5/6 and 2/9......least common denominator is 18
so 5/6 = 15/18 and 2/9 = 4/18
1/12 and 3/8...least common denominator is 24
so 1/12 = 2/24 and 3/8 = 9/24
5/9 and 2/15...least common denominator is 45
so 5/9 = 24/45 and 2/15 = 6/45
Answer:
csc²(x)
Step-by-step explanation:
csc(x) = 1/sin(x)
sin²(x) + cos²(x) = 1
=> cos²(x) = 1 - sin²(x)
cos(2x) = cos²(x) - sin²(x) = (1 - sin²(x)) - sin²(x) =
= 1 - 2×sin²(x)
=> 2×sin²(x) = 1 - cos(2x)
sin²(x) = 1/2×(1-cos(2x))
=> 1 - cos(2x) = 2×(1/2×(1-cos(2x)) = 2×sin²(x)
=> 2 / (1-cos(2x)) = 2 / (2×sin²(x)) = 1/sin²(x) =
= 1/sin(x) × 1/sin(x) = csc(x)×csc(x) = csc²(x)

To add 11% to an amount means to multiply the amount by 1.11.
You can start with $115 and multiply it by 1.11 eleven times.
A quicker way is to find 1.11^11 and then multiply by $115.
$115 * 1.11^11 = $115 * = 3.151757 = $362.45
