Calculate the compound interest.
butalik [34]
You use the first formula. You plug in the values to get A=400(1+(0.05/1))^6. You should get approximately $536.04. I used 0.05 because you need to change the percent to a decimal, and 1 for n because it is compounded annually, meaning once a year.

Question 3 of 13 Which represents the explicit formula for the arithmetic sequence a n = 15 + 5 ( n − 1 ) a n = 15 + 5 n - 1 in
tatyana61 [14]

Answer:

\textbf{Option C: \mathmode{\mathit{f(n) = 5n + 10}}}\\

Step-by-step explanation:

\textrm{There are two simple ways to solve the equation:}\\{\underline{\textbf{Method I:}}\hspace{3mm} \textup{\textrm{ Substitute \mathmode{n = 1} in the equation{\mathit{a} = 15 + 5(n - 1)}}}}\\\textup{\textrm{i.e., \mathrm{a = 15 + 5(0) = 15}}}\\\\

\textup{\textrm{In the options, again substitute \mathbf{n = 1}.}}\\\textup{\textrm{We can easily see that only Option \mathbf{C} satisfies the equation and renders 15. }}\\\textup{\textrm{Now for \textbf{\underline{Method II:}}\textup{\textrm{Simplify the given equation into \mathit{a = 15 + 5n - 5}}}}}\\\implies \textup{\textrm{a = 5n + 10}}\\
