Chapter 7: Problem 2

Give an example of each of the following. a. A simple linear factor b. A repeated linear factor c. A simple irreducible quadratic factor d. A repeated irreducible quadratic factor

Short Answer

Expert verified
Question: Provide an example for each of the following types of factors: a. Simple linear factor b. Repeated linear factor c. Simple irreducible quadratic factor d. Repeated irreducible quadratic factor Answer: a. (2x + 3) b. (x - 4)^2 c. (x^2 + 2x + 2) d. (x^2 + x + 1)^2

Step by step solution

01

a. Simple linear factor

A simple linear factor is a linear expression with a single power and can be represented as \((ax + b)\), where \(a \neq 0\). An example of a simple linear factor is: \((2x + 3)\).
02

b. Repeated linear factor

A repeated linear factor is a linear expression raised to a power greater than 1 and can be represented as \((ax + b)^n\), where \(a \neq 0\) and \(n > 1\). An example of a repeated linear factor is: \((x - 4)^2\).
03

c. Simple irreducible quadratic factor

A simple irreducible quadratic factor is a quadratic expression that cannot be factored any further and can be represented as \((ax^2 + bx + c)\), where \(a \neq 0\) and the discriminant \(b^2 - 4ac < 0\). An example of a simple irreducible quadratic factor is: \((x^2 + 2x + 2)\).
04

d. Repeated irreducible quadratic factor

A repeated irreducible quadratic factor is an irreducible quadratic expression raised to a power greater than 1 and can be represented as \((ax^2 + bx + c)^n\), where \(a \neq 0\), the discriminant \(b^2 - 4ac < 0\), and \(n > 1\). An example of a repeated irreducible quadratic factor is: \((x^2 + x + 1)^2\).

Let \(a>0\) and let \(R\) be the region bounded by the graph of \(y=e^{-a x}\) and the \(x\) -axis on the interval \([b, \infty)\) a. Find \(A(a, b),\) the area of \(R\) as a function of \(a\) and \(b\) b. Find the relationship \(b=g(a)\) such that \(A(a, b)=2\) c. What is the minimum value of \(b\) (call it \(b^{*}\) ) such that when \(b>b^{*}, A(a, b)=2\) for some value of \(a>0 ?\)

\(\pi<\frac{22}{7}\) One of the earliest approximations to \(\pi\) is \(\frac{22}{7} .\) Verify that \(0<\int_{0}^{1} \frac{x^{4}(1-x)^{4}}{1+x^{2}} d x=\frac{22}{7}-\pi .\) Why can you conclude that \(\pi<\frac{22}{7} ?\)

Sociologists model thespread of rumors using logistic equations. The key assumption is that at any given time, a fraction \(y\) of the population, where \(0 \leq y \leq 1,\) knows the rumor, while the remaining fraction \(1-y\) does not. Furthermore, the rumor spreads by interactions between those who know the rumor and those who do not. The number of such interactions is proportional to \(y(1-y) .\) Therefore, the equation that models the spread of the rumor is \(y^{\prime}(t)=k y(1-y)\), where \(k\) is a positive real number. The fraction of people who initially know the rumor is \(y(0)=y_{0},\) where \(0

Find the volume of the described solid of revolution or state that it does not exist. The region bounded by \(f(x)=-\ln x\) and the \(x\) -axis on the interval (0,1] is revolved about the \(x\) -axis.

Given a Midpoint Rule approximation \(M(n)\) and a Trapezoid Rule approximation \(T(n)\) for a continuous function on \([a, b]\) with \(n\) subintervals, show that \(T(2 n)=(T(n)+M(n)) / 2\).
