Step-by-step explanation:
Answer:
28 billion dollars
Step-by-step explanation:
The total spent on research and development by the federal government in the United States during 2002–2012 can be approximated by
billion dollars (2 ≤ t ≤ 12), where t is the year since 2000.
If t=6, that is, In the year 2006,


=28 billion dollars (To the nearest billion dollars)
In 2006, the federal government of the United States spent approximately $28 billion on research and development.
Answer:


And replacing we got:

And for this case we can use the first point to find the intercept like this:

And solving we got:

And then the line equation would be given by:

Step-by-step explanation:
For this case we have the following two points given:

And for this case we want an equation for a line with the two points given by:

Wher m is the slope and b the y intercept. We can find the slope with this formula:

And replacing we got:

And for this case we can use the first point to find the intercept like this:

And solving we got:

And then the line equation would be given by:
