What is the simplified form of the expression square root of -64
we have
![\sqrt[]{-64}](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B-64%7D)
Remember that
64=2^6
and
i^2=-1
substitute
![\sqrt[]{-64}=\sqrt[]{(-1)(2^6)}=\sqrt[]{i^2\cdot2^6}=2^3i=8i](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B-64%7D%3D%5Csqrt%5B%5D%7B%28-1%29%282%5E6%29%7D%3D%5Csqrt%5B%5D%7Bi%5E2%5Ccdot2%5E6%7D%3D2%5E3i%3D8i)
<h2>option B</h2>
Answer:
B) 135 degrees
A) 83 degrees
Step-by-step explanation:
Each interior angle of a regular octagon is 135 degrees large.
In question two, <1 is an inscribed angle. A circle has 360 degrees, so the intercepted arc of <1 is 166, so m<1=83.

Answer:
y=17
Step-by-step explanation:
We move all terms to the left:
23-(y+40.)=0
We add all the numbers together, and all the variables
-(y+40)+23=0
We get rid of parentheses
-y-40+23=0
We add all the numbers together, and all the variables
-1y-17=0
We move all terms containing y to the left, all other terms to the right
-y=17
y=17/-1
y=-17
Answer:
The answer is B.
5/6 approximately 0.83 = 83%
71%
0.6 = 60%
56%
Hope this helps! Have a good night!
