(a)
We have been given an equation 
. Upon taking derivative of this equation with respect to x on both the sides, we get:
(b)
In order to write the equation of tangent line, we need to find the slope of the line. We know that point (3,11) lies on the graph. Therefore, we write the slope of the tangent as:
Therefore, equation of tangent line is:
(c)
We know that slope of tangent is given as 
. The tangent will be vertical when denominator of slope is zero, that is:
Collapsed stars bigger than our sun they have to have a certain mass
The Forensic Anthropology Facility studies THE DECOMPOSITION OF HUMAN REMAINS.
The anthropology facility is a research facility where decomposition of human bodies can be studied in a variety of settings. It also serves as a resource for forensic anthropology students and researchers.
