1a) The domain is a set of all real numbers not equal to 5
1b) The domain is a set of all real numbers not equal to 4
<h3>What is the domain of the function?</h3>
Domain of a function is the set of all possible input values that make the function defined.
1a) We are given the function;
C(x) = -3²/(x - 5)
The domain will be a set of values that makes the denominator not equal to zero. Thus;
The domain is a set of all real numbers not equal to 5
1b) The function is; R(x) = 4x/(3x - 12)
The domain will be a set of values that makes the denominator not equal to zero. Thus;
The domain is a set of all real numbers not equal to 4
2a) Function is;
f(x) = (x + 8)/(2x - 1)
f(2) = (2 + 8)/(2(2) - 1)
f(2) = 10/3
f(0) = (0 + 8)/(2(0) - 1)
f(0) = -8
f(-1/2) = (-1/2 + 8)/(2(-1/2) - 1)
f(-1/2) = -15/4
2b) Function is;
r(t) = (t² + 8)/(t³ - 25t)
r(3) = (3² + 8)/(3³ - 25(3)) = -17/48
r(2) = (2² + 8)/(2³ - 25(2)) = -12/42 = -2/7
r(-1) = ((-1)² + 8)/((-1)³ - 25(-1)) = 9/24 = 3/8

The first thing you bought was a flight ticket, not shirt or shoes.
''I flew to Japan I bought shoes and I bought a shirt what did I buy first?'' passes for a simple mathematical puzzle and certainly requires the use a form of deductive reasoning and inference to be answered correctly.
<h2>Further Explanation</h2>
There are three things in the sentence that is worthy of note: Firstly, the buying of shoes, secondly, the purchase of shirt and thirdly, ''flew to Japan''.
A careful consideration must be based on what you bought that enabled you to get to the Japanese country. It is a known fact that if one must fly to another country, then a flight ticket must be purchased. To arrive at the correct answer, the only thing that enables you to get to the country to buy shoes and shirt was a flight ticket you got at the airport.
If the flight ticket was not purchased, even with your money with you, to buy the type of shoes and shirt you wanted to buy from Japan, you would not have been able to buy those items.
Therefore, if you flew to Japan to buy shoes and a shirt, you will have bought a ticket first.
KEYWORDS:
- japan
- shoes
- shirt
- flight ticket
- deductive reasoning
Step-by-step explanation:
1/5 is the rightt one
Solution :
Given :
Span of the roof = 48 feet
Length of the rafter = 30 feet (including the 4 feet overhung)
So, for the 30 feet long rafter, 26 feet will be rafter length from the high point of the roof to the edge of the roof and 4 feet will be the roof overhung.
Therefore, the horizontal span per rafter is
= 24 feet
a). So the rise of the roof is 
= 10 feet
b). Pinch of the roof is 
c). The percent of the roof used as overhung is
= 13.33 %
