Question 1161504: A bicyclist is competing in a tournament. He is currently in a very hilly part of the tournaments cour. For his current hill, his height in meters over time in minutes is modelled by the function f(x)=-0.00075x^2 - 0.5825x + 17.269 determine the bicyclists instantaeous rate of change at x = 100 round you answer to 3 significant figures.

f%28x%29=-0.00075x%5E2+-+0.5825x+%2B+17.269+
determine the bicyclists instantaneous rate of change at x+=+100
f%28x%29=-0.00075%2A100%5E2+-+0.5825%2A100%2B+17.269+
f%28x%29=-0.00075%2A10000+-+58.25%2B+17.269+
f%28x%29=-+7.5++-+58.25%2B+17.269+
f%28x%29=-48.481+

This post contains  TOOOOOOO  MANY  ERRORS  in its English text,  that make it  NONSENSICAL.

The major question  "determine the bicyclists instantaeous rate of change"  is posed  INCORRECTLY
and  CAN  NOT  be answered as it is posed.

The   "answer"  by  @MathLover1  MAKES  no  SENSE.
