Complete Question:
The profile of a dam is modeled by the equation y = 24 (StartFraction x Over 10 EndFraction) squared, where x represents horizontal distance and y represents height, both in meters.
Point Z is at a horizontal distance of 15 meters from the left-most point of the dam. What is the height of the dam at point Z?
Answer:
The height is 36 meters
Step-by-step explanation:
Given

Required
The interpretation of the question is to determine the value of y when x = 15
Substitute 15 for x in: 



<em>The height is 36 meters</em>
Answer:
Check the distance between the lines at several places with a compass to ensure they are equidistant.
Step-by-step explanation:
The distance between the parallel lines is always constant and they never intersect with each other.
So, to verify if the lines constructed are parallel, we can check the following:
Check the distance between the lines at several places with a compass to ensure they are equidistant.
