Answer:
7,2
Step-by-step explanation:
So the question if find y'' for 4y=cos2x
First, find y by dividing by 4. y = cos2x/4
Then, take the first derivative. y' = -sin2x/2
Then, take the second dervative. y'' = -cos2x
7/8 / 11/12. First get the reciprocal of 11/12 (which is 12/11). Then multiply by the reciprocal. 7/8 * 12/11 = 84/88
don't forget to simplify
21/22
Answer:
n=4p
Step-by-step explanation:
1. group like terms: -7p+5n+3n=25p
2. add similar elements, 5n +3n = 8n --> -7p+8n=25p
3. add 7p to both sides: -7p+8n+7p=25p+7p
4. simplify : 8n=32p
5. divide both sides by 8:
6. evaluate: n=4p
