If it is possible to label each element of an infinite set S with a finite string of keyboard characters, from a finite list cha
adelina 88 [10]

Answer:

D. We can label the rational numbers with strings from the set (1, 2, 3, 4, 5, 6, 7, 8, 9, / -) by writing down the string that represents that rational number in its simplest form. As the labels are unique, it follows that the set of rational numbers is countable.

Step-by-step explanation:

The label numbers are rational if they are integers. The whole number subset is rational which is written by the string. The sets of numbers are represented in its simplest forms. The rational numbers then forms numbers sets which are countable.

A local library claims it has 2.73x103 books. If there are 42 people in the building, how many books per capita are there?
Marizza181 [45]

Answer:

63 books per capita in the library

<em></em>

Step-by-step explanation:

Given

Books = 2.73 * 10^3

People = 43

Required

Determine the book per capita

To do this, we simply divide the number of books by number of person;

Average = \frac{Books}{People}

Average = \frac{2.73 * 10^3}{43}

Average = \frac{2.73 * 1000}{43}

Average = \frac{2730}{43}

Average = 63.488372093

Average = 63 (Approximated)

Hence;

<em>There are 63 books per capita in the library</em>

5( x-3 ) + 2x =41<br> What is x?
Valentin [98]

Answer:

8

Step-by-step explanation:

5 ( x - 3 ) + 2x = 41

5x - 15 + 2x = 41

5x + 2x - 15 = 41

7x - 15 = 41

7x = 41 + 15

7x = 56

x = 56 / 7

x = 8

HELP PLS I FORGOT LOL TYSM!
Valentin [98]

Answer:

A. The coefficients of the sum are whole numbers and the sum is a polynomial.

Step-by-step explanation:

The approach to demonstrate the closure property for the sum consists in defining what a polynomial is and demonstrate that the sum of two polynomials with integer coefficients is equal to a polynomial with integer coefficients. We proceed to show the proof below:

1) 5\cdot m -3, 2\cdot m + 4 Given

2) (5\cdot m -3)+(2\cdot m +4) Definition of addition

3) (5\cdot m +2\cdot m ) +[(-3)+4] Definition of substraction/Associative and Commutative properties

4) (5+2)\cdot m +1 Distributive property/Definition of substraction

5) 7\cdot m +1 Definition of addition/Result

Hence, the coefficients of the sum are whole numbers and the sum is a polynomial. The correct answer is A.
