Given that the number of people with Alzheimer's disease in the United States age 65 years and over is projected to be
where N is in millions where year 2010 corresponds to t=0
For 2020, 10 years lapsed hence t= 1
a) 
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

Answer:
Radius AC=12
Step-by-step explanation:
AB is a tangent to circle c so the tangent AB is perpendicular to the radius at A.
Then triangle ABC is right triangle at A.
So by Pythagoras theorem,
CB^2=AB^2 + AC^2
37^2= 35^2 + AC ^2
1369=1225 + AC^2
AC^2= 1369-1225= 144
AC=radical AC^2 =radical 144=12
Hope this helps...
