The coordinate plane shows an arch that forms part of a bridge. Each unit represents 1 foot. Enter an equation of the quadratic function that models the arch, where x is the horizontal distance in feet from
the left end and y is the height in feet for a given value of x. Complete the explanation of your answer.

555.99.

step-by-step explanation:

hope this

step-by-step explanation:

-1   1/6.   you dont subtract the denominators

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
