The deadweight loss caused by a subsidy is the amount of economic welfare that is lost because of the subsidy. In this example, the deadweight loss caused by the subsidy is $800. Therefore, correct option will be D.$800.
This occurs because the subsidy distorts the market by creating a price below the market equilibrium. This results in an inefficient distribution of resources as some consumers are willing to pay a higher price than the subsidized price.
Additionally, it creates an excess demand for the good, resulting in an over-allocation of resources. In this case, the deadweight loss is the difference between the market price and the subsidized price, which is $800. The deadweight loss is a negative externality of subsidies, as it reduces the overall efficiency of the market.

Step-by-step explanation:
Since the two horizontal lines are parallel, we have that triangle CDG and triangle CEF are similar (corresponding points in that order). Therefore, using similarity, CD/CG = CE/CF. Therefore 3/4 = 9/(4+x).

a freight train is leaving from hanford is 14 mph slower than the passenger train which also leaves from hanford. the passenger train travels 400 miles in the same amount of time that the freight train travels 330 miles. what is the speed of the passenger train?
The speed of the passenger train is 80 mph.
Let's call the speed of the passenger train "p" and the speed of the freight train "f". We know that "p" = "f" + 14, and that the time it takes for the two trains to cover their respective distances is the same.
Therefore, we can write the equation:
400/p = 330/f
Expanding the second term and substituting "p" for "f" + 14:
400/p = 330/(p - 14)
Cross multiplying and simplifying:
400 * (p - 14) = 330 * p
Expanding both sides:
400p - 5600 = 330p
Subtracting 330p from both sides:
70p = 5600
Dividing both sides by 70:
p = 80 mph
So the speed of the passenger train is 80 mph.

Surveys have become an integral part of our lives. Because it is so important that every citizen have the ability to interpret survey results, surveys are the focus of this project.
The Gallup Poll recently conducted a survey of 2,558 U. S. Adults and found that 46% of those surveyed have dealt with substance abuse in their families
The minimum sample size required will be 231.
What is Sample Size?
The act of deciding how many observations or replicates to include in a statistical sample is known as sample size determination. The sample size is an important aspect of any empirical study whose purpose is to draw conclusions about a population from a sample.
The sample size(n) is 2558.
p = 46%
= 0.46 sample fraction of US adults who had experienced with substance misuse in their relatives
1) Where, 0.05/2 (n is the crucial value of z for two tailed test at 0.05 level of significance = 1.96) is the 95% CI for the population proportion of adults in the United States who had dealt with substance misuse in their family (P). (This can be acquired from the z table by locating the z that corresponds to an area close to 0.05/2).
Hence, the confidence interval is given by
= [0.46 ± 0.02]
= [0.44, 0.48]
As a result, we are 95% confident that the population share of US individuals who have experienced substance misuse in their relatives will fall between 0.44 and 0.48
2) Margin of error = E
= 0.02
3) Null hypothesis 0.4 percent of US people have dealt with substance misuse in their families.
P = 4/10
= 0.4
Alternative hypothesis More than 0.5 percent of US individuals have dealt with substance misuse in their relatives.
P > 0.4
95% confidence interval is - [0.44, 0] 48]
We may reject the null hypothesis since the confidence interval does not include the null value of population proportion (0.4)
As a result, we have enough evidence that more than four out of every ten US adults have dealt with substance misuse in their families.
As a result, the newspaper could make the assertion.
4) According to the Gallop Poll poll of 2558 US individuals, more than four out of ten US citizens have dealt with substance misuse in their families.
5) The required minimum sample size is given by:
P is the specified value of population proportion under the null hypothesis = 0.4
= (1.96/0.02)² (0.4) (1 - 0.4)
= [tex]98^{2}[/tex] (0.4) 0.6
= 230.5
So, the minimum sample size required will be 231.
Since, the sample size taken in survey (2558) is more than 231, the sample size taken is not too small.

