No bc the width of the circular ring is only 12.67 inches
knowing circumference = pi * diameter, we can make the formula:
39.8 = (3.14)(diameter)
divide 39.8 by 3.15
diameter = 12.67 inches
12.67 inches is not greater than or equal to 18 inches
It would be 4 and 6 i solved it
Answer: y = 31 and x = 13
Step-by-step explanation: Look at the image from the top left to top right, then to bottom right to bottom left.
Answer:
a=-2
So yep. ;)
Step-by-step explanation:
Alright, so, (2,12), 2 is the x and 12 is the y.
Stick them into the equation: 
Then, solve:

a = -2
So yes, they're on the graph.
Hope this helped! :)
Answer: A <em>(first option)</em>: y-intercept = 9, zeros = {1, -1, 3, -3}
<u>Step-by-step explanation:</u>
The y-intercept is where the graph crosses the y-axis.
The zeros are the x-intercepts which is where the graph crosses the x-axis.
The graph touches the y-axis when y = 9
The graph touches the x-axis when x = -3, x = -1, x = 1, and x = 3
