The sum of the given equation is 7[tex]\sqrt[5]{x^{2} y}[/tex].
What is fractional equation?A fractional equation is one in which one or more of its terms have the unknown as their denominator. Equations involving fractions can be resolved using the Cross-Product property.Therefore, when we reduce or simplify a fraction, we aim for maximum simplicity. In order to do this, we divide both the numerator and the denominator by the biggest integer that can be divided precisely into both numbers. In other words, we choose the greatest number that the top and bottom have in common and divide them by that.Equations using fractions require the solution of equations in which the unknown variable is a component of the fraction's numerator or denominator. To solve fractional equations, we must determine the value of the undetermined variable.Given data :

A certain forest covers an area of 4000 km². Suppose that each year this area decreases by 4.25%. What will the area be after 15 years?
Answers
The area of the forest after 15 years will be 2189.4
What is an area?The area is the region bounded by the shape of an object. The space covered by the figure or any two-dimensional geometric shape, in a plane, is the area of the shape.
i = The initial area of the forest = 4200km
r = Per year decrease is = 4.25%
n = Number of years = 15
The required formula is
The area of forest will be
A = i (1-r)^n
A = 4200(1-0.425)^15
A= 2189.4

Tides The length of time between consecutive high tides is 12 hours and 25 minutes. According to the National Oceanic and Atmospheric Administration, on Saturday, April 26, 2014, in Charleston, South Carolina, high tide occurred at 6:30 am (6.5 hours) and low tide occurred at 12:24 pm (12.4 hours). Water heights are measured as the amounts above or below the mean lower low water. The height of the water at high tide was 5.86 feet, and the height of the water at low tide was − 0.38 foot.
(a) Approximately when will the next high tide occur?
(b) Find a sinusoidal function of the form
y = A sin(ωx – ϕ) + B
that models the data.
(c) Use the function found in part (b) to predict the height of the water at 3 pm on April 26, 2014.
Answers
Answer:
(a) The next tide will occur at 6:55pm
(b) [tex]y = 3.12 \cos(\frac{24\pi}{149}(x - 6.5)) + 2.74[/tex]
(c) The height is: 2.904ft
Step-by-step explanation:
Given
[tex]T_1 = 12hr:25min[/tex] --- difference between high tides'
Solving (a): The next time a high tide will occur
From the question, we have that:
[tex]High =6:30am[/tex] --- The time a high tide occur
The next time it will occur is the sum of High and T1
i.e.
[tex]Next = High + T_1[/tex]
[tex]Next = 6:30am + 12hr : 25min[/tex]
Add the minutes
[tex]Next = 6:55am + 12hr[/tex]
Add the hours
[tex]Next = 6:55pm[/tex]
Solving (b): The sinusoidal function
Given
[tex]High\ Tide = 5.86[/tex]
[tex]Low\ Tide = -0.38[/tex]
[tex]T = 12hr:25min[/tex] -- difference between consecutive tides
[tex]Shift = 6.5hr[/tex]
The sinusoidal function is represented as:
[tex]y = A\cos(w(x - C)) + B[/tex]
Where
[tex]A = Amplitude[/tex]
[tex]A = \frac{1}{2}(High\ Tide - Low\ Tide)[/tex]
[tex]A = \frac{1}{2}(5.86 - -0.38)[/tex]
[tex]A = \frac{1}{2}(6.24)[/tex]
[tex]A = 3.12[/tex]
[tex]B = Mean[/tex]
[tex]B = \frac{1}{2}(High\ Tide + Low\ Tide)[/tex]
[tex]B = \frac{1}{2}(5.86 - 0.38)[/tex]
[tex]B = \frac{1}{2}(5.48)[/tex]
[tex]B = 2.74[/tex]
[tex]w = Period[/tex]
[tex]w = \frac{2\pi}{T}[/tex]
[tex]w = \frac{2\pi}{12:25}[/tex]
Convert to hours
[tex]w = \frac{2\pi}{12\frac{25}{60}}[/tex]
Simplify
[tex]w = \frac{2\pi}{12\frac{5}{12}}[/tex]
As improper fraction
[tex]w = \frac{2\pi}{\frac{149}{12}}[/tex]
Rewrite as:
[tex]w = \frac{2\pi*12}{149}[/tex]
[tex]w = \frac{24\pi}{149}[/tex]
[tex]C = shift[/tex]
[tex]C=6.5[/tex]
So, we have:
[tex]y = A\cos(w(x - C)) + B[/tex]
[tex]y = 3.12 \cos(\frac{24\pi}{149}(x - 6.5)) + 2.74[/tex]
Solving (c): The height at 3pm
At 3pm, the value of x is:
[tex]x=3:00pm - 6:30am[/tex]
[tex]x=9.5hrs[/tex]
So, we have:
[tex]y = 3.12 \cos(\frac{24\pi}{149}(x - 6.5)) + 2.74[/tex]
[tex]y = 3.12 \cos(\frac{24\pi}{149}(9.5 - 6.5)) + 2.74[/tex]
[tex]y = 3.12 \cos(\frac{24\pi}{149}(3)) + 2.74[/tex]
[tex]y = 3.12 \cos(\frac{72\pi}{149}) + 2.74[/tex]
[tex]y = 3.12 *0.0527 + 2.74[/tex]
[tex]y = 2.904ft[/tex]

