The total distance of the obstacle course can be calculated by finding the distance between each pair of consecutive points and adding them up. The distance between two points (x1, y1) and (x2, y2) can be calculated using the formula: distance = sqrt((x2 - x1)^2 + (y2 - y1)^2).
Using this formula, we can calculate the distances between each pair of consecutive points as follows:
Start to Tire Race: distance = sqrt((-40 - (-40))^2 + (-30 - (-10))^2) = 20 yards
Tire Race to Rope Climb: distance = sqrt((40 - (-40))^2 + (-30 - (-30))^2) = 80 yards
Rope Climb to Monkey Bars: distance = sqrt((40 - 40)^2 + (20 - (-30))^2) = 50 yards
Monkey Bars to Finish: distance = sqrt((10 - 40)^2 + (20 - 20)^2) = 30 yards
Adding up all these distances, we get a total distance of 20 + 80 + 50 + 30 = 180 yards for the obstacle course.

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.

Find the open intervals on which the function f(x)= x+10sqrt(9-x) is increasing or decreasing.
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, ∞).

Puerto rico saw a population decrease of 11.8% since 2010 if the population of Puerto Rico in 2010 was approximately 3.72 million people right in exponential equation to model Puerto Rico's population in millions after t years
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 C = 4 feet and h = 5.25 feet, what is the area of the triangle opening?
The area of the triangle opening, with a base of 4 feet and a height of 5.25 feet, is 10.5 square feet.
To find the area of the triangle opening, we can use the formula for the area of a triangle, which is given by A = (1/2) * base * height. In this case, the base and height of the triangle are represented by the variables C and h, respectively.
Given that C = 4 feet and h = 5.25 feet, we can substitute these values into the formula:
A = (1/2) * 4 feet * 5.25 feet
Simplifying the expression, we have:
A = 2 feet * 5.25 feet
A = 10.5 square feet
Therefore, the area of the triangle opening is 10.5 square feet.
In conclusion, with a base of 4 feet and a height of 5.25 feet, the triangle opening has an area of 10.5 square feet.

Since function, g, has a domain of -20 ≤ x ≤ 5 and a range of -5 ≤ g(x) ≤ 45 and that g(0) = -2 and g(-9) = 6, the statement that could be true for g is: A. g(-13) = 20.
How to determine the true statement for function g?Based on the information provided in this scenario, the domain and range of this function g(x) in interval notation are as follows:
Domain = -20 ≤ x ≤ 5 or [-20, 5]
Range = -5 ≤ g(x) ≤ 45 or [-5, 45]
Function g(0) = 2 is simply a false statement because it was explicitly stated that g(0) = -2. Additionally, g(-4) = -11 is a false statement because it is outside the scope of the given range for this function.
Furthermore, the function g(7) = -1 is a false statement because it is not within the domain for the given function. However, we can logically deduce that the function g(-13) = 20 is a true statement because it is within the domain for the given function and it would produce an output that is within the scope of the given range for this function.

After three days, a group of hikers discovers that they have used 2/5 of their supplies. At this rate, how many days can they go forward before they have to turn around?
Answer:
hikers can travel before they have to turn around be "d" days. 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.
22 people got off a bus. 17 people remained on the bus. How many people were on the bus at first?
The initial number of people on the bus was 39.
To find out how many people were on the bus initially, we can work backwards from the given information. If 22 people got off the bus and 17 people remained on the bus, we can assume that the total number of people who got off and those who remained accounts for the entire initial number of people on the bus.
Let's denote the initial number of people on the bus as 'x'. According to the information provided, 22 people got off the bus, so the number of people who remained on the bus is 'x - 22'. We are also given that 17 people remained on the bus, so we can set up the equation:
x - 22 = 17
To solve this equation, we can add 22 to both sides:
x - 22 + 22 = 17 + 22
This simplifies to:
x = 39

An aquarium tank holds 285 liters of water. How much is this in gallons? Use the following conversion: 1 gallon is 3.8 liters.
Suppose that 12 inches of wire costs 72cents.
At the same rate, how much (in cents) will 9 inches of wire cost?
9 inches of wire will cost 54 cents.
To convert liters to gallons, we'll use the given conversion rate:
1 gallon is equal to 3.8 liters.
To find the number of gallons in 285 liters, we divide 285 by 3.8:
285 liters / 3.8 liters per gallon = 75 gallons
Therefore, 285 liters is equal to 75 gallons.
Now, let's calculate the cost of 9 inches of wire using the given rate of 12 inches costing 72 cents.
The cost per inch of wire can be found by dividing 72 cents by 12 inches:
72 cents / 12 inches = 6 cents per inch
To find the cost of 9 inches of wire, we multiply the cost per inch by 9:
6 cents per inch * 9 inches = 54 cents

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.

How to find the new vertices?For a point (x, y), a rotation of 90° counterclockwise changes a quadrant, and changes the coordinates to (-y, x)
So, for the point (-1, 4) which is on the second quadrant, it will move it to the third quadrant, so the new point is (-4, -1)
For the second point:
(-1, 0)
It is on the second quadrant, and we go to the third one again, the new point is (0, -1)
Finally_
(-3, 4) --> (-4, -3)
Then the correct option is the third option.

Marama is planting a rectangular garden in her backyard. She is planning to fence the garden with 28 feet of wired fencing. The garden's area can be represented by the function A(t) = -t2+ 14t where t is the length of a side. What are all of the appropriate values of the domain for the graph of this function? Explain your answer in terms of the situation. Use words, numbers, and/or pictures to show your work.
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):

Which set of values could be the side length of a 30 60 90 triangle? A. {5,5v3,10}
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.
