Write the equation of the parabola in vertex form. Vertex: (−4,6); Point: (−2,−2)

gtnhenbr [62]

Answer:

y = - 2(x + 4)² + 6

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k ) = (- 4, 6 ) , thus

y = a(x - (- 4) )² + 6 , that is

y = a(x + 4)² + 6

To find a substitute (- 2, - 2) into the equation

- 2 = a(- 2 + 4)² + 6 ( subtract 6 from both sides )

- 8 = a(2)² = 4a ( divide both sides by 4 )

- 2 = a , thus

y = - 2(x + 4)² + 6 ← equation in vertex form

The image below is a triangle drawn inside a circle with center O:

Alex17521 [72]

The area of a circle is,

$\pi \: \times r ^{2}$

So pi times the radius squared.

~~

To find the radius we half to divide the diameter by 2 since the radius is half of the diameter.

The diameter is the line that passes through the the center of the circle going from one side of the circle to the other which is 4 in this case.

Half of 4 is 2 meaning 2 is our radius.

~~

Plug in the numbers and get,

$3.14 \times 2^{2}$

~~

I hope that helps you out!!
