Answer:

24

P: parentheses (12 - 8) = 4

E: exponents (3^2) = 9

M: multiplication (12-8)/2 * 4 = 8

D: division (12-8)/2 = 2

A: addition (7 + 9 + 8) = 24

S: subtraction (blank)

Following the order of operations, our final answer is: 24

Which shows a way to take apart 8 .ans are. 9-9=0. 8-7=1. 9-8=1. 8+8=16.
Sergio039 [100]
<span>To take appart 8 means to subtract 8 from a number and then you will have two parts one with the number 8 and the other with the difference. So, if you want to take appart 8 from 9, you make 9 - 8 = 1. Which means that you can have 8 and 1 sperated from 9. So the answer is the third option 9 - 8 = 1.</span>

Given that curl F = 2yi – 2zj + 3k, find the surface integral of the normal component of curl F (not F) over (a) the open hemisp
Dimas [21]

Use Stokes' theorem for both parts, which equates the surface integral of the curl to the line integral along the surface's boundary.

a. The boundary of the hemisphere is the circle x^2+y^2=9 in the plane z=0, where the curl is \mathrm{curl}\vec F=2y\,\vec\imath+3\,\vec k. Green's theorem applies here, so that

\displaystyle\iint_S\mathrm{curl}\vec F\cdot\mathrm d\vec S=\int_{\partial S}\vec F\cdot\mathrm d\vec r=3\int_{x^2+y^2=9}\mathrm d\vec r

which means the value of the line integral is 3 times the area of the circle, or 27\pi.

b. The closed sphere has no boundary, so by Stokes' theorem the integral is 0.
