45 billion Korean Won is equal to 45 million US Dollars.

The formula for  (USD) is USD = KRW / 1000. To calculate 45 billion won in USD, we must first convert KRW to USD. 45 billion KRW is equal to 45,000,000,000 KRW. Using the formula above, we can calculate the amount of USD:

USD = 45,000,000,000 KRW / 1000

USD = 45,000,000 USD

Therefore, 45 billion won is equal to 45 million US Dollars.

To better understand this conversion, it is important to remember that one US Dollar is equal to 1000 Korean Won. As an example, if you have 10,000 Korean Won, you can convert that to USD by dividing 10,000 by 1000, which equals 10 USD. The same concept applies when converting larger numbers. To convert 45 billion KRW to USD, we must divide 45,000,000,000 by 1000, which equals 45,000,000 USD.

In conclusion, 45 billion Korean Won is equal to 45 million US Dollars.

Step-by-step explanation:

\(R_2\)  is 3 ohms

In a circuit containing two resistors \(R_1\) and \(R_2\) connected together in parallel, the total resistance \(R_T\) is given by;

\(\frac{1}{R_T} = \frac{1}{R_1} + \frac{1}{R_2}\)              ---------(i)

Make \(R_2\) subject of the formula;

=> \(\frac{1}{R_2} = \frac{1}{R_T} - \frac{1}{R_1}\)  

=> \(\frac{1}{R_2} = \frac{R_1 - R_T}{R_TR_1}\)

=>   \({R_2} = \frac{R_TR_1}{R_1 - R_T}\)       ---------------(ii)

From the question,

\(R_1\) = 6Ω

\(R_T\) = 2Ω

Substitute these values into equation (ii) as follows;

=> \({R_2} = \frac{2*6}{6 - 2}\)

\({R_2} = \frac{12}{4}\)

\(R_2\) = 3Ω

Therefore, the value of \(R_2\) = 3 ohms or \(R_2\) = 3Ω

Answer: is 3 ohms.

The square's diagonal length is (E) d = 11√2.

A diagonal is a line segment that connects two vertices (or corners) of a polygon also, connects two non-adjacent vertices of a polygon.

This connects the vertices of a polygon, excluding the figure's edges.

A diagonal can be defined as something with slanted lines or a line connecting one corner to the corner farthest away.

A diagonal is a line that connects the bottom left corner of a square to the top right corner.

So, we need to determine the length of the square's diagonal.

The formula for the diagonal of a square is; d = a2; where 'd' is the diagonal and 'a' is the side of the square.

Now, d = 11√2.

Hence, the square's diagonal length is (E) d = 11√2.

Answer:

Step-by-step explanation:

"the product of 2 and a number": 2n

Answer:

7 - (2+3) = 2

Step-by-step explanation:

please correct me if this is wrong.

The radius of convergence, r, can be found using the ratio test:
lim┬[n→∞]⁡|n^2*x^(n+1)*2*4*6*...*(2n)/(n^2*x^n*2*4*6*...*(2n-2))| = lim┬[n→∞]⁡|x*(2n+2)/(2n+1)| = |x|

Since the limit exists only when |x| < 1, the radius of convergence is 1.
To find the interval of convergence, we need to test the endpoints of the interval [−1,1].
For x = −1, the series becomes:
∑(−1)^n*(2n)*(2*4*6*...*(2n))/n^2 = ∞
This series diverges.
For x = 1, the series becomes:
∑(2n)*(2*4*6*...*(2n))/n^2 = ∞
This series also diverges.
Therefore, the interval of convergence is (−1,1).
The given series is Σ(n²xⁿ)/(2n) where n goes from 1 to infinity. To find the radius of convergence, r, we use the ratio test. Consider the absolute value of the ratio aₙ₊₁/aₙ:
| [(n+1)²x^(n+1)]/(2(n+1)) ] / [ (n²xⁿ)/(2n) ] |
Simplify and cancel terms:
| (n+1)²/n² | * | x |
As n approaches infinity, the limit of (n+1)²/n² is 1. Thus, we have:
lim (n -> ∞) | (n+1)²/n² | * | x | = | x |
For convergence, the limit should be less than 1:
| x | < 1
Therefore, the radius of convergence, r, is 1, and the interval of convergence, i, is (-1, 1).

Answer:

n = (W - Z)/a

Step-by-step explanation:

W = an + Z

Rearrange the equation so that the subject is alone, in the format Ax = B

W = an + Z

W - Z = an + Z - Z

W - Z = an

Isolate the subject by dividing or multiple so that the equation is in the format x = C

W - Z = an

(W - Z)/a = an/a

(W - Z)/a = n

At the optimal level where the present worth of cost is $3 million, the B/C ratio is 0 that is present worth of cost that optimizes the benefit/cost ratio.

To find the present worth of cost that optimizes the benefit/cost ratio, we need to solve the given equation:

(PW of benefits)² - 18 * (PW of cost) + 54 = 0

Let's solve this equation to find the present worth of cost.

By rearranging the equation, we have:

(PW of benefits)² = 18 * (PW of cost) - 54

Taking the square root of both sides, we get:

PW of benefits = √(18 * (PW of cost) - 54)

To optimize the benefit/cost ratio, we want to find the value of PW of cost that minimizes the denominator. In this case, we can consider the derivative of the benefit/cost ratio with respect to the PW of cost and set it equal to zero to find the minimum value. Taking the derivative of the benefit/cost ratio with respect to the PW of cost, we get:

d(B/C) / d(PW of cost) = -18 / (PW of benefits)

= -18 / √(18 * (PW of cost) - 54)

Setting the derivative equal to zero, we have:

-18 / √(18 * (PW of cost) - 54) = 0

Solving this equation, we find that PW of cost = $3 million.

