Answer:

All of them.

Step-by-step explanation:

For rational functions, the domain is all real numbers <em>except</em> for the zeros of the denominator.

Therefore, to find the x-values that are not in the domain, we need to solve for the zeros of the denominator. Therefore, set the denominator to zero:

x(x-1)(x^2-4)=0

Zero Product Property:

x\neq 0\text{ or }x-1\neq 0\text{ or }x^2-4\neq 0

Solve for the x in each of the three equations. The first one is already solved. Thus:

x-1\neq 0 \text{ or }x^2-4\neq 0\\x\neq 1\text{ or }x^2\neq 4\\x\neq 1 \text{ or }x\neq\pm 2

Thus, the values that <em>cannot</em> be in the domain of the rational function is:

x=-2,0,1,2

Click all the options.

Answer:

\Large \boxed{\mathrm{All \ options}}

Step-by-step explanation:

The domain of a function are all possible values for x.

To find the domain of a rational function, we set the denominator equal to 0, and solve for x. Those values of x are <em>not</em> included in the domain, since the denominator of 0 would make the rational function undefined.

x(x-1)(x^2-4)=0

Setting the factors equal to 0.

x=0 \\ \\ \\\\ x-1=0 \\ \\ x=1 \\ \\ \\ \\ x^2 -4=0 \\ \\ x^2 =4 \\ \\ x=\pm 2

The values of x that are <em>not</em> in the domain of the rational function are x=-2, x=1, x=2, and x=0.

Find the value of x. Round you answer to the nearest tenth.<br> 20<br> 18<br> X
Zielflug [23.3K]

Answer:

  21.9

Step-by-step explanation:

The altitude of an isosceles triangle bisects the base. So, x represents the hypotenuse of a right triangle with legs of 9 and 20. It can be found using the Pythagorean theorem:

  x^2 = 9^2 +20^2 = 81 +400

  x = √481 ≈ 21.932

The length x is about 21.9 units.

What is the right triangle definition of the sine function
navik [9.2K]
Answer: Choice B. Opposite/hypotenuse

The "opposite" refers to the leg that is furthest from the reference angle. The hypotenuse is always the longest side. The longest side is directly across from the 90 degree angle.
