Decimals are ALWAYS tenths, hundredths, then thousandths.
So in this case the 2 will be in the tenths place
the 6 will be in the hundredths place
the 5 will be in the thousandths place.
Answer: y = (12-x)/(2x)
---------------------------------------------------------------
Work Shown:
2xy+x = 12
2xy+x-x = 12-x ... subtract x from both sides
2xy = 12-x
2xy/2x = (12-x)/(2x) ... divide both sides by 2x to get y all by itself
y = (12-x)/(2x)
If you take the point on the bridge directly beneath the lowest point on the cable to be the origin, then the parabola has equation
300 ft to either side of the origin, the parabola reaches a value of <em>y</em> = 90, so
Adding these together eliminates <em>b</em> and lets you solve for <em>a</em> :
Solving for <em>b</em> gives
So the parabola's equation is
150 ft away from the origin, the cable is at a height <em>y</em> of
ft above the bridge.
That's a parabola. Inside the parenthesis the x-3 affects the placement on the x axis. since is subtracting you move the vertex 3 to the right(because its backwards like that) There is no limit to the x, as it will slowly mom out forever even when its so steep that in reality you dont care, so domain is infinite or all real numbers. the parabola is positive so it moves up forever, but it never goes below its vertex on the x axis.
Domain=all real numbers
Range= all real numbers>or = 0
Can you give more context to the question so i can answer it?
