what is the partial-fraction expansion of the rational function f(s)=7s2+30s+27s3+9s?
The partial fraction expansion of the rational function
f(s) = 7s²+30s+27s/3+9s is 7s/9 - 164/81s + 27 + 164/27
In math the term partial fraction is defined as a method that is used to split the complicated fraction into a simpler form.
Here we have given the rational function f(s) = 7s²+30s+27s/3+9s.
And we have to find the partial fraction expansion for the function.
While we looking into the given rational function, for the given function we have to perform the partial fraction decomposition of
=> f(s) = 7s²+30s+27s/3+9s.
And it can be simplified as,
=> f(s) = 7s²+57s/3+9s.
Take s as common on the numerator, then we get
=> f(s) = s(7s + 57) / 3 + 9s
Since the degree of the numerator is not less than degree of the denominator, perform synthetic division, then we get the result as
=> f(s) = 7s/9 + 164/27 + [-164/9]/9s + 3
When we further simplify this expression, then we get,
=> f(s) = 7s/9 + 164/27 - 164/81s + 27

I think of a number, double it, then subtract 7. The result is 10.
Find the number.
Answer:
17/2
Step-by-step explanation:
Work backwards. you have 10, then opposite of subtract 7 is add 7 which gives you 17. then opposite of double is half getting you 8.5 or 17/2
Answer:
Your number is 8.5 or 17/2
Step-by-step explanation:
Let's say your number is equal to the variable n.
Then we can set up an equation for this scenario: 2n - 7 = 10
Now, we need to use algebra to solve:
2n - 7 = 10 → add 7 to both sides
2n = 17 → divide both sides by 2
n = 17/2 = 8.5
Thus, the number you were thinking of was 8.5, or 17/2
What are the roots of quadratic equation x 5 )( x 2 )= 0 *?
The roots of the quadratic equation x^5 - x^2 = 0 are x = 0 and x = ±√2, which can be found by factoring and setting each factor equal to 0. The quadratic can be factored into (x^2)(x^3 - 1) = 0 and then the factors can be set equal to 0, resulting in x = 0 and x = ±√2.
To find the roots of the quadratic equation x^5 - x^2 = 0, first we must factor the equation. To do this, we can recognize that there are two terms, x^5 and x^2, and that the exponents are both greater than 1, so we can factor out an x^2 from both terms. When we do this, we get (x^2)(x^3 - 1) = 0. Now we can set each factor equal to 0, so that x^2 = 0 and x^3 - 1 = 0. Solving for x in the first equation, we get x = 0. To solve for x in the second equation, we can add 1 to both sides, so that x^3 = 1. Taking the cube root of both sides, we get x = ±√2. Therefore, the roots of the quadratic equation x^5 - x^2 = 0 are x = 0 and x = ±√2.
x^5 - x^2 = 0
x^2(x^3 - 1) = 0
x^2 = 0 → x = 0
x^3 - 1 = 0 → x^3 = 1 → x = ±√2

The ratio of milk to water in the mixture is 12:5, which means that for every 12 parts of milk, there are 5 parts of water. We can set up a proportion to solve for the amount of milk in the mixture. Let's call the amount of milk x.Then the proportion is:(12 parts milk) / (5 parts water) = (x liters milk) / (144 liters water)To solve for x, we can cross-multiply and simplify:12x = 5 * 144
x = (5 * 144) / 12
x = 60 litersThus, the amount of milk in the mixture is 60 liters.
According to the question,
ratio amount of water : milk is 5:12
given amount of water in the mixture is 144 litre,

Are AAA triangles solvable?
Yes, they are solvable.
In geometry, a triangle is considered to be an "AAA" triangle (or "AAA similarity") if all three of its angles are equal. Such a triangle is also known as an equilateral triangle.
An equilateral triangle is a type of triangle that has all three sides of equal length and all three angles of equal measure (60 degrees). It is a regular polygon, and it is one of the few geometric shapes that has this property.
Because all three angles in an equilateral triangle are equal, it is relatively easy to solve for various properties of the triangle. For example, the length of each side can be found if the measure of one angle and the length of one side are known. Similarly, the measure of an angle can be found if the length of one side and the measure of one angle are known.
In summary, AAA triangles are solvable because they have a consistent and predictable structure, with all sides and angles being equal.

