Una poblacion es atacada por una epidemia de gripe sea N(t)= numero de personas enfermas al tiempo t. En dias la epidemia inicio
Lisa [10]

Answer:

<em>Habrán 10175 enfermos a los 15 dias.</em>

Step-by-step explanation:

La tasa de cambio de la población enferma por la epidemia de gripe es:

N'(t)=120t-3t^2

Donde t es el tiempo en dias, y se sabe que la epidemia inició en N(0)=50.

a)

Para encontrar la función original que describe el comportamiento de la epidemia, debemos integrar la función:

N(t)=\int N'(t)dt

N(t)=\int (120t-3t^2)dt

Integrando:

\displaystyle N(t)=120\frac{t^2}{2}-3\frac{t^3}{3}+C

Simplificando:

\displaystyle N(t)=60t^2-t^3+C

Para determinar el valor de C, usamos la condición inicial N(0)=50:

\displaystyle 50=60(0)^2-(0)^3+C

Se tiene que C=50, y la función queda determinada como:

\displaystyle N(t)=60t^2-t^3+50

b) El número de enfermos a los t=15 dias se determina substituyendo el valor en la función original:

\displaystyle N(15)=60(15)^2-(15)^3+50

Calculando:

N(15)=13500-3375+50=10175

Habrán 10175 enfermos a los 15 dias.
