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

Ivanshal [37]

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

$y = 24 * \frac{x}{10}$

Required

The interpretation of the question is to determine the value of y when x = 15

Substitute 15 for x in: $y = 24 * \frac{x}{10}$

$y = 24 * \frac{15}{10}$

$y = 24 * 1.5$

$y = 36$

The height is 36 meters
