The statement that describes the behavior of the function f(x) is: The graph approaches 0 as x approaches infinity.

The correct answer is an option (b)

Consider the function [tex]f(x) = \frac{2x}{1-x^2}[/tex]

Consider the limit of function f(x) as x approaches infinity (x → ∞)

[tex]\lim_{n \to \infty} f(x)\\\\= \lim_{n \to \infty} \frac{2x}{1-x^2} \\\\= \lim_{n \to \infty} \frac{2x/x}{(1-x^2)/x}\\\\ = \lim_{n \to \infty} \frac{-2}{x}[/tex]

= 0

This means that when x approaches infinity the term x² grows rapidly

So, 1 - x², which is in the denominator will decrease, become a large negative more rapid than the x in the numerator.

We can say that the function approaches zero.

Thus the correct statement is: The graph approaches 0 as x approaches infinity.

If the daily prices are $ 1.50 for children and $ 2.25 for adults, a total of 284 children and 255 adults swam at the public pool that day.

Let's assume that the number of children who swam in the pool is x, and the number of adults who swam in the pool is y.

From the problem statement, we know that the total number of people who swam in the pool is 539. Therefore, we can write:

x + y = 539

We also know that the total receipts for admission are $1017.00. The price for a child is $1.50 and the price for an adult is $2.25. Therefore, the total revenue can be expressed as:

1.5x + 2.25y = 1017

Now we have two equations with two variables. We can solve for x and y by using any method of solving linear equations. For example, we can use the substitution method to solve for x and y:

x + y = 539 → x = 539 - y

Substituting this value of x into the second equation, we get:

1.5(539 - y) + 2.25y = 1017

Simplifying and solving for y, we get:

y = 255

Substituting this value of y into the equation x + y = 539, we get:

x = 539 - 255 = 284

Answer:

1) 35%

2) 73%

3) 23%

4) 57%

5) 13%

6) 37%

Step-by-step explanation:

The general solution is to grab the total, which is 100%, and subtract the percentage of the given problems to find the solution. In some problems you have to add some percentages togheder to finish the problem.

So, in the first problem you subtract the percentage of girls to the whole class percentage: 100%-65%=35%.

In the second, whole package minus the red ones: 100%-27%= 73%

In the third, group of children minus swimmers: 100%-78%=22%

In the fourth, 100%-43%= 57%.

In the fifth, there is won percentage, loss percentage, and the remaining percentage you need to add to make 100% is the tie percentage.

So if we do the reverse (subtracting both win and loss percentage to have the tie percentage): 100%-45%-42%=13%.

In the sixth, it's the same thing as the fifth problem: subtracting the basketball and hockey from the whole children percentage that chose the sport: 100%-35%-28%=37%.

Let's use the variable "x" to represent the number of 3-inch bolts that James bought.

We know that he bought a total of 16 bolts, so the number of 4-inch bolts he bought would be 16 - x.

The cost of the 3-inch bolts is 36 cents each, so the total cost of the 3-inch bolts would be 0.36x dollars.

Similarly, the cost of the 4-inch bolts is 42 cents each, so the total cost of the 4-inch bolts would be 0.42(16 - x) dollars.

We know that the total cost of all the bolts was $6.00, so we can set up the following equation:

0.36x + 0.42(16 - x) = 6.00

Simplifying and solving for x, we get:

0.36x + 6.72 - 0.42x = 6.00

-0.06x = -0.72

x = 12

Therefore, James bought 12 of the 3-inch bolts.

Answer:

  √(205)/13

Step-by-step explanation:

You want sec(θ) when cot(θ) = 13/6.

Some calculators can figure this directly as ...

  [tex]\sec{(\cot^{-1}\dfrac{13}{6})}=\boxed{\dfrac{\sqrt{205}}{13}}[/tex]

Others need to make use of the trig relations ...

  tan(θ) = 1/cot(θ)

  sec(θ) = √(tan²(θ) +1)

or

  sec(θ) = 1/cos(θ)

The tangent of the angle is

  tan(θ) = 1/cot(θ) = 1/(13/6) = 6/13.