Answer:
b. stratosphere
Step-by-step explanation:
The ozone layer, located in the stratosphere is responsible for absorbing the most UV radiation. This is because the ozone molecule (O3) is able to absorb UV radiation due to its molecular structure, specifically the presence of three oxygen atoms which allows it to efficiently absorb the UV-C radiation (the most damaging to living organisms). This protects life on Earth from harmful effects of UV radiation, such as DNA damage, skin cancer and other harmful impacts on plants and marine life.

find the length of AB

Answer:
this can be solved using trigonometry
describe all unit vectors orthogonal to both of the given vectors.
The unit vector orthogonal to both A and B is u = (0.23, -0.92, 0.15).
Given vectors:
A = (2, 3, 4)
B = (1, -1, 4)
A unit vector is a vector with a magnitude of 1. Two vectors are orthogonal if the angle between them is 90 degrees. In order to find unit vectors orthogonal to both A and B, we must first compute the cross product of A and B. The cross product of two vectors is a vector perpendicular to both of the given vectors and can be denoted by A × B.
The cross product of A and B is given by:
A × B = (3, -12, 2)
To normalize this vector and find the unit vector, we must divide the vector by its magnitude. The magnitude of the vector A × B is equal to the square root of the sum of the squares of its components. We can write this as:
|A × B| = √(3^2 + (-12)^2 + 2^2) = √(169) = 13
Therefore, the unit vector orthogonal to both A and B is given by:
A × B/|A × B| = (3/13, -12/13, 2/13)
This vector can also be written in terms of its unit components, as:
u = (0.23, -0.92, 0.15)
Therefore, the unit vector orthogonal to both A and B is u = (0.23, -0.92, 0.15).

How do you fully simplify (3)/(2x+12) - (x-15)/(x^2-2x-48)?
Answer:
Step-by-step explanation:
4564. 2 75444214///4222.-112
The fully simplified form of the expression is [tex]\frac{3}{2x+12}-\frac{-3}{x-8} +\frac{4}{x+6}[/tex]
What do you mean by quadratic equation?A quadratic equation is a type of polynomial equation that has the general form ax^2 + bx + c = 0, where a, b, and c are coefficients and x is an unknown variable. The equation has two solutions, which can be found using the quadratic formula x = (-b ± √(b^2 - 4ac)) / 2a, where the ± symbol indicates that there are two possible solutions.
Quadratic equations are used to model a variety of real-world phenomena, such as the motion of objects under the influence of gravity, the path of a projectile, and the growth of a population over time. They are also used to describe the parabolic shape of curves and to solve optimization problems, such as finding the maximum or minimum value of a function
We can simplify the expression as follows:
[tex]\frac{3}{2x+12} =\frac{x-15}{x^{2} -2x-48}[/tex]
First, we'll simplify the denominators. To do this, we can factor the quadratic expression x² - 2x - 48:
x² - 2x - 48 = (x - 8)(x + 6)
Now we can rewrite the denominators:
[tex]\frac{3}{2x+12}-\frac{x-15}{(x-8)(x+6)}[/tex]
Next, we'll simplify the fraction in the second term using partial fraction decomposition:
[tex]\frac{x-15}{(x-8)(x+6)} =\frac{A}{x-8}+\frac{B}{x+6}[/tex]
where A and B are constants that we can find by multiplying both sides by (x - 8)(x + 6) and equating the numerators:
x - 15 = A(x + 6) + B(x - 8)
Expanding both sides:
x - 15 = Ax + 6A + Bx - 8B
Comparing coefficients:
-15 = Ax + 6A + Bx - 8B
1 = A + B
8B = Ax + 6A + 15
-6A = -15 - Ax - 8B
-6A = -15 - (A + B)x - 8B
-6A = -15 - x + 7x
-6A = -15 - x + 7x
-6A = -15 + 6x
Solving for A and B, we have:
A = -3
B = 4
So, the second term can be written as:
[tex]\frac{x-15}{(x-8)(x+6)} =\frac{-3}{x-8}+\frac{4}{x+6}[/tex]
Putting everything together, we have:
[tex]\frac{3}{2x+12} -\frac{x-15}{(x-8)(x+6)} =\frac{3}{2x+12}-\frac{-3}{x-8} +\frac{4}{x+6}[/tex]
which is the fully simplified form of the expression.

