the sum of two nonnegative numbers is 20
a. the sum of their squares is as large as possible; as small as possible
b. oen number plus the square root of th eother is as large as possible; as samll as possible
Homework Answers
then
S = x^2 + (20-x)^2
take dS/dx, set that equal to zero and solve
b) S = (20-x) + √x
same thing, find dS/dx, set equal to zero and solve

Write a TM (Turing Machine) program that adds two base two numbers. Input is two nonnegative integers in base 2 with a plus sign between them. Output is their sum in base 2, with nothing else left on the tape. So first decrement, then increment. Use an online Turing Machine Simulator to see how it works. Use the following language for the program: current state, read symbol, next state, write symbol, direction [directions are (< left, > right, s stay)]...

ANSWER USING JAVA CODE (1)The sum of the squares of the first ten natural numbers is, 12 + 22 + ... + 102 = 385 The square of the sum of the first ten natural numbers is, (1 + 2 + ... + 10)2 = 552 = 3025 Hence the difference between the sum of the squares of the first ten natural numbers and the square of the sum is 3025 − 385 = 2640. Find the difference between the...
