Answer:
hundredths; 81.73
Step-by-step explanation:
If the number underlined is two, then it will rounding to the hundredths place. Since the number after it is 7, which is greater than 5, we get 81.73.
Answer:
Equation 1, Multiplied by 2: 2x + 4y = 10
Equation 1, Multiplied by 2: 2x + 4y - 10 = 10 - 10
Equation 1, Multiplied by 2: 2x + 4y - 10 = 0
Equation 1, Multiplied by 2: 2x - 2x + 4y - 10 = 0 - 2x
Equation 1, Multiplied by 2: 4y - 10 = - 2x
Equation 1, Multiplied by 2: - 10 + 4y = - 2x
Notice that Equation 1 = Equation 2
One Solution
Equation 1: x - y = -10
Equation 2: 2x + 3y = 15
Answer:
x = 4
Step-by-step explanation:
a = i-2j
b = 2i-xj
1 = k•2
-2 = k•(-x)
=> 1/2 = k
=> (-2)/(-x) = k
=> 1/2 = (-2)/(-x) => 1/2 = 2/x => x = 4
Answer:
The net outward flux across the boundary of the tetrahedron is: -4
Step-by-step explanation:
Given vector field F = ( -2x, y, - 2 z )
= -2 + 1 -2
= -3
According to divergence theorem;
Flux = 
x+y+z = 2; 
Octant
x from 0 to 2
y from 0 to 2 -x
z from 0 to 2-x-y
![= -3 \int\limits^2_0[(2-x)y - \dfrac{y^2}{2}]^{2-x}__0 \ \ dx](https://tex.z-dn.net/?f=%3D%20-3%20%5Cint%5Climits%5E2_0%5B%282-x%29y%20-%20%5Cdfrac%7By%5E2%7D%7B2%7D%5D%5E%7B2-x%7D__0%20%5C%20%5C%20dx)
= -4
Thus; The net outward flux across the boundary of the tetrahedron is: -4
A straight 'angle' is 180 degrees.
That's π radians.
