Answer:

When Scheme is a pure functional language, it cannot include the function DISPLAY. Since the pure functional languages will return the same value whenever the same expression is evaluated, and the DISPLAY would be the output and thus it cannot be part of the purely functional language. Thus in the pure functional language we can evaluate the expressions with the same arguments and it returns the same value since there is no state to change.

When determining the amount of RAM necessary for a computer you wish to purchase, what should you consider?

Igoryamba

Answer:

"The type of the software which a user wants to use" is a consideration point for the amount of ram while purchasing the computer system.

Explanation:

The Ram is primary memory, which is used when the system is in on mode. When there is less amount of Ram, then the user of the computers can not able to run multiple programs or runs that type of program which consumes more memory.
And if there is a high amount of RAM memory, then the user can run multiple programs at the same time or can run that program which takes more memory.
So when any user wants to decide about the Ram, then he can by deciding the type of software, which he wants to use. How much that software can use the memory.

simplify the expression below and state the value of m for which the simplified expression is not defined 2m² + m - 15/ m² - 9

motikmotik

Answer:

The simplified expression is: $\frac{2m-5}{m-3}$

The simplified expression is undefined for m=3

Explanation:

The given expression is:

$\frac{2m^2+m-15}{m^2-9}$

The numerator can be siplified by using factorization and denominator will be simplified using the formula

$a^2-b^2 = (a+b)(a-b)$

So,

$= \frac{2m^2+6m-5m-15}{(m)^2-(3)^2}\\=\frac{2m(m+3)-5(m+3)}{(m-3)(m+3)}\\=\frac{(2m-5)(m+3)}{(m-3)(m+3)}\\=\frac{2m-5}{m-3}$

A fraction is undefined when the denominator is zero. In order to find the value of m on which the simplified fraction will be undefined we will put denominator equal to zero.

So,

$m-3 = 0 => m = 3$

Hence,

The simplified expression is: $\frac{2m-5}{m-3}$

The simplified expression is undefined for m=3

Can some one fix this <br> input ("Enter a number: ") <br> print (num * 8)

Kaylis [27]

If you save the input as num,
this will print the input 8 times.

num = input("Enter a number: ")
print(num * 8)

If you want to do actual math calculations,
then the input needs to be a number.

num = float(input("Enter a number: "))
print(num * 8)

This doesn't account for any errors in which the user doesn't input a number, but I don't think that's what you were looking for anyway :)
