The price of 5 citrons and 3 fragrant wood apples is 27 units. The price of 3 citrons and 5 fragrant wood apples is 29 units. Find the price of a citron and the price of a wood apple.
The Solution.
Let the price of a citron be represented with x, and the price of a fragrant wood apple be y.
So, the first sentence in the question gives the equation below:
\(5x+3y=27\ldots eqn(1)\)Similarly, the second sentence in the question gives the equation below:
\(3x+5y=29\ldots eqn(2)\)Solving the above pair of equations simultaneously using the Elimination Method:
We shall eliminate the term in x;
So, we shall multiply through eqn(1) by 3, we get
\(\begin{gathered} 3(5x+3y=27) \\ 15x+9y=81\ldots eqn(3) \end{gathered}\)Similarly, we shall multiply through eqn(2) by 5, we get
\(\begin{gathered} 5(3x+5y=29) \\ 15x+25y=145\ldots eqn(4) \end{gathered}\)Subtracting eqn(3) from eqn(4), we have
\(\begin{gathered} 15x+25y=145 \\ -(15x+9y=81) \end{gathered}\)We get:
\(16y=64\)Dividing both sides by 16, we get
\(\begin{gathered} \frac{16y}{16}=\frac{64}{16} \\ \\ y=4 \end{gathered}\)To find x, we shall substitute 4 for y in eqn(1):
\(\begin{gathered} 5x+3(4)=27 \\ 5x+12=27 \end{gathered}\)Collecting the like terms, we get
\(\begin{gathered} 5x=27-12 \\ 5x=15 \end{gathered}\)Dividing both sides by 5, we get
\(\begin{gathered} \frac{5x}{5}=\frac{15}{5} \\ \\ x=3 \end{gathered}\)Therefore, the price of a citron is 3 units, and the price of a fragrant wood apple is 4 units.

2 two angles are supplementary. The
measure of one angle is 9 times the
measure of the other angle. What is the measure of the smaller angle
Answer:
18 degrees heres youre answer!
Step-by-step explanation:
If Angle 1 is x, and Angle 2 is 9x (because one angle is 9 times as large as the other), then x + 9x = 180. Add like terms: 10x = 180. solve for x by dividing both sides by 10. Therefore, x = 18 degrees = smaller angle.

Answer:
Step-by-step explanation:
The tangent of the angle can be found using the identity for the tangent of the difference of angles.
tan(α-β) = (tan(α) -tan(β))/(1 +tan(α)tan(β))
The tangent of the angle of each vector is the ratio of the j coefficient to the i coefficient.
tan(α) = -2/3
tan(β) = 4/7
tan(α-β) = (-2/3 -4/7)/(1 +(-2/3)(4/7))
= (-14-12)/(21 -8) = -26/13 = -2

And we need to find the sum of series by using the Maclaurin series as
Now, the sum of series is calculated as,
=>f(n) = \(\sum\frac{(-1)^n\pi^{2n}}{4^{2n}(2n)!}\)
When we put the value on n = 0, then we get,
=> f(0) = [1 x 3.14]/1] = 3.14
Now, we have to put the value of the function, the value of x as 1,
Then we get,
=> f(1) = [-1 x 9.8596] / [16 x 2]
=> f(1) = -0.308
And then we have to put the value of function for the value of x as 2,
Then we get,
=> f(2) = [1 x 30.959] / [64 x 24]
=> f(2) = 0.0201

