Answer:

23 gallons per minute

Step-by-step explanation:

The Volume of Water = 1380 gallons

Time = 1 hour

Since we want to determine the rate at which the water is flowing out of the pipe in gallons per minute, we convert our time from hour to minutes.

1 hour = 60 Minutes

Rate= Volume ÷ Time

 = 1380 ÷ 60

=23 gallons per minute

The water is flowing out of the pipe at a rate of 23 gallons per minute.

The exponential equation to model Puerto Rico's population in millions after t years is:

[tex]P(t) = 3.72 \times e^(^-^0^.^1^1^8^t^).[/tex]

To model Puerto Rico's population in millions after t years using an exponential equation, we can use the following formula:

[tex]P(t) = P₀ \times e^(^r^t^),[/tex]

where:

P(t) is the population at time t,

P₀ is the initial population (in 2010),

e is the base of the natural logarithm (approximately 2.71828), and

r is the growth rate.

Given that the population of Puerto Rico in 2010 was approximately 3.72 million people, we can substitute P₀ = 3.72 into the equation.

Now, to determine the growth rate (r), we need to consider the population decrease of 11.8% since 2010. We can convert this percentage into a decimal by dividing it by 100, so 11.8% becomes 0.118.

Since the population decreased, we use a negative growth rate, so r = -0.118.

Therefore, the exponential equation to model Puerto Rico's population in millions after t years is:

[tex]P(t) = 3.72 \times e^(^-^0^.^1^1^8^t^).[/tex]

This equation takes into account the initial population in 2010 and the negative growth rate to project the population in millions for any given year (t) after 2010.

If two different signs are multiplied, the product obtained should be multiplied by another negative sign. We would then get the last sign as positive.

When two different signs are multiplied, the product obtained should be multiplied by another negative sign. When two different signs are multiplied, we obtain either a positive or negative product depending on the signs. If both signs are positive, the product is positive. If both signs are negative, the product is also positive.

However, if two different signs are multiplied, the product is negative. This is the first step in answering the question.

After we obtain a negative product by multiplying two different signs, we are to multiply this product with another negative sign. Multiplying a negative product with another negative sign would yield a positive result. This is because the product of two negatives is positive.

To understand this concept, we can use numbers as examples. Let us say we want to multiply -5 and 7. The product of -5 and 7 is -35 since we are multiplying two different signs. Now we are to multiply this product with another negative sign, say -1. Multiplying -35 and -1, we obtain +35, which is the answer to the problem.

Answer: The caret symbol (^) represents a power.

Step-by-step explanation:

In short, a power or an exponent indicates the number of times a number needs to be multiplied by itself. The caret can be used to represent a number that is to be used as an exponent.

For example, 5^2 is the same thing as [tex]5^2[/tex]. [tex]5^{2} =[/tex] 5 x 5 = 25.

In the example you provided, 1200 x (1.0041666667) ^ 48, the caret means that you need to raise 1.0041666667 to the power of 48.

Therefore, the answer is A. {5, 5√3, 10}.

The set of values {5, 5√3, 10} could be the side lengths of a 30-60-90 triangle.

In a 30-60-90 triangle, the sides are in a specific ratio. The ratio is 1 : √3 : 2, where the shortest side (opposite the 30-degree angle) has length x, the side opposite the 60-degree angle has length x√3, and the hypotenuse (opposite the 90-degree angle) has length 2x.

Let's check if the given set of values satisfies this ratio:

   If x= 5, then the side opposite the 60-degree angle should be 5√3, and the hypotenuse should be 10. These values match the ratio, so the set {5, 5√3, 10} could be the side lengths of a 30-60-90 triangle.

The domain for the function is the interval [0, 14], which represents the feasible values for the length of one side of the rectangular garden.

To determine the appropriate values of the domain for the graph of the function [tex]A(t) = -t^2 + 14t[/tex], we need to consider the situation and the constraints given.

The function A(t) represents the area of the rectangular garden as a function of the length of one of its sides, which is denoted by t.

We are also told that Marama plans to fence the garden with 28 feet of wired fencing.

Now, let's break down the problem and find the appropriate values for the domain.

We know that the perimeter of a rectangle is the sum of all its sides. In this case, since we have a rectangular garden, the perimeter can be represented as:

[tex]Perimeter = 2t + 2w[/tex],

where t is the length of one side (the width) and w is the length of the other side (the width).

