The function in the table is quadratic:
x f(x)
-1 1/3
0 1
1 3
2 9
The quadratic function that fits the given points is: f(x) = (4/3)x² - (10/3)x + 1
By using the simplification formula
f(x) = ax² + bx + c
where a, b, and c are constants
a(-1)² + b(-1) + c = 1/3
a(0)² + b(0) + c = 1
a(1)² + b(1) + c = 3
a(2)² + b(2) + c = 9
Simplifying each
a - b + c = 1/3
c = 1
a + b + c = 3
4a + 2b + c = 9
We can solve this using any method like substitution, elimination
a - b + c = 1/3
a + b + c = 3
2a + 2c = 9/3
Adding the first two equations 2a + 2c = 10/3
Subtracting the third equation
b = 5a/3 - 2
a - (5a/3 - 2) + 1 = 1/3
a = 4/3
Finally, we can substitute a = 4/3 and b = 5a/3 - 2, and c = 1 into the standard form of the quadratic equation to get: f(x) = (4/3)x² - (10/3)x + 1.

how create the own congruent postulate sss
Step-by-step explanation:
The SSS (Side-Side-Side) Congruence Postulate states that if three sides of a triangle are congruent to three sides of another triangle, then the triangles are congruent.
To create your own SSS Congruence Postulate, you could use the following statement:
"If the corresponding sides of two triangles are congruent, then the triangles are congruent."
This postulate would encompass the SSS Postulate, as well as two other postulates: the SAS (Side-Angle-Side) Postulate and the ASA (Angle-Side-Angle) Postulate.
Using this postulate, you could show that two triangles are congruent if, for example, their corresponding sides are all 5cm long. This would mean that the triangles have the same shape and size, even if they are oriented differently.

Whish of the following are necessary when proving that the angles of a parallelogram are congruent
D. Angle Addition Postulate is necessary when proving that the angles of a parallelogram are congruent.
What is parallelogram?
A parallelogram is a quadrilateral with two pairs of parallel sides. The opposite sides of a parallelogram are equal in length, and the opposite angles are equal in measure.
To prove that opposite angles of a parallelogram are congruent, we need to use the properties of parallelograms, such as opposite sides are parallel and congruent, opposite angles are congruent, consecutive angles are supplementary, and diagonals bisect each other.
We do not need the Segment Addition Postulate, as it is used to find a length of a segment, not to prove the congruence of angles.
We also do not need to use the Opposite sides are perpendicular property, as this is only true for a rectangle or a rhombus, but not necessarily for a parallelogram.
Similarly, the Angle Addition Postulate is used to find the measure of an angle, not to prove that angles are congruent.
Therefore, the only necessary property to prove that opposite angles of a parallelogram are congruent is that opposite angles are congruent, which is a property of parallelograms.

Step-by-step explanation:
Given:
Cylinder shaped cups
d (diameter) = 4,2 in
r (radius) = 0,5 × 4,2 = 2,1 in
h (height) = 7 in
π = 3.14
.
First, let's find how much juice can he pour into 1 cup:
.
We need to find the base of the cylinder:
.
[tex]a(base) = \pi {r}^{2} = 3.14 \times( {2.1})^{2} = 13.8474[/tex]
.
Now, we can find the volume of one cup:

The function g(x) is the height of a football x seconds after it is thrown in the air. The football reaches its maximum height of 28 feet in 6 seconds, and hits the ground at 12 seconds.
What is the practical domain for the function f(x)?
Type your answer in interval notation.
It can be expressed in interval notation as:[0, 12]
The practical domain for the function g(x) is [0,12], as this is the time during which the football is in the air, from the time it is thrown until it hits the ground.
The practical domain for the function g(x) would be the time interval during which the football is in the air, since it only makes sense to talk about the height of the football while it is airborne.
From the problem statement, we know that the football is thrown in the air at time x = 0, reaches its maximum height of 28 feet at time x = 6, and hits the ground at time x = 12. Therefore, the practical domain for the function g(x) is:
0 <= x <= 12
This means that the function g(x) is defined and meaningful for any value of x between 0 and 12, inclusive. Beyond this domain, the function does not have a practical interpretation because the football is either not yet thrown or has already hit the ground.
The function g(x) is the height of a football x seconds after it is thrown in the air. The football reaches its maximum height of 30 feet in 4 seconds, and hits the ground at 10 seconds.

