Step-by-step explanation:
a stable system of two phases one of which is dispersed in other form of particles
Answer:
We have sin² x + cos² x =1 for all real x.
Therefore, sin² x = 1 – cos² x = 1 – (8/17)² = 1 – 64/289 = 225/289 = (15/17)².
However, remember that if x² = a², then x can be +a or –a.
Therefore, sin x can be either –15/17 or +15/17.
Everyone but Anirban so far has forgotten the negative solution.
Step-by-step explanation:
Given that sinθ=817 and cosθ<0 , we have: cosθ=−√1−sin2θ. cosθ=−√1−(817)2. cosθ=−√1−64289.
Answer: x=8
for every 5 there is 2
so for x=8
there are four 5's in 20
I hope this is good enough:
-10 -9 -8 -6 -5 -4 -3 -2 -1 0 1 2 3 4
Go back -5 places and you will land on the answer of -8
Hope this helps! :)
Answer:
x + y=24
x=24-y = 3x+5y=100
3(24-y)+5y=100
72-3y+5y=100
72+2y=100
2y=28
y=14, since x=24-y
x=10
So there are 10 3-point questions and 14 5-point questions.
