The rat population in a major metropolitan city is given by the formula n(t)=67e^0.035t where t is measured in years since 1994 and n(t)ismeasured in millions.

What was the rat population in 1994?   What is the rat population going to be in the year 2005?

A bacteria culture initially contains 2500 bacteria and doubles every half hour. The formula for the population is p(t)=2500e^(kt) for some constant k.

Find the size of the bacterial population after 100 minutes.    Find the size of the bacterial population after 4 hours.

Let f (x) = 7 - 1x + 14x^2 . Calculate the following values: f(a)= f(a+h)= Then simplify (f(a+h)-f(a))/h= for h does not equal 0

The answer for the last part should not have an h in the denominator after you have simplified.    So what is f(a)=   F(a+h)=   and f(a+h)-f(a)...
