The answer is 2.6825  cm, which is not one of the given options. Therefore, the correct answer is E. none of these.

The bulk modulus, B is defined as:

B = (P / ΔV / V), where P is the pressure applied, ΔV is the change in volume, and V is the original volume.

For a cube, the change in volume, ΔV is related to the change in length, ΔL by:

\(\sf \Delta V = \Delta L^3\).

Given that the cube has 2.0 cm sides, the original volume, V is:

\(\sf V = (2.0 \ cm)^3 = 8.0 \ cm^3\).

The pressure applied is \(\sf P = 2.0 \times 10^5\) Pa and the bulk modulus is \(\sf B = 4.7 \times 10^5 \ N/m^2\).

We can rearrange the bulk modulus formula to solve for ΔL as:

\(\sf \Delta L = \huge \text(\dfrac{P}{B} \huge \text) \times \dfrac{V}{3}\).

Substituting the values, we get:

\(\sf \Delta L = (2.0 \times 10^5 \ \dfrac{Pa}{4.7} \times 10^5\ N/m^2) \times \dfrac{8.0 \ cm^3}{3} = 0.6825 \ cm\)

Therefore, the final length of any side of the cube is:

\(\sf L = 2.0 \ cm + \Delta L = 2.0 \ cm + 0.6825 \ cm = 2.6825 \ cm\)

Step-by-step explanation:

To determine which payment plan the real estate investor would prefer, we need to compare the present value of each payment option. Assuming a discount rate of 0%, meaning no time value of money is considered, we can directly compare the payment amounts.

1. Payment of $2,000 at the first of each month: This results in a total payment of $24,000 over the 12-month lease.

2. Upfront payment of $24,000: This option requires paying the full amount at the beginning of the lease.

3. Payment of $2,000 at the end of each month: Similar to option 1, this results in a total payment of $24,000 over the 12-month lease.

4. Upfront payment of $12,000 and $12,000 half-way through the lease: This option requires paying $12,000 at the beginning of the lease and another $12,000 halfway through the lease.

Since all the payment options have a total cost of $24,000, the real estate investor would likely prefer the payment plan that offers more flexibility or matches their cash flow preferences. Options 1 and 3 provide the investor with the option to pay monthly, while options 2 and 4 require a larger upfront payment. The choice would depend on the investor's financial situation and preferences.

To remove the single quotation marks ('') at the beginning and end of a string and remove the item at index 12, you can use Python's string manipulation methods and list slicing. First, you can use the strip() method to remove the surrounding single quotation marks. Then, you can convert the string into a list using the list() function, remove the item at index 12 using list slicing, and finally convert the list back into a string using the join() method.

To remove the single quotation marks at the beginning and end of a string, you can use the strip() method. This method removes any leading and trailing characters specified in the argument. In this case, you can pass the single quotation mark ('') as the argument to strip().

Here's an example:

string = "'example string'"

stripped_string = string.strip("'")

After executing this code, the value of stripped_string will be 'example string' without the surrounding single quotation marks.

To remove the item at index 12 from the string, you need to convert it into a list. You can use the list() function for this conversion. Then, you can use list slicing to remove the item at index 12 by excluding it from the list. Finally, you can convert the modified list back into a string using the join() method.

Here's an example:

string_list = list(stripped_string)

string_list.pop(12)

result_string = ''.join(string_list)

After executing this code, the value of result_string will be the modified string with the item at index 12 removed.

Answer:

14n-3

Step-by-step explanation:

When a polynomial is to be divided by a linear expression and the leading coefficient (first number) must be a 1, synthetic division is used. Any polynomial equation, regardless of degree, can, for instance, be divided by x + 1, but not by x2+1.

Additionally, the binomial must be of degree 1; synthetic division cannot be used to divide by a binomial such as x2 + 1. Here are the steps for performing synthetic division on a polynomial by a binomial.

To get the quotient and the remainder, write down the coefficients and divide them by the linear factor's zero. Q(x) + (R/(x - a)) = (P(x)/(x - a)).

Answer:

8 boards.

Step-by-step explanation:

Since he bought a few of each length. The only combination that works is when he bought 5 of the 4 ft long board so 4×5=20. Than he bought 3 of the 5ft boards 3×5=15. 20+15=35 ft worth of boards.