Then the secant is ...

  sec(θ) = √((6/13)² +1) = √(6² +13²)/13

  sec(θ) = √205/13

A calculator can get there from ...

  sec(θ) = 1/cos(arctan(6/13)) = √205/13

Angle or arc HGJ is measured at 275 for given figure.

Arcs may be created from the circumference of a circle. It is referred to as the curved line that connects two locations on a circle's perimeter and splits it into segments. The length of an arc is inversely proportional to the angle it makes at the centre of the circle.

When the central angle rises, so does the arc's length, and vice versa. Arcs are commonly used to depict and compute measurements of circles and circular objects in geometry, trigonometry, and physics.

For given problem,

mHGJ= 360° - mJH = 360°-( mJl + mlH ) =  360°-(30°+55°)

         = 360°-85° = 275°

Answer:

Alex's gross pay for the month is $18/hour x 140 hours = $2520.

The total deductions from his paycheck are:

$180.00 (FICA) + $215.00 (Federal income tax) + $62.00 (State income tax) + $72.89 (Health insurance) + $50.00 (Retirement savings) = $579.89

So Alex's net pay (take-home pay) is:

$2520 (gross pay) - $579.89 (deductions) = $1940.11

To find the percentage of his gross pay that he took home, we can divide his net pay by his gross pay and multiply by 100:

($1940.11 / $2520) x 100 = 77.06%

Therefore, Alex took home 77.06% of his gross pay after deductions.

This polynomial cannot be factored any further using integer coefficients, so our final factored form is: 40w²11 + 16w²6 = 8w²6(5w²5 + 2)

How to solve?

To factor the polynomial 40w²11 + 16w²6, we need to look for common factors in the two terms. We notice that both terms have a factor of 8w²6, so we can factor that out:

40w²11 + 16w²6 = 8w²6(5w²5 + 2)

Now, we have factored out the greatest common factor of the two terms, leaving us with the remaining factor of 5w²5 + 2. This polynomial cannot be factored any further using integer coefficients, so our final factored form is:

40w²11 + 16w²6 = 8w²6(5w²5 + 2)

If the normally distributed heights have mean as 69, then the probability that he can fit through the doorway without bending is 0.9938.

In "Normal-Distribution", probability refers to the likelihood of a continuous random variable falling within a certain range of values

We first convert the height of the doorway and the height of the male passenger to z-scores by using z = (x - μ) / σ,

where:

x = height (doorway height or male passenger height)

μ = mean of the male height,

σ = standard deviation of male height,

For the doorway height:

⇒ [tex]Z_{doorway}[/tex] = (76 - 69.0)/2.8 = 2.50,

For a male passenger:

⇒ [tex]Z_{male}[/tex] = (x - 69.0)/2.8,

To find the probability that a randomly selected male passenger can fit through the doorway without bending, we need to find the proportion of the "male-population" that has a height less than or equal to the height of the doorway;

⇒ P([tex]Z_{male}[/tex]  ≤  [tex]Z_{doorway}[/tex] ) = P([tex]Z_{male}[/tex]  ≤ 2.50) and

We know that the value of P(z ≤ 2.50) is 0.9938,

i) The after-tax operating cash flows that will be remitted to the parent company each year are USD 73.53, 110.30 and USD 146.34.

ii) The Net Present Value of the project are USD 66.85, USD 91.90 and USD 107.50.

iii) The MNC may want to consider other investment opportunities or reassess the assumptions used in this analysis.

iv) As per the subsidiary, the firm may be better off remitting earnings on a regular basis to minimize exchange rate risk and invest in a diversified portfolio of assets to mitigate other types of risks.

i) To calculate the after-tax operating cash flows that will be remitted to the parent company each year, we need to first calculate the operating cash flows in CAD and then convert them to USD while taking into account the tax on remitted funds. Let's assume the operating cash flows for each year are CAD 100, CAD 150, and CAD 200, respectively.

In year 1, the CAD 100 operating cash flow is remitted to the parent company in USD. Using the exchange rate of C$1.02 per US$, this is equal to USD 98.04. However, the MNC must pay a 25% tax on this amount, so the after-tax cash flow is USD 73.53.

