Answer:
The absolute error of the measurement is 0.25 inches
Step-by-step explanation:
we know that
The absolute error of a measurement is equal to one half the unit of measure.
In this problem we have
7.5 inches
The measurement is given by 0.5 inches
So
the absolute error of this measurement is

Therefore
the exact measurement could be between
7.5 (+/-) 0.25 in
That is, between 7.25 in and 7.75 in
Answer:
The slope is "Undefined"
Step-by-step explanation:
You want to find the time <em>t</em> such that

Divide both sides by $200 :

Take the logarithm of both sides:

Divide both sides by 0.04 and solve for <em>t</em> :
