An infinite strip with a symmetric pattern is called a frieze pattern.
There are only seven possible frieze pattern.
1. Translation symmetry only.
2. Glide reflection plus translation symmetry.
3. Reflection over a horizontal line plus translation.
4. Reflection over a vertical line plus translation.
5. Rotation (a half-turn about a point on the mid line of the strip) plus translation.
6. Reflection over a vertical line plus a reflection over a horizontal line plus translation.
7. Reflection over a vertical line plus glide reflection plus translation.
Answer:
Each friend gets 
of the popcorns.
Step-by-step explanation:
Nathalie's brother takes 1/5 of the popcorn for himself.
so there is ( 1 - 1/5)
= 4/5 of the popcorns left in the bowl
including Nathalie and her 3 friends, there are (3 + 1) = 4 persons.
So, each friend gets
=
of the popcorns
Step-by-step explanation:
Answer. Solenoid is the shape of a current-carrying conductor whose magnetic field pattern resembles that of a bar magnet. if it's incorrect sorry
Answer:
It would be C because it is dividing and he is using 1/4 each week out of the 3/5 he has.
F(x) = 3x² + 6x + 3 = 3(x² + 2x + 1) = 3(x + 1)² + 0
used: (a + b)² = a² + 2ab + b²
The vertex form: y = a(x - h)² + k
the coordinates of vertex: (h; k)
Therefore, your answer: (-1; 0).
