Use long division to find the quotient Q(x) and the remainder R(x) when P(x) is divided by d(x) and express P(x) in the for

lilavasa [31]

Answer:

$P(x)=(x+9)(x^2-7x+52)+3$

Step-by-step explanation:

We are given that

$P(x)=x^3+2x^2-11x+471$

$d(x)=x+9$

We have to find the value of Q(x) and Remainder R(x).

Quotient, $Q(x)=x^2-7x+52$

Remainder, $R(x)=3$

We know that

$Dividend=Divisor\times Quotient+Remainder$

$P(x)=(x+9)(x^2-7x+52)+3$

Compare square root of one hundred eighty and one hundred two eighths using <, >, or =.

olga2289 [7]

Converting the mixed number to a decimal, the correct comparison of the numbers is given as follows:

$\sqrt{180} > \sqrt{100 \frac{2}{8}}$

<h3>What is a mixed number?</h3>

A mixed number is represented by an integer part and a fractional part, as follows:

a b/c.

In which:

a is the integer part.

b/c is the fractional part.

In this problem, the numbers are given as follows:

$\sqrt{180}, \sqrt{100 \frac{2}{8}}$

The mixed number is:

100 and 2/8 = 100 + 0.25 = 100.25.

The square root is an increasing function, hence the higher the input, the higher the square root, as 180 > 100 the comparison is:

$\sqrt{180} > \sqrt{100 \frac{2}{8}}$
