Given the equation 4x2 − 8x + 20 = 0, what are the values of h and k when the equation is written in vertex form a(x − h)2 + k =
GenaCL600 [577]

Answer:

The correct option is:

h = 1, k = 16

Step-by-step explanation:

y=4x^2-8x+20 =0

It is a quadratic formula in standard form:

ax^2+bx+c

where a = 4 , b = -8 and c=20

The vertex form is:

a(x − h)2 + k = 0

h is the axis of symmetry and (h,k) is the vertex.

Calculate h according to the following formula:

h = -b/2a

h= -(-8)/2(4)

h = 8/8

h = 1

Substitute k for y and insert the value of h for x in the standard form:

ax^2+bx+c

k = 4(1)^2+(-8)(1)+20

k = 4-8+20

k=-4+20

k = 16

Thus the correct option is h=1, k=16....

Tv Is 40 inches in length and 24 inches in width how tall is it
Sedaia [141]

Answer

<em>TV screens are measured on the diagonal  </em>

<em>. In this specific case the TV is shaped like a rectangle , whose diagonal is 40 i n c h e s and its width is 24 i n c h e s : w = </em>

<em>24 i n d = 40 i n  </em>

<em>Then , the sides of the rectangle and its diagonal form a right triangle .  </em>

<em>Therefore , we can determine the height ( l )  </em>

<em>if we can apply the Pythagorean theorem: d 2 = l 2 + w 2  </em>

<em>So , solving for l : l = √ d 2 − w 2  </em>

<em>Thus , substituting: l = √ ( 40 ) 2 − ( 24 ) 2  </em>

<em>Simplifying: d = √ 1024 = 32 i n  </em>

<em>Therefore  </em>

<em>, the height of the TV is:  </em>

<em>32 i n </em>
