Find the partial fraction decomposition of x-3/x(x^2+3)
Setler [38]

Answer:

-1 / x + (x + 1) / (x² + 3)

Step-by-step explanation:

(x − 3) / (x (x² + 3))

There are two factors in the denominator, so split this into two fractions with unknown numerators:

A / x + (Bx + C) / (x² + 3)

Combine back into one fraction:

(A (x² + 3) + (Bx + C) x) / (x (x² + 3))

Now equate this numerator with the original:

A (x² + 3) + (Bx + C) x = x − 3

Ax² + 3A + Bx² + Cx = x − 3

(A + B) x² + Cx + 3A = x − 3

Match the coefficients:

A + B = 0

C = 1

3A = -3

Solve:

A = -1

B = 1

C = 1

Therefore, the partial fraction decomposition is:

-1 / x + (x + 1) / (x² + 3)

Here's a graph showing that the two are the same:

Help please!<br> I need ur help please!
Anna35 [415]

Answer:

plugging in the fractions into a calculator would make this super easy

Step-by-step explanation:

5/6 = six divided by five, right? okay so just that down and solve it

Fractions are just a number divided by another number to get a percentage

Think about 1/2, thats 50 percent right? Its half of something

So yeah, you just gotta divide both sides and see which number is bigger, for example

5/6= 0.833

and

3/8= 0.375

So which number is bigger? 0.83 is bigger of course sooooo

5/6 > 3/8

Find the sum of 997 + 992 + 987 +...+ 257 +252
Vikentia [17]

Answer:

  93,675

Step-by-step explanation:

We see that the given sequence is an arithmetic sequence with first term 997, common difference -5, and last term 252.

The number of terms in the sequence (n) can be found from the formula for the n-th term:

  an = a1 +d(n -1)

  (an -an)/d +1 = n

  (252 -997)/(-5) +1 = n = 150

The sum of these terms is the average of the first and last terms, multiplied by the number of terms:

  S150 = (997 +252)/2·150 = 93,675

The sequence sum is 93,675.

If 20 is 40% of a value, what is that value?
podryga [215]
50 is the value cause 20 is 40 of the percent, 20+20 is 40 now you made it into 80%.20% is remaining so add 10.
