A new theme park is designing a rollercoaster. The height, $h$ (in meters), of the rollercoaster track above the ground is modelled by different functions along its path. For the first section of the ride, the height is modelled by a polynomial function. For the second section, the height is modelled by a trigonometric function. Finally, for the third section, the height is modelled by an exponential function.
b. The second section of the rollercoaster is modelled by the trigonometric function $h_2(x) = A\sin(B(x - C)) + D$, where \$100 < x \le 200$. The maximum height in this section is 35 meters and it occurs at $x = 130$. The minimum height is 19 meters and it occurs at $x = 180$. Find the values of $A$, $B$, $C$, and $D$.
