\[\begin{array}{|c|c|}\hline \text{Wind (mph)}&\text{Wind-Chill} (^{\circ}F)\\ \hline 5&25\\ \hline 10&21\\ \hline 15&19\\ \hline 20&17\\ \hline 25&16\\ \hline 30&15\\ \hline 35&14\\ \hline 40&13\\ \hline 45&12\\ \hline 50&12\\ \hline 55&11\\ \hline 60&10\\ \hline \end{array}\]
The table gives the wind chill temperature when the outside temperature is \(\displaystyle{30}^{{\circ}}{F}\).
a. Use x as the wind speed and create a quadratic model for the data.
b. At what wind speed does the model estimate that the wind chill will be \(\displaystyle{14}^{{\circ}}{F}\)?
c. Is the model found in part (a) valid for \(\displaystyle{x}{>}{63}\)? Explain

Write the expression in rectangular form, \(\displaystyle{x}+{y}{i}\), and in exponential form \(\displaystyle{r}{e}^{{{i}\theta}}\).
\(\displaystyle{\left(\sqrt{{{13}}}-{i}\right)}^{{{4}}}\)
The rectangular form of the given expression is ?, and the exponential form of the given expression is ? (Simplify your answers. Use integers or decimals for any numbers in the expressions. Round the final answer to three decimal places as needed intermediate values to four decimal places as needed.)
