Answer:
You can use combinations. I hope you've done combinations at your level.
Step-by-step explanation:
15C5 = 3003 ways
Proof:
SinA=k/g
cotA=k/j
secA=g/j
cosecB=g/k
tanB=l/k
cosB=k/g
Answer: x = 5/7
The numerator is the power, while the denominator is the index (thing next to radical).
The first set. It repeated 6 on the X value
The answer is 7.75. Since there can not be 7.75 days, you can round that to 8 and say that it's almost 8 days. Hope this helps!
