So if we think of a test tube, it looks sort of like a cylinder. This means that its cross-section would be a circle. To find out how many turns a piece of thread would make around the test tube, we need to find the circumference of the test tube, then divide the length of the string by the circumference.
Step 1) Find the circumference
C = pi x diameter
C = 3.14 x 3
C = 9.42
Step 2) Divide the length of the string by the circumference
90.42 / 9.42 = 9.5987
The string would make approximately 9.60 turns around the test tube.
Hope this helps!! :)
Answer:
1 is your answer
Step-by-step explanation:
Remember to follow PEMDAS.
First, plug in 12 for t
5 - (12/3)
Divide
5 - (4)
Simplify. Subtract
5 - 4 = 1

- Domain: <u>List of x-values that apply to the line.</u>
- Range: <u>List of y-values that apply to the line.</u>
- Function: <u>A relation that has every input (x) only have 1 output (y).</u>
- Interval Notation: <u>Lists the endpoint(s) of a line</u>, and whether it's a bracket or a parenthesis on the end determines whether the endpoint is included on the line. (e.g: [17,20). 17 is included in the line, 20 is not.)
Looking at the domain, the lines will continue to stretch infinitely. <u>Therefore, the domain is
</u>
Now looking at the range, the line stops at y = 1 and goes infinitely beyond it. <u>Therefore, the range is
</u>
Now lastly, to figure out if the relation is a function, conduct the vertical test. Since a definition of a function is that every input (x) has only 1 output (y), taking something vertical and sliding it across the graph should show only one point vertically. Since every x-value only has one y-value in this case, <u>this relation is a function.</u>
