Answer:
Step-by-step explanation:
<u>Circumference formula:</u>
- C = 2πr,
- where π = 3.14, r - radius
1.
- C = 18.8 in
- 2*3.14r = 18.8
- 6.28r = 18.8
- r = 18.8/6.28
- r = 2.99 ≈ 3 in
2.
- C = 22 in
- 6.28r = 22
- r = 22/6.28
- r ≈ 3.5 in

Rachel needs to work 64 hours to earn 1 vacati on day
I don't like dividing polynomials so I'm going to set x=1 and try them out.
(1-2-14+3)/4 = -3
Of the choices, only D gives -3 when x=1
~~~~~~~~~~~~~~~~~~~~~~
That's as much test-taking as math. If we were to divide
x^2 - 5x + 1
-------------------------------
x + 3 | x^3 - 2x^2 - 14x + 3
x^3 + 3x^2
-5x^2 - 14x
5x^2 + 15x
x + 3
x + 3
More work, still choice D
