Z has rotational symmetry.
Step-by-step explanation:
The letters H, I, O, S, X, and Z have rotational symmetry. Out of the letters you have:
Z is your answer.
He ran 8.6........ mikes per minute, I just divided 104÷12=8.66666666666666, but all if those sixes don't matter.
I hope this helps!
Divide 44 by the percentage:
44 / 0.55 = 80
44 is 55% of 80
Answer:
b(n) = -23 + 18n
Step-by-step explanation:
NOTE - This is an arithmetic sequence, so each number is increasing by addition. If you were in a geometric sequence, however, you'd be multiplying. This means that the explicit formula for the geometric sequence you'll be learning later on will be different.
The formula for explicit formula is b(n)=b(1)+d(n-1). The variable d represents the common difference and the a is whatever number of the term you are using.
Since you have b(1), you look at what your first term is. Plug -5 into a(1).
To find your common difference, find 13-(-5). This is 18, and adding it to the others you can see that it continues.
So, plugging in what you have so far it looks like b(n) = -5 + 18(n - 1)
All we need to do now is simplify.
1. Distribute: -5 + 18n - 18
2. Add like terms: -23 + 18n
Hope this helped and made sense lol.
