True, the classic tradeoff between "guns and butter" states that when a society spends more on national defense, it has less to spend on consumer goods to raise the standard of living.
The production possibility curve, which illustrates the concept of opportunity cost, has a famous economic example known as the "guns-and-butter" curve. One must decide how much of each good to create in a hypothetical economy with only two goods.
An economy must decrease its production of butter (food) as it increases its production of firearms (military spending), and vice versa. According to the guns-and-butter curve, you can only acquire something if you offer something else in exchange.

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
for example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
A television show aired once a week for 4.5 years.
So, In four years number of weeks are

A number is multiplied by 6, and that product is added to 4. The sum is equal to the product of 2 and 23. Find the number.
Answer:
The number is 7
Step-by-step explanation:
1. Create the equation needed to solve this
Lets think of a number as x. We have a number multiplied by 6 and have 4 added to it.
We get:
6x + 4
Now this sum is equal to the product of 2 and 23. We connect this to get
6x + 4 = 2(23)
We can simplify this to
6x + 4 = 46
2. Solve for x
6x + 4 = 46
Subtract 4 from both sides
6x = 42
Divide both sides by 6
x = 7

A coefficient of -1 represents a perfect negative correlation, meaning that as one variable increases, the other variable decreases.
A coefficient of 0 represents no correlation, meaning that there is no linear relationship between the two variables.
A coefficient of 1 represents a perfect positive correlation, meaning that as one variable increases, the other variable also increases.
Each year, a physicist measures the remaining radioactivity in a sample. she finds that it reduces by 18% each year. if there was 1.52 g of radioactive material left after 4 years}
a. Find the initial quality of radioactive material
b. Hoy many more years will it take for the amount of radioactive material to reduce to 0.2 g?
a. The initial quantity of radioactive material is 0.68 g.
b. It will take an additional 7.15 years for the amount of radioactive material to reduce to 0.2 g.
a. In order to find the initial quality of radioactive material, we will use the formula:
Initial Quality = Final Quantity * (1 - Reduction Rate)^Years
We know that -
the final Quantity is 1.52 g, the reduction rate is 18% (or 0.18), and the number of years is 4.
Initial Quantity = 1.52 g * [tex](1 - 0.18)^4[/tex]
Initial Quantity = 1.52 g * 0.452
Initial Quantity = 0.68 g
Hence, the initial quantity of the radioactive material is 0.68 g.
b. In order to find how many more years it will take for the amount of radioactive material to reduce to 0.2 g, we will use the formula:
Years = log(Final Quality / Initial Quality) / log(1 - Reduction Rate)
We know that -
the final quality is 0.2 g, the initial quality is 0.68 g, and the reduction rate is 18% (or 0.18).
Years = log(0.2 / 0.0.68) / log(1 - 0.18)
Years = 7.15
Therefore, it will take an additional 7.15 years for the amount of radioactive material to reduce to 0.2 g.

To plot a graph, you need to have a set of x and y values that correspond to points on the graph. Once you have the data, you can use a tool such as a graphing calculator, spreadsheet software or specialized graphing software to plot the points and create the graph.
This sequence appears to be a geometric sequence. In a geometric sequence, the ratio between any two consecutive terms is always the same. In this case, the ratio between consecutive terms decreases by a factor of 1/4 each time.
The first five terms of the sequence are: (64,1), (16,2), (4,3), (2,4), (0,5)
A recursive definition of the sequence is a definition that expresses each term of the sequence in terms of one or more of the previous terms.

?
12
74°
Answer: We can use trigonometry to solve this problem.
Let x be the length of the ladder, and h be the height of the ladder.
We can use the tangent function to relate the angle of elevation, the length of the ladder, and the height of the ladder:
tan(74°) = h / x
We know that x = 12 ft and we can find h.
We can cross multiply and solve for h:
x * tan(74°) = h
12 * tan(74°) = h
We can use a calculator to find the value of h, this will give us the height of the ladder.
Finally, we can use the Pythagorean theorem to find the length of the ladder:
x^2 = h^2 + 12^2
x = √(h^2 + 12^2)
Round your answer to the nearest tenth, we have x = √(h^2 + 12^2)
We can use the value of h to find the length of the ladder.
However, without the value of h it is not possible to find the length of the ladder.

