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

x² + 6x = 40

This equation has the value of x as 4

Let's test

(4)^2 + 6(4) = 40

So, x is 4 in this equation

Now for the question, what is the value of x-6

We know x is 4

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

Therefore , the  probability that an endure all battery selected at random will last more than 550 hours is 0.0301.

Probabilities can be expressed as proportions with a 0–1 range or as percentages with a 0%–100% range. If an event has a probability of 1, it is very certain to occur; if it has a probability of 0, it has no chance of occurring. There are 45 chances out of 100 that an event will occur when its probability is 0.45 (45%).

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

Answer: (x=8/7, y=15/7, z=-25/7)

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 Median of the following observation set 5 7 10 12 11 will be 10.

One measure of central tendency is the median. The median is the number that lies in the middle of the specified range of integers. It separates the higher half from the lower half of a particular data sample. At least half of the observations are above or equal to the median, and at least half of the observations are below the median.

The median can be calculated as follows when there are odd numbers of observations in a data collection:
