During a past epidemic, the number of infected people increased exponentially with time, or f (t) = ab^t , where f is the number of infected people at time t, in days. Suppose that at the onset of the epidemic (0 days) there are 30 people infected, and 6 days after the onset there are 300 people infected.
a) Specify the function f, that models this situation, by determining a and b.
b) Predict the number of people who will be infected at the end of 2 weeks using your answer to a.
c) According to this function, approximately when will the number of infected people reach 10,000? (Use logarithms to sove this part - a guess and check answer WILL NOT be accepted)
During a certain epidemic, the number of people that are infected at any time increases at rate proportional to the number of people that are infected at that time. 1,000 people are infected when the epidemic is first discovered,
The 1918 Influenza Epidemic was the worse one on record. People infected early in the epidemic had a mild flu, while those later infected had a much more severe form of the disease. What is the explanation for this observation and
An influenza epidemic has an infection rate modeled by I ' (t)=30 e0.04 t , where t is time measured in days since the start of the epidemic on January 14th , and I '(t) measures the infection rate in people per day. On January

I cannot understand how you worked out this problem Bob. Could you explain the steps you made? Algebra - bobpursley, Wednesday, April 27, 2011 at 10:36am if it is as I wrote it, then (45x/6t)11x= 45*11*x^2/6t = 15*11*x^2/2t=
If you treat the day of the month as a number (March 12th is the number 12, April 4th is the number 4), what is the average value of the numbers that represent the 6 Tuesdays that fall after September 12, 2011
