Find the vertex of this parabola: y=-4x^2+8x-12
tatiyna
<span>The vertex of the parabola is the highest or lowest point of the graph. 

</span><span>y=-4x^2+8x-12 = -4 (x^2 -2x +3) 

Lets work with this now: </span>x^2 -2x +3

x^2 -2x +3 -> what is the closeset perfect square? 
x^2 -2x +1 = (x-1)^2
So
x^2 -2x +3 = (x-1)^2 +2

Replacing to original 
y=-4x^2+8x-12 = -4 (x^2 -2x +3) = -4 ((x-1)^2 +2) = -4 (x-1)^2 - 8

The min or max point is where the squared part = 0
So when x=1 , y= -4*0-8=-8

This will be the max of the parabola as there is - for the highest factor (-4x^2)

The max: x=1, y= -8

Elise walks diagonally from one corner of a square plaza to another. Each side of the plaza is 50 meters. What is the diagonal d
jolli1 [7]

Answer:

70.7 meters.

Step-by-step explanation:

We have been given that Elise walks diagonally from one corner of a square plaza to another. Each side of the plaza is 50 meters.

Since we know that diagonal of a square is product of side length of square and \sqrt{2}. So we will find diagonal of our given square plaza by multiplying 50 by \sqrt{2}.

\text{Diagonal distance across the plaza}=50\times \sqrt{2}

\text{Diagonal distance across the plaza}=50\times 1.414213562373095

\text{Diagonal distance across the plaza}=70.71067811865475\approx 70.7

Therefore, diagonal distance across the plaza is 70.7 meters.

I need help please ​
Naddik [55]

Answer:

Step-by-step explanation:

7) ∠1  + 30 = 180                {linear pair}

            ∠1 = 180 - 30

            ∠1 = 150

8)  ∠2 = 30    {Vertically opposite angles are congruent}

9) In ΔLMN,

∠L + ∠N + ∠M = 180   {angle sum property of triangle}

50 + 30 + ∠M = 180

       80 + ∠M = 180

                ∠M = 180 - 80

                ∠M = 100°

10) Sum of exterior angle of a triangle equals to sum of opposite interior angles.

∠B + ∠A = ∠BCD

30 +   ∠A = 80

        ∠A  = 80 - 30

      ∠A = 50
