A radioactive isotope decays according to the formula A(t)=Aoe^kt, where t is time in years. The initial amount was 10g and 8g of the isotope remained after 5 years. a) Find the decay constant,...

Select "Growth" or "Decay" to classify each function. Function Growth Decay y=200(0.5)^2t y=1/2(2...

Measuring the amount of carbon-14 enables an archaeologist to determine the age of artifacts and fossils. In 1962, skeletal and fossil remains of a woman were found. The fossil was estimated to be...

I know for growth it is a steeply rising curve and feel like it would be the same for decay just opposite? So, is it still B. ? A. A falling curve that approaches, but never...

The amount y (in grams) of the radioactive isotope phosphorus-32 remaining after t days is y=a(0.5)t/14, where a is the initial amount (in grams). Round the answer to the nearest hundredth of...

Tc-99m is used to detect tumors in the body. The half life of Tc-99m is only 6 hours. Suppose an initial dosage of 20 mCi was administered. Find the rule.

This is talking about approximate doubling time and half-time decrease

If the half-life of sodium-24 is 3.1 hours, then the time it takes sodium-24 to decay from 148 grams to 5.2 grams is?

An endangered frog species has a population of 10 000. Biologist estimate that the stock is decreasing at 3% per year. At this rate, approximately how many years will it take before only 80% of the...

A study is done on the population of a certain fish species in a lake. Suppose that the population size P(t) after t years is given by the following exponential function. P(t)= 280(0.81)^t. What percent...
