Jim smith is a salesman who receives a 1,100 draw per week. He receives a 12% commission on all sales. Sales for Jim were 205,00
Sliva [168]
\bf {{ a}}\%\ of\ b \implies  \cfrac{{{ a}}}{100}\cdot b\implies {{ a}}\div 100\cdot b\\\\
-----------------------------\\\\
thus
\\\\
{{ 12}}\%\ of\ 205,000 \implies  \cfrac{{{12}}}{100}\cdot 205,000\implies {{ 12}}\div 100\cdot 205,000

Find the radius of convergence and the internval of convergence:
o-na [289]
You can use the root test here. The series will converge if

L=\displaystyle\lim_{n\to\infty}\sqrt[n]{\frac{(4-x)^n}{4^n+9^n}}

You have

L=\displaystyle\lim_{n\to\infty}\sqrt[n]{\frac{(4-x)^n}{4^n+9^n}}=|4-x|\lim_{n\to\infty}\frac1{\sqrt[n]{4^n+9^n}}

Notice that

\dfrac1{\sqrt[n]{4^n+9^n}}=\dfrac1{\sqrt[n]{9^n}\sqrt[n]{1+\left(\frac49\right)^n}}=\dfrac1{9\sqrt[n]{1+\left(\frac49\right)^n}}

so as n\to\infty, you have \left(\dfrac49\right)^n\to0, which means you end up with

L=\dfrac{|4x-1|}9

This is the interval of convergence. The radius of convergence can be determined by finding the half-length of the interval, or by solving the inequality in terms of |x-c| so that R is the ROC. You get

|4x-1|

Solve for x and y. Write any radical answers as "sqrt( )" or "squareroot( )".
LuckyWell [14K]

Answer:

x = 4 and y = 8

Step-by-step explanation:

This is a special right triangle with angle measures 90-60-30 degrees

The side lengths are like the following :

The side length that sees 90 degrees is represented with a

The side length that sees 60 degrees is represented with a\sqrt{3}

The side length that sees 30 degrees is represented with 2a

now, the angle measure that sees 60 degrees is given as 4\sqrt{3} so we understand that a is = 4 that's how we find the value of x and y
