The polynomial x3 + 8 is equal to

Answers

Answer 1

Answer:

Answer:

$x^(3) +2^(3)=(x+2)(x^(2) -2x+2^(2) )$

Step-by-step explanation:

The general expansion of a polynomial of type $a^(3) +b^(3)$ is given as follows:

$a^(3) +b^(3) =(a+b)(a^(2) -ab+b^(2) )$

Given polynomial is $x^(3) +8$

This can be written as $x^(3) +2^(3)$ , which is of the form $a^(3) +b^(3)$ .

So we can use the general form to expand this polynomial where;

a→x

b→2

$x^(3) +2^(3)=(x+2)(x^(2) -x*2+2^(2) )$

$x^(3) +2^(3)=(x+2)(x^(2) -2x+2^(2) )$

Answer 2

Answer: The polynomial x3+8 is equal to (x+2)(x2-2x+4)

Hope this helps:)

The right answer for the question that is being asked and shown above is that: "C. TUVW was rotated 90° counterclockwise about the origin and then translated 4 units to the right." This is the sequence of transformations was performed on figure TUVW to produce figure TꞌꞌUꞌꞌVꞌꞌWꞌꞌ

A dollhouse has a bed with dimensions 1/12 the size of a queen-size bed. A queen-size bed has an area of 4,800 square inches, and a length of 80 inches. What are the side lengths of the dollhouse bed?

Answers

You could divide 4,800 by 80 to Find the answer. That will be 6 i think

Hi There! :P

Yeah the CORRECT answer would be 5 by 6.67 inches! :)

Make sure you get this right and I need proof

Answer:

-54

Step-by-step explanation:

100 square rooted is 10. 10*-6 is -60.

36 square rooted is 6.

-60+6=-54

After 1 year, a bank account contains $7,746.90. After 2 years, the same account contains $7,901.84. Assuming no deposits or withdrawals are made, which equation can be used to find y, the amount of money in the account after x years? (Round money values to the nearest penny.)

Answers

These are the choice given. I'll just substitute x with 1 and 2 to see if the amount corresponds to the given amount.
A.    y = 7591.96(1.02)x
y = 7,591.96(1.02)¹ = 7,743.80
  y = 7,591.96(1.02)² = 7,898.68

B.    y = 7591.96(0.02)x
y = 7,591.96(0.02)¹ = 151.84
y =7,591.96(0.02)² = 3.04

C.    y = 7595(1.02)x THIS IS THE CORRECT EQUATION.
y = 7,595(1.02)¹ = 7,746.90
y = 7,595(1.02)² = 7,901.84

D.    y = 7595(0.02)x

A used car salesman wants to be able to predict the resale value of a car based on the age of the car. What type of variable is the age of the car? * A. Categorical B. Quantitative (Discrete) C. Quantitative (Continuous) D. Cannot be determined without seeing the data.

Answers

Answer:

D. Cannot be determined without seeing the data.

Step-by-step explanation:

Option “D” is correct because age is a quantitative variable but if we look at the exact number or exact age of the car then the car’s age is quantitative discrete but if we look at the age of the car by going a number of years then it will be continuous. Therefore, without getting the exact information of the age of the car we cannot predict the type of variable. So the option “D” best fit for the answer.

Final answer:

The age of the car in a resale assessment is considered a Quantitative (Continuous) variable due to its numerical value and its ability to take any value within a given range, including fractions of a year.

Explanation:

The age of the car is a Quantitative (Continuous) variable. This is because age is a numerical value that can take any value within a given range, including fractions of a year. Continuous data can have an infinite number of values within a selected range, and age of a car could be represented in years, months, or even days if needed for precision sake in the case of used car sales, making it continuous.