The problem states that Marama plans to use 28 feet of wired fencing. Therefore, the perimeter of the garden must equal 28 feet:

[tex]2t + 2w = 28[/tex].

Simplifying this equation, we have:

[tex]t + w = 14[/tex].

We can express w in terms of t as [tex]w = 14 - t[/tex].

The area of a rectangle is given by the product of its length and width:

[tex]Area = t \times w[/tex].

Substituting the expression for w from step 2, we have:

[tex]A(t) = t \times (14 - t)[/tex].

Simplifying further:

[tex]A(t) = 14t - t^2[/tex].

To determine the appropriate values of the domain, we need to consider the context of the problem. Since we are dealing with a physical garden, both the length and width must be positive numbers. Additionally, the values of t must be feasible given the constraints of the perimeter.

We know that [tex]t + w = 14[/tex], so [tex]t + (14 - t) = 14[/tex], which simplifies to [tex]14 = 14[/tex].

This shows that the value of t can range from 0 to 14, inclusive.

Therefore, the appropriate values of the domain for the graph of the function [tex]A(t) = -t^2 + 14t[/tex] are [tex]t \epsilon [0, 14][/tex].

To illustrate this graphically, we can plot the function [tex]A(t) = -t^2 + 14t[/tex] and mark the appropriate values of the domain on the x-axis (representing t):

The function f(x) = x + 10√(9 - x) is increasing on the interval (-∞, 9) and decreasing on the interval (9, ∞).

To determine the intervals on which the function is increasing or decreasing, we need to find the derivative of the function and analyze its sign.

Let's find the derivative of the function f(x) = x + 10√(9 - x) with respect to x.

f'(x) = 1 + 10 * (1/2) * (9 - x)^(-1/2) * (-1)

= 1 - 5√(9 - x) / √(9 - x)

= 1 - 5 / √(9 - x).

To analyze the sign of the derivative, we need to find the critical points where the derivative is equal to zero or undefined.

Setting f'(x) = 0:

1 - 5 / √(9 - x) = 0

5 / √(9 - x) = 1

(√(9 - x))^2 = 5^2

9 - x = 25

x = 9 - 25

x = -16.

The critical point is x = -16.

We can see that the derivative f'(x) is defined for all x values except x = 9, where the function is not differentiable due to the square root term.

Now, let's analyze the sign of the derivative f'(x) in the intervals (-∞, -16), (-16, 9), and (9, ∞).

For x < -16:

Plugging in a test value, let's say x = -17, into the derivative:

f'(-17) = 1 - 5 / √(9 - (-17))

= 1 - 5 / √(9 + 17)

= 1 - 5 / √26

≈ 1 - 0.97

≈ 0.03.

Since f'(-17) is positive, the function is increasing in the interval (-∞, -16).

For -16 < x < 9:

Plugging in a test value, let's say x = 0, into the derivative:

f'(0) = 1 - 5 / √(9 - 0)

= 1 - 5 / √9

= 1 - 5 / 3

≈ 1 - 1.67

≈ -0.67.

Since f'(0) is negative, the function is decreasing in the interval (-16, 9).

For x > 9:

Plugging in a test value, let's say x = 10, into the derivative:

f'(10) = 1 - 5 / √(9 - 10)

= 1 - 5 / √(-1)

= 1 - 5i,

where i is the imaginary unit.

Since the derivative is not a real number for x > 9, we cannot determine the sign.

Combining the information, we conclude that the function f(x) = x + 10√(9 - x) is increasing on the interval (-∞, 9) and decreasing on the interval (9, ∞).

Also, let's represent the supplies the hikers have with "s."Given that after three days the hikers used 2/5 of their supplies, we can say that they have 3/5 of their supplies left. Hence,3/5s = Supplies remaining after 3 days, which means that2/5s = Supplies used in the first 3 daysWe need to find the number of days the hikers can travel before they have to turn around. So, we can say that the ratio of supplies used to the number of days traveled will be equal to the ratio of supplies remaining to the number of days remaining.2/5s ÷ 3 = (3/5s) ÷ dWe can simplify the above expression to find d as:d = (3/2) × 3/5 = 9/10 daysTherefore, the hikers can go forward for 9/10 days before they have to turn around.