Of(x) = 2x² - 4x-30
Of(x) = -x² + 2x + 15
Of(x)=x²-2x-15
Answer:
the answer is A) -2x² + 4x + 30
Step-by-step explanation:
To find the equation of the quadratic function f(x), we can use the standard form of a quadratic function: f(x) = ax^2 + bx + c, where a, b, and c are constants.
We can plug in the values of x and f(x) from the table to get three equations:
a(-1)^2 + b(-1) + c = 24
a(0)^2 + b(0) + c = 30
a(1)^2 + b(1) + c = 32
Simplifying each equation, we get:
a - b + c = 24
c = 30
a + b + c = 32
We can substitute c = 30 into the first and third equations to get:
a - b + 30 = 24
a + b + 30 = 32
Simplifying these equations, we get:
a - b = -6
a + b = 2
Adding these two equations, we get:
2a = -4
Dividing by 2, we get:
a = -2
Substituting a = -2 into one of the equations above, we get:
-2 - b = -6
Solving for b, we get:
b = 4
Therefore, the equation that represents f(x) is:
f(x) = -2x^2 + 4x + 30
So the answer is A) -2x² + 4x + 30

A company makes wax candles in the shape of a solid sphere. Suppose each candle has a diameter of 18 cm. If the company has a total of 152,604 cm³ of w
how many candles can be made?
Use 3.14 for x, and do not round your answer.
Answer:
50 spherical candles can be made with 152,604 cm³ of wax.
Step-by-step explanation:
Since the wax candles are in the shape of a solid sphere, we can calculate the volume of one candle by using the volume of a sphere formula.
[tex]\boxed{\begin{minipage}{4 cm}\underline{Volume of a sphere}\\\\$V=\dfrac{4}{3} \pi r^3$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius.\\\end{minipage}}[/tex]
The diameter of a sphere is twice its radius.
Therefore, if the diameter of the spherical candle is 18 cm, its radius is:
[tex]\implies r=\dfrac{d}{2}=\dfrac{18}{2}=9\; \sf cm[/tex]
Substitute r = 9 and π = 3.14 into the formula to calculate the volume of one spherical candle.
[tex]\begin{aligned}\implies \textsf{Volume of one candle}&=\sf \dfrac{4}{3} \cdot 3.14 \cdot (9\;cm)^3\\\\&=\sf \dfrac{4}{3} \cdot 3.14 \cdot 729\;cm^3\\\\&=\sf 3052.08\; \sf cm^3\end{aligned}[/tex]
Given the company has a total of 152,604 cm³ of wax, to calculate how many candles can be made, divide the total amount of available wax by the wax needed to make one candle.
[tex]\begin{aligned}\textsf{Total number of candles}&=\sf \dfrac{152604\; cm^3}{3052.08 \;cm^3}\\\\&=\sf 50\end{aligned}[/tex]
Therefore, 50 spherical candles can be made with 152,604 cm³ of wax.

A car was valued at $44,000 in the year 1992. The value depreciated to $15,000 by the year 2006.
A) What was the annual rate of change between 1992 and 2006?
r=---------------Round the rate of decrease to 4 decimal places.
B) What is the correct answer to part A written in percentage form?
r=---------------%
C) Assume that the car value continues to drop by the same percentage. What will the value be in the year 2009 ?
value = $ -----------------Round to the nearest 50 dollars.
(A) the annual rate of change between 1992 and 2006 was 0.0804
(B) r = 0.0804 * 100% = 8.04%
(C) value in 2009 = $11,650
What is the rate of change?
The rate of change is a mathematical concept that measures how much one quantity changes with respect to a change in another quantity. It is the ratio of the change in the output value of a function to the change in the input value of the function. It describes how fast or slow a variable is changing over time or distance.
A) The initial value is $44,000 and the final value is $15,000. The time elapsed is 2006 - 1992 = 14 years.
Using the formula for an annual rate of change (r):
final value = initial value * [tex](1 - r)^t[/tex]
where t is the number of years and r is the annual rate of change expressed as a decimal.
Substituting the given values, we get:
$15,000 = $44,000 * (1 - r)¹⁴
Solving for r, we get:
r = 0.0804
So, the annual rate of change between 1992 and 2006 was 0.0804 or approximately 0.0804.
B) To express the rate of change in percentage form, we need to multiply by 100 and add a percent sign:
r = 0.0804 * 100% = 8.04%
C) Assuming the car value continues to drop by the same percentage, we can use the same formula as before to find the value in the year 2009. The time elapsed from 2006 to 2009 is 3 years.
Substituting the known values, we get:
value in 2009 = $15,000 * (1 - 0.0804)³
value in 2009 = $11,628.40
Rounding to the nearest $50, we get:
value in 2009 = $11,650
Hence, (A) the annual rate of change between 1992 and 2006 was 0.0804
(B) r = 0.0804 * 100% = 8.04%
(C) value in 2009 = $11,650

