Construct a scatterplot and identify the mathematical model that best fits the data. Assume that the
model is to be used only for the scope of the given data and consider only linear, quadratic, logarithmic,
exponential, and power models. Use a calculator or computer to obtain the regression equation of the
model that best fits the data. You may need to fit several models and compare the values of R2.
A rock is dropped from a tall building and its distance (in feet) below the point of release is recorded as accurately
as possible at various times after the moment of release. The results are shown in the table. Find the regression
equation of the best model.

Browning labs is testing a new growth inhibitor for a certain type of bacteria. the bacteria naturally grows exponentially each hour at a rate of 6.2%. the researchers know that the inhibitor will make the growth rate of the bacteria less than or equal to its natural growth rate. the sample currently contains 100 bacteria.the container holding the sample can hold only 300 bacteria, after which the sample will no longer grow. however, the researchers are increasing the size of the container at a constant rate allowing the container to hold 100 more bacteria each hour. they would like to determine the possible number of bacteria in the container over time.create a system of inequalities to model the situation above, and use it to determine how many of the solutions are viable.
