Let D be a region of area 9 located in xy-plane. Let S be the surface above D given by z = 4x + 7y + 2, where (x, y) ∈ D. Find the surface area of S. Area(S) =
Answer entry help:
1. No blank spaces are allowed in the answer fields
2. If your answer Area(S) = Z please write only Z in the answer box. Note that Area(S) = is already written. Thus, if you put Area(S) = Z in the answer box, the system will read this as Area(S) = Area(S) = Z and will treat as a wrong answer.
3.
Write v*z for v · z (multiplication of v by z )
Write v^(z) for v^z (parenthesis are required)
Write sqrt(z) for √ z (parenthesis are required)
