Answer:
(1, 4)
(2, 7)
(0, 1)
(-1, -2)
Explanation:
to find ordered pairs, we plug in different values for x.
(remember, and "ordered pair" is (x, y)--the first number turns into the second number when put through the function)
usually, it's easiest to plug in smaller numbers, so that it is less complicated to graph
so, here's a few x values:
x = 1
y = 3x + 1
y = 3(1) + 1
y = 3 + 1
y = 4
so, when x = 1, y = 4
we write this as: (1, 4)
x = 2
y = 3x + 1
y = 3(2) + 1
y = 6 + 1
y = 7
so, when x = 2, y = 7
we write this as: (2, 7)
x = 0
y = 3x + 1
y = 3(0) + 1
y = 0 + 1
y = 1
so, when x = 0, y = 1
we write this as: (0, 1)
x = -1
y = 3x + 1
y = 3(-1) + 1
y = -3 + 1
y = -2
so, when x = -1, y = -2
we write this as: (-1, -2)

Given a list of numbers, find the correct function to find the sum of the squares of only the positive elements.
sqsum1
sqsum2
sqsum3
sqsum4
sqsum5
Answer:
sqsum4
Explanation:
So to raise a number to a power in python, you can use the ** operation, which is usually confused with the ^, which is an operation, but it is not for raising numbers to a power. It is the xor bit operation, which if you don't know at the moment, it's fine, since it's not necessary for this. each of these lists uses a generation comprehension which is generally defined as: (x for x in object if condition) with the if condition being optional, but in this case it's necessary. If it's a bit confusing, you can define a generator using a function so it's a bit more spread out:
def generator(object):
for x in object:
if condition:
yield x
Although in this instance were going to be performing some operation on x, which in this case is squaring it. So let's just look at the two functions that use the **, since they should be the only options that will be correct.
sqsum1(nums):
This function does square x, except it uses incorrect syntax. The condition should come after the for loop. Python likely wont tell you this, because it may think you're trying to do something else. You can do one line if statements like this: a if condition else b, which will return a if the condition is true, and b if it isn't. So it may think that you're trying to do this one line if statement, and say that you're missing an else. The function could even implement in this way: x**2 if x > 0 else 0 for x in nums. This way if the x is negative it counts as 0, or in other words isn't counted towards the sum. But without this fix, the function will raise a syntax error
sqsum4(nums):
This will square each number in x only if the current element "x" is greater than 0, or in other words positive. And then it returns the sum. So this function returns the expected output

ALTER TABLE customer ADD CONSTRAINT customer_number_unique UNIQUE (customer_number);
Use the following sentence, for instance, to add a unique constraint to the customer table's fname and lname columns: Change the customer table to add a unique constraint (lname, fname);
What ALTER TABLE statement to add a UNIQUE constraint?When using an ALTER TABLE query in SQL Server, the following syntax is used to create a unique constraint: (Column 1, Column 2,…, Column n) ALTER TABLE name ADD CONSTRAINT constraint name UNIQUE; table name
Each value in a column is guaranteed to be unique by the UNIQUE constraint.A column or collection of columns' uniqueness is ensured by the UNIQUE and PRIMARY KEY requirements. A UNIQUE constraint comes with a PRIMARY KEY constraint by default.

ii) Explain how space and time overheads arise from use of paging, and how the
Translation Lookaside Buffer (TLB) mitigates the time overheads.
Answer:
A translation lookaside buffer (TLB) is a memory cache that is used to reduce the time taken to access a user memory location.[1] It is a part of the chip's memory-management unit (MMU). The TLB stores the recent translations of virtual memory to physical memory and can be called an address-translation cache. A TLB may reside between the CPU and the CPU cache, between CPU cache and the main memory or between the different levels of the multi-level cache. The majority of desktop, laptop, and server processors include one or more TLBS in the memory-management hardware, and it is nearly always present in any processor that utilizes paged or segmented virtual memory.
Space and time overheads arise from use of paging, and how the Translation Lookaside Buffer (TLB) mitigates the time overheads contains the most recent jvm to memory address translations.
