Answer:

Correspondencia entre conjuntos:

a) Inyectiva: es cuando a cada imagen en el conjunto de llegada le corresponde un único origen, es decir, a distintos elementos del conjunto inicial, les corresponden distintos elementos del conjunto final.

b) Sobreyectiva: es si todos los elementos del conjunto final tienen al menos una correspondencia del conjunto inicial

c) Biyectiva: es cuando la correspondencia es inyectiva y sobre inyectiva a la vez

Correspondencia unívoca : es una correspondencia donde cada elemento del conjunto origen se corresponde con solo un elemento del conjunto de llegada.

Correspondencia biunívoca  es cuando a cada elemento del conjunto origen se corresponde con solo un elemento del conjunto llegada, y viceversa

Answer:

<2 = 129°

Step-by-step explanation:

if I || m then 5x+12 =m<2 and m<2 + 2x + 14 = 180°

2x + 14 + 5x + 12 = 7x + 26 =180°

7x = 154 ➡x = 21°

m <2 = 5×21 + 14

Solve |x| + 7 &lt; 4.
andrew11 [14]

Answer: Choice C (empty set)

The first thing to do is subtract 7 from both sides

|x| + 7 < 4

|x| + 7 - 7 < 4 - 7

|x| < -3

Recall that absolute value represents distance on a number line. Saying |x| is less than -3 means the distance is smaller than -3, which is impossible. Anything smaller than -3 is also negative. Distance can never be negative.

That leads us to the empty set as the solution. There are no values we can plug into any of the inequalities above, to have them lead to true statements.

Writing the special symbol \varnothing is one way to represent the empty set. Another way is to write curly braces only with nothing inside them like so: {  }, so its a set with nothing inside it more or less.

Given an int variable n that has been initialized to a positive value and, in addition, int variables k and total that have alre
azamat

Answer:

total = 0;

for (k = 0; k <= n; k++)

total += Math.pow(k,3);

Step-by-step explanation:

Here the variable total is declared and initialized with a value zero  

Then a for loop is defined with a counter k whose initial value is set to zero then a condition for the loop is that the counter k does not exceed n k<=n and then within the loop a statement which add the cube of the counter k to the variable total and still assigns it to the variable total is defined

  total += Math.pow(k,3);

What this program does is to obtain the sum of the cubes of k
