Find the value of the cot 10° using your calculator.
Galina-37 [17]
The cotangent function can be obtained by taking the reciprocal of the tangent of the same angle. Using a calculator, taking the tangent of 10 degrees and taking the reciprocal of the answer would yield the correct one. With that, the correct answer would be D.) 5.671.

Which inequivalnet is equivalent to |x-4|&lt;9
nikklg [1K]

Answer:

something like this?

\left \{ {{x-4  

the top one is valid when x-4 >0

the bottom one is valid when x-4<0

Step-by-step explanation:

absolute value  |x-4|

means that in case x-4 is negative, we will use -(x-4)

if it's positive we use x-4

let's find the solution (where the original inequality is true)

negative case:

-(x-4)<9    -x+4 < 9  -x < 5  x>-5

positive case:

x-4 < 9   x < 13

to satisfy both conditions -5 < x < 13

How do you solve cos(pi/24) using Half-Angle formulas, and leaving in simplified form?
adoni [48]
\cos \frac{\theta}{2}=\sqrt{\frac{1+\cos \theta}{2}}&#10;\\&#10;\\ \cos{\frac{\pi}{24}}=\cos{\frac{\frac{\pi}{12}}{2}}=\sqrt{\frac{1+\cos \frac{\pi}{12}}{2}}= \sqrt{ \frac{1}{2}+ \frac{\cos \frac{\pi}{12}}{2}  } &#10;\\&#10;\\ \cos{\frac{\pi}{12}}=\cos{\frac{\frac{\pi}{6}}{2}}=\sqrt{\frac{1+\cos \frac{\pi}{6}}{2}}= \sqrt{ \frac{1}{2}+ \frac{ \frac{ \sqrt{3} }{2} }{2}  } =\sqrt{ \frac{2}{4}+  \frac{ \sqrt{3} }{4}   } = \sqrt{\frac{ 2+\sqrt{3} }{4} } = &#10;\\&#10;\\ =\frac{ \sqrt{2+\sqrt{3}} }{2} &#10;

\cos{\frac{\pi}{24}}= \sqrt{ \frac{1}{2}+ \frac{\cos \frac{\pi}{12}}{2}  } = \sqrt{ \frac{1}{2}+ \frac{\frac{ \sqrt{2+\sqrt{3}} }{2}}{2}  } = \sqrt{ \frac{2}{4}+ \frac{ \sqrt{2+\sqrt{3}} }{4}}  } =\sqrt{ \frac{ 2+\sqrt{2+\sqrt{3}} }{4}}  } &#10;\\&#10;\\\cos{\frac{\pi}{24}}=\frac{\sqrt{2+\sqrt{2+\sqrt{3}}}} {2}
