Población de alces. Se introducen cíen alces en una reserva zoológica, cada uno de un año de edad. El número N(t) de animales vi
frutty [35]

Answer:

El número de animales vivos después de 1, 5 y 10 años es 90, 60 y 35 respectivamente.

Step-by-step explanation:

Sabes que el número N(t) de animales vivos después de t años se predice mediante N(t) = 100*0.9^{t}

Para estimar el número de animales vivos después de, por ejemplo, 1 año debes simplemente reemplazar el tiempo t por el tiempo correspondiente, en este caso 1 año:

N(1) = 100*0.9^{1}

Resolviendo:

N(1) = 100*0.9^{1}= 100*0.9= 90

De manera similar, podes estimar el número de animales vivos después de 5 y 10 años. Esto es, reemplazas t por 5 años:

N(5) = 100*0.9^{5}= 100*0.59049= 59.049≅ 60

y t por 10 años:

N(10) = 100*0.9^{10}= 100*0.3487= 34.86 ≅ 35

<u><em>El número de animales vivos después de 1, 5 y 10 años es 90, 60 y 35 respectivamente.</em></u>
