What is the sum of this infinite geometric series?

barxatty [35]

$\qquad \qquad \textit{sum of an infinite geometric sequence} \\\\ \displaystyle S=\sum\limits_{i=0}^{\infty}\ a_1\cdot r^i\implies S=\cfrac{a_1}{1-r}\quad \begin{cases} a_1=\stackrel{\textit{first term}}{\frac{1}{8}}\\ r=\stackrel{\textit{common ratio}}{\frac{2}{3}}\\ \qquad -1 < r < 1 \end{cases}$

$\displaystyle\sum_{k=0}^{\infty} ~~ \underset{a_1}{\frac{1}{8}}\underset{r}{\left( \frac{2}{3} \right)}^k\implies S=\cfrac{ ~~ \frac{1}{8} ~~ }{1-\frac{2}{3}}\implies S=\cfrac{ ~~ \frac{1}{8} ~~ }{\frac{1}{3}}\implies S=\cfrac{3}{8}$

Write 4 (8m-7n) +6 (3n-4m) in standard form by expanding and collecting like terms.. show work

disa [49]

4(8m-7n) + 6(3n04m)

First, I will distribute the numbers outside of parentheses to the numbers inside of the parentheses:
(32m-28n) + (18n-24m)

Next, I will take out the parentheses:
32m-28n+18n-24m

After that, I will combine all of the numbers with the m variable:
32m-28n+18m-24m
32m+18m
50m

Lastly, I will combine all of the numbers with n as a variable, treating both like negative numbers because there is a subtraction sign before them.
50m-28n-24n
-28n-24n
-52n

This ends with this expression:
50m-52n

Let me know if you need any clarifications or anything :)

What is the distance between the points (4,3) and (1,-1) on the coordinate plane

Mariulka [41]

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We have the points (4, 3) and (1, -1). Substitute:

$d=\sqrt{(1-4)^2+(-1-3)^2}=\sqrt{(-3)^2+(-4)^2}=\sqrt{9+16}=\sqrt{25}=5$

<h3>Answer: The distance between the points (4, 3) and (1, -1) is equal 5 units.</h3>
