Answer:
y = - 
(x - 1)² + 2
Step-by-step explanation:
Any point (x, y) on the parabola is equidistant from the focus and the directrix.
Using the distance formula
= | y - 6 |
Square both sides
(x - 1)² + (y + 2)² = (y - 6)² ( expand the factors in y )
(x - 1)² + y² + 4y + 4 = y² - 12y + 36 ( subtract y² - 12y from both sides )
(x - 1)² + 16y + 4 = 36 ( subtract 4 from both sides )
(x - 1)² + 16y = 32 ← subtract (x - 1)² from both sides )
16y = - (x - 1)² + 32 ( divide all terms by 16 )
y = - (x - 1)² + 2

Answer:
1/15
Step-by-step explanation:
Answer: 52.9 quarts
Step-by-step explanation:
From the question, we are informed to calculate the number of quarts that are in 50 liters.
1 liter = 1.057 liquid quarts
50 liters will now be:
= 50 × 1.057
= 52.85
= 52.9 quarts
As we can see in the given figure, Angles A and B are equal. therefore their opposite sides will be equal to one another, that is ~
now, let's plug the values of AB and BC in terms of x and equate them to find the value of x ~
now , let's find the measure of side AC ~
that is ~
