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>

An element with mass 570 grams decays by 26.9% per minute. How much of the element is remaining after 14 minutes, to the nearest
Lina20 [59]

Answer:

element remained after 14 minutes = = 7.091 g =~ 10 g

Step-by-step explanation:

After every minute the amount remained will be

(100 - 26.9 ) % i.e. 73.1 %

which is 0.731 times as much as the amount was at the start.

if the number of minutes passed is represented by t the function f(t) represents the mass of element remaining our equation will be

f(t) = 570( 0.731) ^ t

t= 14 minutes

f(14) = 570 ( 0.731) ^ 14

      = 7.091 g =~ 10 g
