The equation of the quadratic function y = x² + 6x + 3 in vertex form is y = (x+ 3)² - 6
Quadratic function in math is defined as a polynomial function with one or more variables in which the highest exponent of the variable is two.
Here we have given the quadratic function y = x² + 6x + 3 and we need to find the vertex form of the given quadratic function.
As we all know that the vertex form of the equation is given by
=> f(x) = a(x - h)² + k
Here we have given the expression that can be written as,
=> y = x² + 6x + 3
Now, we have to convert it into vertex form, then we get,
=> x² + 6x + 3
Expand the expression as follows:
=> x² + 6x + 3 + 9 - 9
Now, we have rewritten the expression like the following,
=> y + 9 = (x + 3)² + 3
Here we have to subtract 9 on both sides, then we get
=> y = (x+ 3)² + 3 - 9
Then the resulting equation is written as,
=> y = (x+ 3)² - 6

Temasa has a 1:10 scale drawing of her doll house in the drawing the dimensions of the rectangular house are 7 1/5 inches by 4 4/5 inches.The actual length is 72
inches
12 inches equals 1 feet, what is the area of Temasa's doll house
to the nearest SQUARE FOOT?
The area of the Temasa's doll house is 31.5 square feet.
What is the scale factor?
The scale factor is a ratio that compares the measurements of an object on a drawing or map to the actual measurements of that same object in real life. It is usually expressed as a ratio in the format 1:n (or 1/n) where n is the scale factor.
We can start by using the scale factor of 1:10 to find the actual dimensions of the doll house.
Since the scale factor is 1:10, this means that for every 1 inch on the drawing, the actual measurement is 10 inches. So, to find the actual length and width of the doll house, we can multiply the measurements on the drawing by 10.
7 1/5 inches * 10 = 71 inches + 2 inches
4 4/5 inches * 10 = 44 inches + 8 inches
So, the actual length of the doll house is 71 inches + 2 inches = 73 inches, and the actual width is 44 inches + 8 inches = 52 inches.
To find the area of the doll house, we can multiply the length and width:
73 inches * 52 inches = 3788 square inches
To convert this to square feet, we can divide by 12^2, since 1 foot = 12 inches:
3788 square inches / (12 inches)^2 = 31.5 square feet (rounded to the nearest square foot)
Hence, the area of the Temasa's doll house is 31.5 square feet.

g(x) = 2x + 4, h(x) = x² +1
Find g(h(24))
Using Composition of functions, the value of g(h(24)) = 1158.
What is meant by Composition of functions?A function is composed in mathematics when two functions, f and g, are used to create a new function, h, such that h(x) = g(f(x)). The function of g is being applied to the function of x, in this case. Therefore, a function is essentially applied to the output of another function.
The new function h is created by combining the two functions f and g, where h(x) = f(g(x)) for all x in g's domain where g(x) is in f's domain. Function composition is denoted by the notation h = f • g, also written as h(x) = (f • g)(x), which can be interpreted as "f of g of x."
Given,
g(x) = 2x + 4, h(x) = x² +1
Using composition of functions,
⇒ h(24) = 24² + 1
⇒ g(h(24)) = 2 (24² + 1) + 4
⇒ g(h(24)) = 2 × 577 + 4
⇒ g(h(24)) = 1158

There are three angles in a triangle ABC. A triangle is a three-sided polygon and it has three angles. Each angle is formed by the intersection of two sides of the triangle.
In a triangle, the angle between two sides is measured in degrees and these angles are formed by the intersection of the two lines that represent the sides of the triangle. The three angles in a triangle are labeled with the corresponding vertex, for example, angle A, angle B, and angle C.
In a triangle, the sum of the three angles is always 180 degrees. This can be proved using the fact that a straight line is 180 degrees. If we draw a straight line, and divide it into two angles, which are supplementary angles. Therefore, these angles add up to 180 degrees. In a triangle, we can draw one straight line and divide it into three angles, which are supplementary angles, therefore the sum of the angles in a triangle is always 180 degrees.
Therefore, In short, a triangle is a three-sided polygon with three angles, each angle is formed by the intersection of two sides of the triangle and these angles are labeled with the corresponding vertex. The sum of the three angles in a triangle is always 180 degrees.

