<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>

Range = 9
Step-by-step explanation:
Answer:
The answer would be -1,-3.
She is paid every OTHER week.....so she is gonna get paid : 52/2 = 26 times
26(2633.65) = 68474.90
plus she gets a bonus of 10% of her yearly salary
68474.90 (1.10) = 75322.39 rounds to 75322 <===
Answer:
45.5
Step-by-step explanation:
Divide 26 by 4 and then you know how much jurgen can bike an hour, then multiply by 7
