### Instruction:
Let
$$p(x,y) = a_0 + a_1x + a_2y + a_3x^2 + a_4xy + a_5y^2 + a_6x^3 + a_7x^2y + a_8xy^2 + a_9y^3.$$Suppose that
\begin{align*}
p(0,0) &=p(1,0) = p( - 1,0) = p(0,1) = p(0, - 1)= p(1,1) = p(1, - 1) = p(2,2) = 0.
\end{align*}There is a point $(r,s)$ for which $p(r,s) = 0$ for all such polynomials, where $... | Observe that \begin{align*}
p(0,0) &= a_0 = 0\\
p(1,0) &= a_0 + a_1 + a_3 + a_6 = a_1 + a_3 + a_6 = 0\\
p(-1,0) &= -a_1 + a_3 - a_6 = 0.
\end{align*}Adding the above two equations gives $a_3 = 0$, and so we can deduce that $a_6 = -a_1$. Similarly, plugging in $(0,1)$ and $(0,-1)$ gives $a_5 = 0$ and $a_9 = -a_2$. Now,... |

### Instruction:
Find the area of the region described by $x \ge 0,$ $y \ge 0,$ and
\[100 \{x\} \ge \lfloor x \rfloor + \lfloor y \rfloor.\]Note: For a real number $x,$ $\{x\} = x - \lfloor x \rfloor$ denotes the fractional part of $x.$ For example, $\{2.7\} = 0.7.$
### Response:
| Let $n = \lfloor x \rfloor,$ and let $\{x\} = (0.x_1 x_2 x_3 x_4 \dots)_{10},$ so the $x_i$ are the decimal digits. Then the given condition becomes
\[\lfloor y \rfloor \le 100 \{x\} - \lfloor x \rfloor = (x_1 x_2.x_3 x_4 \dots)_{10} - n.\]Since $\lfloor y \rfloor$ is an integer, this is equivalent to

### Response:
| Let $\mathbf{v} = \begin{pmatrix} x \\ y \\ z \end{pmatrix},$ and let $\mathbf{p}$ be the projection of $\mathbf{p}$ onto plane $P.$ Then $\mathbf{v} - \mathbf{p}$ is the projection of $\mathbf{v}$ onto the normal vector $\mathbf{n} = \begin{pmatrix} 1 \\ 1 \\ -1 \end{pmatrix}.$

Rectangle $ABCD$ and a semicircle with diameter $AB$ are coplanar and have nonoverlapping interiors. Let $\mathcal{R}$ denote the region enclosed by the semicircle and the rectangle.

Let this point be O. Let $h$ be the length of $AD$.
Rescale everything by 42, so $AU = 2, AN = 3, UB = 4$. Then $AB = 6$ so $OA = OB = 3$.
Since $ON$ is a radius of the semicircle, $ON = 3$. Thus $OAN$ is an equilateral triangle.

Let $P(z) = z^8 + \left(4\sqrt{3} + 6\right)z^4 - \left(4\sqrt{3} + 7\right)$. What is the minimum perimeter among all the $8$-sided polygons in the complex plane whose vertices are precisely the zeros of $P(z)$?
### Response:
| First, we can factor $P(z) = z^8 + (4 \sqrt{3} + 6) z^4 - (4 \sqrt{3} + 7)$ as
\[P(z) = (z^4 - 1)(z^4 + 4 \sqrt{3} + 7).\]The solutions to $z^4 - 1 = 0$ are 1, $-1,$ $i,$ and $-i$.
If $z^4 + 4 \sqrt{3} + 7 = 0,$ then
