Before answering this question let us know what are net and total areas.
Now let us look at first part of our question. Net area of our region will be equal to total area of region when the whole region lies above x axis because then our whole region is positive.
The net area of a region will differ from the total area of the region when some part of our region is above x-axis and some part of region is below x-axis. This is because we have to subtract area of region which is below x-axis from area above x-axis to get net area.
ANSWER
EXPLANATION
The exponential function that models cell duplication in the lab is given as
We want to determine the time it will take for the cells to increase to
In other words, we want to find the value of
when
This gives us the equation,
Recall that,
We apply this property to the right hand side to obtain,
This implies that,
We divide both sides by 4 to get,
We take the antilogarithm of both sides to base 10 to get,
This implies that,
to the nearest hundredth.
