4 0

Answer:

See step by step.

Step-by-step explanation:

20 * 4 = 80

80 / 2 = 40

40 * 4 = 160

160 / 2 = 80

80 * 4 =320

if x is Nth number in the sequence:

if N is odd:

x = 20 * 4^{(N-1)/2} / 2^{(N-1)/2}

if N is even:

x = 20 * 4^{(N)/2} / 2^{(N)/2-1}

Una empresa elabora aceites de tres calidades distintas. Del primer aceite se elaboran 640 L, del segundo 800 L, y del tercero 4
Alecsey [184]

El mayor tamaño de los contenedores será de 160 litros.

Dado que una empresa elabora aceites de tres calidades distintas, y del primer aceite se elaboran 640 L, del segundo 800 L, y del tercero 480 L, si se quiere envasar el aceite en contenedores del mismo tamaño, sin mezclar los de distinto tipo, para determinar cuál será el mayor tamaño que puede tener el contenedor se debe realizar el siguiente cálculo, obteniendo el divisor mayor común de estos números:

  • Así, en tanto 480, 640 y 800 son divisibles por 80, resta determinar si también lo son por 160.
  • Entonces, dado que 480/160 es igual a 3, 640/160 es igual a 4 y 800/160 es igual a 5, el divisor mayor común de estos números es 160.
  • Por ende, el mayor tamaño de los contenedores será de 160 litros.

Bond [772]

Answer:

Mary's brother practiced 4 times as long.

Step-by-step explanation:

Mary practiced violin for 2 hours.

Her brother practiced trombone t times as long or 8 hours.

t times of 2 hours = 2t hours

But, 2t = 8

Divide both sides by 2.

t = 4

Hence, Mary's brother practiced 4 times as long as Mary.

SUPER URGENT: Complete the general form of the equation of a sinusoidal function having an amplitude of 6, a period of 2pi/3, an
mel-nik [20]

Answer:

y = 6·sin(3·(x - 1)) + c

Step-by-step explanation:

The general form of an equation for a sinusoidal function is presented ad follows;

y = a·sin(b·(x - h) + c

Where;

a = The amplitude of the equation

T = The period = 2·π/b

h = The phase shift

c = The vertical shift

From the question, we have;

a = 6,

2·π/3 = 2·π/b

∴ b = 3

h = 1

We get;

y = 6·sin(3·(x - 1)) + c.
