Arrange the steps in the correct order to solve: <br> sin 3pi/4 cos pi/12

Dmitry [639]

$\bf \textit{Product to Sum Identities}
\\\\
sin(\alpha)cos(\beta)=\cfrac{1}{2}[sin(\alpha+\beta)\quad +\quad sin(\alpha-\beta)]\\\\
-------------------------------\\\\
sin\left( \frac{3\pi }{4} \right)cos\left( \frac{\pi }{12} \right)\implies \cfrac{1}{2}\left[ sin\left( \frac{3\pi }{4}+\frac{\pi }{12} \right) ~~+~~sin\left( \frac{3\pi }{4}-\frac{\pi }{12} \right)\right]$

$\bf \cfrac{1}{2}\left[ sin\left( \frac{9\pi+\pi }{12} \right) ~~+~~sin\left( \frac{9\pi-\pi }{12} \right)\right]
\\\\\\
\cfrac{1}{2}\left[ sin\left( \frac{10\pi }{12} \right) ~~+~~sin\left( \frac{8\pi }{12} \right)\right]\implies 
\cfrac{1}{2}\left[ sin\left( \frac{5\pi }{6} \right) ~~+~~sin\left( \frac{2\pi }{3} \right)\right]
\\\\\\
\cfrac{1}{2}\left[\cfrac{1}{2}~~+~~\cfrac{\sqrt{3}}{2} \right]\implies \cfrac{1}{2}\left[ \cfrac{1+\sqrt{3}}{2} \right]\implies \cfrac{1+\sqrt{3}}{4}$

7. What is the solution to 9x = -63?<br> A. x=54<br> B. x= 7<br> C. x= -7<br> D. x = -54

Dmitry [639]

Given the equation 9x = -63, the numerical value of x is -7.

<h3>What is the solution to the given equation?</h3>

Given the equation in the question;

9x = -63

To determine the value of x, we divide both sides by the coefficient of x.

9x = -63

9x/9 = -63/9

x = -7

Given the equation 9x = -63, the numerical value of x is -7.
