NATIONAL DEBT In 1915, the U.S. National Debt was approximately 3.1 × 10⁹ dollars. In 2015, the U.S. National Debt was approximately 5.9 × 10³ times more than in 1915. What was the U.S. National Debt in 2015?

Answer:

a. To find the volume when the width is 5 inches, we plug in w=5 into the equation:

V = 2w³ - 7w² + 3w

V = 2(5)³ - 7(5)² + 3(5)

V = 250 - 175 + 15

V = 90

Therefore, the volume is 90 cubic inches.

b. To factor the polynomial, we can first factor out a w:

V = w(2w² - 7w + 3)

Then we can factor the quadratic expression in parentheses:

V = w(2w - 1)(w - 3)

Each factor represents a dimension of the rectangular prism:

w is the width

2w - 1 is the length

w - 3 is the height

c. If the width is 5 inches, we can use the factorization from part b to find the other dimensions:

length = 2w - 1 = 2(5) - 1 = 9 inches

height = w - 3 = 5 - 3 = 2 inches

This means that the rectangular prism has dimensions 5 inches by 9 inches by 2 inches. We can also use the dimensions to calculate the volume:

V = 5 × 9 × 2 = 90 cubic inches

This is the same as the answer from part a.

d. The graph of the polynomial is:

Graph of the polynomial

The x-intercepts are approximately 0.5 and 3. These correspond to the widths at which the volume is 0, which means the rectangular prism has zero volume. In other words, the x-intercepts represent the points where the rectangular prism collapses into a flat shape.

e. The domain of the function is all real numbers, since we can plug in any width w and get a corresponding volume. The range of the function is also all real numbers, since the volume can be any positive or negative value depending on the width. Specifically, the range is (-∞, ∞).

The probability that a randomly selected unit will contain at least one surface-finish defect is 0.0952.

The number of surface finish flaws in this issue will follow a Poisson distribution, and since the mean is given, it is necessary to obtain the probability. More solutions will be found by using the Poisson distribution's normal approximation.

The following formula can be used to determine the likelihood that a randomly chosen unit will have at least one surface finish flaw:

The distribution's average and standard deviation are λ = 0.1

P(X ≥ 1) = 1 − P(X < 1)

P(X ≥ 1) = 1 − P(X = 0)

P(X ≥ 1) = 1 − [tex]\frac{e^{-0.1}(0.1)^0}{0!}[/tex]

After simplification

P(X ≥ 1) = 0.0952

When the equilibrium point is above the potential GDP line, the economy is experiencing inflationary pressure.

In the AD/AS model, whether the economy is in a recession is illustrated by how close the equilibrium is to the potential GDP line. The potential GDP line represents the maximum level of output that an economy can produce with its existing resources and technology.What is the AD/AS model?The AD/AS model is a graphical representation of the macroeconomic relationship between aggregate demand (AD) and aggregate supply (AS). This model is used to explain the behavior of the economy by demonstrating how changes in the level of aggregate demand and aggregate supply can impact the economy's level of output and prices.

The model's AD curve represents the total demand for all goods and services in an economy at different price levels. The AS curve represents the total supply of all goods and services in the economy at different price levels.

Step-by-step explanation:

Diana's average speed for the entire race was approximately 0.583 meters per second.

We can start by using the formula

average speed = total distance / total time

We know that Diana ran a total distance of 700 meters, and we can find the total time by adding the time for the first lap and the time for the second lap. Let's call the distance of each lap "x"

total distance = 700 meters

distance for each lap = x meters

So, the total time is

total time = time for first lap + time for second lap

To find the time for each lap, we can use the formula

time = distance / speed

For the first lap, we have

time for first lap = x / 7

For the second lap, we have

time for second lap = x / 5

So, the total time is

total time = (x / 7) + (x / 5)

We can simplify this by finding a common denominator

total time = (5x + 7x) / (35)

total time = (12x) / 35

Now, we can substitute the values we have into the formula for average speed

average speed = total distance / total time

average speed = 700 / [(12x) / 35]

average speed = (700 × 35) / (12x)

average speed = 204.166... / x

To find the average speed for the entire race, we need to find the value of "x" that makes this expression true. We know that the two laps are equal in distance, so we can set

x + x = 700

2x = 700

x = 350

Substituting this value of "x" into the expression for average speed, we get

average speed = 204.166... / 350

average speed ≈ 0.583 meters per second

The work required to pump all the water over the top edge of the cylindrical tank is approximately 83,500 kJ.

To calculate the work required to pump all the water over the top edge of the cylindrical tank, we need to determine the volume of the water in the tank and the force required to lift it to the top edge.

The volume of water in the tank can be found by multiplying the cross-sectional area of the tank by the depth of the water. Since the tank is cylindrical, the cross-sectional area is given by πr^2, where r is the radius of the tank. Therefore, the volume of water in the tank is:

V = πr^2h = π(6m)^2(5m) = 540π m^3

To lift the water to the top edge of the tank, we need to overcome the force of gravity acting on the water. The force required to lift an object of mass m against gravity is given by F = mg, where g is the acceleration due to gravity (9.81 m/s^2).

The mass of the water in the tank can be found by multiplying its volume by its density. The density of water is approximately 1000 kg/m^3. Therefore, the mass of the water in the tank is:

m = ρV = (1000 kg/m^3)(540π m^3) = 1.7 x 10^6 kg

The force required to lift the water to the top edge of the tank is:

F = mg = (1.7 x 10^6 kg)(9.81 m/s^2) = 16.7 x 10^6 N

To find the work required to lift the water, we need to multiply the force by the distance over which it acts. The distance is equal to the height of the water in the tank, which is 5 m.

Therefore, the work required to pump all the water over the top edge of the tank is:

W = Fd = (16.7 x 10^6 N)(5 m) = 83.5 x 10^6 J

Rounding to the nearest kilojoule, the work required is approximately 83,500 kJ.

Hope you understand :)

when some syrup from a bottle was poured into the container, it got half full. The volume of the syrup poured from the bottle into the container in millimeters is 576,000 cubic millimeters.

Since for solving the problem we need to find the volume of the container in millimeters. We are given the length, breadth, and height which are 12 cm,8 cm, and  36 cm.Now the volume of the container is:

V = l x w x h = 12 cm x 8 cm x 36 cm = 3,456 cubic cm. Now  we convert the above result  into millimeters by  multiplying by 1,000, so we get V= 3456 x 1000= 34560000 cubic mm

Now to find the volume of the syrup that was poured into the container,  we know that the container was one-third full before the syrup was added and half full after the syrup was added.onsidering x to be the volume of the syrup poured from the bottle into a container and n to be the volume of the syrup in the container after it was added:

1/3(V) + x = 1/2(V), where v is the  volume of the container in millimeters, so we substitute the calculated value of the volume we get :

=>1/3(V) + x = 1/2(V)

=>x = 1/2(V) - 1/3(V)

=> x = 1/6(V) = 1/6(3,456,000)  = 576,000 cubic mm

Equations are academic expressions that are used to demonstrate the equality of different academic figures. In this instance, normalization results in c + 7 rather than a singular formula that divides 12 into two components and can be applied to data obtained from y + 9.

Here,

We must isolate y on the left side of the equation in order to convert the provided equations to the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.

=> y = -x - 4:

=> x + y = -4

=> y = -x - 4

As a result, the equation has a slope of -1 and a y-intercept of -4, and is written as y = -x - 4.

=> y = 1/2x - 1:

=> y - 1/2x = -1

=> y - 1/2x + 1 = 0

The words with y and the constant term must be combined in order to represent this equation in slope-intercept form:
