As baby boomers enter their golden years, the number of people afflicted with Alzheimer's disease is expected to rise dramatical

dybincka [34]

Answer:

Step-by-step explanation:

Given that the number of people with Alzheimer's disease in the United States age 65 years and over is projected to be

$N(t) = 0.00525t^2 +0.075t+4.7,(0 ≤ t ≤ 4)$

where N is in millions where year 2010 corresponds to t=0

For 2020, 10 years lapsed hence t= 1

a) $N(1) = 0.00525(1)^2 + 0.075(1) + 4.7\\=4.78025$

So 4.78025 million people

b) Growth = N(1)-n(0) =0.08025 million

c) N(4) = 5.084

Average rate of change = (5.084-4.7)/4 =0.096 million per decade
