A slow-moving barge moves through the sea at a speed of 4 km/h. It travels 8 miles upstream in the same amount of time as a barge traveling 24 miles downstream with the current. The current moves at a 2 km/h rate.

Let’s start by using the formula for distance, rate, and time:

Distance = rate x time

Let’s assume that the rate of the current is r km per hour.

Going upstream (against the current), the effective rate of the barge is:

4 – r km per hour

Going downstream (with the current), the effective rate of the barge is:

4 + r km per hour

We are told that the time it takes the barge to travel 8 miles upstream is the same as the time it takes to travel 24 miles downstream. Using the formula, we can set up the following equation:

8 / (4 – r) = 24 / (4 + r)

We can simplify this equation by cross-multiplying:

8(4 + r) = 24(4 – r)

Expanding and simplifying, we get:

32 + 8r = 96 – 24r

Adding 24r and subtracting 32 from both sides, we get:

32r = 64

Dividing both sides by 32, we get:

R = 2

Therefore, the rate of the current is 2 km per hour.

An object's methods are the tasks or functions that the object performs when it receives a command to do so.

The methods of an object describe what the object can perform. In object-oriented programming (OOP), objects are a key element of the language. Each object has a collection of methods that it can perform.

Methods are similar to functions or procedures in traditional programming. They're the code that the object executes in response to a command. Because objects have methods, programming in object-oriented programming (OOP) languages involves defining the object classes, which specify the methods and properties that each object in that class will have.

Roles:- Roles specify the various abilities that an object can perform. In object-oriented programming (OOP), these roles are often defined through interfaces, which specify the set of methods that an object must implement in order to fulfill the role. The role of an object is determined by the methods that it implements.

Utilities:- Utilities are typically unrelated to an object's role, but rather are commonly used functions that are available throughout a system or application. They often provide functionality that is required by many different objects in the system.

The value of the holiday package indexed for inflation over 4 years is $16,236.00, calculated using the formula Value after inflation = Value before inflation × (1 + inflation rate)ⁿ.

To calculate the value of the holiday package indexed for inflation over 4 years, we can use the formula:

Value after inflation = Value before inflation × (1 + inflation rate)ⁿ

("ⁿ" represents number of years)

where the inflation rate is given as a decimal.

Substituting the given values, we get:

Value after inflation = $15000 × (1 + 0.02)⁴

= $15000 × 1.0824

= $16,236.00

Therefore, the value of the holiday package indexed for inflation over 4 years is $16,236.00.

To solve fg(x) = gf(x), we need to find the values of x that satisfy this equation. First, let's calculate fg(x):fg(x) = f(g(x)) = f(x-5) = (x-5)² + 1 Now, let's calculate gf(x):gf(x) = g(f(x)) = g(x² + 1) = (x² + 1) - 5 = x² - 4So, we have the equation:(x-5)² + 1 = x² - 4 Expanding (x-5)², we get:x² - 10x + 26 = x² - 4 Simplifying, we get:-10x + 26 = -4-10x = -30x = 3 Therefore, the solution to fg(x) = gf(x) for all values of x is x = 3.

The bottom of the ladder is moving at a rate of 4/3 ft per second.

To solve the problem, we can use the Pythagorean Theorem:[tex]$x^2 + y^2 = 64$[/tex], where x is the distance from the wall to the bottom of the ladder and y is the length of the ladder. We differentiate this equation with respect to time t and use the chain rule to get [tex]$\frac{d}{dt} (x^2 + y^2) = \frac{d}{dt} 64$[/tex]

Simplifying, we get

[tex]$2x \frac{dx}{dt} + 2y \frac{dy}{dt} = 0$[/tex]

When the bottom of the ladder is 4 feet from the wall, we have x = 4 and y = 8, so we can substitute these values into our equation and solve for [tex]$\frac{dx}{dt}$[/tex]:

[tex]$2(4)\frac{dx}{dt} + 2(8)(-2) = 0$[/tex]

Answer:

The shape of each cut surface is a rectangle. The dimensions of the first cut surface are 8 inches by 10 inches, and the dimensions of the second cut surface are 10 inches by 20 inches.

The area of the first cut surface is 8 inches x 10 inches = 80 square inches. The area of the second cut surface is 10 inches x 20 inches = 200 square inches.

To find the total area Jenny needs to paint, we need to add the area of the first cut surface to the area of the second cut surface.

Total area = Area of first cut surface + Area of second cut surface

Total area = 80 square inches + 200 square inches

Total area = 280 square inches

Therefore, Jenny needs to paint a total area of 280 square inches.

when the distance between the top of the rod and the foot of the wall is 152 inches, the distance between the bottom of the rod and the foot of the wall is decreasing at a rate of approximately 19.08 inches per second.

In this case, we are given that the distance between the top of the rod and the foot of the wall is decreasing at a rate of 9 inches per second. We want to find the rate at which the distance between the bottom of the rod and the foot of the wall is changing.

We can start by using the Pythagorean theorem to relate the three distances involved: the height of the rod (h), the distance between the top of the rod and the foot of the wall (x), and the distance between the bottom of the rod and the foot of the wall (y). Specifically, we have:

[tex]h^2 = x^2 + y^2[/tex]

To find the rate at which y is changing, we can take the derivative of both sides of this equation with respect to time (t), using the chain rule:

2h dh/dt = 2x dx/dt + 2y dy/dt

We are given that dh/dt = -9 inches per second (since h is decreasing). We also know that h = 172 inches and x = 152 inches (when y = 0). Substituting these values and solving for dy/dt, we get:

dy/dt = (h/x) * (dx/dt - (x/y) * dh/dt)

dy/dt = (172/152) * (-9 - (152/y) * 9)

dy/dt = -19.08 inches per second (rounded to two decimal places)

Yes, if is a critical point of a function with continuous second derivatives, then it is a stationary point.

This means that the function's derivative is equal to 0 at that point and it is neither increasing or decreasing.

A stationary point is a point on the graph of a function where the function's derivative is equal to 0. This is an important property of a function and it can be used to determine the properties of the function.

At a stationary point, the rate of change of the function is equal to 0, so the function is neither increasing or decreasing. In other words, the function is neither increasing or decreasing at that point.

This property can be used to analyze the function and determine its characteristics. For example, it can be used to identify local minima or maxima.

The candy store will use 103 grams of sugar in 10 hours.

To find out how many grams of sugar the store will use in 10 hours, we can simply multiply the amount of sugar used in one hour (10.3 grams) by the number of hours (10).

To solve the problem, we use a simple multiplication formula: the amount used per hour (10.3 grams) multiplied by the number of hours (10) to find the total amount of sugar used in 10 hours.

We can interpret this problem using a rate equation: the rate of sugar usage is 10.3 grams/hour, and the time period is 10 hours. Multiplying the rate by the time gives the total amount of sugar used.

So the calculation would be:

10.3 grams/hour x 10 hours = 103 grams

Answer:

Step-by-step explanation:

Answer:

See below, please.

Step-by-step explanation:

Using the zero product property, we can set each factor equal to zero and solve for x:

(x² - 9)(x + 4) = 0

(x² - 9) = 0 or (x + 4) = 0

For the first factor, we can factor it further as the difference of squares:

(x + 3)(x - 3) = 0

So, either (x + 3) = 0 or (x - 3) = 0, giving us:

x = -3, x = 3, or x = -4

Therefore, the values of x for which (x² - 9)(x + 4) = 0 are -3, 3, and -4.
