Increase from 491,675 in the year 2000 to 782,341 in 2010.
A. The solution for the exponential growth rate, B. Write the exponential growth function and C What should the population be in 2016.

A. 782341/491675 = 1.5911750648294096710225250419484, or a growth rate of 59% over 10 years. So:(1+k)^10 = 1.5911750648294096710225250419484ln (1+k)^10 = ln 1.591175064829409671022525041948410 ln(1+k) = ln 1.5911750648294096710225250419484ln(1+k) = ln 1.5911750648294096710225250419484/10 = 0.04644727777645335179835425806392e^0.04644727777645335179835425806392 = 1+kk = 1.0475428488243655419718940009655, or 4.75428488243655419718940009655% growth rate per year.

B. Population year t = 491675 x (1.0475)^(t-2000)

C. Population in 2016 = 491675 x (1.0475)^16 = 1033100.64 people

Solve for x. I need help with this problem. <br><br>​
Advocard [28]

Answer:

x = 9

Step-by-step explanation:

Rule: the two interior angles F and E when added, equal <FGH.

so

6x + 16 + 60 = 13x + 13  Combine the terms on the left.

6x + 76 = 13x + 13          Subtract 13 from both sides.

6x + 76-13 = 13x             Combine

6x + 63 = 13x                  Subtract 6x from both sides.

63 = 7x                            Divide by 7

63/7 = x

x = 9

I am struggling can I please have help?
tensa zangetsu [6.8K]

Each is a half of an apple, and there are 8 apples.

A factor is what you multiply.

So since there are 8 halves, you would do 8 x 1/2.

The answer to that equation is 4.

So that's how you get your answer, I hope this helps!
