no because at the end it is 669 not 696 so it is not repeating decimal

Answer:

No, Marco is not correct. The number does not actually repeat because after each 9 there is an additional 6 before the next 9. The number is not a rational number.

(a) Starting with the geometric series [infinity] xn n = 0 , find the sum of the series [infinity] nxn − 1 n = 1 , |x| < 1.

Mila [183]

Let f(x) be the sum of the geometric series,

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

for |x| < 1. Then taking the derivative gives the desired sum,

$f'(x)=\displaystyle\boxed{\dfrac1{(1-x)^2}} = \sum_{n=0}^\infty nx^{n-1} = \sum_{n=1}^\infty nx^{n-1}$

Solve this equation. -4(p+2)+8=2(p-1)-7p+15

ratelena [41]

Hey there!

First we have to $distribute$ !

$-4 (p +2) = +8 = 2(p - 1) -7p + 15 \\ -4(p) + -4(2) + 8 = 2(p) +-2 + -7p + 15$

Now, we have to $combine$ our like terms

$-4p + (-8 + 8) = 2p + (-7p) + (-2) + 15 
$

Once we solve all the $like-terms$ we get

$-4p = 5p +13$

Now, we have to $add$ $5p$ to each of your sides

$-4p + 5p \\ = -5p + 13 + 5p$

Solve that part of the equation

$p= 13$

Good luck on your assignment and enjoy your assignment
