The height h above the roadway of the main cable of the Golden Gate Bridge can be modeled by the function h(x) =1/9000x2 - 7/15x
julia-pushkina [17]
H(x) = 1/9000x^2 - 7/15x + 500 = 1/9000(x^2 - 4200x + 4500000) = 1/9000(x^2 - 4200x + 4410000 + 90000) = 1/9000(x - 2100)^2 + 1/9000(90000) = 1/9000(x - 2100)^2 + 10

h(x) = 1/9000(x - 2100)^2 + 10

I’m confused on this one
ad-work [718]

The question is "What is the scale of the model to the actual statue"


That means you must put 2/15.


2 being the model


15 being the actual statue


Take that fraction and equal is to 1/x.


Multiply 15 to 1 and 2 to x.


In the end, to solve, you divide 15 by 2x.


The answer is X=7.5


1 : 7.5
