a distance between points a and b is measured and recorded as 545.67 ft, using a 100' tape that has a certified standard length of 100.02 ft. what is the "true" distance between a and b?

Final answer:

The true distance between points A and B is approximately 545.67 ft. This situation involves the concept of a linear scale error. The tape's certified standard length differs from its actual length. To find the "true" distance between points A and B, you can use the ratio of the certified length of the tape to the actual length of the tape.

Step-by-step explanation:

To find the true distance between points A and B, we can use the concept of proportionality. Let's call the true distance x. We can set up a proportion using the measurements given: 100 ft is to 100.02 ft as 545.67 ft is to x. Using the cross-product property of proportions, we can multiply the extremes and set them equal to the product of the means: 100 * x = 545.67 * 100.02. Simplifying the equation, we find that the true distance between A and B is approximately 545.67 ft. Note that the difference between the certified standard length and the measured length is negligible in this case.
