Find the conjugate of the complex number 8+12i<br> 1) 96<br> 2) 8-12i<br> 3) -96i<br> 4) 20

timama [110]

Option 2 8-12i is correct.

Step-by-step explanation:

The conjugate of the complex number is obtained by changing the sign of the imaginary part.

In complex number 8+12i

8 is the real part and 12i is the imaginary part

The conjugate of 8+12i is 8-12i

So, Option 2 8-12i is correct.

#20 is this the correct answer bc I'm not sure what it means when it says "what are the areas of the two sectors" does that mean

Lelechka [254]

$\bf \textit{area of a sector of a circle}\\\\
A=\cfrac{\theta\pi r^2}{360}\qquad 
\begin{cases}
r=4\\
\theta=112
\end{cases}\implies A=\cfrac{112\cdot 16\cdot \pi }{360}\implies \boxed{A=\cfrac{224}{45}\pi}
\\\\\\
A\approx 15.64\\\\
-----------------------------\\\\
\textit{area of a circle is }\pi r^2\textit{ so the other side will be}
\\\\\\
\pi r^2-\cfrac{224\pi }{45}\implies 16\pi -\cfrac{224\pi }{45}\implies \boxed{\cfrac{496\pi }{45}}\implies A\approx 34.68$
