If sin^2(x) - 2sin(x) = 2, then sin(x) = _____.

alekssr [168]

Let z = sin(x).
.. z^2 -2z = 2
.. z^2 -2z +1 = 3
.. (z -1)² = 3
.. z -1 = ±√3
.. z = 1 -√3 . . . . . the positive solution is extraneous

sineoko [7]

Answer: a) 2092278989 b) 576, c) $\dfrac{576}{2092278989}$

Step-by-step explanation:

Since we have given that

Number of students = 16

Number of desks = 16

a) How many days must pass before the class must repeat a seating arrangement?

$16!=2092278989$

If the number of rows = 4

b) How many seating arrangements are there that put Larry, Moe, Curly, and Shemp in the front seats?

$4!\times 4!\\\\=24\times 24\\\\=576$

c) How many seating arrangements are there that put Larry, Moe, Curly, and Shemp in the front seats?

$\dfrac{576}{2092278989}$

Hence, a) 2092278989 b) 576, c) $\dfrac{576}{2092278989}$

Answer:

x = 16/3

Step-by-step explanation:

a) The rewritten equation is ...

$\dfrac{x-2}{x+8}=\dfrac{x-1}{x+12}$

b) The solution can be found as ...

$\dfrac{x-2}{x+8}-\dfrac{x-1}{x+12}=0\\\\(x-2)(x+12)-(x+8)(x-1)=0 \qquad\text{numerator of the difference}\\\\(x^2+10x-24)-(x^2+7x-8)=0\\\\3x-16=0\qquad\text{simplified}\\\\x=\dfrac{16}{3}\qquad\text{one solution}$

The solution set is {16/3}.

_____

The applicable rule of logarithms is ...

log(a) -log(b) = log(a/b)
