Help me find p please.

Question

(X-3.15)^2=4p(y-219.7981936)

Thanks!!!

Answer 1

( x - 3.15 ) ^ 2 = x ^ 2 - 2 * x * 3.15 + 3.15 ^ 2 = x ^ 2 - 6.3 x + 9.9225

( x - 3.15 ) ^ 2 = 4 p ( y - 219.7981936 )

x ^ 2 - 6.3 x + 9.9225 = 4 p ( y - 219.7981936 ) Divide both sides by 4

x ^ 2 / 4 - 6.3 x / 4 + 9.9225 / 4 = p ( y - 219.7981936 )

0.25 x ^ 2 - 1.575 x + 2,480625 = p ( y - 219.7981936 ) Divide both sides by ( y - 219.7981936 )

( 0.25 x ^ 2 - 1.575 x + 2,480625 ) / ( y - 219.7981936 ) = p

p = ( 0.25 x ^ 2 - 1.575 x + 2,480625 ) / ( y - 219.7981936 )
