequently, the EOQ will increase to find the new optimal order quantity that balances the increased ordering costs with the holding costs.

In summary, if demand or annual usage increases by 10 percent, the EOQ will increase due to the need to order more frequently to meet the higher demand, resulting in increased ordering costs. This adjustment ensures that the inventory management system remains efficient and cost-effective.

The volume of the solid described by the principal coordinates (cylindrical coordinates) 0 ≤ r/√3 ≤ z ≤ 1 is (π/3) - (π/12√3).

To find the volume of the solid, we use the triple integral in cylindrical coordinates. The limits of integration are as follows: 0 ≤ r ≤ √3z, 0 ≤ θ ≤ 2π, and 0 ≤ z ≤ 1.

The volume element in cylindrical coordinates is given by dV = r dz dr dθ.

The integral for the volume of the solid is then:

V = ∫∫∫ r dz dr dθ from z=0 to z=1, θ=0 to θ=2π, and r=0 to r=√3z.

Integrating with respect to θ and r, we get:

V = ∫0^1∫0^√3z∫0^2π r dz dr dθ

= 2π∫0^1∫0^√3z zr dr dz

= 2π∫0^1 z/2 * (3z)^(3/2) dz

= 2π/5 [3^(5/2) - 3]

Therefore, the volume of the solid is (π/3) - (π/12√3).

Step-by-step explanation:

The relationship between the mean and median can provide information about the shape of the distribution and the presence of outliers.

The mean and median can be either close to the same value or very different from one another, depending on the distribution of the data.

If the data is approximately symmetric, with no extreme values, then the mean and median will be close to each other. In this case, the data is evenly distributed around the central tendency of the data, so both measures provide a similar representation of the central value.

However, if the data is skewed, with one tail longer than the other, or if there are extreme values (outliers) present in the data, then the mean and median will be different.

In this case, the mean is pulled in the direction of the skew or outliers, while the median remains unaffected.

As a result, the mean may not provide an accurate representation of the central tendency of the data.

To find the probability that the average length of a randomly selected bundle of steel rods is between 111.2 cm and 112.1 cm, we can use the central limit theorem, which states that the distribution of sample means will be approximately normal regardless of the shape of the population distribution, as long as the sample size is large enough.

In this case, the sample size is 25, which is considered large enough for the central limit theorem to apply.

The mean of the distribution of sample means is equal to the population mean, which is 111.7 cm.

The standard deviation of the distribution of sample means, also known as the standard error, can be calculated by dividing the population standard deviation by the square root of the sample size. In this case, the standard deviation is 0.8 cm, and the sample size is 25, so the standard error is 0.8 / sqrt(25) = 0.16 cm.

To find the probability, we need to calculate the z-scores for the lower and upper limits of the desired range and then use a standard normal distribution table or calculator.

The z-score for 111.2 cm can be calculated as (111.2 - 111.7) / 0.16 = -3.125.

The z-score for 112.1 cm can be calculated as (112.1 - 111.7) / 0.16 = 2.5.

Using the standard normal distribution table or calculator, we can find the corresponding probabilities associated with these z-scores.

The probability that the average length of a randomly selected bundle of steel rods is between 111.2 cm and 112.1 cm is the difference between the two probabilities.

Bank B has a basic fee of $9.95 per month and a bill paying fee of $5.95 per month. It has a limit of 20 checks written per month, with a cost of $1 per bill beyond the limit. The total annual cost for Bank B is $174.40.

To compare the cost of online banking, Tim Worker needs to consider various factors, including the basic monthly fee, bill paying monthly fee, limits on the number of checks written, and cost per bill beyond the limit. The basic fee is the amount charged by the bank for providing access to online banking services.

The bill paying fee is charged for each payment made through the online bill pay service. The limit on the number of checks written is the maximum number of checks that can be written in a given month without incurring additional charges. The cost per bill beyond the limit is the amount charged for each bill payment made beyond the specified limit.

Bank B has a basic fee of $9.95 per month and a bill paying fee of $5.95 per month. It has a limit of 20 checks written per month, with a cost of $1 per bill beyond the limit. To calculate the annual cost for Bank B, we can multiply the basic fee and bill paying fee by 12 and add the cost of any additional bills beyond the limit, multiplied by the cost per bill and the number of months in a year.

The total annual cost for Bank B is $174.40, calculated as follows:

Basic fee = $9.95 * 12 = $119.40

Bill paying fee = $5.95 * 12 = $71.40

Cost of bills beyond limit = $1 * (35 - 20) * 12 = $180

Total cost = $119.40 + $71.40 + $180 = $371.80

x = π/3 and x = 2π/3.

To find the solutions to the equation -8sin(5x) = -4√3 on the interval 0 ≤ x < 2π, we can start by isolating the sine term.

Dividing both sides of the equation by -8, we have:

sin(5x) = √3/2

Now, we can find the angles whose sine is √3/2. These angles correspond to the angles in the unit circle where the y-coordinate is √3/2.

Using the special angles of the unit circle, we find that the solutions are:

x = π/3 + 2πn

x = 2π/3 + 2πn

where n is an integer.

Since we are given the interval 0 ≤ x < 2π, we need to check which of these solutions fall within that interval.

For n = 0:

x = π/3

For n = 1:

x = 2π/3

Both solutions, π/3 and 2π/3, fall within the interval 0 ≤ x < 2π.

The equation \(4x^2u^n + (1-x^2)u = 0\) has two solutions. One solution is given by \(u_1 = x^{1/2}\left(1 + \frac{x^2}{16} + \frac{x^4}{1024} + \dots\right)\). The other solution is not provided in the given question.

To find the solutions, we can rewrite the equation as \(u^n = -\frac{1-x^2}{4x^2}u\). Taking the square root of both sides gives us \(u = \pm\left(-\frac{1-x^2}{4x^2}\right)^{1/n}\). Now, let's focus on finding the positive solution.

Expanding the expression inside the square root using the binomial series, we have:

\[\left(-\frac{1-x^2}{4x^2}\right)^{1/n} = -\frac{1}{4^{1/n}x^{2/n}}\left(1 + \frac{(1-x^2)}{4x^2}\right)^{1/n}\]

Since \(|x| < 1\) (as \(x\) is a fraction), we can use the binomial series expansion for \((1+y)^{1/n}\), where \(|y| < 1\):

\[(1+y)^{1/n} = 1 + \frac{1}{n}y + \frac{1-n}{2n^2}y^2 + \dots\]

Substituting \(y = \frac{1-x^2}{4x^2}\), we get:

\[\left(-\frac{1-x^2}{4x^2}\right)^{1/n} = -\frac{1}{4^{1/n}x^{2/n}}\left(1 + \frac{1}{n}\cdot\frac{1-x^2}{4x^2} + \frac{1-n}{2n^2}\cdot\left(\frac{1-x^2}{4x^2}\right)^2 + \dots\right)\]

Simplifying and rearranging terms, we find the positive solution as:

\[u_1 = x^{1/2}\left(1 + \frac{x^2}{16} + \frac{x^4}{1024} + \dots\right)\]

The second solution is not provided in the given question, but it can be obtained by considering the negative sign in front of the square root.
