20 POINTS PLEAE HELP!!!!!!!!!!!!!!!
Alina [70]
His first payment is $100, thus a₁ = 100.

the next "term", month will be 1.1 times more than the one before, namely r = 1.1, the common ratio.

\bf \qquad \qquad \textit{sum of a finite geometric sequence}&#10;\\\\&#10;S_n=\sum\limits_{i=1}^{n}\ a_1\cdot r^{i-1}\implies S_n=a_1\left( \cfrac{1-r^n}{1-r} \right)\quad &#10;\begin{cases}&#10;n=n^{th}\ term\\&#10;a_1=\textit{first term's value}\\&#10;r=\textit{common ratio}\\&#10;----------\\&#10;a_1=100\\&#10;r=1.1\\&#10;n=20&#10;\end{cases}

\bf \sum\limits_{i=1}^{20}~100(1.1)^{i-1}\qquad \qquad\qquad  \qquad S_{20}=100\left( \cfrac{1-1.1^{20}}{1-1.1} \right)&#10;\\\\\\&#10;S_{20}=100\left( \cfrac{1-\stackrel{\approx}{6.727499949}}{-0.1} \right)\implies S_{20}\approx 100(57.27499949)&#10;\\\\\\&#10;S_{20}\approx 5727.4999493256

is the serie divergent or convergent?

well, to make it short, when the common ratio is 0 < | r | < 1, namely a fraction between 0 and 1, only then the serie is convergent, namely it reaches a fixed value, now in this case, 1.1 is a value larger than anything between 0 and 1, so no dice.

The variables x and y are inversely proportional, and y = 2 when x = 3. What is the value of y when x = 9?
Nina [5.8K]

Answer:

\huge \purple{ \boxed{ y =  \frac{2}{3} }}

Step-by-step explanation:

Since, the variables x and y are inversely proportional.

\therefore \: y  \:  \: \alpha \:  \:  \frac{1}{x}  \\  \implies \: y =  \frac{k}{x} \\ (k = constant)  \\  \implies \: xy = k ...(1)\\ plug \: y = 2, \:  \: x = 3   \: in  \: equation \: (1) \\ we \: find \\ 2 \times 3 = k \\ k = 6 \\ plug \:k = 6   \: in  \: equation \: (1)  \\ xy = 6 \\ (this \: is \: the \: equation \: of \: variation) \\ when \: x = 9 \:  \: y =?  \\  \\ 9y = 6 \\  y =  \frac{6}{9}  \\ \huge \red{ \boxed{ y =  \frac{2}{3} }}

Please help ! And explain if u can
irga5000 [103]

Answer:

Scalene Triangle

Step-by-step explanation:

If you mark the points on the graph, all three sides have different lengths and angles, therefor it is a scalene triangle.

It cannot be a right triangke bc there is no right angle, and no obtuse either so that crosses out obtuse as an option as well. In order to be an isoceles triangle it must have two sides of equal length, but it does not.
