In more conventional notation, ...
b(x) = -15x² +450x +325 . . . . 0 ≤ x ≤ 24
For 1990, x = 1990 - 1983 = 7
b(7) = -15·7² +450·7 +325 = 2740
The value of the card in 1990 was 2740.

Answer:
[rad] 2.41
Step-by-step explanation:
Since it gave you the point and the angle to find, you simply just have to solve for the inverse of cot. Remember cot is the opposite of tan, so cot is cos/sin. In that case, we plug into the calc (in radians):
cot^-1(-√5/2)
And we should get 2.41 as our answer!
