G(x)=3x^2-2x+7/2x+5 <br> find g(-1)

KengaRu [80]

Answer:

g(- 1) = 4

Step-by-step explanation:

To evaluate g(- 1) substitute x = - 1 into g(x)

g(- 1) = $\frac{3(-1)^2-2(-1)+7}{2(-1)+5}$ = $\frac{3+2+7}{-2+5}$ = $\frac{12}{3}$ = 4

saw5 [17]

so, from 2006 to 2018 is 12 years then,

$\bf \qquad \textit{Amount for Exponential Decay} \\\\ A=P(1 - r)^t\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{initial amount}\dotfill &70000\\ r=rate\to 4\%\to \frac{4}{100}\dotfill &0.04\\ t=\textit{elapsed time}\dotfill &12\\ \end{cases} \\\\\\ A=70000(1-0.04)^{12}\implies A=70000(0.96)^{12} \\\\\\ A\approx 42889.68\implies A=\stackrel{rounded~up}{42890}$