In year 2, the CAD 150 operating cash flow is remitted to the parent company in USD. Using the same exchange rate of C$1.02 per US$, this is equal to USD 147.06. After the 25% tax on remitted funds, the after-tax cash flow is USD 110.30.

In year 3, the CAD 200 operating cash flow is remitted to the parent company in USD. However, the exchange rate has changed to C$1.025 per US$, so the CAD 200 is now equal to USD 195.12. After the 25% tax on remitted funds, the after-tax cash flow is USD 146.34.

Therefore, the after-tax operating cash flows that will be remitted to the parent company each year are USD 73.53, USD 110.30, and USD 146.34, respectively.

ii) To calculate the Net Present Value (NPV) of the project, we need to discount the after-tax operating cash flows back to their present value using a discount rate that reflects the riskiness of the project. Let's assume a discount rate of 10%. Using this rate, we can calculate the present value of each year's after-tax cash flow as follows:

Year 1: USD 73.53 / (1 + 0.10)¹ = USD 66.85

Year 2: USD 110.30 / (1 + 0.10)² = USD 91.90

Year 3: USD 146.34 / (1 + 0.10)³ = USD 107.50

iii) Based on the calculated NPV, the MNC should not accept the project. The negative NPV indicates that the project is not expected to create value for the MNC's investors. Additionally, the after-tax operating cash flows that will be remitted to the parent company each year are not sufficient to compensate for the investment's costs and the 25% tax on remitted funds.

iv) The drawback of Flagstaff Corp.'s approach of reinvesting earnings in Mexican government securities for 10 years before remitting accumulated earnings to the United States is that it exposes the firm to exchange rate risk.

Answer:

Step-by-step explanation:

To solve this problem, we need to use the distance formula to find the length of each side of the triangle, and then apply the Pythagorean theorem to determine whether the triangle is a right triangle.

Let's label the three vertices of the triangle as A, B, and C, and their coordinates as follows:

A = (-2, 5)

B = (3, -1)

C = (1, 3)

The length of AB is:

AB = sqrt((3 - (-2))^2 + (-1 - 5)^2) = sqrt(25 + 36) = sqrt(61)

The length of AC is:

AC = sqrt((1 - (-2))^2 + (3 - 5)^2) = sqrt(9 + 4) = sqrt(13)

The length of BC is:

BC = sqrt((1 - 3)^2 + (3 - (-1))^2) = sqrt(4 + 16) = sqrt(20) = 2sqrt(5)

Now, we need to check whether the triangle is a right triangle. We can do this by checking whether the sum of the squares of the two shorter sides (AB and AC) is equal to the square of the longest side (BC). If it is, then the triangle is a right triangle.

AB^2 + AC^2 = 61 + 13 = 74

BC^2 = (2sqrt(5))^2 = 20

Since AB^2 + AC^2 is not equal to BC^2, the triangle is not a right triangle.

Therefore, the answer is: "The triangle is not a right triangle."

The missing dimensions of the triangular plot of land are:

i. b = 2.45

ii. A = 69.5

iii. C = 75.5^o

A cosine rule is a trigonometric function that can be used to determine the length of side, or measure of the internal angles of a none right angled triangle.

Cosine rule states that;

[tex]b^{2}[/tex] = [tex]a^{2}[/tex] + [tex]c^{2}[/tex] -2acCos B

To determine the missing values of the triangle in the attached diagram, we have;

[tex]b^{2}[/tex] = [tex]a^{2}[/tex] + [tex]c^{2}[/tex] -2acCos B

  = 4^2 + 7^2 - 2(4*7)Cos35^o

  = 16 + 49 -2(36*0.8192)

  = 65 - 58.9824

  = 6.0176

b = (6.0176)^1/2

  = 2.4531

b = 2.45

From sine rule,

a/ Sin A = b/Sin B = c/ Sin C

a/ Sin A = b/Sin B

4/Sin A = 2.45/ Sin 35

Sin A = 4* Sin 35/ 2.45

        = 0.9365

A = Sin^-1 0.9365

  = 69.47

A = 69.5

So to determine the value of C, we have;

A + B + C = 180^o

69.5 + 35 + C = 180

104.5 + C = 180

C = 180 - 104.5
