S(r) = 2pi*r*h + 2pi*r^2
S ' (r) = 2pi*h + 2*2*pi*r .... differentiate with respect to r
S ' (r) = 2pi*h + 4pi*r
S ' (3) = 2pi*h + 4pi*3 ... plug in r = 3
S ' (3) = 2pi*h + 12pi
S ' (3) = 2pi*2 + 12pi .... plug in h = 2
S ' (3) = 4pi + 12pi
S ' (3) = 16pi
---------------

Answer:
Generalizability is applied by researchers in an academic setting. It can be defined as the extension of research findings and conclusions from a study conducted on a sample population to the population at large. While the dependability of this extension is not absolute, it is statistically probable. Because sound generalizability requires data on large populations, quantitative research -- experimental for instance -- provides the best foundation for producing broad generalizability. The larger the sample population, the more one can generalize the results. For example, a comprehensive study of the role computers play in the writing process might reveal that it is statistically probable that students who do most of their composing on a computer will move chunks of text around more than students who do not compose on a computer.

Answer: 8/3 and -9/4
Step-by-step explanation:
1. ![\frac{2^{3}}{3} = \frac{2 * 2 * 2}{3} = \frac{8}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%5E%7B3%7D%7D%7B3%7D%20%3D%20%5Cfrac%7B2%20%2A%202%20%2A%202%7D%7B3%7D%20%3D%20%5Cfrac%7B8%7D%7B3%7D)
2. In this problem, when raising a whole fraction to a power, you must both raise the numerator and denominator to that power.
![-(\frac{3}{2})^2 = -(\frac{3^2}{2^2}) = -(\frac{9}{4}) = -\frac{9}{4}](https://tex.z-dn.net/?f=-%28%5Cfrac%7B3%7D%7B2%7D%29%5E2%20%3D%20-%28%5Cfrac%7B3%5E2%7D%7B2%5E2%7D%29%20%3D%20-%28%5Cfrac%7B9%7D%7B4%7D%29%20%3D%20-%5Cfrac%7B9%7D%7B4%7D)
