Hey there!
Finding the the answer to the [Binomial]
(a + b)^2
CONVERT:
= (a + b)(a + b)
DISTRIBUTE
= a(a) + a(b) + b(a) + b(b)
= a^2 + ab + ab + b^2
COMBINE the LIKE TERMS
= (a^2) + (ab + ab) + (b^2)
= a^2 + ab + ab + b^2
= a^2 + 1ab + 1ab + b^2
= a^2 + 2ab + b^2
Therefore, your answer should be:
a^2 + 2ab + b^2
Good luck on your assignment & enjoy your day!

A probability sampling method in which we randomly select one of the first k elements and then select every kth element thereafter is _____ sampling.
A probability sampling method in which we randomly select one of the first k elements and then select every kth element thereafter is systematic sampling.
What is systematic sampling?Systematic sampling is a statistical method used in survey methodology that involves selecting elements from an ordered sampling frame. An equiprobability method is the most common type of systematic sampling. The list is traversed in a circular fashion in this approach, with a return to the top once the end of the list is reached. Systematic sampling is a probability sampling method in which we randomly select one of the first k elements and then select every kth element after that. Using this method, each element in the population has a known and equal chance of being selected (also known as Epsem). As a result, systematic sampling is functionally equivalent to simple random sampling (SRS).Therefore, a probability sampling method in which we randomly select one of the first k elements and then select every kth element thereafter is systematic sampling.

2|x|-9 translate 6 units up
The translation of the function 2 | x | - 9 when translated 6 units up gives the function as 2 | x | - 3.
We are given a function:
2 | x | - 9.
A function from a set X to a set Y assigns to each element of X exactly one element of Y.
We are asked to translate the function 6 units up.
This means that we have to add 6 units to the function.
A function has been “translated” when it has been moved in a way that does not change its shape or rotate it in any way.
So, we get that:
f(x) = 2 | x | - 9 + 6
f(x) = 2 | x | - 3
Therefore, the translation of the function 2 | x | - 9 when translated 6 units up gives the function as 2 | x | - 3.

Linda built a games board in industrial arts class. The top was a rectangle of 60cm by 48cm. What was the largest size of identical felt squares she could use to cover the top exactly?
The largest size of identical felt squares that can be used to cover the top of rectangle is 5 squares of side 24cm.
The rectangle is a 2-dimensional figure with length and breadth which may or may not be same. A square is also a 2-dimensional figure with equal length of its sides.
When the dimensions of rectangle are given, it's are is given as the product of the sides of the rectangle which is given as:
Area of rectangle = Length × Breadth = 60 × 48 = 2880 cm square
The length of the square that entirely covers up the top side i.e., rectangular top can be determined by hit and trial mechanism starting from the lowest whole number in order to determine the length of largest squares of equal dimensions. Then comparing the area of the rectangular top and product of number of squares needed and area of each square, we can find the largest size of the square.
Area of square = length × length = l²
Since, Area of rectangular top = No. of squares × Area of 1 square
Therefore, 2880 = N (l²)
Putting N =1, 2, 3, 4, 5 and so on, we find that when N = 5, the value of square root of l is a perfect whole number.
Hence, 2880 = 5 × (l²)
l = √576 = 24
Thus, 5 squares of side 24cm will be used to cover the rectangular top entirely.

the length of a retangle is 4 times its width. The rectangles width is 8 m. What is the are of the rectangle?
The rectangle's width is 8m and the length is 4 times the width, so the length = 4 x 8 = 32m
To calculate the area of a rectangle, we take the width and multiply it with the length
A = 32 x 8 = 256m2

robert spends 30.45$, before tax, at the store.
The cost of Robert purchase of books after the paid tax is $32.66.
What is defined as the percentage increase?The percentage increase would be the difference between both the final and initial values expressed as a percentage. For other sayings, it is the difference here between final and initial values divided by the original value and multiplied by 100.For the given question;
The original cost of the book purchased by the Robet = $30.45.
The tax of 7.25% is applied on the original cost of the book.
7.25% of $30.45 = (7.25×30.45)/100
7.25% of $30.45 = $2.21
The final cost of the book = original cost + tax
The final cost of the book = $30.45 + %2.21
The final cost of the book = 32.66
Therefore, the total price paid by the Robert for the book after 7.5% of the tax is applied is $36.66.

A scientist uses a submarine to study ocean life.
She begins 174 feet below sea level.
After traveling down for 15 seconds, she's 252 feet below sea level.
Find the rate of change in the submarine's elevation in feet per second. Round your answer to the nearest tenth.
The rate of change in the submarine's elevation in feet per second is 5.2
According to the question ,
She starts 174 feet below sea level
after 15 minutes she reaches 252 feet below sea level
distance travel in 15 minutes = [tex]\frac{252 - 174}{15}[/tex]
= [tex]\frac{78}{15}[/tex]
= [tex]\frac{26}{5}[/tex]
Round off [tex]\frac{26}{5}[/tex] = 5.2
There are certain rules to follow when rounding a decimal number. Put simply, if the last digit is less than 5, round the previous digit down. However, if it’s 5 or more than you should round the previous digit up. So, if the number you are about to round is followed by 5, 6, 7, 8, 9 round the number up. And if it is followed by 0, 1, 2, 3, 4 round the number down.
Here some Rounding Examples :
Consider the number 8.9163
8.9163 rounded to the nearest tenth is 8.9
Because 9 is followed by 1 and 1 is less than 5.
8.9163 rounded to the nearest hundredth is 8.92
Because 1 is followed by 6 and 6 is greater than 5.
8.9163 rounded to the nearest thousandth is 8.916
Because 6 is followed by 3 and 3 is less than 5.

factor?
It is scale factor at 1/14.
What does scale factor mean?The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller). For instance, by increasing each side by, say, 2, we can expand the size of a rectangle with sides of 2 cm and 4 cm.
The fundamental equation to determine a figure's scale factor is written as, Scale factor is equal to the difference between the dimensions of the new and old shapes.
