S (or answer D). The square and square root functions cancel each other out and effectively work as an absolute value function turning the input positive. So it doesn't matter what value S has to start with, its guaranteed to come out positive

in number 7, Is the exponent of (-1) n right? I thought that the exponent of (-1) is n-1 because it changed from n=0 to n=1, and if \((-1)^{n}\), there will be a change of sign between negative sign and positive sign.

The central processing unit (CPU) power in computers has increased significantly over the years. The CPU power in Macintosh computers has grown exponentially from 8 MHz in 1984 to 3400 MHz in 2013 (Source: Apple. The exponential function \(\displaystyle\${M}{\left({t}\right)}={7.91477}{\left({1.26698}\right)}^{{t}}{\left[{m}{a}{t}{h}\right]}\), where t is the number of years after 1984, an be used to estimate the CPU power in a Macintosh computer in a given year. Find the CPU power of a Macintosh Performa 5320CD in 1995 and of an iMac G6 in 2009. Round to the nearest one MHz.

Let C be the ellipse contained in the xy plane whose equation is \(\displaystyle{4}{x}^{{2}}+{y}^{{2}}={4}\), oriented clockwise. The force field F described by \(\displaystyle{F}{\left({x},{y},{z}\right)}={x}^{{2}}{i}+{2}{x}{j}+{z}^{{2}}{k}\), moves a particle along C in the same direction as the curve orientation, performing a W job. C as the surface boundary S: \(\displaystyle{z}={4}-{4}{x}^{{2}}-{y}^{{2}},{z}\ge{0}\) (with ascending orientation, that is, the component in the z direction equal to 1) and assuming \(\displaystyle\pi={3.14}\), we can state what:
a) It is not necessary to apply Stokes' Theorem, as C is a closed curve and therefore W = 0.
b) Inverting the orientation of the surface S, we can apply Stokes' Theorem and conclude that W = 12.56.
c) We can apply Stokes' Theorem and conclude that W = 6.28
d) We can apply Stokes' Theorem and conclude that W = 12.56.
