Theme parks are big business. In the United States there are nearly 500 theme and amusement parks which generate over $10 billion a year in revenue. The theme park business is also growing in Europe and Asia. Rides are the main attraction at most parks, and at the center of this attention are the roller coasters. Engineers and designers compete to make them bigger and faster to increase park attendance. Roller coaster fans will wait in line for hours for a speedy, stomach-churning, head spinning 2-minute ride. What makes a roller coast fast

one set of data has more variation than the other. hope this !

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