The perimeter of a rectangle is 64 feet. The length is two more than double the
width. Find the dimensions of the rectangle.
(Remember Perimeter of rectangle = 2L+ 2w)
Answers
Answer:
To solve this problem, we can set up the following equation:
2L + 2W = 64
We are told that the length of the rectangle is two more than double the width, so we can write the following equation:
L = 2W + 2
Substituting this equation into the first equation, we get:
2(2W + 2) + 2W = 64
Simplifying this equation, we get:
6W + 4 = 64
Subtracting 4 from both sides, we get:
6W = 60
Dividing both sides by 6, we get:
W = 10
The width of the rectangle is 10 feet.
To find the length of the rectangle, we can substitute this value back into the equation L = 2W + 2 to get:
L = 2(10) + 2
= 20 + 2
= 22
The length of the rectangle is 22 feet.
Therefore, the dimensions of the rectangle are 10 feet by 22 feet.
Step-by-step explanation:
Length = 22
Explanation
1. Write the equation L= 2w + 2 for the given statement length = two more than doubled word.
2. 2(2w+2) represents 2L in the perimeter equation. Solve 2(2w+2) + 2w = 64 to find the value of the width.
3. Distribute the 2 into the parentheses first, which should give you 4w + 4 + 2w = 64.
4. Combine like terms 4w and 2w leaving you 6w + 4 = 64.
5. Subtract 4 on both sides of the equation to get 6w alone. 6w = 60.
6. Divide by 6 on both sides to solve for w. w = 10.
7. Input x = 10 into 2w + 2 to find the length of the rectangle. 2(10) + 2 = l
8, multiply 2 by 10, which is 20. Add that to 2, which is 22.