Therefore, the present worth of cost for the project that optimizes the benefit/cost ratio is $3 million. To calculate the B/C ratio at the optimal level, we substitute the value of PW of cost into the equation:

(PW of benefits)² - 18 * (PW of cost) + 54 = 0

(PW of benefits)² - 18 * 3 + 54 = 0

(PW of benefits)² = 0

PW of benefits = 0

(x1,y1) and (x2,y2)

========================================================

Reason:

Each point is of the form (x,y) where x is first. Think of the ordering of the letters in the alphabet.

Then we stick 1's or 2's to each point to help distinguish the points from one another.

Writing (x1,y1) is the same as saying \((\text{x}_1, \text{y}_1)\), and similarly (x2,y2) is the same as \((\text{x}_2, \text{y}_2)\). We cannot mix up the 1's and 2's. They must remain separate.

This notation is helpful for the distance formula, midpoint formula, and also the slope formula. There are likely other useful applications as well.

It is important for the bank analyst to acknowledge the limitations of a convenience sample and consider alternative methods of sampling to obtain a more accurate representation of the customers' home-buying experiences.

A bank analyst wants to ask customers who have a mortgage with the bank about the customers' home-buying experiences. A convenience sample of customers would be a group of individuals who are easily accessible and readily available to participate in the study. This could be customers who are physically present in a bank branch at a given time or customers who have recently interacted with the bank through phone or online channels. However, this method of sampling may not be representative of the entire population of customers who have a mortgage with the bank, as it may exclude certain groups of customers who do not frequently interact with the bank or have unique circumstances. Therefore, it is important for the bank analyst to acknowledge the limitations of a convenience sample and consider alternative methods of sampling to obtain a more accurate representation of the customers' home-buying experiences.

Complete question is:

For the function, find the points on the graph at which the tangent line is horizontal. If none exist, state that fact.

y = ¹/₃x³ - 2x + 3

To find the points on the graph at which the tangent line is horizontal, we need to find the x-values where the derivative of the function is equal to zero.

To find the points on the graph at which the tangent line is horizontal, we need to find the x-values where the derivative of the function is equal to zero. The derivative represents the rate of change or slope of the function at any given point.

Let's say we have a function f(x). To find the derivative of f(x), we differentiate the function with respect to x. The resulting derivative function is denoted as f'(x) or dy/dx.

Next, we set the derivative function f'(x) equal to zero and solve for x. The x-values obtained from this equation represent the points on the graph where the tangent line is horizontal.

If there are no solutions to the equation f'(x) = 0, it means there are no points on the graph where the tangent line is horizontal.

Answer:

A. slope of f(x) is 3

B. g(x) has greater y-intercept

Step-by-step explanation:

A.slope of f(x): m = (y2-y1)/(x2-x1)

m = (3 - 0)/(1 - 0) = 3/1 = 3

then y = mx + b => y = 3x + b

then substituting (1,3) => 3 = 3(1) + b => 3 = 3 + b => b = 0

so y = 3x

slope of f(x) is 3

using  y = mx + b

then g(x) = 7x + 2 => slope of g(x) is 7

B. b is the y-intercept

so for f(x) = 3x => b is 0

and for g(x) = 7x + 2 => b is 2

so g(x)'s y-intercept is 2 which is great than f(x)'s

If Priya had half the money she has now, she would have less than $20, which means she currently has somewhere between $20 and $40.

Based on the given information, we know that Priya currently has more than $40, because if she had half that amount ($20), she would have less than $20. This means that we can set up an inequality to represent the situation:

0.5x < 20

where x represents the amount of money that Priya currently has.

To solve for x, we can multiply both sides of the inequality by 2:

x < 40

This means that the maximum amount of money that Priya currently has is $40. However, we don't know the exact amount she has, only that it's somewhere between $20 and $40.

In summary, if Priya had half the money she has now, she would have less than $20, which means she currently has somewhere between $20 and $40. We can represent this information with the inequality 20 < x < 40, where x represents the amount of money Priya currently has.

Find the slope of the perpendicular line

When two lines are perpendicular, the product of their slopes is -1. This means that the slopes are negative-reciprocals of each other.

                 ⇒  if the slope of this line = 2     (y = 2x + 2)

                      then the slope of the perpendicular line (m) = - ¹/₂

Determine the equation

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:  

                               ⇒  y - 3 =  - ¹/₂  (x - 4)

We can also write the equation in the slope-intercept form by making y the subject of the equation and expanding the bracket to simplify:

                             since   y - 3 =  - ¹/₂  (x - 4)

                                              y = - ¹/₂ x + 5   (in slope-intercept form)

In 63 mailboxes, the postman put all the newspapers and magazines.

To solve this problem, we need to find the total number of newspapers and magazines that the postman delivered and divide that by 3 to get the number of mailboxes.

The total number of press releases is the sum of the number of newspapers and the number of magazines, multiplied by 3 (since the postman placed 3 press releases for each subscriber):

Total number of press releases = (35 + 28) * 3 = 189

To find the number of mailboxes, we divide the total number of press releases by 3:

Number of mailboxes = 189 / 3 = 63

Therefore, the postman put all the newspapers and magazines in 63 mailboxes.
