Help, i know the answer but i don’t know how to do the work

Diano4ka-milaya [45]

Answer:

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Simplifying each radical before combining them.

$\sqrt{45t}$

= $\sqrt{9(5t)}$

= $\sqrt{9}$ × $\sqrt{5t}$ = 3 $\sqrt{5t}$

-----------------------------------------------------------------------------

$\sqrt{125t}$

= $\sqrt{25(5t)}$

= $\sqrt{25}$ × $\sqrt{5t}$ = 5 $\sqrt{5t}$

---------------------------------------------------------------------------

Hence

2(3 $\sqrt{5t}$ ) - 3(5 $\sqrt{5t}$

= 6 $\sqrt{5t}$ - 15 $\sqrt{5t}$

= - 9 $\sqrt{5t}$ → C

P= $790, t= 3, r=4% compounded continuously : Find A

Savatey [412]

$\bf ~~~~~~ \textit{Continuously Compounding Interest Earned Amount}\\\\
A=Pe^{rt}\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to& \$790\\
r=rate\to 4\%\to \frac{4}{100}\to &0.04\\
t=years\to &3
\end{cases}
\\\\\\
A=790e^{0.04\cdot 3}\implies A=790e^{0.12}$
