Answer:
The professor wanted to order his class of 43 new handbooks. Each handbook was $7. What will be the total amount he will be spending on handbooks?
Answer:
-7/18
Step-by-step explanation:
cos(2x) = 1 - 2sin²x
cos(2x) = 1 - 2(5/6)²
= 1 - 2(25/36)
= 1 - 25/18
= -7/18
I'm not 100% sure but this is how i worked it out
1/3 x 114/1 = 38
114 - 38 = 76 hydrogen
Hope this helps
