How many different passwords consisting of 3 different letters can be created using the letters A B C D E?

Mathematics
1 answer:
TiliK225 [7]3 years ago
6 0

Answer:

10 without repetitions, or 35 with repetitions

Step-by-step explanation:

Okay so basically if you allow repetitions, which would be repeating the same letter more than once, such as AAB, or BBD, or DDD, then there would be 35 total combinations. IF you do not allot repetitions and it has to be answers such as ABC, DEA, CAE, DCB, there would be only 10 possible passwords. Hope this helps. Brainiest is much appreciated

. En el triángulo ABC, la medida del ángulo exterior en el vértice B es el triple de la medida del ángulo C y la mediatriz de BC
Sliva [168]

Responder:

| AB | = 12m

Explicación paso a paso:

Verifique el diagrama en el archivo adjunto.

En el diagrama, se puede ver que el lado FC es igual al lado FB de acuerdo con el triángulo isósceles FBC.

Además, el lado FB es igual a AB ya que son paralelos entre sí.

De la declaración anterior, | FC | = | FB | y | FB | = | AB |

Esto significa | FC | = | FB | = | AB |

Por lo tanto desde | FC | = 12 m, | AB | = 12 m ya que ambos lados son iguales.

De ahí el lado | AB | se mide 12m

Please help me with this math question!
Alenkinab [10]
The bases are both 2, so we would subtract the exponents. This is because the rule is

(a^b)/(a^c) = a^(b-c)

In this case,
a = 2
b = 3/4
c = 1/2

So this means
b - c = (3/4) - (1/2) = (3/4) - (2/4) = 1/4

After subtracting the exponents, the final exponent is 1/4

So the expression simplifies to 2^(1/4) which is the same as \sqrt[4]{2} (fourth root of 2)

Kwans The Kenningy account balance was $20 his ending balance is zero dollars what integer represents the changing in his accoun
77julia77 [94]

The integer number that represents the changing in his account balance from beginning to end is of -20.

<h3>Which numbers belong to the set of integer numbers?</h3>

Non-decimal numbers, either positive or negative numbers, also zero, belong to the set, which can be represented by:

Z = {..., -3, -2, -1, 0, 1, 2, 3, ...}

A change can be represented by the <u>final value subtracted by the initial value</u>. For this problem, we have that:

  • The initial balance is of $20.
  • The final balance is of $0.

Hence the change in the balance is:

0 - 20 = -20.

And the integer is -20.
