Answer:
Step-by-step explanation:
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:
m = 32g
Step-by-step explanation:
The proportion between m and g can be written ...
m = kg
where k is the constant of proportionality.
__
We can find its value by dividing by g:
k = m/g
Using any pair of corresponding values from the table, we find ...
k = 64/2 = 32
The relationship between m and g can be expressed by the equation ...
m = 32g
