√324 * √75 = √24300 = 90√3
so
90√3 / 9 = 10√3
answer is
D. last one 10√3 irrational
1. true
2. true
3. false
4. false
I think
Answer:
1) If it is spun 250 times, it will not land on W 207 times.
2) If it is spun 100 times, it will land on N 17 times (rounded up).
3) 1 out of 6
4) It has the same answer as 1) <em>(If it is spun 250 times, it will not land on W 207 times.)</em>
Remember that cos is just a translation of sin and vice versa.
So:
Sin(x) = Cos(90 - x)
Cos(x) = Sin(90 - x)
Therefore, to answer your question:
Cos(19) = Sin(90 - 19)
= Sin(71)
