Apattern of letter arrangements begins with the 3 steps below,
a
aba
abcba
what are the next 3 steps, how many letters are in the 3 above and how many letters are in the 10th step?

next 3 steps:

ABCDCBA
ABCDEDCBA
ABCDEFEDCBA

Patern: add 2 letters

1. 1
2. 3
3. 5
4. 7
5. 9
6. 11
7. 13
8. 15
9. 17
10. 19

The 10th step has 19 letters

the amount you'd have after the work is $1.55

step-by-step explanation:

you subtract 95% from $31.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
