Answer:
Yes
Explanation:
A nonlinear optimization problem is indeed a optimization problem in which there are nonlinear elements involved either as the objective function or one or more constraints may be nonlinear also. Let me show you an example. Let optimize de following function:

These are the constraints:

The last constraint consists on nonlinear elements, so this problem in fact a nonlinear optimization problem.
Explanation:
Using Ohm's Law and a bit of substitution, we can solve for current.
Answer:
An operating system, or "OS," is software that communicates with the hardware and allows other programs to run
Answer:
Explanation:
The following code is written in python and divides the amount of cents enterred in as an input into the correct amount of quarters, dimes, nickels and pennies. Finally, printing out all the values.
import math
#First we need to define the value of each coin
penny = 1
nickel = 5
dime = 10
quarter = 25
#Here we define the variables to hold the max number of each coin
quarters = 0
dimes = 0
nickels = 0
pennys = 0
cents = int(input("Please enter an amount of money you have in cents: "))
if cents > 0 and cents <= 100:
if cents >= 25:
quarters = cents / quarter
cents = cents % quarter
if cents >= 10:
dimes = cents/dime
cents = cents % dime
if cents >= 5:
nickels = cents /nickel
cents = cents % nickel
if cents > 0:
pennys = cents / penny
cents = 0
print("The coins are: "
"\nQuarters", math.floor(quarters),
"\nDimes", math.floor(dimes), "\nNickels", math.floor(nickels), "\nPennies", math.floor(pennys))
else:
print("wrong value")
