Answer:

x=2√3

Step-by-step explanation:

Let's solve your equation step-by-step.

x2

x2=12

Step 3: Take square root.

x=±√12

x=2√3 or x=−2√3

Which equation represents a parabola that has a focus of (0 0) and a directrix of y = 2
mel-nik [20]

ANSWER

x ^{2}  =  - 4(y - 1).

EXPLANATION

Since the parabola has the (0, 0) and the directrix at y=2.

The equation is of the form

{(x - h)}^{2}  =  - 4p(y - k)

where (h,k) is the vertex.

The vertex is half way between the directrix and the focus.

The vertex will be at (0,1)

and is the distance from the vertex to the focus which is 1.

{(x - 0)}^{2}  =  - 4(1)(y - 1)

x ^{2}  =  - 4(y - 1)

Find the circumference of each circle. Use 3.14 for the value of π . Round answer to the nearest tenth.
kvv77 [185]

Answer:

C=9.4\pi meters

Step-by-step explanation:

Recall to find the circumference of a circle the formula is C=\pi d or C=2\pi r.

We start by substituting 4.7m for r in the second circumference formula.

C=2\pi r\\C=2\pi (4.7)\\C=9.4\pi. We input this value of r into the area formula.

Identify the vertex of the quadratic function in standard form y=2x^2 -16x+31
lapo4ka [179]

Answer:

(4,1)

Step-by-step explanation:

The vertex of the quadratic can be found using -b/2a. The vertex is the point (-b/2a, f(-b/2a)).

To find the x coordinate of the quadratic, define its a,b, and c. The quadratic has a = 2, b=-16, and c=31. Then -b/2a is -(-16)/2(2) = 16/4 = 4.

To find the y-coordinate, input the x=4 and solve for y.

y=2(4)^2-16(4)+31\\y=2(16)-64+31\\y=32-64+31\\y=1

The vertex is (4,1).
