Answer:
p=ak^t
p1=491272*k^0
p2=782341*k^10
782341/491272 = k^10
k=1.047629
growth rate is 4.7629%
2012: predicted population is 491272*1.047629^12=858,642 people
1245863=491272*1.047629^t
1.047629^k=2.5363599
ln both sides is k ln 1.0476=ln 2.5363
t=20.000 years.
Rule of 72 would say 72/4.76 or 15.12 years for doubling
14.90 years
2017 predicted is 491272*1.0476^17 or 1083552, or more than actual, so the rate of growth is slowing down.
Total number of marbles = 17
3 are black.
Not black = 17 - 3 = 14.
Probability of not black = Number not black / Total
= 14 / 17
If you keep taking 2.5% of 80,000 it can give you 2,000 Have a happy day
Y is -2.08

Answer:
C = 11.18 D= 20
Step-by-step explanation:
Let's start with C
Square root both areas of the squares
Then use the Pythagoras Theorem: 
= C
Moving on to D
Square root both areas of the squares
29 is the hypotenuse, we are trying to find the other leg, so:
= D
