Alcohol would be more suitable for making measurements in a -60 degree laboratory, since its boiling point is 78 degrees and its freezing point is -80 degrees, meaning alcohol will not freeze in a -60 degree environment.

Mercury on the other hand, has a freezing point of -39. Thus, it will freeze in a -60 degree environment, making it not suitable for use in this laboratory.

Find x value for the point that splits segment CD in half if point C is located at (-2,4) and point D is located (3,7)

ella [17]

Now, if "x" splits CD in two equal halves, that means "x" is the midpoint of CD

$\bf \textit{middle point of 2 points }\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
C&({{ -2}}\quad ,&{{ 4}})\quad 
% (c,d)
D&({{ 3}}\quad ,&{{ 7}})
\end{array}\qquad
% coordinates of midpoint 
\left(\cfrac{{{ x_2}} + {{ x_1}}}{2}\quad ,\quad \cfrac{{{ y_2}} + {{ y_1}}}{2} \right)
\\\\\\
x=\left( \cfrac{3-2}{2}~,~\cfrac{7+4}{2}\right)$

To construct the regular hexagon, the radius length AB is used to mark the vertices of the hexagon. Can this method be used to m

True [87]

No, it cannot be used to create other regular inscribed polygons.

This plan only works with a hexagon. If you inscribe a square into a circle, the lengths of the sides will not be equal to the radius.
