Resolve the expression <img src="https://tex.z-dn.net/?f=%5Cfrac%7B%28x-2%29%7D%7B%28x%5E%7B2%7D%20%2B1%29%28x-1%29%5E%7B2%7D%20

The partial fraction expansion will look like

(<em>x</em> - 2)/((<em>x</em> ² + 1) (<em>x</em> - 1)²) = (<em>ax</em> + <em>b</em>)/(<em>x</em> ² + 1) + <em>c</em>/(<em>x</em> - 1) + <em>d</em>/(<em>x</em> - 1)²

Get everything in terms of a common denominator, and compare the numerators on both sides:

<em>x</em> - 2 = (<em>ax</em> + <em>b</em>) (<em>x</em> - 1)² + <em>c</em> (<em>x</em> ² + 1) (<em>x</em> - 1) + <em>d</em> (<em>x</em> ² + 1)

Expand the right side:

<em>x</em> - 2 = (<em>ax</em> + <em>b</em>) (<em>x</em> - 1)² + <em>c</em> (<em>x</em> ² + 1) (<em>x</em> - 1) + <em>d</em> (<em>x</em> ² + 1)

<em>x</em> - 2 = (<em>a</em> + <em>c</em>) <em>x</em> ³ + (-2<em>a</em> + <em>b</em> - <em>c</em> + <em>d</em>) <em>x</em> ² + (<em>a</em> - 2<em>b</em> + <em>c</em>) <em>x</em> + <em>b</em> - <em>c</em> + <em>d</em>

<em />

Match up the coefficients and solve the resulting system of equations:

<em>a</em> + <em>c</em> = 0

-2<em>a</em> + <em>b</em> - <em>c</em> + <em>d</em> = 0

<em>a</em> - 2<em>b</em> + <em>c</em> = 1

<em>b</em> - <em>c</em> + <em>d</em> = -2

==>   <em>a</em> = -1, <em>b</em> = -1/2, <em>c</em> = 1, <em>d</em> = -1/2

So the expansion into partial fractions is

(<em>x</em> - 2)/((<em>x</em> ² + 1) (<em>x</em> - 1)²) = (-<em>x</em> - 1/2)/(<em>x</em> ² + 1) + 1/(<em>x</em> - 1) - 1/(2 (<em>x</em> - 1)²)

… = -(2<em>x</em> + 1)/(2 (<em>x</em> ² + 1)) + 1/(<em>x</em> - 1) - 1/(2 (<em>x</em> - 1)²)

Which of the following numbers is between 3/5 and 5/7
Vsevolod [243]

Numbers 8/9 and 47/70 are between 3/5 and 5/7

Step-by-step explanation:

  • Step 1: Find the equivalent decimal expressions of all the given fractions to find which ones are between 3/5 and 5/7

3/5 = 0.6 and 5/7 = 0.71

Option 1 ⇒ 1/2 = 0.5

Option 2 ⇒ 3/7 = 0.43

Option 3 ⇒ 8/9 = 0.89

Option 4 ⇒ 19/35 = 0.54

Option 5 ⇒ 47/70 = 0.67

∴ 8/9 and 47/70 lies between 3/5 and 5/7

after two years on the job, an engineer salary was $60,000. after seven years on the job, her salary was $66,000. let y represen
galina1969 [7]

Answer: y = 1200m + 57,600

Step-by-step explanation: To be a line, let's say that x is the numbers of years on the job and y the salary.

So, we have (2,60000) and (7,66000)

y = mx + b

66000 = 7m + b

60000 = 2m + b (-)

________________________

6000 = 5m

m = 6000/5 = 1200

60000 = 2m + b

60000 = 2.1200 + b

60000 = 2400 + b

b = 60000 - 2400

b = 57600

y = mx + b

y = 1200m + 57,600
