Divide f(x) by d(x), and write a summary statement in the form indicated.
Mandarinka [93]

Answer:

The correct option is B)  f(x) =(x^2+1)(x^2+4x+5)

Step-by-step explanation:

Consider the provided function.

f(x) = x^4 + 4x^3 + 6x^2 + 4x + 5 and d(x) = x^2+1

We need to divide f(x) by d(x)

As we know: Dividend = Divisor × Quotient + Remainder

In the above function f(x) is dividend and divisor is d(x)

Divide the leading term of the dividend by the leading term of the divisor:\frac{x^4}{x^2}=x^2

Write the calculated result in upper part of the table.

Multiply it by the divisor: x^2(x^2+1)=x^4+x^2

Now Subtract the dividend from the obtained result:

(x^4 + 4x^3 + 6x^2 + 4x + 5)-(x^4-x^2)=4x^3+5x^2+4x+5

Again divide the leading term of the obtained remainder by the leading term of the divisor: \frac{4x^3}{x^2}=4x

Write the calculated result in upper part of the table.

Multiply it by the divisor: 4x(x^2+1)=4x^3+4x

Subtract the dividend:

(4x^3+5x^2+4x+5)-(4x^3+4x)=5x^2+5

Divide the leading term of the obtained remainder by the leading term of the divisor: \frac{5x^2}{x^2}=5

Multiply it by the divisor: 5(x^2+1)=5x^2+5

Subtract the dividend:

(5x^2+5)-(5x^2+5)=0

Therefore,

Dividend = x^4 + 4x^3 + 6x^2 + 4x + 5

Divisor = x^2+1

Quotient = x^2+4x+5

Remainder = 0

Dividend = Divisor × Quotient + Remainder

f(x) = (x^2+1)(x^2+4x+5)

Hence, the correct option is B)  f(x) =(x^2+1)(x^2+4x+5)

A 16 1/2 kilometer stretch of road needs repairs. Workers can repair 2 1/4 kilometer of road per week. How many weeks will take
liraira [26]

Answer:

7\frac{1}{3}\ weeks

Step-by-step explanation:

we know that

To find out how many weeks it will take to repair this stretch of road, divide the total length of the road by the workers' rate

so

\frac{16\frac{1}{2}}{2\frac{1}{4}}

Convert mixed number to an improper fraction

16\frac{1}{2}\ km=\frac{16*2+1}{2}=\frac{33}{2}\ km

2\frac{1}{4}\ km=\frac{2*4+1}{4}=\frac{9}{4}\ km/week

substitute

(33/2)/(9/4)=\frac{132}{18}\ weeks

Convert to mixed number

\frac{132}{18}\ weeks=\frac{126}{18}+\frac{6}{18}=7\frac{1}{3}\ weeks
