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.

Find the ninth term of the sequence sqrt 5, sqrt 10, ^2sqrt 5
hjlf
The rule of geometric sequence is   ⇒⇒⇒ a * r^(n-1)
Where a is the first term and  r is the common ratio
for the given sequence  √5 , √10 , 2√5 , .......
a = √5
r = √10 / √5 = √2
The ninth term = √5 * (√2)^(9-1) = √5 * (√2)⁸ = 16 √5

the correct answer is the third option 16√5

suppose that a number written as a decimal has an infinite number of non- repeating digits after the decimal point. What is this
faltersainse [42]

Answer: Irrational number

If the decimal digits repeat forever, then the repeating decimal is considered rational.

For instance, 2/99 = 0.020202020202... where the "02" repeats forever

If we don't have such a pattern, then we cannot write the decimal as a fraction of two integers and the number is not rational. So it is irrational.
