The cables of a suspension bridge are in the shape of a parabola, as shown in the figure. The towers supporting the cable are 300 feet apart and 100 feet high. If the cables touch the road surface midway between the towers, what is the height of the cable at a point 75 feet from the center of the bridge? The cable is feet from the road surface at a point 75 feet from the center of the bridge. (Simplify your answer.) 1

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.

step-by-step explanation:

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
