6.8. verify that u(x; y)=asin(2px) sin(2py) solves poisson’s equation ñ2u= onw = (0; 1)(0; 1) for some a-value, where r(x; y) = sin(2px) sin(2py). (a) find the correct a value. (b) compute the total source s = rr w rda: (c) compute the flux out through the top part of w (y = 1) and verify by symmetry that it is one-quarter that of the full source s.

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

two data sets with the same median will not have the same varaibility

step-by-step explanation:

207/8 is the right
