Answer:
x = -13/7, y = 54/7
Step-by-step explanation:
- Set equations equal to each other
[tex]5x + 17 = -2x +4[/tex]
Add 2x to both sides
[tex]7x +17 = 4[/tex]
Subtract 17 from both sides
[tex]7x = -13[/tex]
divide both sides by 7
[tex]x = -13/7[/tex]
Then substitute x into one of the equations. I picked the first one.
[tex]y = 5 (-13/7) + 17[/tex]
I multiplied 5 by -13 to get -65/7. Then I turned 17 into sevenths: 17 x 7 = 119, so that's 119/7. 119 + -65 = 54, so 54/7 for y.

Construct the first three Fourier approximations to the square wave function f(x) = {1 - pi lessthanorequalto x < 0 -1 0 lessthanorequalto x < pi F_1(x) = -(4/pi)*(sin(x)) F_2(x) = (4/pi)*(sin(x)) F_3(x) = (4/pi)*((sin(x))-(1/3)*(sin(3x)))
The Fourier series for f(x) is f(x) = (4/π) [sin(x) + (1/3) sin(3x) + (1/5) sin(5x) + ...].
The square wave function can be defined as:
f(x) = {1 -π ≤ x < 0
-1 0 ≤ x < π
To find the Fourier series for this function, we first need to determine the coefficients a_n and b_n.
a_n = (1/π) ∫_0^π f(x) cos(nx) dx
= (1/π) ∫_0^π (-1) cos(nx) dx + (1/π) ∫_(-π)^0 cos(nx) dx
= (2/π) ∫_0^π cos(nx) dx
= (2/π) [sin(nπ) - sin(0)]
= 0
b_n = (1/π) ∫_0^π f(x) sin(nx) dx
= (1/π) ∫_0^π (-1) sin(nx) dx + (1/π) ∫_(-π)^0 sin(nx) dx
= -(2/π) ∫_0^π sin(nx) dx
= -(2/π) [cos(nπ) - cos(0)]
= (2/π) [1 - (-1)^n]
Therefore, the Fourier series for f(x) is:
f(x) = (4/π) [sin(x) + (1/3) sin(3x) + (1/5) sin(5x) + ...]
To find the first three Fourier approximations, we truncate this series at the third term.
F_1(x) = -(4/π) sin(x)
F_2(x) = (4/π) sin(x) + (4/3π) sin(3x)
F_3(x) = (4/π) sin(x) + (4/3π) sin(3x) - (4/5π) sin(5x)
These are the first three Fourier approximations of the square wave function f(x). The more terms we include in the Fourier series, the closer the approximations will be to the original function.

Given: Triangle ABC is similar to triangle DEF, side BC = 19, angle ABC = 48, angle BCA = 73.
If the side DF = 15, then AB - EF = ?
Answer:
We are given two similar triangles, triangle ABC and triangle DEF, and some measurements of triangle ABC. We are also given that DF, one of the sides of triangle DEF, is equal to 15 units. Using this information, we are asked to find the difference between the lengths of sides AB and EF.
To solve the problem, we can first use the angle-angle similarity theorem to determine that the corresponding angles of the two triangles are equal. Therefore, angle DEF is equal to angle BCA, and angle ABE is equal to angle DFE.
Next, we can use the law of sines to find the length of side AB. The law of sines states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is equal for all sides and angles in the triangle. Applying this to triangle ABC, we have:
AB/sin(73) = BC/sin(48)
Substituting the value of BC as 19 units, we can solve for AB to get:
AB = 22.78 units
Similarly, we can use the law of sines to find the length of side EF. Since angle DFE is equal to angle ABE, we can use the same ratio as above to get:
EF/sin(73) = DF/sin(48)
Substituting the value of DF as 15 units, we can solve for EF to get:
EF = 18.20 units
Finally, we can subtract EF from AB to get:
AB - EF = 22.78 - 18.20 = 4.58 units
Therefore, the difference between the lengths of sides AB and EF is 4.58 units.

