The cables of a suspension bridge are in the shape of a parabola, as shown in the figure. The towers supporting the cable are 900 feet apart and 60 feet high. If the cables touch the road surface midway between the towers, what is the height of the cable at a point 225 feet from the center of the bridge?
The cable is feet from the road surface at a point 225 feet from the center of the bridge.
(Simplify your anwer.)

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33

it is only things thain can be deafeated

step-by-step explanation:

this would be 35. 35 + 5 = 40. you take the known constant and subtract by the answer of the equation and you get y.
