MARK BRAINLIEST. Project: Explain the mathematics of roller coaster construction.
Imagine you are a roller coaster designer, and are asked to mathematically represent the curve of the first
drop of a new ride.
By looking at some of your favorite coasters, you determine that the optimal slope for the ascent, when
the car is being pulled up the slope by a chain, is 0.7. The slope of the first drop that will be the most
thrilling (without being dangerous) is -1.5.

answer: 15

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
