Answer:
The standard parabola
y² = -18 x +27
Length of Latus rectum = 4 a = 18
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given focus : (-3 ,0) ,directrix : x=6
Let P(x₁ , y₁) be the point on parabola
PM perpendicular to the the directrix L
SP² = PM²
(x₁ +3)²+(y₁-0)² =
x₁²+6 x₁ +9 + y₁² = x₁²-12 x₁ +36
y₁² = -18 x₁ +36 -9
y₁² = -18 x₁ +27
Length of Latus rectum = 4 a = 4 (18/4) = 18
The answer is A
thats easy
but thanks 4 the points
A = 48
In this equation, we can factor out the expression . If we do so, the expression becomes:
We can simplify to get:
and get:
Therefore, A = 48
