The value of P is 3
Given general formula for a parabola is x2 = 4py ………….(a)
Also given that x2 = 12y …………..(b)
Equating (a) and (b), we get
x2 = 4py ≅ x 2 = 12y
⇒ 4py = 12y
Canceling the 'y' on either sides, we get
⇒ 4p= 12 p= 3
When the general formula for a parabola is x2 = 4py. The value of p in the equation x2 = 12y is 3.
In mathematics, a parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped. It fits several superficially different mathematical descriptions, which can all be proved to define exactly the same curves. One description of a parabola involves a point and a line

Answer:
g(4a) = 8a^2 -20a +3.5
Step-by-step explanation:
Put 4a where x is and simplify.
g(x) = 0.5x^2 -5x +3.5
g(4a) = 0.5(4a)^2 -5(4a) +3.5
= 0.5(16a^2) -20a +3.5
g(4a) = 8a^2 -20a +3.5
Answer:
Total chairs = 18×22= 396
so no. of extra chairs need = 468-396 = 72
Now( 72/18) rows = 4 rows
Therefore 4 more rows are needed here
