Answer:

Option 2

Step-by-step explanation:

Since theta is in the third quadrant, the sine of theta is negative.

By the Pythagorean identity,

$\sin \theta=-\frac{\sqrt{105}}{13}$

So, using the double angle formula for sine, we get that

$\sin 2\theta=\frac{16\sqrt{105}}{169}$

Answer:

Step-by-step explanation:

The square of the value in the empty space is the constant in the expanded expression. That is ...

[ ]² = 1

The value in the space is ...

[ ] = √1 = 1

The filled-in equation is ...

(3x -1)² = 9x² -6x +1

_____

The expansion of the square of a binomial is ...

(ax -b)² = a²x² -2abx +b²

Above, we used the constant term to find 'b', but we could also have used the linear term:

-6x = -2(3)bx . . . . . a=3 in this problem

1 = b . . . . . . . divide by -6x