Can a 2-digit number start with 0?.
No, a 2-digit number cannot start from Zero (0), as it can only have values ranging from 1 to 9.
When a number has two digits, it is called a 2-digit number. 2-digit numbers have two digits and range from 10 to 99. They are unable to begin with zero since it will then be regarded as a single-digit number. Any number between 1 and 9 can be used as the digit in the tens place.
The placement of each digit in a number is known as place value. There is just one place value that matters when discussing 1-digit numbers, and that is the ones place. There are two place values for 2-digit numbers: ones and tens. Two-digit numbers can be expressed verbally, numerically, or in their expanded form. 45 is a 2-digit number, for instance.

If so, what would be the donation for a dinner bill of $50? If not, explain. Donations Dinner Bill ($) 25 30 35 40 Donation ($ 4.50 5.40 6.30 7.20
Answer: Yes, $9.
Step-by-step explanation:
From what I understand, since the table isn't showing: \
Dinner bill $25:$4.50 tip, $30:$5.40, etc..
To find if Bill is proportional, we need to find the rate of each tip to Bill and see if they match.
$25/$4.50 =5.555555555...
$30/$5.40 =5.555555555...
$35/$6.30 =5.555555555...
$40/$7.20 =5.555555555...
The rate is the same for each one, so yes, the amount of the donation proportional to the dinner bill.
To find the donation for a bill of $50, divide by the rate we found above.

on its sides such that AE = BF=CG= DH as shown. The proof then
relies on quadrilateral EFGH being a square.
(a) First, explain why EFGH must be a rhombus. Use a paragraph proof
style, but carefully justify all of your statements with reasons.
(b) Give an explanation for why all interior angles of EFGH must be right angles? Explain why this fact in
combination with your proof in part (a) show that EFGH is a square?
We showed that EFGH is a square by proving that EFGH is a rhombus and all the angles are right angles. This is one of the classic proofs of the Pythagorean theorem.
How do you solve equations?(a) First, explain why the EFGH must be a rhombus.
In the figure, square ABCD has points E, F, G, and H on each side, so AE = BF = CG = DH, as shown. This means that all four sides of the rectangle EFGH are the same length. This is because they are all congruent with the side lengths of square ABCD. According to the definition of a rhombus, a rhombus is a quadrilateral with all four sides congruent. All four sides of the quadrilateral EFGH are congruent, so it must be a rhombus.
(b) Explain why all interior angles in EFGH must be right angles?
In square ABCD, by definition, all interior angles are right angles (90 degrees). Since the points E, F, G, and H lie on the sides of the square ABCD, the angles EFG and FGH are congruent to the right angle of the square ABCD. Similarly, the angles FGH and HGE are congruent to the right angle of the square ABCD.
Therefore, all four interior angles of quadrilateral EFGH are congruent with right angles of square ABCD, and all four interior angles of quadrilateral EFGH are right angles.
A square is a quadrilateral with all four sides congruent and all four angles congruent at right angles. And since it has already been proved that the quadrilateral EFGH is a rhombus and all its angles are right angles, we know that the quadrilateral EFGH is a square.
We showed that EFGH is a square by proving that EFGH is a rhombus and all the angles are right angles. This is one of the classic proofs of the Pythagorean theorem.

The equation of the line of best fit is: y = -1.15x + 102.8 and Using the equation of the line of best fit, the predicted cost is: $62.55
What is the Equation of a Line of Best Fit?
The equation of a line of best fit is represented by the equation, y = mx + b, where m is the slope and b is the initial value.
1. Using two points, (72, 20) and (20, 80):
Slope (m) = change in y / change in x = (80 - 20)/(20 - 72) = 60/-52
Slope (m) = -1.15.
Substitute m = -3 and (a, b) = (72, 20) into y - b = m(x - a)
y - 20 = -1.15(x - 72)
y - 20 = -1.15x + 82.8
y = -1.15x + 82.8 + 20
y = -1.15x + 102.8
The equation of the best line of fit is y = -1.15x + 102.8.
2. Monthly heating cost, y, for a month with an average temperature of 35°F (x) will be calculated by substituting x = 35 into y = -1.15x + 102.8.
y = -1.15(35) + 102.8
y = 62.55

