Answer:
Since from the laws of exponents we have that x−n=1xn , it implies that we may write 18=8−1 . 18=123=2−3.
Step-by-step explanation:

Hope This Helps! :)
Supplementary means that the two angles, when put together, make a straight line (or 180 degree angle), so let's work this out.
A. The measure of angle 1 = the measure of angle 2: We know this is incorrect, just from looking at the picture, so let's cross that off.
B. The measure of angle 2 = the measure of angle 3: Angle 1 and angle 3 have the same measure, so since angle 2 isn't = to angle 1, angle 2 wouldn't be = to angle 3. Let's cross that off also.
C. Complementary means that the two angle put together make a 90 degree angle, but since angle three is already obtuse (more than 90 degrees), this answer is incorrect.
D. This answer is definitely correct! Angles 1 and 2 are supplementary, and angle 1 is equal to angle 3, therefore, angles two and 3 are also supplementary.
D. Is the correct answer!
Answer:
268 cm³
Step-by-step explanation:
Hey There!
So the first thing we want to do is find the formula for the volume of a sphere
π
so we just plug in 8 for r or radius
8²=64
Then we just round
Therefore the volume of the sphere is 268 cm³
