Determine whether the following sequence is arithmetic, geometric, or neither.

Slav-nsk [51]

Answer:

Step-by-step explanation:

A geometric sequence has a common ratio r between consecutive terms

r = $\frac{a_{2} }{a_{1} }$ = $\frac{a_{3} }{a_{2} }$ = ...

$\frac{-14}{-7}$ = 2

$\frac{-28}{-14}$ = 2

$\frac{-56}{-28}$ = 2

There is a common ratio of 2 between consecutive terms.

Hence sequence is geometric → B

Can someone please help me figure out how to solve for x?

Anna007 [38]

Answer:

$x=30$

Step-by-step explanation:

Both triangles in this figure are similar. Therefore, we can set up the following proportion:

$\frac{21}{x}=\frac{14}{20}$ .

Cross-multiply to solve:

$14x=21\cdot 20,\\x=\frac{21\cdot20}{14},\\x=\fbox{$30$}$ .

Help please; I need the right answer

Ad libitum [116K]

Answer:

Step-by-step explanation:

$\cos x+\sqrt{2}=-\cos x \\ 2\cos x = -\sqrt 2 \\ \cos x = -\dfrac{\sqrt 2}{2}\\ \\ \Rightarrow x = \pm \arccos\Big(-\dfrac{\sqrt 2}{2}\Big)+2k\pi,\quad x\in \mathbb{Z}\\ \Rightarrow x =\pm\dfrac{3\pi}{4}+2k\pi\\ \\ \\k = -1 \Rightarrow x < 0\\\\ k=0 \Rightarrow x 2\pi$
