Solve the quadratic equation by completing the square. QUESTION ATTCHED BELOW!!!!!!!!!!

Mariulka [41]

Answer:

x ≈ - 9.41, x ≈ - 6.59

Step-by-step explanation:

Given

x² + 16x + 62 = 0 ( subtract 62 from both sides )

x² + 16x = - 62

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(8)x + 64 = - 62 + 64

(x + 8)² = 2 ( take the square root of both sides )

x + 8 = ± $\sqrt{2}$ ( subtract 8 from both sides )

x = - 8 ± $\sqrt{2}$

Hence

x = - 8 - $\sqrt{2}$ ≈ - 9.41

x = - 8 + $\sqrt{2}$ ≈ - 6.59

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 required to inscribe an equilateral triangle.

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

WILL MARK BRAINLIEST ANSWER!!!!!!! Quadrilateral KLMN is similar to quadrilateral WXYZ. Write a proportion that must be true for

snow_tiger [21]

Answer:

Since, In Quadrilaterals KLMN and quadrilateral WXYZ,

Sides Kl, LM, MN and NK are corresponding to the sides WX, XY, YZ and ZW respectively.

Also, If two shapes are similar the ratio of their corresponding sides must be same are in same proportion,

Here, Quadrilateral KLMN is similar to quadrilateral WXYZ,

Therefore,

$\frac{KL}{WX}=\frac{LM}{XY}=\frac{MN}{YZ}=\frac{NK}{ZW}$

Which is the required proportion that must be true for the given figure.
