The number of shelves stephen can make is approximately 27
<h3><u>Solution:</u></h3>
Given that Stephen makes wooden shelves for his room
Stephen wants to make the shelves 3/4 foot long
He starts with a board that is 20 feet long
To find: number of shelves he can make
So the number of shelves stephen can make can make is found out by dividing 20 feet long board by 3/4 foot long


So the number of shelves stephen can make is approximately 27

Any polynomial function has the domain of all real numbers. So here we'll choose a polynomial function in order to illustrate this problem. So any polynomial of the form:

meets our requirements. Therefore, if we set:

Then, we'll have:
- A domain of all real numbers and the range all real numbers that are greater than or equal to zero.
This is shown graphically in the figure below.
2120/100=21.2
21.2x13=275.6
Therefore there are 275.6 acres remaining of pine trees.
Answer:
#2
Step-by-step explanation:
Step functions are functions (meaning that the x-values do not match with a y-value more than once) that increase or decrease at the same time. #1 is another type of piecewise function, while #3 is a choice to fool you.
