We turn -5,12 into polar coordinates. It's a Pythagorean Triple so
r = 13 Ф=arctan(-12/5) + 180° ( in the second quadrant )
so -5 = 13 cos Ф, 12 = 13 sin Ф
12 sin x - 5 cos x = 6.5
13 sinФ sin x + 13 cos Ф cos x = 6.5
13 cos(x - Ф) = 6.5
cos(x - Ф) = 1/2
cos(x - Ф) = cos 60°
x - Ф = ± 60° + 360° k integer k
x = Ф ± 60° + 360° k
x = 180° + arctan(-12/5) ± 60° + 360° k
That's the exact answer;
x ≈ 180° - 67.38° ± 60° + 360° k
x ≈ 122.62° ± 60° + 360° k
x ≈ { 62.62°, 182.62°} + 360° k, integer k
Answer:
The amount for early withdrawal is $204
Step-by-step explanation:
Annual interest rate = 5% = 0.05
Investment = $24,000
Annual interest rate * Investment = Annual interest
0.05 * $24,000 = $1,200
Penalty = Two months of interest
(months/months in a year) * Annual interest
(2/12) * $1,200 = 0,17
0,17 * $1,200 = $204,00