Step-by-step explanation:

the figure can be considered as a combination of a 16×8 rectangle and a 10×8 right-angled triangle on the left side.
for both, perimeter and area, we need to find the length of the missing third side of the right-angled triangle, as this is a part of the long baseline of the overall figure.
as it is a right-angled triangle, we can use Pythagoras :
c² = a² + b²
"c" being the Hypotenuse (the side opposite of the 90° angle, in our case 10 ft). "a" and "b" being the legs (in our case 8 ft and unknown).
10² = 8² + (leg2)²
100 = 64 + (leg2)²
36 = (leg2)²
leg2 = 6 ft
that means the bottom baseline is 16 + 6 = 22 ft long.
a.
Perimeter = 10 + 16 + 8 + 22 = 56 ft
b.
Area is the sum of the area of the rectangle and the area of the triangle.
area rectangle = 16×8 = 128 ft²
area triangle (in a right-angled triangle the legs can be considered baseline and height) = 8×6/2 = 24 ft²
total Area = 128 + 24 = 152 ft²
7.
it was important that the bottom left angle of the quadrilateral was indicated as right angle (90°). otherwise this would not be solvable.
but so we know, it is actually a rectangle.
that means all corner angles are 90°.
therefore, the angle AMT = 90 - 20 = 70°.
the diagonals split these 90° angles into 2 parts that are equal in both corners of the diagonal, they are just up-down mirrored.
a.
so, the angle HTM = AMT = 70°.
b.
MEA is an isoceles triangle.
so, the angles AME and EAM are equal.
the angle AME = AMT = EAM = 70°.
the sum of all angles in a triangle is always 180°.
therefore,
the angle MEA = 180 - 70 - 70 = 40°
c.
both diagonals are equally long, and they intersect each other at their corresponding midpoints.
so, when AE = 15 cm, then AH = 2×15 = 30 cm.
TM = AH = 30 cm.
Write the following as an algebraic expression in u, u > 0. sin (artan u/ square root 3)
Answer: Let's start by using the identity:
tan(arctan(x)) = x
to simplify the expression inside the sine function. So, we have:
arctan(u) / sqrt(3) = tan(arctan(u) / sqrt(3))
Now, using the trigonometric identity:
tan(x/y) = sin(x) / (cos(y) + sin(y))
with x = arctan(u) and y = sqrt(3), we get:
tan(arctan(u) / sqrt(3)) = sin(arctan(u)) / (cos(sqrt(3)) + sin(sqrt(3)))
Simplifying further, we know that:
sin(arctan(u)) = u / sqrt(1 + u^2)
and
cos(sqrt(3)) + sin(sqrt(3)) = 2cos(sqrt(3) - pi/4)
So, the expression becomes:
sin(arctan(u) / sqrt(3)) = u / sqrt(1 + u^2) / [2cos(sqrt(3) - pi/4)]
Simplifying the denominator, we have:
sin(arctan(u) / sqrt(3)) = u / sqrt(1 + u^2) / (2(cos(sqrt(3))cos(pi/4) + sin(sqrt(3))sin(pi/4)))
Using the values for cosine and sine of pi/4, we get:
cos(pi/4) = sin(pi/4) = 1/sqrt(2)
So, we have:
sin(arctan(u) / sqrt(3)) = u / sqrt(1 + u^2) / [2(sqrt(3)/2 + 1/2)]
Simplifying further:
sin(arctan(u) / sqrt(3)) = u / (sqrt(1 + u^2) * (sqrt(3) + 1))
Therefore, the algebraic expression for sin(arctan(u) / sqrt(3)) is:
u / (sqrt(1 + u^2) * (sqrt(3) + 1))

What is the Surface Area of the Triangular Prism below?
Surface area is calculated as 48 + 120 = 168 square units (area of triangular faces + area of rectangular faces).
A triangular prism is what?A polyhedron with two triangular sides and three rectangles sides is referred to as a triangular prism. It is a three-dimensional shape with two base faces, three side faces, and connections between them at the edges.
Given :
We must calculate the area of each face of the triangular prism and put them together to determine its surface area.
The areas of the triangular faces are equal, so we may calculate one of their areas and multiply it by two:
One triangular face's area is equal to (1/2) the sum of its base and height, or (1/2) 6 x 8 x 6, or 24 square units.
Both triangular faces' surface area is 2 x 24 or 48 square units.
Finding the area of the rectangular faces is now necessary:
One rectangular face's area is given by length x breadth (10 x 6) = 60 square units.
120 square units are the area of both rectangular faces or 2 by 60.
Hence, the triangular prism's total surface area is:
Surface area is calculated as 48 + 120 = 168 square units (area of triangular faces + area of rectangular faces).
