Hi there.
The answer is g(1) = 3
Explanation:
Find the function that has x = 1 as a part of the domain. That is the second function that has x = 1 as a part of domain.
For the first function, the domain is lesser than or equal to -1, therefore, x = 1 isn't the part.
For the third function, the domain is greater than or equal to 2, meaning x = 1 isn't also the part of the domain as well. That leaves only the second function where -1 < x < 2 as x = 1 is the part.
Thus, our main function is —
Then evaluate the value of g(x), substitute x = 1 in the equation. However, the function doesn't have x-term.
Thus, answer the constant number.

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
