Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Speed, Time, and Distance

Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 …

Profit and Loss

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experime…

Textbook Question

Chapter 4.2, Problem 9E

In the following exercises, find the exponential model as follows: If you do not have suitable technology, use the first and last data points to find a function. (See Examples 3 and 4.) If you have a graphing calculator or other suitable technology, use exponential regression to find a function. (See Example 4.)

Chinese Bank Assets The table shows the total assets (in trillion yuan) held in Chinese banks for the given years.

Year	2000	2005	2007	2009	2011	2013	2015
Assets	17	41	53	79	118	151	199

Find the exponential model for these data, where t = 0 corresponds to the year 2000.

Assume that the model remains accurate, and predict the total assets in 2018 and 2021.

Use a graphing calculator (or trial and error) to determine the first full year in which the total assets exceed 450 trillion yuan.
