I believe the answer is -21i
Answer:
sin∅= - √6/3
Step-by-step explanation:
Trigonometric function cos is even function which mean:
cos (-∅) = cos ∅
Trigonometric function sin is odd function which mean:
sin (-∅) = - sin∅ => sin∅ < 0
The basic trigonometric equation reads in this case with angle marked ∅:
sin²∅ + cos²∅ = 1 => sin²∅ = 1 - cos²∅ => sin²∅ = 1 - ( √3/3 )² =>
sin²∅ = 1 - (3/9) => sin²∅ = 1 - (1/3) = (3/3) - (1/3) = 2/3 => sin∅ = - √(2/3) =>
sin∅ = - √2/√3 => sin∅ = - √6/3

Answer:
$1904.76
Step-by-step explanation:
The interest formula is ...
I = Prt . . . . interest on principal P at rate r for t years
Solving for P, we find ...
P = I/(rt) = 200/(0.07·1.5) = 200/0.105 ≈ 1904.76
The principal amount was $1904.76.
