What do you mean by Square roots?
The square root of a number is an element that can replicate itself to find that number. The square root symbol is \ sqrt {} square root of, end square root. Finding the square root of a number is the opposite of multiplying a number.
Is √ it a square number?The square root of a number is a number that, when multiplied by itself, is equal to the required value. So, for example, the square root of 49 is 7 (7x7 = 49). The process of multiplying a number itself is called squaring.

Answer:
slope = - 4
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = - 1, 22) and (x₂, y₂ ) = (1, 14) ← 2 ordered pairs from the table
m = [tex]\frac{14-22}{1-(-1)}[/tex] = [tex]\frac{-8}{2}[/tex] = - 4

The point-slope form of the equation of the line that passes through (-9, -2) and (1, 3) is y– 3 = {(x - 1). What is the
slope-intercept form of the equation for this line?
Answer:
[tex]y=\dfrac{1}{2}x+\dfrac{5}{2}[/tex].
Step-by-step explanation:
If a line passing through two points, then the equation of line is
[tex](y-y_1)=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
It is given that the passing through (1,3) and (-9,-2). So, equation of line in point slope form is
[tex]\Rightarrow (y-3)=\dfrac{-2-3}{-9-1}(x-1)[/tex]
[tex]\Rightarrow (y-3)=\dfrac{1}{2}(x-1)[/tex]
Slope intercept form of a line is
[tex]y=mx+b[/tex]
where, m is slope and b is y-intercept.
Now,
[tex](y-3)=\dfrac{1}{2}(x-1)[/tex]
[tex]\Rightarrow (y-3)=\dfrac{1}{2}(x}-\dfrac{1}{2}(1)[/tex]
[tex]\Rightarrow y=\dfrac{1}{2}(x}-\dfrac{1}{2}+3[/tex]
[tex]\Rightarrow y=\dfrac{1}{2}x+\dfrac{5}{2}[/tex]
Therefore, the required equation is [tex]y=\dfrac{1}{2}x+\dfrac{5}{2}[/tex].

A jar of quarters and dimes contains $20.00. There are 110 coins in all. How many of each are there?
Answer:
There are 50 dimes and 110-50 = 60 quarters in the collection.
Step-by-step explanation:
Let D be the number of dimes.
Then the number of quarters is (110-D).
The "value equation" is
10D + 25*(110-D) = 2000.
Simplify and solve for D:
10D + 2750 - 25D = 2000,
-15D = 2000 - 2750,
-15D = -750,
D = %28-750%29%2F%28-15%29 = 50.

i really need an answer fast
x=-7
We can write them both like functions like this
A= 5x -4
B= 3x +8
Where
x=input
A=Output A
B=Output B
We want the output of A 3 times the output of B this can be written like this:
A= 3b
we replace with the functions
5x-4 = 3(3x+8)
solve for x and you get -7
f(x)=x^2
g(x) = (x– 9)^2 +3
We can think of g as a translated (shifted) version of f.
Answer:
To get the function g, shift f up by 3 units and to the right by 9 units.
Step-by-step explanation:
The given functions are
[tex]f(x)=x^2[/tex]
[tex]g(x)=(x-9)^2+3[/tex]
If f(x) is a parent function, then g(x) can be written in the form of f(x) as
[tex]g(x)=f(x-9)+3[/tex] ...(1)
The translation is defined as
[tex]g(x)=f(x+a)2+b[/tex] ... (2)
Where, a is horizontal shift and b is vertical shift.
If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
On comparing (1) and (2), we get
[tex]a=-9,b=3[/tex]
It means, to get the function g, shift f up by 3 units and to the right by 9 units.
Answer:
To get the function g, shift f up by 3 units and to the right by 9 units.
Step-by-step explanation:
F(x) = x^2, g(x) = 2/3 x^2 comparison
Answer:
g(x) is a vertical compression of f(x)
Step-by-step explanation:
Equation of graph 1 :[tex]f(x)=x^2[/tex]
Equation of graph 2 :[tex]g(x)=\frac{2}{3}x^2[/tex]
f(x)→a f(x)
Its is case of vertical stretch or compression
Vertical stretch if |a|>1
Vertical compression if 0<|a|<1
f(x)→a f(x)
So, [tex]x^2[/tex] →[tex]\frac{2}{3}x^2[/tex]
So, [tex]a= \frac{2}{3}=0.67[/tex]
So,0<|a|<1
So,It is a case of vertical compression
So, g(x) is a vertical compression of f(x)

which number would have to be added to "complete the square"?
Answer:

Find the value of y.
Answer:
Step-by-step explanation:
DB=√(y²-25)
again DB=√(x²-36)
so √(y²-25)=√(x²-36)
squaring
y²-25=x²-36
x²=y²-25+36
or x²=y²+11
also x²+y²=(6+5)²
x²+y²=121
y²+11+y²=121
2y²=121-11
2y²=110
y²=110/2=55
y=√55

A rectangle has a length 2x+1 and width x+3.
Write an expression that shows the area of
the rectangle. Be sure to simplify your
ansver.
Answer:
3x + 3
Step-by-step explanation:
to find the area we do length times width so to find the area of this rectangle we do 2x + 1 * x + 3
for this equation we have an order of operations problem we have to multiply 1 * x first so the answer becomes 3x + 3 because after the order of operstions the equation becomes 2x + 1x + 3
we then combine like terms / the x's
2x + 1x = 3x
then add 3
3x + 3

Ms. Wolfram's compost bin used for her garden is shaped like a rectangular prism. The bin is 4 inches long, 18 inches wide, and 9 inches tall. Ms. Wolfram has to fill 20% of the bin with brown material, like leaves, and 30% of the bin with green material, like vegetable scraps. What are the volumes of greens and
browns Ms. Wolfram needs to put in the bin? Please state how you got your answer
Green Material:
Brown material:
Ms. Wolfram should ask her husband Stephen, who's an incredible mathematician and computer scientist who's given the world a great gift in the website Wolfram Alpha which can answer all your math questions and more.
Anyway the volume of the bin is length times width times height,
V = 4 × 18 × 9 = 648 cubic inches
So the volume of brown is 20 % of that
B = 20% of V = .2 × 648 = 129.6 cubic inches
The volume of green is 30%,
G = 30% of V = .3 × 648 = 194.4 cubic inches
Answer: Green 194.4 cubic inches, Brown 129.6 cubic inches

Please answer the question stated below
Answer:
$252
Step-by-step explanation:
We need to find 30 percent of 400 dollars. Thirty percent can be written as 30/100, or 0.3.
Multiply 400 by 0.3, and we get $120. Since $120 is 30% of 400, we subtract 400 by 120. This gives us $280.
$280 is now the sale price. We need to find 10% of 280. Multiply 280 by 0.1, which gives us $28. This amount is taken off of the sale price, so we need to subtract 28 from 280.
280-28 is $252. This is the final price she will pay.

Step-by-step explanation:
Lets right the table in more clearer view.
x f(x)
0 5
4 2
6 9
9 10
The relation in coordinates form is written as (x, y) , x being the first term and y being the second term.
For x = 0, y = 5, so it can be written as (0,5)
Similarly, we can write the next values as:
(4,2)
(6,9)
(9,10)
So the data in the table is:
(0,5), (4,2), (6,9), (9,10)
It can be written is a set form
{(0,5), (4,2), (6,9), (9,10)}
Which is the same as option 1.
Hence, Option 1 is correct.
