Divide x ^ 4 + x - 1 by x - 1

vladimir2022 [97]

The required, divide is given by $=x^3+x^2+x+2+\frac{1}{x-1}$

<h3>What is fraction of polynomial?</h3>

Fraction of polynomial is, in the numerator and in the denominator of a fraction there is polynomial function

$=x^3+\frac{x^3+x-1}{x-1}\\$

$=x^3+x^2+\frac{x^2+x-1}{x-1}\\$

$=x^3+x^2+x+\frac{2x-1}{x-1}\\$

$=x^3+x^2+x+2+\frac{1}{x-1}$

Thus the required, divide is $=x^3+x^2+x+2+\frac{1}{x-1}$ .

Analyze the diagram below and complete the instructions that follow.<br><br> Find m

Stells [14]

Answer:

D. 70.53

Step-by-step explanation:

To solve this problem, one must use the right angle trigonometric rations. These ratios can be used to describe the ratio between the sides and an angle in a right triangle. Please note, each side is named relative to the angle that one is looking at, thus the same side can acquire different names based on the angle one uses to describe it. The trigonometric ratios are the following:

$sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}$

In this case, one is asked to find the measure of (<CBA), one is given the hypotenuse (the side opposite the right angle), and the side adjacent to this angle. Therefore, one should use the cosine (cos) function to find this angle.

$cos(\theta)=\frac{adjacent}{hypotenuse}$
