Answer:

42 feet

Step-by-step explanation:

Since they are similar, that means the rectangles are reduced copies of each other. So, to find the length, you have to do 60/(40/28), to get the length of the pool. 40/28 is the ratio. 60/(40/28) = 42, so the answer is 42 feet.

Answer: 42 feet

Step-by-step explanation:

Width of pool to patio = 28 : 40

28 : 40 = 7 : 10

Multiply both sides by 6:

42 : 60, so the length of the pool is 42 feet

Answer:

28.8 days

Step-by-step explanation:

If. 15 scout = 24 days

than. 18 scout = ?

= 18/15 × 24 days

= 432/15

= 28.8 days.

If 15 scout can sell all their troops cookie's in 24 days than 18 scout too will sell cookies in 28.8 days.

The system of equations 2x + 3y = 4 and 6x + 27y = 12 has infinite solutions when the coefficients of x and y are the same ratio on both equations,

2x + 3y = 4

6x + 27y = 12

For the system of equations to have infinite solutions, the ratio of the coefficients of x and y must be the same. In this case, the ratio of the coefficients of x is 2/6 = 1/3 and the ratio of the coefficients of y is 3/27 = 1/9. Since the ratio of the coefficients is not the same, the system of equations does not have infinite solutions.

Hence, the value of k for which the system of equations 2x + 3y = 4 and 6x + 27y = 12 has infinite solutions is not exist.

The locations (0, 17) and are traversed by an exponential function of the type y = abx, where a and b are constants (2, 153). We can utilise these points to solve for the values of a and b in order to determine the equation of the exponential function.

Since we now know that y = abx when x = 0, we can change the first point to read as follows:

17 = a(b^0)

We can simplify this to: since anything raised to the power of 0 is 1,

17 = a

We can now determine b using the second point (2, 153):

153 = ab^2

By applying the formula:

153/a = b^2

taking square root

b = sqrt(153/a)

Substitute a = 17

b = sqrt(153/17)

The equation will now look like this when we add the value of a back in:

y = a * b^x

y = 17 * sqrt(153/17)^x

y = 17 * sqrt(9)^x

Consequently ,y = 17 * 3^x, is the exponential function that passes between the positions (0, 17) and (2, 153).

Therefore , the exponential function is y = 17 * 3^x .

The distance between points B and C is 10.3 miles.

Trigonometry is the study of angles and the angular relationships of planar and three-dimensional figures. Trigonometry is made up of trigonometric functions (also known as circular functions) such as cosecant, cosine, cotangent, secant, sine, and tangent.

If we have a triangle with a right angle,

Then, tan = Opposite/Adjacent side

To find the distance,

In the ABC right angle triangle,

5.7 miles on the adjacent side = AB

θ = 61°

We must locate the BC.

tan = Opposite/Adjacent side

tan61°= BC/5.7

BC = 5.7×tan61°

To be a function, each x-value (or input) can only be used once.  Each x-value (or input) can only be paired with a single y-value (or output).

The inverse of an inverse function is the original function.

For example, if a function f(x) has an inverse function g(x) such that f(g(x)) = x and g(f(x)) = x for all x in their respective domains, then the inverse of g(x) is f(x).

This is because when you apply the inverse function twice, it cancels out the effect of the inverse, and leaves you with the original function.

In mathematical notation, if f^-1(x) is the inverse of f(x), then (f^-1)^-1(x) = f(x)

So the inverse of an inverse is the original function, which means that (f^-1)^-1 = f

It's also worth noting that any function and its inverse are always one-to-one function, meaning that each element of the domain of the function corresponds to exactly one element of the range and vice-versa, which makes it possible to define an inverse function.

When the rectangular garden has a length of 20 yards and a width of 42 yards the diagonal path will be [tex]\sqrt{2164}[/tex] .

Pythagoras theorem states that “In a right-angled triangle,  the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°. The sides of a right triangle (say a, b and c) which have positive integer values, when squared, are put into an equation, also called a Pythagorean triple.

Since we have a right-angled triangle, we can use the Pythagorean Theorem to find our answer. The Pythagorean Theorem states the following:

[tex]a^{2} +b^{2} =c^{2}[/tex]

In this formula a and b represent the legs of the triangle and c represents the length of the hypotenuse.

Let's substitute our data from the question.

[tex]42^{2} +20^{2} =c^{2}[/tex]

Square.

1764 + 400 = [tex]c^{2}[/tex]

And finally take the root of both sides. We only need to use the positive solution, since the length of the hypotenuse can't be negative.

[tex]c = \sqrt{2164}[/tex]

Answer: 53

Step-by-step explanation:

The length and width of the garden represent the legs of a right triangle, and the diagonal path represents the hypotenuse.

The Pythagorean Theorem states that a squared plus b squared equals c squared, where a and b are the lengths of the legs of a right triangle and c is the length of the hypotenuse.

Let p equal the length of the diagonal path in yards.

Applying the Pythagorean Theorem gives us p squared equals forty-five squared plus twenty-eight squared.

Now square forty-five and twenty-eight to get p squared equals two thousand twenty-five plus seven hundred eighty-four.

Next, find the sum of two thousand twenty-five and seven hundred eighty-four, which is two thousand eight hundred nine.

Finally, calculate the square root of two thousand eight hundred nine to find that p equals fifty-three.

So the length of the diagonal path is fifty-three yards.

The time to complete one swing or period is 16.4 seconds and the length is 3.3 meters

From the question, we have the following parameters that can be used in our computation:

L = 67 meters and g = 9.81 m/s²

The time, t, in seconds, that it takes for one swing or period of the pendulum can be modeled by the equation:

t = 2π(√(L/g))

Substitute the known values in the above equation, so, we have the following representation

t = 2π(√(67/9.81))

Evaluate

t = 16.4 seconds (approx)

Here, we use the same equation and solve for L

In this case, t = 9.6

t = 2π(√(L/g))

substitute the known values in the above equation, so, we have the following representation

9.6 = 2π(√(L/9.81))

So, we have

L = (9.6/(2π))² * 9.81

The solutions to the equation are x = 2.61 and x = -0.61

To solve the quadratic equation 3x² - 16x + 6 = 0, we'll use the quadratic formula:

x = (-b ± √(b²-4ac)) / 2a

Where a = 3, b = -16 and c = 6.

x = (-(-16) ± √((-16)²-4(3)(6)))/2(3)

x = 16 ± √(256-72) / 6

x = 16 ± √(184) / 6

x = 16 ± √184 / 6

x = (16 ± 4√23) / 6

So the solutions are:

x = (16 + 4√23) / 6 ≈ 2. 61 or x = (16 - 4√23) / 6 ≈ -0.61

Therefore, the solutions to the equation are x = 2.61 and x = -0.61.

The Factor analysis is a statistical method for analyzing the intercorrelations among various measures or test scores.

Factor analysis is a technique used to reduce a large number of variables to a smaller number of factors. This technique extracts the maximum common variance from all variables and puts them into the common score. This score can be used for further analysis as an index for all variables. A "factor" is a set of observed variables with similar response patterns. These are associated with hidden variables that are not directly measured (called noise variables). Factors are listed by their factor loadings, or the amount of variation in the data they can explain. There are two types: exploratory and confirmatory.

The height of Tree A t years after being planted can be represented by the equation:

A = 30 + 2t

This equation states that the initial height of the tree (30 inches) plus the annual growth of the tree (2 inches per year) multiplied by the number of years that have passed (t) will give the current height of the tree.

The height of Tree B t years after being planted can be represented by the equation:

B = 15 + 5t
