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>

the graph shows two functions, f(x) and g(x). if the functions are combined so that h(x) = f(x) - g(x), then the domain of the f
Sergio039 [100]

The domain of the function h(x) is x is greater than​ -1

<h3>How to determine the domain of the function h(x)?</h3>

The graphs of the functions are given as attachment

From the attachment, we have the following domains:

  • Domain of f(x): x > 2
  • Domain of g(x): x > -1

The equation of function h(x) is

h(x) = f(x) - g(x)

The domain of the function g(x) is greater than that of the function f(x)

This means that the function h(x) will assume that domain of the function g(x)

Hence, the domain of the function h(x) is x is greater than​ -1
