1.50d is the right answer since we don't know how many drinks there are
In science, rate is a<span> quantity measured with respect to another measured quantity. For the data given, we get the rate of each by calculating the slope. We do as follows:
Megan's rate = 12 - 4.5 / 4 -1 = 2.5 inches per week
Suzanne's rate = 11 - 5 / 4-1 = 0.5 inches per week
Therefore, the plant that grew at a faster rate would be </span><span>Megan’s at 2.5 inches per week.</span>

Curl is defined as:

Which can be rewritten as:

This is because C1 lies on the xy plane and thus it's unit vector will be
.
By similar arguments the rest will follow too.
Now, area of each circle will be: 
Therefore, Curl, as per our definition will be:

Thus, Curl=
Which is the required answer.
