Kyler-Project

The gateway arch- Chapter 12 project The Gateway arch is the tallest structure in the state of Missori. It is 192 meters tall and 170 meters wide. The cost of this structure was around the price of 13 million dollars. Now that would be about 90 million dollars. Construction on the arch began Febuary/12/1963 and it ended October/28/1965. It is made out of mostly glass and steel. It was later opened to the public in 1967. This graph shows the height and the width in meters.Below the graph there is an exel form of the equation.Here are some other forms. Standard Form: y =0.026x^2+4.517x+1 Vertex Form: y-170=0.026(4.517-192)^2 Factored Form:y =(x-192)(x-170) I got my equations by using the quadratic formula. This formula is y=ax^2+bx+c a^2= 0.026^2 b = 4.517 c = 1 I put in these numbers into the quadratic formula in standard form, vertex form, and factored form.

My y intercepts is 0 My x intercepts is 0 and 170

the formula to a discrimant is b^2 = 4bc