The first plane is farther from the airstrip after the second leg
Which plane is farther from the airstrip after the second leg?The first plane
Initial distance = 150 miles west
Additional distance = 220 miles 30 degrees SW
This means that
Additional distance = 220 * cos(30) miles SW
Additional distance = 190.53 miles
Total distance = 150 + 190.53 = 340.53
The second plane
Initial distance = 220 miles east
Additional distance = 150 miles x degrees SE
This means that
Additional distance = 150 * cos(x) miles SW
Total distance = 220 + 150 cos(x)
Given that
x < 30
We have
Second plane < First plane
220 + 150 cos(x) < 340.53

Angela observes that a drone is flying horizontally at a constant height of 5m above the ground. If the drone is flying in the opposite direction from Angela's location at a speed of 1m/s determine the rate at which the angle of elevation (theta) decreases at the moment when (theta)=pi/6
The rate of change of the angle of elevation is approximately - 2.597 degrees per second (-0.045 radians per second). (Correct choice: C)
How to determine the rate of change of the angle of elevation
In this problem we find the case of a drone that travels horizontally, at constant height (h), in meters. The rate of change of the angle of elevation (θ'), in degrees per second, can be found from trigonometric functions and derivatives:
tan θ = y / x
Where:
x - Horizontal distance, in meters. y - Vertical distance, in meters.By derivatives:
sec² θ · θ' = - y · x⁻² · x'
θ' = - (y · x⁻² · x') / sec² θ
Where x' is the speed of the drone, in meters per second.
If we know that y = 5 m, θ = π / 6 and x' = 5 m / s, then the rate of change of the angle of elevation is:
x = y / tan θ
x = (5 m) / tan (π / 6)
x ≈ 2.887 m
θ' = - [(5 m) · (2.887 m)⁻² · (5 m / s)] / sec² (π / 6)
θ' ≈ - 2.597 degrees per second (- 0.045 radians per second)

$70 x m = $70m
The linear equation that represents the cost of plan B = (cost per month x number of months) + cost of the phone
($50 x m) + $500
= $50m + $500
When the costs are the same, the two equations would be equal
$70m = $50m + $500
Solve for m:
Combine similar terms: $70m - $50m = $500
Add similar terms: $20m = $500
Divide both sides of the equation by 20 = 500 / 20
m = 25 months

the visualization below shows voting patterns in the united states, canada, and mexico in the united nations general assembly on a variety of issues. specifically, for a given year between 1946 and 2015, it displays the percentage of roll calls in which the country voted yes for each issue. this visualization was constructed based on a dataset where each observation is a country/year pair.1
(a) List of variables is Years, Country, Arms control and disarmament, colonialism, economic development, human rights, nuclear weapons, and materials, and Palestinian conflict.
(b) Each variable is numeric if the variable assumes number values and it will be categorical if it assumes labels.
(a) The list of variables is:
The variables that can be used in this visualization can be Years, Country, Percentage that said yes, Arms control and disarmament, colonialism, economic development, human rights, nuclear weapons, and materials, and Palestinian conflict.
(b) Category of different variables:
Years: Numerical and discrete
years are number values but the voting has not been done in the same interval so it is a numerical and discrete variable.
Country: Categorical and not ordinal
country name assumes as labels hence it is a categorical variable.
The percentage that said yes: Numerical and continuous
The percentage indicates number values so it is a numerical value.
And following is also assumed as a label so these are also categorical values:
Arms control and disarmament: categorical and not ordinal
colonialism: categorical and not ordinal
economic development: categorical and ordinal
human rights: categorical and ordinal
Nuclear weapons and materials: categorical and not ordinal.
Palestinian conflict: Categorical and not ordinal

Answer:
Step-by-step explanation:
state the minimum or maxium value of y=2x^2
Since dy/dx > 0 for x = -7 and dy/dx < 0 for x = -9 , So this is a turning point.
What is Algebraic expression ?
Algebraic expression can be defined as the combination of variables and
constants.
So, the given expression ,
y = 2x^2 + 32x -4
So, first we have to find the derivative dy/dx
and than solve for dy/dx = 0
The derivative of any term x^n is equals to n*x^n-1 so for this polynomial
2x^2 + 32x - 4
The derivative could be
2.2x+1.32+0.-4
dy/dx = 4x+32
To calculate the turning points
let this equals to 0.
4x+32 = 0
x = -32/4
x = -5
By substituting this into the original equation, the turning point is at (-8,-137).
Therefore, Since dy/dx > 0 for x = -7 and dy/dx < 0 for x = -9 , So this is a turning point.
