What is the equation of the parabola with focus (3, 0) and directrix x = –3?

nikitadnepr [17]

Answer:

x = $\frac{1}{12}$ y²

Step-by-step explanation:

Any point (x, y ) on the parabola is equidistant from the focus and the directrix

Using the distance formula, then

$\sqrt{(x-3)^2+(y-0)^2}$ = | x + 3 |

Squaring both sides

(x - 3)² + y² = (x + 3)² ← expanding both sides

x² - 6x + 9 + y² = x² + 6x + 9 ← subtract x² + 6x + 9 from both sides

- 12x + y² = 0 ( subtract y² from both sides )

- 12x = - y² ( divide both sides by - 12 )

x = $\frac{1}{12}$ y²

Answer:

1 pound- $4.7
2 pounds- $9.4
3 pounds- $14.1
4 pounds- $18.8

Step-by-step explanation:

Just hardware's prices are 0.30 greater per pound, so the equation would be y=4.7x. Substitute x in for each of the values to get the prices above.
