The rate of flow outward through the hemisphere x² + y² + z² = 9, z >= 0 is zero.
Given that,
Seawater has a density of 1025 kg/m³ and moves at a constant velocity field defined by the equations v = yi + xj, where x, y, and z are measured in meters and the components of V are expressed in meters per second.
We have to find the rate of flow outward through the hemisphere x² + y² + z² = 9, z >= 0.
We know that,
v= yi + xj, and density = 1025 kg/m³
F=1025(yi + xj)
After solving the R(u,v) we get zero.
Therefore, the rate of flow outward through the hemisphere x² + y² + z² = 9, z >= 0 is zero.

The answer is
-1 ≤ x < 3
We just learned this is in my algebra 2 AP class
Neha ratio is 4:5
Daniel's ratio is 7:9
So, Daniel has the greater ratio.
Answer:
c) 4
The value of z= 4
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given equations are
3x - y =16 .. . (i)
3x -4z =2 .. . (ii)
2x +y = 14 .. .(iii)
solving (i) and (ii) equations , we get
Adding (i) and (ii)
3 x -y + 2x +y = 16 +14
5 x = 30
x = 6
<u><em>step(ii):-</em></u>
Substitute 'x' =6 in equation (i), we get
3(6) -y =16
18 - 16 =y
y = 2
x =6 and y =2
substitute x=6 in equation (ii) , we get
3 (6) - 4 z = 2
18 - 2 = 4 z
16 = 4 z
z = 4
<u><em>Final answer:-</em></u>
x = 6 , y = 2 and z =4
