Una poblacion es atacada por una epidemia de gripe sea N(t)= numero de personas enfermas al tiempo t. En dias la epidemia inicio en N(0)= 50. Un matematico determina que la gripe se extiende a razón de f'(t)= 120t- 3t^2 personas por día. Determina
a) La función original que describe el comportamiento de la epidemia. (Aplica los mismos pasos explicados anteriormente.
b) ¿Cuántos enfermos habrán después de 15 días si no se controla la epidemia?
Answers
Answer:
Habrán 10175 enfermos a los 15 dias.
Step-by-step explanation:
La tasa de cambio de la población enferma por la epidemia de gripe es:
[tex]N'(t)=120t-3t^2[/tex]
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:
[tex]N(t)=\int N'(t)dt[/tex]
[tex]N(t)=\int (120t-3t^2)dt[/tex]
Integrando:
[tex]\displaystyle N(t)=120\frac{t^2}{2}-3\frac{t^3}{3}+C[/tex]
Simplificando:
[tex]\displaystyle N(t)=60t^2-t^3+C[/tex]
Para determinar el valor de C, usamos la condición inicial N(0)=50:
[tex]\displaystyle 50=60(0)^2-(0)^3+C[/tex]
Se tiene que C=50, y la función queda determinada como:
[tex]\displaystyle N(t)=60t^2-t^3+50[/tex]
b) El número de enfermos a los t=15 dias se determina substituyendo el valor en la función original:
[tex]\displaystyle N(15)=60(15)^2-(15)^3+50[/tex]
Calculando:
[tex]N(15)=13500-3375+50=10175[/tex]
Habrán 10175 enfermos a los 15 dias.

A balloon artist wants to make 6 different ut the kinds of balloon animals. She needs 4 balloons to make each animal. If the balloons come in packs of 8, how many packs will she need to buy? Part A Explain what you need to find first to solve the problem.
Answers
Answer:
She will need to buy 3 packs to make 6 different balloon animals.
Step-by-step explanation:
Given that the balloon artist wants to make 6 different animals, and each animal involves using 4 balloons, to make those 6 animals she must use 24 balloons, as the following calculation shows:
6 x 4 = 24
Now, since the balloons come in packs of 8 units, to make those 6 animals she must buy 3 packs of balloons, as this calculation also shows:
24 / 8 = 3.

The table below shows that the number of miles driven by Lily is directly proportional to the number of gallons she used. Gallons Used Miles Driven 37 754.8 47 958.8 50 1020 What is the constant of proportionality between the number of miles driven and the number of gallons used?
Answers
Answer:
20.4
Step-by-step explanation:
Constant of proportionality, k, is given as [tex] \frac{y}{x} [/tex].
Given that number of miles driven by Lily is directly proportional to the number of gallons she used, therefore the constant of proportionality between the number of miles driven and the number of gallons used can be determined by using any given pair from the table of values.
Using, (50, 1020),
constant of proportionality (k) = [tex] \frac{1020}{50} = 20.4 [/tex].
The constant of proportionality is 20.4 miles per gallon.
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
Let y represent the distance driven in miles for x galloons.
From the table, using the points (37, 754.8) and (50, 1020):
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-754.8=\frac{1020-754.8}{50-37}(x-37)\\\\y-754.8=20.4(x-37)\\\\y=20.4x[/tex]
Therefore the constant of proportionality is 20.4 miles per gallon.
