Answer 1

Answer #1

The product depends on the sign of the integer. For suppose assume two integer a and b, their magnitude is equal |a| = |b|.i.e, for example a = 10 then also b=10.

Now considering the sign of the two integers,

(+a) ×(+b) =ab,

(+a) ×(-b) = -ab,

(-a) ×(+b) = -ab,

(-a) ×(-b) = ab.

A positive integer is a prime number if its only positive integer divisors are itself and 1. Write a program to determine whether or not a given integer is prime. The program should contain two functions: main: to ask the user for a positive integer and to print the result isPrime: to determine whether the user's input is prime by testing all possible divisors. This function should return two values: variable_1: a Boolean value indicating whether the number is prime...

Q2. Suppose that you can sell as much of a product (in integer units) as you like at $60 per unit. Your marginal cost (MC) for producing the qth unit is given by: MC=7qMC=7q This means that each unit costs more to produce than the previous one (e.g., the first unit costs 7*1, the second unit (by itself) costs 7*2, etc.). If fixed costs are $100, what is the profit at the optimal integer output level? Please specify your answer...
