1) What radius of a circle is required to inscribe an equilateral triangle with an area of 15.588 in2 and an altitude of 5.196 i
Andrej [43]
We know that
 the distance from the centroid of the triangle to one of the vertices is the radius of the circle <span>required to inscribe an equilateral triangle.

[distance </span>centroid of the triangle to one of the vertices]=(2/3)*h
h=the <span>altitude  of the equilateral triangle-----> 5.196 in
so
</span>[distance centroid of the triangle to one of the vertices]=(2/3)*5.196
[distance centroid of the triangle to one of the vertices]=3.464 in----> 3.5 in

the radius is equal to the distance of the centroid of the triangle to one of the vertices
hence
the radius is 3.5 in

the answer is
the radius is 3.5 in

100pts: Why was obsidian used to make scalpels?
Margaret [11]

Answer:

Research also confirms that incisions carried out with obsidian produce narrower scars and fewer inflammatory cells. This is because on cellular level, obsidian knife cuts between cells rather than tearing it in case of a steel knife, hence, a sharper cut allows the wound to heal more easily with negligible scarring.

Solving quadratic equations with complex solutions<br> solve x^2-3x=-8
abruzzese [7]

x^2-3x=-8\\\\x^2-3x+2.25=-5.75\\\\(x-1.5)^2=-5.75\\x-1.5=\pm i\sqrt{5.75}\\\boxed{x=1.5 \pm i\sqrt{5.75}}

Not the prettiest but you can simplify

The value of y varies directly with x, and y = 18 when x = 12. find y when x = 132.
sveta [45]
This would be 198 because 12 times 1.5 equals 18 so when you multiply 132 by 1.5 you get 198
