Answer:

3.6 feet

Explanation:

The height of the rollercoaster in feet throughout the underground section is modeled by the equation :

h(d) = 0.15d^2 - 1.5d ....(1)

We need to find the height of the rollercoaster 6 feet horizontally through the underground section.

Put d = 6 feet in equation (1) as follows :

$h(6) = 0.15(6)^2 - 1.5(6)\\\\h=-3.6\ \text{feet}$

or

h = 3.6 feet

So, the height of the rollercoaster 6 feet horizontal through the underground section is 3.6 feet.