Three tickets in switzerland plus two tickets in japan would cost $73.75. how much does an abt movie ticket cost in each of these countries?
The cost of Japan and Switzerland tickets are 17.15 dollars and 13.15 dollars respectively.
How to find the cost of each ticket in each country?it would cost $77.75 to buy three tickets in Japan plus 2 tickets in Switzerland. Three tickets in Switzerland plus two tickets in japan would cost $73.75.
Using system of equation,
let
x = cost of each ticket in Japan
y = cost of each ticket in Switzerland
Therefore,
3x + 2y = 77.75
2x + 3y = 73.75
Multiply equation(ii) by 1.5
3x + 2y = 77.75
3x + 4.5y = 110.625
subtract the equations
2.5y = 32.875
y = 32.875 / 2.5
y = 13.15 dollars
Hence,
3x + 2y = 77.75
3x = 77.75 - 2y
3x = 77.75 - 2(13.15)
3x = 77.75 - 26.3
x = 51.45 / 3
x = 17.15 dollars

Triangle ABC is graphed on a coordinate plane, as shown.
The coordinates of the pre-image are A(2,2) B(4,4) and C(-4,2). If the triangle was dilated by a scale factor of 2 with a center of dilation at the origin what are the coordinates of the vertices of ΔA′B′C′?
The new vertices of ΔA'B'C' are A'(4, 4), B'(8, 8), and C'(-8, 4)
What is center of dilation?
A dilation's center is a fixed point in the plane around which all points expand or shrink. Under a dilation (k 1), the sole invariant (not changing) point is the center, which might be within, outside, or on a figure.
The center of dilation is the origin, so to find the new coordinates of each vertex, we need to multiply the original coordinates by the scale factor of 2.
A(2, 2) becomes A'(2 * 2, 2 * 2) = A'(4, 4)
B(4, 4) becomes B'(4 * 2, 4 * 2) = B'(8, 8)
C(-4, 2) becomes C'(-4 * 2, 2 * 2) = C'(-8, 4)
So, The new vertices of ΔA'B'C' are A'(4, 4), B'(8, 8), and C'(-8, 4).

Determine whether the following relation repreent y
a a function of x
5x3y=15
The given equation does not represent y as a function of x.
A relation is a function if for every unique x value, there exists only one unique y value. The equation 5x³y = 15 does not define a unique value for y for a given value of x, and therefore does not represent y as a function of x.
Function Of X, Y OutputThe equation 5x³y = 15 does not represent y as a function of x. A function must have exactly one output value for each input value, but this equation doesn't have the unique output restriction.
The equation 5x³y = 15 represents a 3-dimensional surface in the x-y-z plane, where z = 5x³y. It does not define y as a function of x, because for a given x there can be multiple values of y that satisfy the equation. To define y as a function of x, additional information, such as an equation that relates y and x in a one-to-one manner, is needed.

Solve the following initial value problem:
dy/dt=t^2+1, t ≥ 0, y = 6 when t=0
The solution of the initial value problem is [tex]y = (t^3/3 + t^2 + t + 6)e^{(t^3/3 + t)}[/tex]
A differential equation is a mathematical equation that relates a function and its derivatives to some independent variables.
In this case, the differential equation is given by:
dy/dt = t² + 1, t ≥ 0
with the initial value y = 6 when t = 0.
To solve this initial value problem, we can use the method of integrating factor.
We can find the integrating factor for this differential equation by using the formula:
[tex]= > e^{\intP(t)dt,[/tex]
where P(t) = t² + 1
So,
[tex]= > e^{\int P(t)dt} = e^{t^3/3 + t}[/tex]
By the product rule, we have:
[tex]= > d/dt(e^{t^3/3 + t)y} = d/dt(e^{t^3/3 + t)(t^2 + 1)})[/tex]
We can evaluate the integral on the right side using standard integration techniques, and we get:
[tex]= > e^{t^3/3 + t}y = e^{(t^3/3 + t)(t^3/3 + t^2 + t + C)[/tex]
Finally, we can isolate y by dividing both sides of the equation by e^(t^3/3 + t):
[tex]= > y = (t^3/3 + t^2 + t + 6)e^{(t^3/3 + t)}[/tex]
To find the value of C, we can use the initial value y = 6 when t = 0:
6 = Ce⁰
So, C = 6.
Therefore, the solution to the initial value problem is:
[tex]y = (t^3/3 + t^2 + t + 6)e^{(t^3/3 + t)}[/tex]