You are starting a family pizza parlor and need to buy a motorcycle for delivery orders. You have two models in mind. Model A costs $8,600 and is expected to run for 6 years; Model B is more expensive, with a price of $15,100, and has an expected life of 10 years. The annual maintenance costs are $840 for Model A and $690 for Model B. Assume that the opportunity cost of capital is 10 percent. Calculate equivalent annual costs (EAC) of each models. (Do not round the discount factor. Round intermediate calculations and final answers to 2 decimal places, e.g. 15.25.)
The equivalent annual cost (EAC) of Model A is $2,332.60, while the EAC of Model B is $2,094.81. The EAC represents the annual cost of owning and operating the motorcycle over its expected life, taking into account the initial cost, annual maintenance costs, and the opportunity cost of capital.
To calculate the EAC, we use the formula:
EAC = (C + (M × A)) × D
Where:
C = Initial cost
M = Annual maintenance cost
A = Annuity factor
D = Discount factor
For Model A, the initial cost is $8,600 and the annual maintenance cost is $840. The expected life of the motorcycle is 6 years, so the annuity factor is calculated as follows: A = (1 - (1 + r)^(-n)) / r, where r is the discount rate (10% or 0.10) and n is the number of years (6). The annuity factor for Model A is 4.1119. The discount factor is calculated as (1 + r)^(-n), which is 0.5645. Plugging these values into the formula, we get EAC = ($8,600 + ($840 × 4.1119)) × 0.5645 = $2,332.60.
For Model B, the initial cost is $15,100 and the annual maintenance cost is $690. The expected life of the motorcycle is 10 years, so the annuity factor is calculated as A = (1 - (1 + r)^(-n)) / r, where r is 0.10 and n is 10. The annuity factor for Model B is 7.6068. The discount factor is calculated as (1 + r)^(-n), which is 0.3855. Plugging these values into the formula, we get EAC = ($15,100 + ($690 × 7.6068)) × 0.3855 = $2,094.81.
Therefore, the equivalent annual cost for Model A is $2,332.60 and for Model B is $2,094.81. Based on these calculations, Model B has a lower EAC and would be the more cost-effective choice for the family pizza parlor in terms of annual costs.

Give an ϵ/N proof that limn→[infinity](√n+2−√n)=0
The given statement " limn→infinity=0 using an ϵ/N " is true and proved by showing that for any given ϵ > 0, there exists an N such that if n > N, then |√n+2−√n| < ϵ.
Let ϵ > 0 be given. We want to find an N such that |√n+2−√n| < ϵ for n > N.
First, we can simplify |√n+2−√n| as follows:
|√n+2−√n| = |(√n+2−√n) * (√n+2+√n) / (√n+2+√n)| = |(n+2−n) / (√n+2+√n)| = 2 / (√n+2+√n)
Now, we need to find an N such that 2 / (√n+2+√n) < ϵ for n > N. Multiplying both sides by (√n+2−√n), we get:
2 < ϵ(√n+2+√n)
2/ϵ < √n+2+√n
Squaring both sides, we get:
4/ϵ^2 < n+2+2√n(n+2)+n
4/ϵ^2 < 2n+2√n(n+2)
n > (4/ϵ^2 - 2)/(2√n+2)
Since we want n > N, we can choose N to be any integer greater than or equal to (4/ϵ^2 - 2)/(2√N+2). Then, for any n > N, we have:
n > (4/ϵ^2 - 2)/(2√n+2)
2 / (√n+2+√n) < ϵ
|√n+2−√n| < ϵ
This completes the proof.

Which of the following is a way that the liability of foreignness manifests?
a. Reduction of language barriers
b. Similarities of formal and informal institutions
c. Adoption of VIRO
d. Discrimination against foreign firms
The correct answer is option (d). Discrimination against foreign firms.
The liability of foreignness refers to the challenges and disadvantages that foreign firms face when operating in a new country or market. These challenges can manifest in a variety of ways, including cultural differences, legal and regulatory barriers, and discrimination against foreign firms.
Discrimination against foreign firms is a common way that the liability of foreignness manifests. This can include discriminatory policies or practices that make it difficult for foreign firms to compete with domestic firms. For example, a government may impose higher taxes or tariffs on foreign firms, or require foreign firms to meet stricter regulatory requirements than domestic firms. Discrimination can also come in the form of cultural bias or prejudice against foreign firms, which may make it difficult for them to establish relationships with local customers and partners.
In contrast, the other answer choices are not ways that the liability of foreignness manifests. Reduction of language barriers and similarities of formal and informal institutions may actually reduce the liability of foreignness, while adoption of VIRO (Valuable, Rare, Inimitable, and Organized) is a framework for analyzing a firm's competitive advantage and is not directly related to the liability of foreignness.
