\begin{gathered} \theta=\frac{7\pi}{6} \\ 2\sin (\frac{7\pi}{6})=2(\frac{-1}{2})=-1 \\ 2\sin (\frac{7\pi}{6})=-1 \\  \\ \sin ^2(\frac{7\pi}{6})=(\frac{-1}{2})^2=\frac{1}{4} \\ \sin ^2(\frac{7\pi}{6})=\frac{1}{4} \\  \\ \sin (-\frac{7\pi}{6})=-\sin (\frac{7\pi}{6})=-(\frac{-1}{2})=\frac{1}{2} \\ \sin (-\frac{7\pi}{6})=\frac{1}{2} \end{gathered}

Whats the percent difference of 154 and 440
Semmy [17]
This would be a percent increase, so the formula would be:

New amount - Original amount / Original amount

Replace the numbers:

440 - 154 / 440

Simplify.

286 / 440

The chance would be 0.65, or 65%.

What is the number between 3400 and 4400
xxTIMURxx [149]
First find how many numbers are between the two by subtracting
4400 - 3400 = 1000
now to find half way between the two divide 1000 by 2 
1000/2 = 500
so the number between the two is 500 +3400 and 4400-500
which is 3900

Twice the sum of a number and 5 is equal to three times the difference of the number and 2
Alexxx [7]

Answer:16

Step-by-step explanation:

Let the number be X

Twice the sum of a number and 5

= 2X+5

Three times the difference of the number and 2

= 3(X - 2)

Since Twice the sum of X and 5 is equal to three times the difference of the X and 2, This means

2(X + 5 )= 3(X - 2)

2X +10 = 3X - 6

3X -2X = 10 + 6 = 16

X = 16

Check

2×(16+5) =3×(16-2)

2×21 = 3×14

42 = 42
