To find the value for a in this equation, we can follow the next steps:

$\frac{a}{5}-23=-25$

First, multiply all of the equation by 5:

$5\cdot(\frac{a}{5}-23=-25)\rightarrow\frac{5}{5}\cdot a-115=-125\rightarrow a-115=-125$

Finally, add 115 to both sides of the equation:

$a-115+115=-125+115\rightarrow a+0=-10\rightarrow a=-10$

Therefore, the value for a is a = -10.

Use the power series for 1 1−x to find a power series representation of f(x) = ln(1−x). What is the radius of convergence? (Note

Viktor [21]

a. Recall that

$\displaystyle\int\frac{\mathrm dx}{1-x}=-\ln|1-x|+C$

For $|x|$ , we have

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

By integrating both sides, we get

$\displaystyle-\ln(1-x)=C+\sum_{n=0}^\infty\frac{x^{n+1}}{n+1}$

If $x=0$ , then

$\displaystyle-\ln1=C+\sum_{n=0}^\infty\frac{0^{n+1}}{n+1}\implies 0=C+0\implies C=0$

so that

$\displaystyle\ln(1-x)=-\sum_{n=0}^\infty\frac{x^{n+1}}{n+1}$

We can shift the index to simplify the sum slightly.

$\displaystyle\ln(1-x)=-\sum_{n=1}^\infty\frac{x^n}n$

b. The power series for $x\ln(1-x)$ can be obtained simply by multiplying both sides of the series above by $x$ .

$\displaystyle x\ln(1-x)=-\sum_{n=1}^\infty\frac{x^{n+1}}n$

c. We have

$\ln2=-\dfrac\ln12=-\ln\left(1-\dfrac12\right)$

$\displaystyle\implies\ln2=\sum_{n=1}^\infty\frac1{n2^n}$

Looking at the bill in a restaurant Mr. Svoboda had a difficult time reading the price of the meal. But he could see that 5% tax

padilas [110]

Answer:

The tip would be worth $2.19

Step-by-step explanation:

x - is the full bill

1/20 x = $0.73

Solve for x:

Multiply both sides by 20.

<u>20</u>*(1/20 x) = <u>20</u>*(0.73)

x = 14.6

Now we just have to find 15% of x to find the tip.

3/20 (14.6) = 2.19

So, the tip would be worth $2.19
