Assuming that n 1 , rewrite the compound interest equation B t 900 1.185 t in the general form.

Rufina [12.5K]

$\bf \qquad \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\\
r=rate\to r\%\to \frac{r}{100}\\
n=
\begin{array}{llll}
\textit{times it compounds per year}
\end{array}\\
t=year
\end{cases}$

$\bf 1.185\implies 1+0.185\qquad\quad and\quad n=1
\\\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}\implies A=P\left(1+0.185\right)^{nt}\implies A=P\left(1+\frac{0.185}{1}\right)^{1\cdot t}$

so, the percentage of the rate is 0.185, what's that as a percentage? well, 0.185 * 100, 18.5%.

What is the y and x? <br> write an equation.

solong [7]

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~{{ 1993}} &,&{{ 14220}}~) 
% (c,d)
&&(~{{ 1997}} &,&{{ 9780}}~)
\end{array}
\\\\\\
% slope = m
slope \implies 
\cfrac{\stackrel{rise}{{{ y_2}}-{{ y_1}}}}{\stackrel{run}{{{ x_2}}-{{ x_1}}}}\implies \cfrac{9780-14220}{1997-1993}\implies \cfrac{-4440}{4}\implies -1110$

$\bf \stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-14220=-1110(x-1993)
\\\\\\
y-14220=-1110x+2212230\implies y=-1110x+2226450$

Answer:

The Code is F A M I L Y

the number left to the x gives you the slope, the plus or minus is where it intersects the y-axis (at x=0)
