Write the form of the partial fraction decomposition of the rational expression. Do not solve for the constants. 5x − 4 x(x2 + 7
Nikitich [7]

Answer:

\frac{5x-4}{x(x^2+7)^2}  = \frac{A}{x} + \frac{Bx+C}{x^2+7} + \frac{Dx+E}{(x^2+7)^2}

Step-by-step explanation:

Given the expression \frac{5x-4}{x(x^2+7)^2}, we are to re-write the expression in form of a partial fraction.

Before we write in form of a partial fraction, we need to note the expression at the denominator. <u>Since the expression in parenthesis is a quadratic equation, the equivalent numerator must be a linear expression.</u>

<u />

<u>Also the quadratic equation is a repeated form since it is squared</u>. This means that we are to repeat the quadratic equation twice when writing as a partial fraction.

\frac{5x-4}{x(x^2+7)^2}  = \frac{A}{x} + \frac{Bx+C}{x^2+7} + \frac{Dx+E}{(x^2+7)^2}

From the above partial fraction, <em>it can be seen that x² + 7 in parenthesis was repeated twice and their equivalent expressions at the numerator are  both linear i.e Bx+E and Dx+ E where A, B, C, D and E are the unknown constant.</em>

How do you categorize each of these questions as one of these types
Sindrei [870]

The statistical questions are:

  • On average, how many books does each person in the United States read each year
  • Which book was read most by students in the class, this summer

The non-statistical questions are:

  • How many acts are there in the play Romeo and Juliet
  • How many books are in the class right not

<h3>How to categorize the questions?</h3>

As a general rule, questions whose answers can be determined using a single data point are non-statistical questions.

Using the above rule, we have the non-statistical questions to be:

  • How many acts are there in the play Romeo and Juliet
  • How many books are in the class right not

As a general rule, questions whose answers cannot be determined using a single data point are statistical questions.

Using the above rule, we have the statistical questions to be:

  • On average, how many books does each person in the United States read each year
  • Which book was read most by students in the class, this summer

Also, both statistical questions are numerical
