Suppose a railroad rail is 2 kilometers and it expands on a hot day by 19 centimeters in length. approximately how many meters would the center of the rail rise above the ground?

rail rise approximately 0.19 m above the ground

Step-by-step explanation:

as we know that

1m=100cm

and 1cm= m

similarly

19cm=m

19cm=0.19m

rail rise approximately 0.19 m above the ground

heyyy

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
