The profile of the cables on a suspension bridge may be modeled by a parabola. the central span of the bridge is 1230 m long and 140 m high. the parabola y equals 0.00037 x squared gives a good fit to the shape of the cables, where startabsolutevalue x endabsolutevalue less than or equals 615, and x and y are measured in meters. approximate the length of the cables that stretch between the tops of the two towers.

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

1. perpendicular

2. parallel

3. perpendicular

he answer is x=1x3 because x=1 to x=3
