Parabola form : (y-k) = a(x-h)², where h and k are the vertex(h , k)
The vertex is given (2 , - 9), the equation of the parabola becomes:
y+9 = a(x-2)²
But we know this curve passes through (5, - 18)
Plug the respective values of x & y in the equation:
-18 +9 = a(5-2)² → - 9 = 9a & a = -9/9 and a= - 1
8 ( 12x + 4 ) = 96x + 32 8 ( 12x + 4 )
= 1920 + 32 OR = 8 ( 240 + 32 )
= 1952 = 1920 + 32
= 1952
8*12x = 96x 96*20 = 1920
8* 4 = 32 12*20 = 240
240*8 = 1920
26/52 times 26/52
Which is equivalent to 1/2 times 1/2
Which equals 1/4. Or 25%. Or 1:4. However you prefer
