A sample initially contains 200 grams of a certain radioactive isotope. After 5 hours, the amount has decayed to 177 grams. Let A(t) denote the amount (in grams) of the isotope after t hours. Assume that A ( t ) = C e ^(k t) for some constants C and k. How many hours before there is only 80 grams of the isotope?

A given bacteria culture initially contains 1500 bacteria and doubles every half hour. The number of bacteria p at a given time t (in minutes) is given by the formula p(t)=1500e^(kt) for some constant k. (You will need to find k to answer the following.) a) Find the size of the bacterial population after 110 minutes. b) Find the size of the bacterial population after 8 hours.​

A sample initially contains 200 grams of a certain radioactive isotope. After 5 hours, the amount has decayed to 177 grams. Let A(t) denote the amount (in grams) of the isotope after t hours. Assume that A ( t ) = C e ^(k t ) for some constants C and k. At what rate is the isotope decaying (in grams per hour) when t=6? Hint: use a derivative.

If a bacteria population starts with 125 bacteria and doubles in size every half hour, then the number of bacteria after t hours is n = f(t) = 125 · 4t. (a) Find the inverse of this function. t =  log4​(t125​)    Explain its meaning. a The inverse function gives the population after half an hour has passed. b The inverse function gives the population after 4 hours have passed.      c The inverse function gives the number of hours that have...
