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.

It costs $520 to planf 4 acres of corn .how much would it cost to plant 0.6 acre of corn
Firlakuza [10]
To find an equivalent, divide 4 acres by .6 acres= 6.666...  then divide the cost of 4 acres ($520 by 6.666....= $78)  So it would cost 78 dollars to plant .6 acres of corn.

Find two consecutive integers such that the sum of the greatest integer and twice the lesser integer is 40.​
ziro4ka [17]

Answer:

13 and 14.

Step-by-step explanation:

So we have two consecutive integers.

Let's call the first integer a.

Since the integers are consecutive, the other integer must be (a+1) (one more than the last one).

We know that the sum of the greatest integer (or a+1) and twice the lesser integer (a) is 40. Therefore, we can write the following equation:

(a+1)+2(a)=40

The first term represents the greatest integer. The second term represents 2 times the lesser integer. And together, they equal 40.

Solve for a. Combine like terms:

a+1+2a=40\\3a+1=40

Subtract 1 from both sides. The 1s on the left cancel:

(3a+1)-1=(40)-1\\3a=39

Divide both sides by 3:

\frac{3a}{3}=\frac{39}{3}\\a=13

Therefore, a or the first integer is 13.

And the second integer is 14.

And we can check:

14+2(13)=14+26=40

Answer:

x^2-8x-9

x

2

−8x−9

Step-by-step explanation:

You have to factor the expression in order to get your answer

Do this by expanding out the expression: (x-10)(x-10)

Then factor by multiplying each of the components! Use the FOIL acronym to help you. FOIL stands for First, Outer, Inner, Last. Meaning multiply the first numbers of the expressions together, then the outers, then the inner two numbers, then the last two numbers of the expression.

Multiply x and x to get  , multiply x and -10 to get -10x, multiply -10 and x to get -10x, multiply -10 and -10 to get 100. Add them all together:  . Then combine like terms

<em>Explanation:
</em>Five ones, thirty-eight tens, twenty-seven hundreds, and five thousands equal to:

5 + 380 + 2700 + 5000

This is 8085 when added or eight thousand eighty-five in word form. This is also 8000 + 80 + 5 in expanded form.
