The total spent on research and development by the federal government in the United States during 2002–2012 can be approximated by S(t) = 3.1 ln t + 22 billion dollars (2 ≤ t ≤ 12), where t is the year since 2000.† What was the total spent in 2006 (t = 6)? (Round your answer to the nearest whole number.) $ billion

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

step-by-step explanation:

sry but any answer choices

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
