Answer

P = 147 million

Step by step explanation

P = Po r^t -------------(1)

Po initial population, r = rate, t = number of years

Here P = 139, Po = 134, t = 10.

Now plug in these values into the formula and find the rate r.

139 = 134r^10

r^10 = 139/134

r = (139/134)^1/10

Now we got r, now plug in the equation (1)

Let's find the population in the year 2014, here t = 24

P = 134 (139/134)^(24/10)

P = 134(139/134)^(2.4)

P = 134*1.1

P = 147.4

P = 147 million

The country's population in 2014 is 147 million (estimation).

Thank you.

What is the value of f(g(-3)?
Natalija [7]

Answer:

f(x) + g(x) = (-2x + 8)+ 3x

f(x) + g(x) = -2x + 8 + 3x   Combine like terms.

f(x) + g(x) = x + 8        

f(x) + g(x) = (f+g)(x) = x + 8

(f + g)(-1) = -1 + 8

(f + g)(-1) = 7
