2. Margie Spencer wants to have $100,000 in her savings account in 20 years. If her account pays 6.6% annual

WITCHER [35]

$~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\dotfill & \$100000\\ P=\textit{original amount deposited}\\ r=rate\to 6.6\%\to \frac{6.6}{100}\dotfill &0.066\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{semiannually, thus two} \end{array}\dotfill &2\\ t=years\dotfill &20 \end{cases}$

$100000=P\left(1+\frac{0.066}{2}\right)^{2\cdot 20}\implies 100000=P(1.033)^{40} \\\\\\ \cfrac{100000}{1.033^{40}}=P\implies 27288.97\approx P$

In Exercise, find the derivative of the function.<br> y = e5x

mariarad [96]

Answer: The derivative of the function $y=e^{5x}$ is $5e^{5x}$ .

Step-by-step explanation:

We know that the derivative of $e^{ax}$ with respect to x is given by :

$\dfrac{d}{dx}(e^{ax})= a e^{x}$ (1)

The given function is $y=e^{5x}$

Differential both sides with respect to x , we get

$\dfrac{dy}{dx}=\dfrac{d}{dx}(e^{5x})$

$\Rightarrow\ \dfrac{dy}{dx}=5e^{5x}$ ( Using (1))

Therefore , the derivative of the function $y=e^{5x}$ is $5e^{5x}$ .
