Marla is running clockwise around a circular track. she runs at a constant speed of 4 meters per second. she takes 46 seconds to complete one lap of the track. from her starting point, it takes her 12 seconds to reach the northernmost point of the track. impose a coordinate system with units in meters, the center of the track at the origin, and the northernmost point on the positive y-axis. (round your answers to two decimal places.) (a) give marla's coordinates at her starting point.
a dilation is a type of transformation that enlarges or reduces a figure by a scale factor,
in the dilation about origin by a scale factor k,
the coordinates of the transformed figure can be get by the following rule,
here k = 4,
thus, the dilation rule will be,
44 is the answer to this
its opposite reciprocal, mean that 3/1 (which is 3) will have the numerator swapped with its denominator.
so basically 3/1 would turn into 1/3
now the sign will be the opposite as well.
so since 3 is positive, the new slow should be a negative.
