Answer:

D. 16,384

Step-by-step explanation:

The given sequence (including "6") is neither arithmetic nor geometric. The 14th term cannot be predicted. (It can be anything you like.)

Based on the answer choices, we assume the intended sequence is the geometric sequence ...

2, 4, 8, 16, 32, ...

which has formula ...

an = 2^n

Then the 14th term is ...

a14 = 2^14 = 16,384

I don't want the answer, but I want to know how you got that answer.

Answer:

n = 5

Step-by-step explanation:

$4n+5n+15=5n+7n\\\\9n+15=12n\\\\9n+15-15=12n-15\\\\-3n=-15\\\\\frac{-3n=-15}{-3}\\\\ \boxed{n=5}$

Hope this helps.

Simplify the identity: tan cos/sin

xxMikexx [17]

I am going to simplify the top before simplifying the rest.

tan = sin/cos, so tan * cos simplifies down to sin in the numerator. which leaves sin/sin which equals 1.

to make a long story short the answer is 1

Answer:

D) x² -x - 10 =0

Step-by-step explanation:

Given that

$\frac{2}{3x-6} - \frac{1}{3x+6} = \frac{1}{3}$

L.C.M

$\frac{2(3x+6)-(3x-6)}{(3x+6)(3x-6)} = \frac{1}{3}$

$\frac{(6x+12-3x+6)}{(3x+6)(3x-6)} = \frac{1}{3}$

$\frac{(3x+18)}{((3x)^{2} )-(6)^{2} } = \frac{1}{3}$

⇒ $3(3x+18) = 9 x^{2} - 36$

⇒ 9 x + 54 = 9 x² - 36

⇒ 9 x² - 36 - 9x - 54 =0

⇒ 9 x² - 9x - 90 =0

⇒ 9(x² -x - 10 ) =0

⇒ x² -x - 10 =0
