Answer:


9.543B

Step-by-step explanation: We have to find the world population in the year 2046, the formula for the population is as follows:


\begin{gathered} P(t)=\frac{11.8}{1+0.94e^{^((-0.030t))}}\Rightarrow(1) \\ 20\leq t\leq60 \end{gathered}

The year 2046 translates to:


t=2046-2000=46

Therefore the population would be:


\begin{gathered} \Rightarrow P(46)=(11.8)/(1+0.94e^((-0.030*46))^)\operatorname{\Rightarrow}(1) \\ \Rightarrow P(t)=(11.8)/(1+0.94e^(-1.38))=(11.8)/(1+(0.94)/(e^((1.38)))) \\ \Rightarrow P(46)=9.543 \end{gathered}

Therefore the population in 2046 would be as follows:


9.543B
