Review the graph. Which function represents the graph?

Answer: C

Step-by-step explanation:

Since y = 0 at x=3pi/2, we know that this is a cosine graph.

So to determine if its -cos or cosine, we can test the pt (0, 1).

Since cos(0)=1 whereas -cos(0)=-1, the answer is y=cos(x).

Margarita [4]

So for this, you'll be using the pythagorean theorem to solve for the height.

$9^2+b^2=16^2$

Solve the exponents to get $81+b^2=256$

Subtract 81 on each side to get $b^2=175$

Square root each side, and your answer should be $b= \sqrt{175}$ or 13.23 ft

Determine whether the sequence an=n312+n322++n3n2 converges or diverges. If it converges, find the limit.

strojnjashka [21]

Perhaps it suffices to say that

$\displaystyle\frac1{1^2}+\cdots+\frac1{n^2}=\sum_{k=1}^n\frac1{k^2}$

converges to $\frac{\pi^2}6$ as $n\to\infty$ , while $n^3\to\infty$ . Then

$\displaystyle\lim_{n\to\infty}a_n=\infty\cdot\frac{\pi^2}6=\infty$

so $a_n$ diverges.
