richard's annual take home pay is $34200. what is the maximum amount that he can spend per month paying off credit cards and loa
Umnica [9.8K]

Given is :

The annual income of Richard = $34200

Hence, his monthly income becomes = \frac{34200}{12} = $2850

So, the maximum amount that he can spend per month paying off credit cards and loans and not be in danger of credit overload can be a maximum of 20% of this income.

So, 20% of 2850 is = $570

Hence, approximately $570 can be spent a month.

As, the question has no options to choose from, but the question is complete in itself, so this is the best possible answer.

Find the Maclaurin series for f(x) using the definition of a Maclaurin series. [Assume that f has a power series expansion. Do n
Darina [25.2K]

Recall that for |<em>x</em>| < 1, we have

\displaystyle \frac1{1-x} = \sum_{n=0}^\infty x^n

Differentiating both sides gives

\displaystyle \frac1{(1-x)^2} = \sum_{n=0}^\infty nx^{n-1} = \sum_{n=0}^\infty (n+1)x^n

and multiplying both sides by 8 gives the series for <em>f(x)</em> :

f(x)=\displaystyle \frac8{(1-x)^2} = \boxed{8\sum_{n=0}^\infty (n+1)x^n}

and this converges over the same interval, |<em>x</em>| < 1, so that the radius of convergence is 1.
