Write an equation for a parabola in which the set of all points in the plane are equidistant from the focus and line F(-6,0); x=

Bogdan [553]

Step-by-step explanation:

Since we have a vertical directrix, the equation of the parabola is

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

Where p is the distance from the vertex to the directrix.

or the distance from the vertex to the focus.

Since we have a sideways parabola, let use the point for the directrix is (-6,0). So let find the midpoint of (-6,0) and (6,0). That would be our vertex.

$\frac{ - 6 + 6)}{2} = 0$

$\frac{0 + 0}{2} = 0$

So our vertex is (0,0).

So our equation become

${y}^{2} = 4px$

The distance from the focus and directrix is 6.

So p=6.

${y}^{2} = 24x$

So p is 6.

Since p is 6,

$\frac{ {y}^{2} }{24} = x$

Solve for y 48= 8/3y

blsea [12.9K]

Answer:

y = 18

Step-by-step explanation:

To find the value of y, you must multiply the fraction 8/3 by its reciprocal 3/8 to both sides. That means you do 48 times 3/8 to get your y value. Once you multiply you get 144/8 which simplifies to 18.

A spinner is separated into six equal sections, each with a different color. According to theoretical probability, how many time

Misha Larkins [42]

Answer:

you are expected to land on each color ten times in 60 spins

Step-by-step explanation:

probability of landing any color on any given attempt is 1/6 or 0.1667, since all colors are different, the probability for each is the same.

if you multiply the probability by 60 you will find the amount of time you will expect to land on each color

$\frac{1}{6}*60 =10$
