The spread of a virus can be modeled by exponential growth, but its growth is limited by the number of individuals that can be i
Nesterboy [21]

Answer:

  a) growth will reach a peak and begin declining after about 42.6 days. 5000 people will be infected at that point

  b) the infected an uninfected populations will be the same after about 42.6 days

Step-by-step explanation:

We have assumed you intend the function to match the form of a logistic function:

P(t)=\dfrac{Kpe^{rt}}{K+p(e^{rt}-1}

This function is symmetrical about its point of inflection, when half the population is infected. That is, up to that point, it is concave upward, increasing at an increasing rate. After that point, it is concave downward, decreasing at a decreasing rate.

a) The growth rate starts to decline at the point of inflection, when half the population is infected. That time is about 42.6 days after the start of the infection. 5000 people will be infected at that point

b) The infected and uninfected populations will be equal about 42.6 days after the start of the infection.

If f(x)= x2/x+3, find f(x+h)?
kompoz [17]

f(x+h) =  \frac{x^{2}+2xh+h^{2}  }{x+h+3}

Step-by-step explanation:

Given,

f(x) = \frac{x^{2} }{x+3}

To find the value of f(x+h) we need to replace x by x+h

Hence,

f(x+h) = \frac{(x+h)^{2} }{x+h+3}

= \frac{x^{2}+2xh+h^{2}  }{x+h+3}

[Here, we apply the formula of (a+b)^{2}= a^{2} +2ab+ b^{2}]
