Definition of eo-primes or relatively primes: Two numbers are said to be co-prime or relatively prime If their HCF IS 1 Hence to prove 847 and 2160 as co-prime numbers we will find their HCF and which should be 1

New steps to find HCF will be as under

2160 = 847 x 2+ 466
847 = 466 ×1 +381
466 = 381 x 1 + 85
381 =85 x 4+ 41
85 =41 x 2+3
41 =3 x 13+ 2
3 =2 x 1+1
2 =1 x 2+0

Therefore, the HCF=1 Hence, the numbers are co-primes (relatively prime).

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
