Answer:
The function is:
y = 150*x
where y is the number of calories consumed, and x is the number of pieces of candy consumed.
Now, the domain of a function is the possible values of x that you can input in the function.
For this particular case you can have:
x = 0 (no pieces candy)
x = 1 (one piece of candy)
x = 2 (two pieces of candy)
Notice that x can be only whole numbers because, in principle, you can't eat a fraction of a piece of candy.
So we only use x = whole numbers.
Then the domain of the function is equal to all the natural numbers plus the zero, or:
D = {x ∈ N ∪ {0}}
"x belongs to the union between the set of the natural numbers and the zero"

Answer: d. s ≥ 23
Step-by-step explanation:
Let s be the side of the square.
We know that the perimeter of a square =4s
Let f(s)=4s
If the cardboard should have a perimeter equal to at least 92 inches, the inequality would look like
![4s\geq 92](https://tex.z-dn.net/?f=4s%5Cgeq%2092)
Divide both sides by 4, we get
![s\geq\frac{92}{4}\\\Rightarrow\ s\geq23](https://tex.z-dn.net/?f=s%5Cgeq%5Cfrac%7B92%7D%7B4%7D%5C%5C%5CRightarrow%5C%20s%5Cgeq23)
Thus, d. is the right answer. The reasonable domain of f(s) is ![s\geq23](https://tex.z-dn.net/?f=s%5Cgeq23)
Basically you are finding the volume of a rectangular prism of 3 by 2 meters cross section and 30 meters length. Volume = (3 m)(2 m)(30 m) = 180 cubic meters.
If 60% of the water has evaporated, 40% is left. Find 40% of 180 cubic meters to answer the 2nd part of this question.
So it's multiple choice?
whichever looks most like this is the answer:
30mn+6n-36m
