Suppose that surface σσ is parameterized by r(u, v)=⟨ucos(6v),usin(6v),v⟩r(u, v)=⟨ucos(6v),usin(6v),v⟩, 0≤u≤70≤u≤7 and 0≤v≤1π30≤v≤1π3 and f(x, y,z)=x2+y2+z2f(x, y,z)=x2+y2+z2. set up the surface integral (you don't need to evaluate it). ∫σ∫f(x, y,z)ds=∫r∫f(x(u, v),y(u, v),z(u, v))∥∥∥∂r∂u×∂r∂v∥∥∥da∫σ∫f(x, y,z)ds=∫r∫f(x(u, v),y(u, v),z(u, v))‖∂r∂u×∂r∂v‖da

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
