Can someone check my work, if it’s right? Any corrects made please comment below!

Eva8 [605]

$f(g(x))$ represents the amount of money Sonia earns by working for $x$ hours.

$g(x)$ tells us how many loaves Sonia can bake in $x$ hours. So, for example, if she works for 10 hours, she can bake $\sqrt{2\cdot10^3}\approx44$ loaves of bread.

$f(x)$ tells us how much money she earns for the number of loaves $x$ sold. So, for example, if Sonia bakes 10 loaves of bread, then she earns $9\cdot10^2+1=901$ (insert units of money).

The composite function $f(g(x))$ is really a function of time, not number of loaves. So if Sonia works for 10 hours, then she makes about 44 loaves of bread, and so would earn about $9\cdot44^2+1=17,425$ .

In 1987, the population of country a was estimated at 87 million people, with an annual growth rate of 2.7%. the 1987 population

Ivanshal [37]

The annual multiplier of the population is 1 +2.7% = 1.027. So, after x years, the population is multiplied by 1.027^x. You want to find the value of x that makes this multiplier be 2.
2 = 1.027^x
log(2) = x*log(1.027)

Then, at a growth rate of 2.7%, the doubling time of the population is
x = log(2)/log(1.027) ≈ 26.02 . . . . . . the number of years after 1987

The population of Country A is expected to be double its 1987 value in the year 2013.