If an excise tax is levied on the suppliers of tobacco, will the incidence fall mostly on consumers or mostly on producers? Will there be a large amount or small amount of deadweight loss? Will tax revenue from the tobacco tax fall or rise?
As the demand for tobacco is inelastic so the consumers are the group who are less responsive to a higher price as an outcome of it the consumers will have to bear the largest share of the tobacco tax.
This inelasticity of demand will lead to only a small decline in the quantity demanded after the tax have been leived , therefore the deadloss weight will be in really small degree. the percentage increase in price of any amount will overcome a smaller decline in the quantity which eventually would lead to a rise in the tax revenue collection.
Inelasticity of demand refers to the degree to which the quantity demanded of a particular good or service changes in response to a change in its price. When demand is inelastic, a change in price will result in a proportionally smaller change in quantity demanded. This is typically the case for goods or services that are considered necessities or have few substitutes available.
For example, if the price of insulin, a life-saving medication for diabetics, increases by 10%, it is unlikely that the quantity demanded will decrease by 10%. People with diabetes require insulin to manage their condition, and there are few substitutes available, so they are willing to pay a higher price to maintain their health.

What is exponential decay?A quantity declines over time proportionate to its existing value through a process known as exponential decay. An exponential function of the form f(t) = ab raised to t, where an is the beginning value, b is the decay factor (a number between 0 and 1), and t represents time, mathematically describes this.
Several real-world circumstances, like population increase, radioactive decay, and the loss of electrical charge in a capacitor, exhibit exponential decay.
Given that the situation follows a exponential decay model.
The exponential decay is given as:

a) Find the profit maximizing level of output (Q)
b) What price should you charge for your product?
c) Based on your answers in the previous two questions, how much profit is this firm making at the profit maximizing level of output?
The profit-maximizing output of 1.91, the firm is incurring a loss of $29.42.
a) Find the profit-maximizing level of output (Q)To determine the profit-maximizing level of output, we must calculate the marginal cost and marginal revenue of the firm.MC= dTC/dQ= -6Q^2-100+68Q=2(17Q^2-34Q-50)So, the marginal cost of the firm is MC= 2(17Q^2-34Q-50)To find the marginal revenue (MR) we must differentiate the revenue function with respect to Q.MR= dTR/dQ= P + Q(dP/dQ)= 20-4QHence, the marginal revenue is MR= 20-4QAt the point of maximum profit, marginal cost (MC) equals marginal revenue (MR).Therefore, 2(17Q^2-34Q-50)=20-4Q34Q^2-68Q-100=0Solving the above equation gives Q=1.91Therefore, the profit-maximizing output is 1.91 units.b) What price should you charge for your product?The price the firm should charge for its product is given by the demand function, P=20-2Q.Substituting Q=1.91 into the demand function,P= 20-2(1.91) = $16.18c) Based on your answers in the previous two questions, how much profit is this firm making at the profit-maximizing level of output?The total profit of the firm is given by the difference between the revenue and the total cost.TR= P x Q = 16.18 x 1.91 = $30.92TC= 100-2(1.91)^3-100(1.91)+34(1.91)^2 = $60.34Profit = TR- TC= $30.92-$60.34= -$29.42At the profit-maximizing output of 1.91, the firm is incurring a loss of $29.42.

