Simplify. (-2)^-3 <br> ?????
Licemer1 [7]
Remember
(ab)^c=(a^c)(b^c) and
x^{-m}= \frac{1}{x^m}
so
(-2)^{-3}= \frac{1}{(-2)^3}= \frac{1}{(-1)^3(2)^3}=\frac{1}{(-1)(8)}=\frac{1}{-8}=\frac{-1}{8}

Does anyone know the answer?
grigory [225]

Answer:

12.7

Step-by-step explanation:

12.7  

Basically u are gonna wanna use pythagoras first

BC = √(12^2 - 6^2) = √(144 - 36) = √(108) = 10.39230485  

Also the Side Angle Side rule comes into play use the following

BC/sin(55) = CD/sin(90) <----- angle

BC/sin(55) = CD/sin(90) 

sin(90)BC/sin(55) = CD 

1*BC/sin(55) = CD 

BC/sin(55) = CD 

10.39230485/0.819152044 = CD 

12.68666167 = CD 

12.7 = CD