What is the test statistic
Answers
Answer:
[tex]t = 31.29[/tex]
Step-by-step explanation:
Given
[tex]\begin{array}{ccccccc}{Stick} & {25.8} & {26.9} & {26.2} & {25.3} & {26.7}& {26.1} \ \\ {Liquid} & {16.9} & {17.4} & {16.8} & {16.2} & {17.3}& {16.8} \ \end{array}[/tex]
Required
Determine the test statistic
Let the dataset of stick be A and Liquid be B.
We start by calculating the mean of each dataset;
[tex]\bar x =\frac{\sum x}{n}[/tex]
n, in both datasets in 6
For A
[tex]\bar x_A =\frac{25.8+26.9+26.2+25.3+26.7+26.1}{6}[/tex]
[tex]\bar x_A =\frac{157}{6}[/tex]
[tex]\bar x_A =26.17[/tex]
For B
[tex]\bar x_B =\frac{16.9+17.4+16.8+16.2+17.3+16.8}{6}[/tex]
[tex]\bar x_B =\frac{101.4}{6}[/tex]
[tex]\bar x_B =16.9[/tex]
Next, calculate the sample standard deviation
This is calculated using:
[tex]s = \sqrt{\frac{\sum(x - \bar x)^2}{n-1}}[/tex]
For A
[tex]s_A = \sqrt{\frac{\sum(x - \bar x_A)^2}{n-1}}[/tex]
[tex]s_A = \sqrt{\frac{(25.8-26.17)^2+(26.9-26.17)^2+(26.2-26.17)^2+(25.3-26.17)^2+(26.7-26.17)^2+(26.1-26.17)^2}{6-1}}[/tex]
[tex]s_A = \sqrt{\frac{1.7134}{5}}[/tex]
[tex]s_A = \sqrt{0.34268}[/tex]
[tex]s_A = 0.5854[/tex]
For B
[tex]s_B = \sqrt{\frac{\sum(x - \bar x_B)^2}{n-1}}[/tex]
[tex]s_B = \sqrt{\frac{(16.9 - 16.9)^2+(17.4- 16.9)^2+(16.8- 16.9)^2+(16.2- 16.9)^2+(17.3- 16.9)^2+(16.8- 16.9)^2}{6-1}}[/tex]
[tex]s_B = \sqrt{\frac{0.92}{5}}[/tex]
[tex]s_B = \sqrt{0.184}[/tex]
[tex]s_B = 0.4290[/tex]
Calculate the pooled variance
[tex]S_p^2 = \frac{(n_A - 1)*s_A^2 + (n_B - 1)*s_B^2}{(n_A+n_B-2)}[/tex]
[tex]S_p^2 = \frac{(6 - 1)*0.5854^2 + (6 - 1)*0.4290^2}{(6+6-2)}[/tex]
[tex]S_p^2 = \frac{2.6336708}{10}[/tex]
[tex]S_p^2 = 0.2634[/tex]
Lastly, calculate the test statistic using:
[tex]t = \frac{(\bar x_A - \bar x_B) - (\mu_A - \mu_B)}{\sqrt{S_p^2/n_A +S_p^2/n_B}}[/tex]
We set
[tex]\mu_A = \mu_B[/tex]
So, we have:
[tex]t = \frac{(\bar x_A - \bar x_B) - (\mu_A - \mu_A)}{\sqrt{S_p^2/n_A +S_p^2/n_B}}[/tex]
[tex]t = \frac{(\bar x_A - \bar x_B) }{\sqrt{S_p^2/n_A +S_p^2/n_B}}[/tex]
The equation becomes
[tex]t = \frac{(26.17 - 16.9) }{\sqrt{0.2634/6 +0.2634/6}}[/tex]
[tex]t = \frac{9.27}{\sqrt{0.0878}}[/tex]
[tex]t = \frac{9.27}{0.2963}[/tex]
[tex]t = 31.29[/tex]
The test statistic is 31.29

The previous sentence, where y and x are variables, is commonly referred to as a "linear equation in two variables." Bivariate linear equations are those that contain two variables in them. The linear equations 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3 are examples.

What is permutation?Basically A permutation is an arrangement of items in a specific direction or sequence. One should consider both the selection and the arrangement while dealing with permutation. In permutations, ordering is crucially important. The permutation is seen as an ordered combination, in other words.
Given 1,214
since there are 4 places in the digit,
so 4 values less than 10 can be solved by
9, 8, 7, and 6
so by permutation to find ⁹P₄ = 9!/(9 - 4)!
= (9 x 8 x 7 x 6 x5!)/5!
⁹P₄ = 3,024
Hence there are 3,024 different ways.
