PLEASE HELP ME 40 PTS!!!!!!
SSSSS [86.1K]

Answer:

The sequence converges to  infinity.

Step-by-step explanation:

a_n = \frac{n^3 - n}{n^2 + 5n}\\\\ \lim_{n \to \infty} a_n  =  \lim_{n \to \infty} \frac{n^3 - n}{n^2 + 5n}

                = \lim_{n \to \infty} \frac{n(n^2 - 1)}{n(n + 5)} \\\\= \lim_{n \to \infty} \frac{(n^2 - 1)}{(n + 5)}\\\\= \lim_{n \to \infty} \frac{n(n - \frac{1}{n})}{n(1 + \frac{5}{n})}\\\\= \lim_{n \to \infty} \frac{(n - \frac{1}{n})}{(1 + \frac{5}{n})}

denominator =  \lim_{n \to \infty}  1 + \frac{5}{n} = 1 +  \lim_{n \to \infty} \frac{5}{n} = 1+0 = 1

numerator =  \lim_{n \to \infty} n - \frac{1}{n} = \infty

Therefore,

             \lim_{n \to \infty} a_n  = \frac{ \infty}{1} = \infty

Akira is folding a piece of paper that is 0.2 millimeters thick in half. The thickness of the paper doubles with each fold. Let
Ostrovityanka [42]

Answer:

t(n)= 0.2 * 2ⁿ

Step-by-step explanation:

Thickness= 0.2 millimeters

paper = 1

n= number of folds

The exponential function will be given by

t(n)= 0.2 * 2ⁿ

so if there's a single fold

t(1)= 0.2 * 2¹

t(1)= 0.4 mm

Now for 2 folds the thickness will be

t(2) = 0.2 *2 ²

t(2)= 0.2 *4

t(2) = 0.8mm

The exponential that represents this scenario is

t(n)= 0.2 * 2ⁿ

And for 3 folds the thickness will be

t(3) = 0.2 *2 ³

t(3)= 0.2 *8

t(3) = 1.6 mm
