<span>Let r(x,y) = (x, y, 9 - x^2 - y^2)
So, dr/dx x dr/dy = (2x, 2y, 1)
So, integral(S) F * dS
= integral(x in [0,1], y in [0,1]) (xy, y(9 - x^2 - y^2), x(9 - x^2 - y^2)) * (2x, 2y, 1) dy dx
= integral(x in [0,1], y in [0,1]) (2x^2y + 18y^2 - 2x^2y^2 - 2y^4 + 9x - x^3 - xy^2) dy dx
= integral(x in [0,1]) (x^2 + 6 - 2x^2/3 - 2/5 + 9x - x^3 - x/3) dx
= integral(x in [0,1]) (28/5 + x^2/3 + 26x/3 - x^3) dx
= 28/5 + 40/9 - 1/4
= 1763/180 </span>

Hey there!
The answer would be B. Geometric sequence with an initial value of 7 and a growth factor of 2. The first, or initial value is 7 in the sequence and each number is multiplied by 2 as the sequence goes on.
Hope this helps !
Answer:
400
$1 = 100p
$1 x 4 = 100 x 4
= 400p
Would love a brainliest - just need one more to get to the next level!
