<span>\int_c\vec f\cdot d\vec r, in two ways, directly and using stokes' theorem. the vector field \vec f = 5 y\vec i - 5 x\vec j and c is the boundary of s, the part of the surface z = 16 -x^2-y^2 above the xy-plane, oriented upward.</span>
Answer:
d
Step-by-step explanation:
It would cost $26 because 3x8=24. 3/1/3=1. so 1/3=$1.
Answer:
x = 5
Step-by-step explanation:
8x-9=7x+6-2x
We move all terms to the left:
8x-9-(7x+6-2x)=0
We add all the numbers together, and all the variables
8x-(5x+6)-9=0
We get rid of parentheses
8x-5x-6-9=0
We add all the numbers together, and all the variables
3x-15=0
We move all terms containing x to the left, all other terms to the right
3x=15
x=15/3
x = 5
You find the circumference is 2PIr
so radius is half of the diameter so 7/2=3.5
pi= 3.14
2*3.14=6.28
6.28*3.5= 21.98
