Answer:
The height of the roof in his house is 72.43 ft.
Step-by-step explanation:
The volume of square pyramid is :

B= area of the base.
h= the height.
Given that,
The roof is a square pyramid in shape. The volume of the roof is 18929.333 cubic feet.
The side length of the base of the roof is 28 feet.
Since the base of the roof is square in shape.
The area of the square is = side²
The area of the base is =(28×28) square feet
=784 square feet
Assume the height of the roof be h ft.
Then, the volume of the roof is = 
square feet.
According to the problem,


ft.
The height of the roof in his roof is 72.43 ft.
F(2)= -3(2)+9 = 3
f(0)= -3(0)+9 = 9
3f(2)-2f(0)
= 3(3)-2(9)
= -9
In the given table, we can calculate the sample space of the problem. The sample space includes all the categories of the people involved. The sample space is the total of the numbers given. This is equal to 300. The probability ofgetting someone who tests positive, given that he or she had the disease is 141/300 equal to 47 percent
The number of books that can be shelved is 45. So then we know that the amount that need to be shelved <em>can</em> be 45, if the bookshelf had 0 books on it. This means that it can have the equal part of the inequality sign.
However, the amount of book that need to be shelved cannot <em>exceed</em> 45, so b must be less than 45.
Therefore, the answer must be D) b ≤ 45.
ANSWER
(-∞,+∞)
EXPLANATION
The given polynomial function is:

The domain refers to all values of x that make the function defined.
Polynomial functions are defined for all real values of x
The domain is the set of all real numbers.
This is written in symbolic representation as
(-∞,+∞)
