By using The half-angle formula
cos X/2 = ±√[(1 + cos X)/ 2]
But we have cos x=2/3
= ±√[(1 + 2/3)/ 2]
= ±√[(5/3 )/ 2]
= ±√[(5/5]
=±√1
Therefore answer is ±1
cos A/2 = ±√[(1 + cos A )/ 2]
It's 11040 plants because 92 percent of 12000 is 11040. (Idk if this is the best reasoning but :/)
The first box is 1
the second box is 50
the third box is 8
you’re welcome
Subtract 4 from both sides. You'll get 8x = 28. Solving for x, x = 28/8 = 7/2
This question have 2 different answer depending on what law he is stating in this problem
Solution 1
=> 204 / 32 = 6.38 times did 32 goes to 204.
Solution 2
=> 204 - 32 = 172
=> 172 / 32 = 5.38
=> 5.38 * 100% - 538%