Step-by-step explanation:
1. Before anything, figure out the inequality symbol. Why? In the solutions, all of the inequalities are different so you narrow it down by figuring out the inequality sign.
2. "At most 50 pounds" means we can't go over 50 pounds, but the package can still equal 50, that's just the most it can be. This means we will have a line underneath because it includes the maximum number, 50, in the solution.
3. "At most" also means the package (x) cannot be over 50. The sign opening must face 50 because that shows x has to be less than. But it can equal 50, so the sign is [tex]x\leq 50[/tex]. That would be B.
4. About the numbers, the box weighs 2 pounds. This means it is x+2 because weight is not negative and it is ADDING weight to what we don't know. To isolate x, just do 50-2, and you get 48. That again proves b is the answer.

What is the factor of a polynomial x² +6x 8 )?.
The factors of a polynomial x² +6x + 8 ( binomial, power of variable x is 2) are equals to the ( x + 2) ( x + 2).
In Mathematics, Factorisation of an algebraic expression is a process of writing the given expression as a product of its factors. These factors can be any type like numbers, variables, or an algebraic expression. To make the factor of a number means to break it up or decompose into numbers such that the multiplication of these can be get the original number. For example, In case of x² – 9 is (x – 3) (x + 3). In other words
(x- 3) and (x + 3) are the factors of x² – 9. We have, a polynomial say, p(x) = x² +6x + 8 and we have to factorize it. Now, x² +6x + 8 ----(*)
Split the middel term of above expression such that sum/difference of split terms is equal to 6x and multiplication of these give 8x².
=> x² + 4x + 2x + 8
group the pairs, => (x² + 2x ) + (4x + 8)
factor each group of pairs,
=> x( x + 2) + 2( x + 2)
Factor out the common term (x + 2)
=> (x + 2) ( x + 2)
Hence, required factors are ( x + 2) (x + 2).

Find triangle perimeter Please help quick, answer will be not useful after 4 hours
The perimeter of the triangle is given by the equation P = 4√3 feet
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the perimeter of the triangle be P
Let the triangle be represented as LMX
Now , An equilateral triangle is a triangle in which all three sides have the same length.
∠L = ∠M = ∠X = 60° and LM = MX = LX
The height of the triangle is LW = 2 feet
Now , from the trigonometric relations ,
sin 60° = opposite side / hypotenuse
Substituting the values in the equation , we get
√3 / 2 = 2 / LX
Multiply by LX on both sides of the equation , we get
LX ( √3/2 ) = 2
Multiply by ( 2/√3 )on both sides of the equation , we get
LX = 4/√3
Now , the perimeter of the triangle = LX + LM + MX
Perimeter of the triangle P = 3 ( 4/√3 )
Perimeter of the triangle P = 4√3 feet
Hence , the perimeter is 4√3 feet

The population of North Dakota in 2012 i 0. 3 million people. North Dakota ha a yearly population growth of 0. 017 million people. The population of South Dakota in 2012 i 0. 9 million people. South Dakota ha a yearly population growth of 0. 013 million people. Enter the minimun number of year it will take the population of North Dakota to equal the population of South Dakota given the curren rate of growth. Round your anwwer to the nearet tenth of a year
150 years is time required to when the population of north Dakota is equals to the population of South Dakota .
let t is time in years after which the population of both city are equals
so the population of north dakota after t years is given by :
0.3 + 0.017 t ----(i)
Population of South dakota after t years is given by:
0.9 + 0.013 t ----(ii)
for the population to be equal to each other equation (i) must be equal to equation (ii)
so , 0.3 + 0.017 t = 0.9 + 0.013 t
=> 0. 004 t = 0.6
=> 0.6/0.004
=> 150
so 150 years is the time required to make population of both city equals.