assume a corporation has cumulative voting and there are two directors up for election. what is the maximum number of votes a shareholder who owns 100 shares can cast for candidate jones if there are a total of 5 candidates?
Assuming that a corporation has cumulative voting and two directors are up for election. The maximum number of votes a shareholder who owns 100 shares can cast for candidate Jones is 40.
What is cumulative voting?Cumulative voting is a voting method used by shareholders in a company to elect a board of directors.
In this type of voting, each shareholder is given the number of votes equal to the number of shares they own, multiplied by the number of candidates. This means that if there are two candidates and a shareholder has 100 shares, then they can cast up to 200 votes for each candidate.
How to calculate the maximum number of votes for candidate Jones?In this case, there are 5 candidates, and two directors are to be elected. Therefore, the total number of votes will be the sum of the votes required for each director, which will be 100.
The maximum number of votes that a shareholder with 100 shares can cast for each candidate will be equal to the total number of votes multiplied by the percentage of the vote that each candidate is allocated.
For example, if candidate Jones is allocated 20% of the votes, then the maximum number of votes that a shareholder with 100 shares can cast for candidate Jones will be:
Total number of votes = 2 x 100 = 200
Percentage of votes allocated to candidate Jones = 20%
Maximum number of votes for candidate Jones = 200 x 20/100 = 40.

Given that m∠A=(16x)°, m∠C=(8x+20)°, and m∠D=128°, what is m∠B
The value of m∠B is 212 - 24x.
How did we get the value?The totality of the angles in a quadrilateral is always amount to 360°. This is a primary property of all quadrilaterals, irrespective of their shape or size.
As a result, irrespective of the shape say if you are dealing with a square, rectangle, parallelogram, trapezoid, or any other type of quadrilateral, the totality of the angles will always be sum to 360°.
To determine the value of m∠B, one can employ the notion that the sum of the angles in a quadrilateral is 360°.
Thus,
m∠A + m∠B + m∠C + m∠D = 360
Substituting the given values, we get:
(16x)° + m∠B + (8x+20)° + 128° = 360
Simplifying and solving for m∠B, we get:
m∠B = 360 - (16x)° - (8x+20)° - 128°
m∠B = 212 - 24x
Therefore, the value of m∠B is 212 - 24x.

Given a figure.
The middle portion of the figure is not shaded.
It is required to find the perimeter of the non-shaded region.
It is given that:
The whole area of the shaded region = 78 inches²
The area of the small square which is situated at the bottom is:
Area of small square = 2 × 4

To find the area of the court without the white bands, we need to subtract the areas of the two white bands from the total area. Since the white bands are on the top and bottom, we need to subtract twice the product of the width of the court and the width of the white band. The width of the white band is not given, but we know that the width of the court will be reduced by 25%, so the new width of the court will be:
w' = w - 0.25w = 0.75w
Substituting the given values, we have:
[tex]$$\begin{aligned}A' &= lw' - 2(0.75w)(l) \ &= l(0.75w) - 1.5wl \ &= 0.5625lw\end{aligned}$$[/tex]
where A' is the new area of the court without the white bands. Substituting the values of l and w that we found earlier, we have:
[tex]$$A' = 0.5625 \cdot 23.76 \cdot 10.97 \approx 146.17 \text{ m}^2$$[/tex]
Therefore, the new area of the court is reduced by 25%.
To find out if the width of the land is also reduced by 25%, we need to compare the original width w with the new width w'. We have:
[tex]$w' = 0.75w$$[/tex]
Dividing both sides by w, we get:
[tex]$\frac{w'}{w} = 0.75$$[/tex]
This means that the new width w'$ is 75% of the original width w. Therefore, the width of the land is reduced by 25%, just like the area.

x =[?]^
from the given circle having tangents, the value of x is 130°.
What does a tangent line mean?A line that touches a curve at one point, y = f(x), is said to be the curve's tangent line. (x0, y0). The point at which it is drawn is substituted into the derivative f'(x) to find its slope (m), and y - y0 = m is used to find its equation. (x - x0).
In geometry, a tangent is a straight line that touches a curve or a surface at a single point, without intersecting it at that point. In the case of a curve, the tangent line at a point on the curve has the same slope as the curve at that point.
In trigonometry, the tangent is a mathematical function that relates the angles of a right triangle to the ratio of the length of the opposite side to the length of the adjacent side.
From the given figure,
We know that
50 + AB = 180
AB = 180 - 50
AB = 130
The value of x or arc AB is 130°.
