A perfect square is an expression that factors into two other expressions that are identical. The equation that represents this model is (2x)²=4x².
What is a perfect square monomial?
A perfect square is an expression that factors into two other expressions that are identical. A monomial is a single phrase made up of a product of constants, variables, and their positive integer powers. As a result, a perfect square monomial is a monomial that factors into two monomials that are identical.
As given to us that the first row consists of tile 2x², and the second row also consists of tile 2x². Thus, the expression can be written as,
[tex]2x^2+2x^2\\\\=(2x)^2=4x^2[/tex]
Hence, the equation that represents this model is (2x)²=4x².

explain how the unit circle definition of sin and cos is related to the equations sin(theta)=O/H and cos(theta)=A/H
The sine and cosine are related to the definitions because of the identity [tex]\cos^{2}\theta + \sin^{2}\theta = 1[/tex].
How cosine and sine are related in the unit circleThe unit circle is a particular case of the Pythagorean theorem, in which hypotenuse ([tex]r[/tex]) has a measure of a unit. That is:
[tex]x^{2}+y^{2} = r^{2}[/tex] (1)
Where:
[tex]x[/tex] - Horizontal leg[tex]y[/tex] - Vertical legIf we divide the entire expression by [tex]r^{2}[/tex], then we have the following identity:
[tex]\left(\frac{x}{r} \right)^{2}+\left(\frac{y}{r} \right)^{2} = 1[/tex]
And by trigonometric relations, we have the following formula:
[tex]\cos^{2}\theta + \sin^{2}\theta = 1[/tex] (2)
The sine and cosine are related to the definitions because of the identity [tex]\cos^{2}\theta + \sin^{2}\theta = 1[/tex]. [tex]\blacksquare[/tex]

Step-by-step explanation:
sum of angle of quadrilateral is 360°
so,
2a+3a+4a+6a=360°
15a=360°
a = 360°/15= 24°

Step-by-step explanation:
Bill is twice as old as Adam
Charlie is 3 years younger than Bill
The sum of their three ages is 27
Find the ratio of Adam's age to Charlie's age, giving your answer in the form 1:n
Answer:
[tex] \frac{1}{1.5} [/tex]
Step-by-step explanation:
Let B represent Bill age
A be adam age
C be charlie age
We know that
[tex]b = 2a[/tex]
We also know that
[tex]c = b - 3[/tex]
And we know that
[tex]a + b + c = 27[/tex]
Fist let subsitue c for b-3
[tex]a + b + (b - 3) = 27[/tex]
[tex]a + 2b - 3 = 27[/tex]
[tex]a + 2b = 30[/tex]
We know that b=2a so
[tex]a + 2(2a) = 30[/tex]
[tex]a + 4a = 30[/tex]
[tex]5a = 30[/tex]
[tex]a = 6[/tex]
Plug that in first equation to solve for b
[tex]b = 2(6)[/tex]
[tex]b = 12[/tex]
Finally plug that in the final equation to solve for c.
[tex]6 + 12 + c = 27[/tex]
[tex]c = 9[/tex]
Know we want the ratio of Adam age, a to Charlie age, c.
So we have
[tex] \frac{6}{9} = \frac{2}{3} = \frac{1}{1.5} [/tex]

Answer:
-2/5
Step-by-step explanation:
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).

how to find the missing side of a triangle in trig for geometry
Step-by-step explanation:
cosine is cos(angle)= adjacent/hypotenuse
sine is sin(angle) = opposite/hypotenuse
Tangent is tan(angle)= opposite/adjacent
for all of those
if the equation is something like tan(69)= x/69
multiply both sides by 69 so it will end up as x=69tan(69) and put that in the calculator
if it is something like tan(69)= 69/x
just swap x and tan(69)
it is much easier
it will then be 69/tan(69) and put that in the calculator

Two congruent squares and a parallelogram were used to form the figure shown.
3 m; 2.8 m; 6 m; 3 m.
What is the area of the figure in square meters?
25.8 m2
40.8 m2
34.8 m2
28.8 m2
Answer:
the answer is 40.8 m2
Step-by-step explanation:
The area of a figure is the amount of space the figure occupies
The surface area of the figure is 34.8 square meters
How to determine the area of the shape
From the question, we have:
The dimensions of the congruent squares are 3 m by 3 m
The dimensions of the parallelogram are height of 2.8 m, and base of 6 m
So, the area of the figure is:
Area = 2 * Area of square + Area of parallelogram
This gives
Evaluate the products
Evaluate the sum
Hence, the surface area of the figure is 34.8 square meters

so the answer is 40.8 m2
The area of a figure is the amount of space the figure occupies
Hence, The surface area of the figure is 34.8 square meters
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Now, From the question, we have:
The dimensions of the congruent squares are 3 m by 3 m
The dimensions of the parallelogram are height of 2.8 m, and base of 6 m
So, the area of the figure is:
Area = 2 × Area of square + Area of parallelogram
This gives;
Area = 2 × 3 × 3 + 2.8 × 6
Area = 18 + 16.8
Area = 34.8 m²
Hence, The surface area of the figure is. 34.8 square meters

a family buys 5 airline tickets online. The family buys travel insurance that costs $17 per ticket. The total cost is $1,495. Let x represent the price of one ticket. Write an equation for the total cost. Then find the price of one ticket.
Answer:
$282
Step-by-step explanation:
The price per ticket can be found by dividing the total cost by the number of tickets, then subtracting the value of any per-ticket add-ons.
5(x +17) = 1495 . . . . . total cost of 5 tickets with 17 per ticket ins charge
x +17 = 299 . . . . . . divide by 5
x = 282 . . . . . . . price of 1 ticket

On Nick's playlist, 5/12 of the songs are pop. What fraction of the
songs, n, are NOT pop?
How can you draw a picture and write an equation to
represent the problem?
Answer:
7/12
Step-by-step explanation:
Draw a rectangle with 12 squares. 5 of them will be pop and 7 will not.
The equation will be 12/12 = 5/12 + n. You will subtract 5/12 from each side and get 7/12 = n.

By solving a linear equation, we can see that you should use 4lb of the $2.4/lb mix.
How much of each mixture should you use?
First, if you use x pounds of the $2.4/lb mix, the total mass of mixture that you will have is:
(x + 5lb).
And that mass must cost $1.5/lb, so the costs on the left side must be equivalent to the cost on the right side.
x*$2.4/lb + 5lb*($1.5/lb) = (x + 5lb)$1.9/lb
Now we need to solve this for x
x*$2.4/lb + 5lb*($1.5/lb) = x*$1.9/lb + 5lb*$1.9/lb
x*$2.4/lb - x*$1.9/lb = 5lb*$1.9/lb - 5lb*($1.5/lb)
x*$0.5/lb = $2
x = $2/($0.5/lb) = 4lb
You should use 4lb of the $2.4/lb mix.

1. A bottling company uses a machine to fill the bottles with olive oil. These bottles are
designed to contain 475 millilitres (ml). In fact, the contents vary according to a normal
distribution with a mean of 473 ml and standard deviation of 3 ml. A) What is the distribution, mean, and standard error of the sample mean of six randomly
selected bottles?
Using the Central Limit Theorem, it is found that the distribution of the sample mean of six randomly selected bottles is approximately normal, with mean 473 ml and standard error of 1.22 ml.
Central Limit TheoremThe Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
In this problem, for the population, we have that:
[tex]\mu = 473, \sigma = 3[/tex]
Then, for the sample of n = 6:
[tex]s = \frac{3}{\sqrt{6}} = 1.22[/tex]
