Arcsin x + arcsin 2x = π/3
arcsin 2x = π/3 - arcsin x
sin[arcsin 2x] = sin[π/3 - arcsin x] (remember the left side is like sin(a-b)
2x = sinπ/3 cos(arcsin x)-cosπ/3 sin(arc sinx)
2x = √3/2 . cos(arcsin x) - (1/2)x)
but cos(arcsin x) = √(1-x²)===>2x = √3/2 .√(1-x²) - (1/2)x)
Reduce to same denominator:
(4x) = √3 .√(1-x²) - (x)===>5x = √3 .√(1-x²)
Square both sides==> 25x²=3(1-x²)
28 x² = 3 & x² = 3/28 & x =√(3/28)
0.6 would be the same as $0.60 AKA 60 cents and 0.06 would be the same as 6 cents
The answer is going to be A.
Shadow 1 / Height 1 = Shadow 2 / Height 2
49 habitats are at the zoo because 245 divided by 5 is 49! (: (: (: hope I helped
It's D , the digit after the number ur rounding
