A builder makes staircases where each step is 28\,\text{cm}28cm28, start text, c, m, end text long and rises 18\,\text{cm}18cm18, start text, c, m, end text so people don't trip. Every staircase has a stringer — a diagonal support connecting all of the steps. A certain staircase will have 666 steps. What is the length \ellℓell of the stringer for this staircase? Round your answer to the nearest tenth of a centimeter. \text{cm}cmstart text, c, m, end text

Each step has a diagonal aka hypotenuse h that satisfies

h² = 28² + 18² = 1108

The total length of  666 diagonals is

l =666h =  666 √1108 ≈ 22168.898213488195

22168.9 cm

The length of the stringer ℓ is approximately 199.7m

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
