El tamaño de cierto cultivo de bacterias se multiplica por 2 cada 30 minutos. Si suponemos que el cultivo tiene inicialmente 256
Oduvanchick [21]

Answer:

La población de bacterias después de tres horas es de 2^{14} bacterias.

Step-by-step explanation:

En este enunciado observamos un caso de progresión geométrica, en donde la población de bacterias se duplica cada treinta minutos, es decir:

\frac{p(n\cdot\Delta t)}{p(0)} = 2^{n} (1)

Donde:

\Delta t - Intervalo de tiempo requerido para el incremento geométrico de la población, en minutos.

n - Número de períodos para incremento geométrico, sin unidad.

Sabemos que la población inicial de bacterias es 256 y que 3 horas son 6 veces 30 minutos. Entonces, tenemos la siguiente razón:

\frac{p(6\cdot \Delta t)}{p(0)} = 2^{6} (2)

Si sabemos que p(0) = 256, entonces p(6\cdot \Delta t) es:

p(6\cdot \Delta t) = 2^{6}\cdot p(0)

p(6\cdot \Delta t) = 2^{6}\cdot (256)

p(6\cdot \Delta t) = 2^{6}\cdot 2^{8}

p(6\cdot \Delta t) = 2^{14}

La población de bacterias después de tres horas es de 2^{14} bacterias.

The equation y=12x describes the amount of money Louis earns, where x is the number of hours he works and y is the amount of mon
igor_vitrenko [27]

Answer:

So, Louis earns 12 dollars per hour.

To find the rate for Carl, we need to divide the money earned from the hours.

\frac{dollars}{hours} =\frac{45}{3}=15

Carl earns 15 dollars per hour.

(a) Carl earns 15 dollars per hour.

(b) Carl earns more than Louis, because 15 > 12.

You can sell 110 pet chias per week if they are marked at $1 each, but only 50 each week if they are marked at $2/chia. Your chi
sweet-ann [11.9K]
Demand:

price         quantity q(p)

p                     q

1                    110

2                     50

linear function:

q - 110        110 - 50
---------- =  --------------
  p - 1             1 - 2

 q - 110
----------- = - 60
  p - 1

q - 110 = - 60 (p - 1)

q - 110 = -60p + 60

q = - 60p + 170

Answer: demand equation: q(p) = 170 - 60p

Supply

price         quantity

p                   q

1                   50

2                  110

linear function

 q - 50       110 - 50   
--------- =  --------------
  p - 1        2 - 1

q - 50
-------- = 60
p - 1

q - 50 = 60 (p - 1)

q - 50 = 60p - 60

q = 60p - 60 + 50

q = - 10 + 60 p

Answer: supply q(p) = - 10 + 60p

Price at which there is neither a surplus nor a shortage => equilibrium price

=> demand = supply

=> 170 - 60p = -10 + 60p

=> 60p + 60p = 170 + 10

120p = 180

p = 180 / 120 = 1,50

Answer: at $ 1,50
