Determine whether the series is convergent or divergent by expressing sn as a telescoping sum (as in Example 8). [infinity] 6 n2

vekshin1

Answer:

Step-by-step explanation:

given

$\sum\limits^\infty_{n=3}\frac{6}{n^2-1}=\sum\limits^\infty_{n=3}\frac{6}{(n-1)(n+1)}\\\\=\sum\limits^\infty_{n=3}\frac{6}{2}(\frac{1}{n-1}-\frac{1}{n+1})\\\\=\frac{6}{2}\sum\limits^\infty_{n=3}(\frac{1}{n-1}-\frac{1}{n+1})\\\\=3[(\frac{1}{2}-\frac{1}{4})+(\frac{1}{3}-\frac{1}{5})+(\frac{1}{4}-\frac{1}{6})+(\frac{1}{5}-\frac{1}{7})+...]\\\\=3[\frac{1}{2}+\frac{1}{3}]=3[\frac{3+2}{6}]=3[\frac{5}{6}]\\\\=\frac{15}{6}=\frac{5}{3}$

Joe has 17 coins, nickels and dimes, that total up to $1.25. How many nickels does he have?

kifflom [539]

Answer:

9 nickels

Step-by-step explanation:

He has 17 coins.

$1.25 is 12 dimes and 1 nickel. But that is only 13 coins.

$1.25 can only be 17 coins if there were 9 nickels and 8 dimes.

Write the linear equation in slope intercept form 2x+By=16

allochka39001 [22]

Answer:

Part 1) $y=-\frac{2x}{B}x+\frac{16}{B}$

Part 2) $y=-\frac{1}{4}x+2$

Step-by-step explanation:

Part 1)

we know that

The equation of the line in slope intercept form is equal to

$y=mx+b$

we have

$2x+By=16$

Isolate the variable y

subtract 2x both sides

$By=-2x+16$

Divide by B both sides

$y=-\frac{2x}{B}x+\frac{16}{B}$

Part 2)

we know that

The equation of the line in slope intercept form is equal to

$y=mx+b$

we have

$2x+8y=16$

Isolate the variable y

subtract 2x both sides

$8y=-2x+16$

Divide by 8 both sides

$y=-\frac{2x}{8}x+\frac{16}{8}$

Simplify

$y=-\frac{1}{4}x+2$
