a wind up robot can travel 20m on a single wind. how many times will it need to wind to cover a distance of half a mile?

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

2,160 π
