Which statement describes the sequence defined by a Subscript n Baseline = StartFraction n cubed minus n Over n squared + 5 n En

Dominik [7]

Answer:

The answer is " The sequence converges to infinity. "

Step-by-step explanation:

Given:

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

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

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

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

Numerator $=\lim_{n\to \infty}n-\frac{1}{n}=\infty$

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

HELP NEEDED : Solve this using ELIMINATION: 8x + 8y = 240 4x + y = 54 Please!!!!

Licemer1 [7]

4x + y = 54

8x + 2y = 104

8x + 8y - (8x + 2y) = 240 - 104

6y = 136

y=22 2/3

4x+ 22 2/3 = 54

4x= 31 1/3

x= 7 5/6

if you take a look at the figure you see it consis of a rectangle with for cubs stcked up on one of the ends. This means the glue is in between the four cubs in the base and the stacked cubes. this means there are eight faces that have been attached since each cube is glued by one of their faces.
