c.

Answer to Problem 15PS
Explanation of Solution
Given information:
The table shows the colonial population estimates of the American colonies.
Calculation:
Use the graphing utility to plot the data and the models from parts
d.
Identify the model, better fit for the data.
d.

Answer to Problem 15PS
Exponential model is well fitted for the data.
Explanation of Solution
Given information:
The table shows the colonial population estimates of the American colonies.
Predict the population of the United States in
Calculation:
From the graph we can say that exponential model is well fitted for the data, we can use this model to predict population of the United States in
Hence, exponential model is well fitted for the data.

- A 20 foot ladder rests on level ground; its head (top) is against a vertical wall. The bottom of the ladder begins by being 12 feet from the wall but begins moving away at the rate of 0.1 feet per second. At what rate is the top of the ladder slipping down the wall? You may use a calculator.arrow_forwardExplain the focus and reasons for establishment of 12.4.1(root test) and 12.4.2(ratio test)arrow_forwarduse Integration by Parts to derive 12.6.1arrow_forward
