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:
760772
Step-by-step explanation:
Given that the population of city Z was 420,000 in the year 2000.
The population is projected to grow at a constant rate of 2 percent per year,
We have to find the closest to the projected population of city Z in the year 2030
Since growing at 2% per year treating 2000 as year 0 we can say
where t is the no of years lapsed after 2000.
So at the year 2030, t = 30
Population at th eyear 2030
= 
the projected population of city Z in the year 2030 is 760772
Answer:
Scale factor = ½
Step-by-step explanation:
The original image is the preimage = ∆ACB
The new image is the image = ∆DFE
The scale of factor of dilation = image/preimage = DF/AC
DF = 6 cm (given)
AC = 12 cm (given)
Plug in the values into the equation to find the scale factor of dilation:
Scale factor = 6/12
Scale factor = ½
