1) Plug the numbers into the equation for a simple interest rate. The equation is I = Prt, where P is the initial amount, r is the interest rate, and t is the time in years. 2) You have to turn the time into years, so put it over 12 (the months in a year) to turn it into a fraction for the unit of years, and plug in the equation to get I = 1200*0.81*(9/12). 3) Multiply this equation out to get 729.00, this is the answer. Answer: $729.00 interest. **TAKE THIS WITH A GRAIN OF SALT, you wrote the interest as dollars, but in this equation I assumed you meant to write it was a percent. If you did make a mistake and the 81 interest is a percent, then the math in this equation is correct. If it is an amount of money, then don’t copy it because it would be incorrect.
To simplify this:

You can factor the denominator and then cancel out some terms. But, this is not factorable. So, I think you are missing a term or you wrote this wrong.
Answer: m = 0
Step-by-step explanation: To find the slope of the line, we can use the graphing method. To do this, we start by plotting our two points.
Let's label (6, 1) as point A and (-6, 1) as point B.
Now, graph our line through the 2 points.
Now remember that the slope, or m, is equal to
the rise over run from point A to point B.
To get from point A to point B, we rise o units and run -12 units.
So our slope or rise / run is 0/-12 which simplifies to 0.
This should make sense because we have a horizontal or flat line and
remember that the slope of any horizontal or flat line is 0.

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.
