If you're starting salary is 40,000 and you receive a 3% increase at the end of every year what is the total amount in dollars y

storchak [24]

$\bf \qquad \textit{Amount for Exponential Growth}\\\\
A=I(1 + r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\to &40000\\
r=rate\to 3\%\to \frac{3}{100}\to &0.03\\
t=\textit{elapsed time}\to &15\\
\end{cases}
\\\\\\
A=40000(1+0.03)^{16}\implies A=40000(1.03)^{16}$

What is the value of 5^3¡^9

OLEGan [10]

Answer:

$125i$

Step-by-step explanation:

We want to find

$5^3i^9$

This can be rewritten as;

$5^3i^8\times i$

$5^3(i^2)^4\times i$

Recall that; $i^2=-1$

$5^3(-1)^4\times i$

We evaluate now to obtain;

$125(1)\times i=125i$

How do I do multiplication?

levacccp [35]

<span>Multiply the number in the tens place of the bottom number by the number in hundreds place of the top number. Multiply 3 times 7 to equal 21. Add the 1 you carried to equal 22. You don't need to carry the 2 in 22, as there are no more numbers to multiply on this line, so you can just write it down next to the 6.</span>
