Asked by Alan

I already did this problem but i decided to check my self since my answer wasn't withthe status quo of the rest of the answers i checked twice and got the same answer. But will someone double check me.

The designers fo the Parthenon, a Greek Temple completed in 432 B.C., utilized the golden ration. The outline of its face fits into a golden rectangle, in which the length varies directly as its height in the ration 1.618 to 1. The length of the temple was about 31m what was the original height of the parthenon.

The answer I came up with was 50.16 m Am i right???
Answered by Damon
No, not right, length must be greater than height here.

length = (1.618/1) * height

31 = 1.618 * height

height = 31 / 1.618

How do I find the axis of symmetry in a quadratic equation? And how do I put the equation in vertex form?

5 x^2 + 10 x - 20 = y
first divide everything by 5, the coef of x

x^2 + 2 x - 4 = y/5
now add 4 to both sides

x^2 + 2 x = y/5 +4
now take half the coef of x, square it, and add to both sides
(2/2)^2 =1
so
x^2 + 2 x + 1 = y/5 + 5
NOW the left is
(x+1)^2 = y/5 + 1

symmetry to the right and left of x = -1 where the left is 0
so the x coordinate of the vertex is x = -1

What is y then?
y/5 + 1 = 0
y = -1(5) = -5
so the vertex is at
