Step-by-step explanation:

$\sin^2 (\frac{\pi}{4} - \alpha) = \frac{1}{2}(1 - \sin 2\alpha)$

Use the identity

$\sin^2 \theta = \dfrac{1 - \cos 2\theta}{2}$

on the left side.

$\dfrac{1 - \cos [2(\frac{\pi}{4} - \alpha)]}{2} = \frac{1}{2}(1 - \sin 2\alpha)$

$\dfrac{1 - \cos (\frac{\pi}{2} - 2\alpha)}{2} = \frac{1}{2}(1 - \sin 2\alpha)$

Now use the identity

$\sin \theta = \cos(\frac{\pi}{2} - \theta)$

on the left side.

$\dfrac{1 - \sin 2\alpha}{2} = \frac{1}{2}(1 - \sin 2\alpha)$

$\frac{1}{2}(1 - \sin 2\alpha) = \frac{1}{2}(1 - \sin 2\alpha)$

Answer:

We can use excel regression data analysis tool to find the equation of the regression line that best fits the data.

The excel output is attached here.

Therefore, the equation of the linear regression is:

$\hat{y}=21.9028+1.5736x$

Where:

21.9028 is the intercept and 1.5736 is the slope.

If f(x)= 3x^2 + 3x^1/2 +3x what is the value of f(-9)

Dahasolnce [82]

Answer:

216 + 9i

Step-by-step explanation:

Given: f(x) = 3x² + 3 $x^{1/2}$ + 3x

When x = -9, f(x) equals to;

3(-9)² + 3(-9 $)^{1/2}$ + 3(-9)

243 + 3(3i) - 27

243 + 9i - 27

216 + 9i

lilavasa [31]

Answer:

Votes did Bill Clinton get in Texas in 1992 = 2317815

Step-by-step explanation:

Total votes received by Bill Clinton in 1996 = 2,495,683

Given that this was 177,868 more votes than he had received in 1992.

So the vote received in 1992 by Bill Clinton in 1992 is = ( Total votes received by Bill Clinton in 1996 ) - ( 177,868 )

⇒The vote received in 1992 by Bill Clinton in 1992 is = 2,495,683 - 177,868

⇒The vote received in 1992 by Bill Clinton in 1992 is = 2317815

Therefore votes did Bill Clinton get in Texas in 1992 = 2317815
