Question

A diameter of 380 feet and a maximum depth of 50 feet. Find the equation of this parabola with equation y= ax^2.

Answer 1

V=(0,50)

Answer 2

by diameter do you mean latus rectum

Answer 3

190=a x 50^2 i think since x=(-190, 50) and (190,50)

Answer 4

kkkkkkkkkkk

Answer 5

then i get y=19/250 = a?

Answer 6

maybe x=190 and 50 is y so equation could be 50=a * 190^2
