A) En un videojuego el número de pruebas que hay que superar es el doble de las del nivel anterior, si en el nivel 1 hay dos pruebas, ¿Cuántas habrá en el nivel 5? ¿y en el 9? ES PARA MAÑANAAAAA

Answers

Answer:

En el nivel 5 habrá 32 pruebas mientras que en el nivel 9 habrá 512 pruebas.

Step-by-step explanation:

En un videojuego en el nivel 1 hay 2 pruebas.

El número de pruebas que hay que superar es el doble de las del nivel anterior. Entonces en el nivel 2 se deben superar 4 (2 pruebas del nivel 1*2, el doble) pruebas, mientras que en el nivel 3 hay que superar 8 pruebas (4 pruebas del nivel 2*2, el doble).

Una sucesión es una secuencia ordenada de números. Si observamos en este caso, la sucesión que se forma para calcular el número de pruebas es 2ⁿ, donde n es el número de nivel en el videojuego.

Entonces, por ejemplo, en:

el nivel 1: 2ⁿ= 2¹= 2 pruebasel nivel 2: 2ⁿ= 2²= 4 pruebasel nivel 3: 2ⁿ= 2³= 8 pruebas

Entonces, para calcular la cantidad de pruebas en el nivel 5 se realiza el cálculo:

2ⁿ= 2⁵= 32 pruebas

mientras que para calcular la cantidad de pruebas en el nivel 5 se realiza el cálculo:

2ⁿ= 2⁹= 512 pruebas

Entonces, en el nivel 5 habrá 32 pruebas mientras que en el nivel 9 habrá 512 pruebas.

Sabiendo como cambia el número de pruebas por nivel, veremos que en el nivel 5 hay 32 pruebas y en el nivel 9 hay 512 pruebas.

Sabemos que la cantidad de pruebas que hay que superar en cada nivel es el doble de las que hay en el nivel anterior.

Entonces, esto es una serie geometrica, que se puede escribir como:

[tex]A_n = A_1*2^{n - 1}[/tex]

Donde A₁ es la cantidad de pruebas en el primer nivel, que sabemos que son 2.

Entonces escribimos:

[tex]A_n = 2*2^{n-1} = 2^n[/tex]

En el nivel 5 tenemos n = 5, entonces la cantidad de pruebas que hay en e nivel 5 esta dado por:

[tex]A_5 = 2^5 = 32[/tex]

Es decir, hay 32 pruebas en el nivel 5.

Para el nivel 9 tenemos n = 9, entonces hay:

[tex]A_9 = 2^9 = 512[/tex]

Hay 512 pruebas en el nivel 9.

Shirts PLUS sells t-shirts for a base price of $8 per shirt plus a fixed fee of $23 shipping and handling for the whole order. Let x represent the number of shirts ordered and let y represent the total cost of the order.

y = 12x + 3

y = 8x + 23

Answers

Answer:

5 shirts

Step-by-step explanation:

4x=20

x=5 shirts

Answers

Answer:

D: 9.041 × 10^(10)

Step-by-step explanation:

The correct expression is;

(9.84 × 10^(10)) - (7.99 × 10^(9))

To subtract this, we need to ensure that both terms have the same powers.

Thus, (7.99 × 10^(9)) = (0.799 × 10^(10))

Lets now solve;

>> (9.84 × 10^(10)) - (0.799 × 10^(10))

Collecting like terms we have;

(9.84 - 0.799) × 10^(10)

>> 9.041 × 10^(10)

Answer:

A = 40

Step-by-step explanation:

A+B = 75

A+C = 61

Subtract

A+B = 75

-A-C = -61

----------------------

B-C = 14

B:C

5:3

for every 5B there are 3C

Replace B with 5/3 C
