D= domain = farthest left and right
Domain = (3, infinite)
R = range = bottom to top
Range = (2,2)
Answer:
but many of them comes here to do time pass
Rotational symmetry is when an object looks the same when rotated around its center by an angle not equal to 0° (0) or any multiple of 360° (2π).
Based on the way these stations are connected, we can infer that there are <u>56 tubes. </u>
<h3>Number of tubes in Spaceland </h3>
Each pair of stations have 2 tubes. This means that every station is connected to each of the others.
We can therefore infer that each station has 7 tubes to the other stations.
The total number of tubes would therefore be:
= Number of stations x Number of tubes per station
= 8 x 7
= 56 tubes
In conclusion, there are 56 tubes.