Matt brought total 8 boards out of which the 5 boards are of 4ft and 3 boards are of 5ft.

We have a guy named Matt who bought some boards to build a wooden deck. Some of the boards were 4 ft long and some of the boards were 5 ft long. He bought 35 ft of boards altogether.

We have to find out how many boards he bought all together.

The solution of an equation is the value at which the left hand side and right hand side of the equation equals to each other.

In the question, it is given that there are 4ft long and 5ft long boards and matt brought 35 ft of board all together.

Let us assume that the number of 4 ft boards he bought are = x and the number of 5ft boards be y, then according to question -

4x + 5y = 35

\(y = \frac{-4x + 35}{5} \\y=\frac{-4x}{5} + 7\)

Now, all the points that lie on this line are the possible answers but the number of boards cannot be in decimal. Hence, the solution x = 5 and y=3, which will give us 4 x 5 + 5 x 3 which is equal to 35.

Hence, Matt brought 5 boards of 4ft and 3 boards of 5ft.

The amount of time at each of the two speeds are 5 hours at 59mph and 3 hours at 53mph

Time: Time is change, or the interval over which change occurs. It is impossible to know that time has passed unless something changes. The amount of time or change is calibrated by comparison with a standard. The SI unit for time is the second, abbreviated s

on the first part of a 454-mile trip, a salesperson averaged 59 miles per hour.

the salesperson averaged only 53 miles per hour on the last part of the trip because of an increased volume of traffic.

the total time of the trip was 8 hours.

let time travel t=59

(8-t)=53

distance=speed*time

distance at 59+distance at 53 =454

59t+53(8-t)=454

In the given question,

An electrician needs 1/2 of a roll of electrical wire to wire each room in a house.

We have to find the how many rooms he can wire with 8 1/2 rolls of wire.

We can wire one rooms by 1/2 of a roll.

We have total rolls = 8 1/2

Firstly we simplifying the 8 1/2

We can simplify 8 1/2 by multiplying 8 with 2 and then add the result of multiplication 8 and 2 with 1. Then we represent the result answer as numerator and in denominator have 2.

There is another way to solve the 8 1/2.

We can write 8 1/2 as 8+1/2

Then \(=8\times\frac{2}{2}+\frac{1}{2}\)

\(=\frac{16}{2}+\frac{1}{2}\)

\(=\frac{16+1}{2}\)

\(=\frac{17}{2}\)

Hence, 8 1/2 = 17/2

So we have total of wire 17/2.

In one room we need = 1/2

So the total number of room that can wire with 17/2 is

\(=\frac{17/2}{1/2}\)

We can write it as

= 17/2 × 2

= 17

-5 5/6

Step-by-step explanation:

convert 2/3 into 4/6 and when u subtract a positive from a negative u add it instead  

The provided function's definite integral from 0 to 10 is closest to 4.

The area of each zone that the function, the x-axis, and the two vertical lines at x = 0 and x = 10 bounds is added to form the definite integral of the function. The definite integral that results from adding up each of these areas is the one that is closest to 4. The area of the region above the x-axis is larger than the area of the region below the x-axis, which explains this. The area of the region above the x-axis is higher than the area below the x-axis because the function is rising across the interval. The overall area is closer to 4 since the area of the region below the x-axis is negative. As a result, 4 is the closest value for the definite integral of the 0–10 function.

Based on the context of the problem, the range of the exponential function y = \(45,529(0.78)^x\) is y > 0.

The exponential function for depreciation given in the problem is:

y = 45,529(0.78)^x

This function gives us the value of Sharlene's truck in dollars after x months of ownership, assuming that the depreciation follows a constant rate and is modeled by an exponential function.

To find the range of the function, we need to consider the minimum value that y can take. Since depreciation leads to a decrease in value over time, y should always be greater than zero. In other words, the range of the function is:

y > 0

In practical terms, this means that Sharlene's truck will always have some positive value, even if its market value has decreased due to depreciation. In other words, a truck is never worth zero or less than zero (unless it has additional debts associated with it), and Sharlene's truck will always have some resale or scrap value even if it has depreciated significantly.
