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.

Answer:

<C=26

<B=48

<D=106

<F=42

Step-by-step explanation:

I labeled all the angles to help this make more sense :)

So first we find <C, which is supplementary to <E so just do 180-154=26

Next, we know that <F and <B are equal because they form corresponding angles.

Angles <C <D and <B form a triangle. The three angles of a triangle always equal 180. Now that we know angles <C and <B, we just do 180-26-48=106.

Lastly, to find angle A, we just take 180-106-48=42.

Hope this helps
