From 1960 to 2010, a certain money stock measure was growing at the rate of approximately 43e(1/2)x billion dollars per decade, where x is the number of decades since 1950. Find the total increase in the money stock measure from 1960 to 2010. (Round your answer to the nearest billion dollars.)

1222 billion dollars.

Step-by-step explanation:

To find the total increase from 1960 to 2010, we need to find the growth of each decade and sum them all:

In the period 1960-1970, we have x = 1, and the growth is:

In the period 1970-1980, we have x = 2, and the growth is:

The growth in the following 3 periods are:

So the total growth in the period 1960 - 2010 is:

Rounding to the nearest billion dollars, we have a total of 1222 billion dollars.

the answer to the question is a  

it has the same slope and the same y-intercept.
