Question

A lab has been storing a radioactive substance fro a number of years. Here is a table showing the amount in grams over time.

years	1960	1970	1980	1990
Amount	500	300	180	108

a) Show that the data can be modeled by an exponential function.

b) Find the exponential function that models the amount of radioactive material by hand. You will need to choose your variables and identify what each represents.

c) If the trend persisted, when would you expect to have 20.52 grams left?

Use the table to answer the question. Hours Number of Bacteria 0 20 million 4 22 million 8 25 million 12 28 million 16 32 million 20 36 million 24 40 million 28 45 million The scatterplot of these data, when graphed, reveals what relationship between hours and the number of bacteria? Explain. The scatterplot reveals that hours and number of bacteria have a strong exponential relationship since the points closely follow an exponential curve. Since the number of bacteria increases as time increases, the relationship is negative. The scatterplot reveals that hours and number of bacteria have a strong exponential relationship since the points closely follow an exponential curve. Since the number of bacteria increases as time increases, the relationship is positive. The scatterplot reveals that hours and number of bacteria have a strong linear relationship since the points closely follow a line. Since the number of bacteria increases as time…
