Could someone please help mee<br> Step by step

Keith_Richards [23]

Let Q be the point (a, b). Since the midpoint of P (2, 3) and Q (a, b) is (4, 6), we have

(2 + a)/2 = 4

(3 + b)/2 = 6

Solve for a and b :

(2 + a)/2 = 4

2 + a = 8

a = 6

(3 + b)/2 = 6

3 + b = 12

b = 9

So the coordinates of Q are (6, 9).

If you earn $3500 per month and you expect your earnings to increase by 2.3% per year, how much do you think you will be making

Y_Kistochka [10]

$\bf \qquad \textit{Amount for Exponential Growth}\\\\
A=I(1 + r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\to &3500\\
r=rate\to 2.3\%\to \frac{2.3}{100}\to &0.023\\
t=\textit{elapsed time}\to &10\\
\end{cases}
\\\\\\
A=3500(1+0.023)^{10}$