the equation of a line is y equals 4 over 3 x minus 5 over 3. what would be the slope of a line perpendicular to this line?
The slope of the line perpendicular to the given line is calculated by taking the negative reciprocal of the given slope.The slope of the given line is 4/3. The slope of the line perpendicular to the given line is -3/4.
To find the slope of a line perpendicular to the given line, we need to take the negative reciprocal of the slope of the given line. The equation of the given line is y = 4/3x - 5/3. To calculate the slope, we need to rearrange the equation to the form y = mx + b, where m is the slope and b is the y-intercept. Rearranging the equation to the form y = mx + b, we get y = 4/3x - 5/3 which can be written as 4/3x - y = 5/3. The slope of the given line is 4/3. To find the slope of the line perpendicular to the given line, we take the negative reciprocal of 4/3 which is -3/4. Therefore, the slope of the line perpendicular to the given line is -3/4.

x-y+2z=9
3x+y=z=2
2x-y+z=8
Answer:
x=8/7, y=-25/7, z=15/7
Step-by-step explanation:
x-y+2z=9 ==> equation 1
3x+y=z=2 ==> equation 2
2x-y+z=8 ==> equation 3
3x+y+z=2
+ (2x-y+z=8)
3x+2x + y+(-y) + z+z = 2+8 ==> add equation 2 and 3 to eliminate y
5x + 2z = 10 ==> equation 4
x-y+2z=9
- (2x-y+z=8)
x - 2x + (-y)-(-y) + 2z-z = 9-8 ==> subtract equation 1 and 3 to eliminate y
-x + 0 + z = 1 ==> Let's say -y=a. (-y)-(-y) = a-a = 0.
(-x + z = 1)*2 ==> multiply by 2 to get z to become 2z
-2x + 2z = 2 ==> equation 5
5x + 2z = 10
- (-2x + 2z = 2)
5x-(-2x) + 2z-2z = 10-2 ==> subtract equation 4 and 5 to solve for x
5x+2x = 8
7x = 8 ==> divide both sides by 7 to isolate x
x = 8/7
-2(8/7) + 2z = 2 ==> plugin x into equation 5 to solve for z
-16/7 + 2z = 2 ==> simplify
(-16/7 + 2z = 2)*7 ==> multiply the equation by 7 to eliminate fractions
-16 + 14z = 14
14z = 30 ==> add 16 on both sides to isolate z
z = 30/14 ==> divide each side by 14
z = 15/7 ==> simplify
2(8/7)-y+(15/7)=8 ==> plugin x = 8/7 and z = 15/7 into equation 3
16/7 - y + 15/7 = 8
(16/7 + 15/7 - y = 8)*7 ==> multiply the equation by 7 to remove fractions
16 + 15 - 7y = 56
31 - 7y = 56
-7y = 25 ==> subtract 31 on both sides to isolate y
7y = -25
y = -25/7

Juan Vance Weekly salary: $231.67
Not self-employed
Find the annual amount of FICA at 7.51% by computing his annual salary
The annual income of Juan Vance is $12,955.17.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
In order to pay for Social Security and Medicare, the Federal Insurance Contributions Act(FICA) mandates payroll deductions from both employers and employees.
Given, Juan Vance's Weekly salary is $231.67.
∴ Annually Juan earns $(52×231.67) = $12,046.84.
FICA deducts 7.51% from it and then combines another 7.51% with the employee,
∴ The net annual income of Juan Vence is
= [{12046.84 - (7.51/100)×12046.84 + {(7.51 + 7.51)/100}×12046.84}]

Find (x^4 − 5x^3 + 17x + 3) divided
by (x − 3).
Answer:
the division of (x^4 − 5x^3 + 17x + 3) by (x − 3) is equal to x^3 - 3x^2 + 4x - 3, with a remainder of 0.
Step-by-step explanation:
To divide (x^4 − 5x^3 + 17x + 3) by (x − 3), we can use polynomial long division. This involves dividing the polynomial by the divisor (x - 3) and expressing the result as a quotient plus a remainder. The remainder will be a polynomial of degree less than the degree of the divisor.
Here is how the division would look:
x -3 x^4 -5x^3 17x 3
--- ----- ---- ----- --- ---
x -3 x^3 -5x^2 17 0
x^3 -3x^2 -2x^2 3
0 -2x^2 -2x^2 0
0 0 -4x^2 3
0 0 -4x^2 -9
0 0 0 -9
0 0 0 0
From this division, we can see that the quotient is x^3 - 3x^2 + 4x - 3, and the remainder is 0. Therefore, we can express the division as:
(x^4 − 5x^3 + 17x + 3) / (x − 3) = (x^3 - 3x^2 + 4x - 3) + 0
This means that the division of (x^4 − 5x^3 + 17x + 3) by (x − 3) is equal to x^3 - 3x^2 + 4x - 3, with a remainder of 0.
Given equation= (x^4 - 5 x^3 + 17 x + 3)/(x - 3)
