Each cable of a of a suspension bridge is suspended in the shape of a parabola between two towers that are 120 meters apart and rise 20 meters above the roadway. The cables touch the roadway midway between the towers. a) Draw a sketch of the bridge. Locate the origin at the center of the roadway. Label the coordinates of all known points (the bases and the tops of the towers and the origin). b) Write an equation that models the cables. c) What is the height of the cables over the roadway at a distance of 40 meters from the center

answer: no

step-by-step explanation:

what is the answer?

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
