Steve repairs elevators. when he is called to a job he uses the stairwell to go to the floor on which the elevator is located. In the Modis building, he climbs 22 steps for every 15 feet of horizontal travel. In the Sears tower, he climbs 17 steps for every 7 feet of horizontal travel. Part A: What is the rate of change for each stairwell? Part B: Which stairwell will be easier to climb? Explain your reasoning. Can someone break it down and break it step by step?

step-by-step explanation:

answer

you start with $5 and save $10 a week until you have at least $45wer

step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
