Answer:
399 minutes a month
Step-by-step explanation:
As I understand the question the answer would, in other words, be how many minutes you can long-distance call with the economy plan for under $30.
The unit ratio is 5 cents per minute, which equates to 20 minutes worth of call time for one dollar (100/5).
The economy plan is $20 cheaper than the deluxe plan. $20 spent on long-distance calling gets you 400 mintues, but the question asks for an integer that would still leave remaining money.
Therefore the answer is 399 minutes of long-distance calling, which would leave five unspent cents.
Both functions are the solution to the given Laplace solution.
Given Laplace's equation: 
- We must determine whether a given function is the solution to a given Laplace equation.
- If a function is a solution to a given Laplace's equation, it satisfies the solution.
(1) 
Differentiate with respect to x as follows:

Differentiate with respect to y as follows:

Supplement the values in the given Laplace equation.

The given function in this case is the solution to the given Laplace equation.
(2) 
Differentiate with respect to x as follows:

Differentiate with respect to y as follows:

Substitute the values to obtain:

The given function in this case is the solution to the given Laplace equation.
Therefore, both functions are the solution to the given Laplace solution.

The correct question is given below:
Determine whether each of the following functions is a solution of Laplace's equation uxx + uyy = 0. (Select all that apply.) u = e^(−x) cos(y) − e^(−y) cos(x) u = sin(x) cosh(y) + cos(x) sinh(y)
