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

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

During a race, Bernie ran 9 meters every 4 seconds, while Wendel ran 2 meters every second and got a 9-meter head start. If the

Vsevolod [243]

No, because Bernie had to run 9 meters 7.77777778 time (70/9) and each of those 9-meter sections took 4 seconds, so her time was 31.1111111 (7.77777778*4). While Wendel had to run 61 meters 70-his headstart (9 meters) (70-9). So he only had to run 30.5 blocks of 2 meters (61/2). And since they're only 1 second long, it's 30.5*1=30.5. The answer then is NO because (Bernie) 31.1111111 seconds > 30.5 seconds (Wendel).

4.2 Write 1764 as a product of prime factors show your steps

Deffense [45]

Step-by-step explanation

first you have 1764 so you need to reduce it so you can keep on going through the line so I divided 1764 by 2 and I got 882. 2 is a prime number so I don't have to worry about it anymore. now I reduce 882 and get 2 and 441. 2 is prime so we don't need to worry about it anymore. now since we can't divide 441 by 2 we will use the next number 3. 441 divided by 3 is 147. 3 is prime so we don't need to worry about it anymore. 147 can't be divided by 2 so we will try 3 again and that works so 147 divided by 3 is 49. 3 is prime so we don't have to worry about it anymore. now we have 49 and 49 is a normal multiplication fact so we know that 49 divided by 7 is 7. and seven is prime so now you have have all the prime factors of 1764
