Answer:
Step-by-step explanation:
The given equation is expressed as
y = 1/(x - 2)
We will assume values for x and determine the corresponding values for y. Therefore,
When x = 0, y = 1/(0 - 2) = - 1/2
When x = 1, y = 1/(1 - 2) = - 1
When x = 2, y = 1/(2 - 2) = 0
When x = 3, y = 1/(3 - 2) = 1
When x = 4, y = 1/(4 - 2) = 1/2
To plot the graph, we would choose a suitable scale for the x and y axis of the graph.
Let 2 cm represent 1 unit on the vertical axis.
Let 2 cm represent 0.5 unit on the x axis.
The graph is shown in the attached photo
The Height of the ceiling at the center is 57.6628 feet
In geometry, an ellipse is a two-dimensional shape, that is defined along its axes. An ellipse is formed when a cone is intersected by a plane at an angle with respect to its base.
It has two focal points. The sum of the two distances to the focal point, for all the points in curve, is always constant.
The General form of ellipse is
According to the question,
Length of whispering gallery is 130 feet
The foci are located 30feet from the center (0,0)
So, 2a = 130
=> a = 130/2
=> a = 65
and c = 30
As we know ,
=> c² = a² - b²
=> (30)² = (65)² - b²
=> 900 = 4225 - b²
=> b² = 4225 - 900
=> b² = 3325
=> b = 57.7 feet
Therefore , the height of the ceiling at the center is 57.6628 feet
