ANSWER ALL PLEASE!
Applications of Exponential Equations Many real-life situations can be modeled by an exponential growth function of the form A(t) Ao ett constant that affects the rate of growth or decay, and t represents time. Using your knowledge of writing exponential equations that you did in the beginning of this chapter, what would A or an exponential decay function of the form A(t)-A ett where k represents the represent? 1. The amount of carbon-14 present in animal bones...

Question 4: Carbon dating (3 points) Archaeologists use the exponential, radioactive decay of carbon-14 to estimate the death dates of organic material. The stable form of carbon is carbon-12, and the radioactive isotope carbon-14 decays over time into nitrogen-14 and other particles. Carbon is naturally in all living organisms, and the carbon-14 that forms in the upper atmosphere enters into living things as long as they are taking in material (food, air, etc.) that contains carbon. We...

Radioactive decay occurs when a radioactive isotope ("parent" isotope) gradually transforms into a radiogenic isotope ("daughter" isotope) over time. This process is modeled by the following function: where r is the ratio of parent to daughter atoms, t is time and τΗ is called the halflife. The following table shows several parent-daughter pairs along with their half-lives. Daughter N14 Srs7 Ar4o Pb206 Pb207 Half-Life (years) 5730 48.8 x 109 1.3 x 109 4.6 x 109 0.7 x 10 arent Rbs7...
