Please answer quick
Answers
The balanced chemical equations, of the combustion reactions found by plugging in the right coefficients in front of the molecules according to the rules of conservation of atoms are;
1) 2C + 2O₂ ⇒ 2CO₂
2) CH₄ + 2O₂ ⇒ CO₂ + 2H₂O
3) 2C₄H₁₀ + 13O₂ ⇒ 8CO₂ + 10H₂O
What is a combustion reaction?A combustion reaction is one in which a combustible substance reacts with an oxidizer such as oxygen, to become oxidized.
1) 2C + ...O₂ ⇒ CO₂
The number of carbon atoms in the reaction side of the equation is 2, and the number of oxygen atoms in the reaction side are 2
In the product side of the equation, we get;
The number of carbon atoms = 1
The number of oxygen atoms = 2
The ratio of the number of oxygen atoms in the reaction side to the number of oxygen atoms in the product side = 1 : 1
The ratio of the number of carbon atoms in the reaction side to the number of oxygen carbon in the product side = 2 : 1
Multiplying the O₂ by 2 and the CO₂ by 2, we get;
2C + 2O₂ ⇒ 2CO₂2) CH₄ +... O₂ ⇒ CO₂ + ....H₂O
Reaction side;
Number of carbon atoms = 1
Number of hydrogen atoms = 4
Number of oxygen atoms = 2
Product side;
Number of carbon atoms = 1
Number of hydrogen atoms = 2
Number of oxygen atoms = 3
Set the coefficient of O₂ as 2, and the coefficient of H₂O as 2, we get;
CH₄ + 2O₂ ⇒ CO₂ + 2H₂OThe above equation is balanced
3) 2C₄H₁₀ + ...O₂ ⇒ ...CO₂ + ....H₂O
Reaction side;
Number of carbon atoms = 8
Number of hydrogen atoms = 20
Number of oxygen atoms = 2
Product side;
Number of carbon atoms = 1
Number of hydrogen atoms = 2
Number of oxygen atoms = 3
Multiply the O₂ by 13, the CO₂ by 8, and the H₂O by 10, we get the balanced equation as follows;

A circle is centered at O. The tangent to the circle at P is extended to Q. Line segment QS intersects the circle at R. Given that OS = 2, SR = RQ = 3, and PQ = 6, find the radius of the circle.
Answers
The radius of the circle will be [tex]\sqrt{22}[/tex].
In our question, we shall first extend QRS to the circle's point T.
According to the power of a point.
[tex]QP^{2}[/tex] = QR*QT
[tex]6^{2}[/tex] = 3*QT
QT = 12
Since QR = 3, RT = 9.
Since RS = 3, ST = 6.
Draw OT and OR, creating a triangle(TSO) and triangle(RSO).
OT and OR are radii, Let the radius be r.
Use the Law of Cosines on these two triangles.
OT2 = [tex]r^{2}[/tex] = [tex]6^{2}[/tex] + [tex]2^{2}[/tex] - 2*6*2*cos(TSO)
OR2 = r2 = [tex]3^{2}[/tex] + [tex]2^{2}[/tex] - 2*3*2*cos(RSO)
Since these are equal:
[tex]6^{2}[/tex] + [tex]2^{2}[/tex] - 2*6*2*cos(TSO) = [tex]3^{2}[/tex] + [tex]2^{2}[/tex] - 2*3*2*cos(RSO)
40 - 24*cos(TSO) = 13 - 12*cos(RSO)
Since angle(RSO) is supplementary to angle(TSO), cos(RSO) = - cos(TSO)
40 - 24*cos(TSO) = 13 + 12*cos(TSO)
27 = 36*cos(TSO)
0.75 = cos(TSO)
Since [tex]OT^{2}[/tex] = [tex]r^{2}[/tex] = [tex]6^{2}[/tex] + [tex]2^{2}[/tex] - 2*6*2*cos(TSO)
[tex]r^{2}[/tex] = 40 - 24*0.75
[tex]r^{2}[/tex] = 22
r = [tex]\sqrt{22}[/tex]
Hence the radius of the given circle will be [tex]\sqrt{22}[/tex].

Which inequality represents all the solutions of 10(3x + 2) > 7(2x − 4)?
Answers
Answer:
Step-by-step explanation:
The inequality that represents all the solutions of 10(3x + 2) > 7(2x − 4) is 10(3x + 2) > 7(2x − 4). To solve this inequality, first we must combine like terms on each side of the inequality. On the left side, 10(3x + 2) becomes 30x + 20. On the right side, 7(2x − 4) becomes 14x − 28. After combining the like terms, the inequality becomes 30x + 20 > 14x − 28. Next, we must subtract 14x from both sides of the inequality. On the left side, 30x + 20 becomes 16x + 20. On the right side, 14x − 28 becomes −28. After subtracting 14x from both sides, the inequality becomes 16x + 20 > −28. Finally, we must subtract 20 from both sides of the inequality. On the left side, 16x + 20 becomes 16x. On the right side, −28 becomes −48. After subtracting 20 from both sides, the inequality becomes 16x > −48. To solve the inequality, we must divide both sides of the inequality by 16. On the left side, 16x becomes x. On the right side, −48 becomes −3. Therefore, the solution to the inequality is x > −3.

Answers
The anti-derivative of g(x) is G(x) = x3 + 3x2 and the anti-derivative of f(x) is F(x) = x2 + 2x.
Part a:
The value of the integral from 0 to 6 of f(x)dx is 16. This can be calculated using the Fundamental Theorem of Calculus (FTC) which states that the integral of a function is equal to the anti-derivative of that function evaluated at the upper limit minus the anti-derivative of that function evaluated at the lower limit. This can be written as:
∫f(x)dx = F(6) - F(0)
The anti-derivative of f(x) is F(x) = x2 + 2x, so the value of the integral is:
∫f(x)dx = (62 + 2*6) - (02 + 2*0) = 36 - 0 = 16.
Part b:
The value of the integral from 4 to 9 of g(x)dx is 20. This can be calculated using the FTC which states that the integral of a function is equal to the anti-derivative of that function evaluated at the upper limit minus the anti-derivative of that function evaluated at the lower limit. This can be written as:
∫g(x)dx = G(9) - G(4)
The anti-derivative of g(x) is G(x) = x3 + 3x2, so the value of the integral is:
∫g(x)dx = (93 + 3*9) - (43 + 3*4) = 729 - 168 = 20.
Part c:
The value of the integral from 4 to 9 of 2*g(x) - f(x)dx is 68. This can be calculated using the FTC which states that the integral of a function is equal to the anti-derivative of that function evaluated at the upper limit minus the anti-derivative of that function evaluated at the lower limit. This can be written as:
∫(2*g(x) - f(x))dx = 2*G(9) - F(9) - [2*G(4) - F(4)]
The anti-derivative of g(x) is G(x) = x3 + 3x2 and the anti-derivative of f(x) is F(x) = x2 + 2x, so the value of the integral is:
∫(2*g(x) - f(x))dx = (2*(93 + 3*9) - (92 + 2*9)) - [2*(43 + 3*4) - (42 + 2*4)]
= (1854 - 19) - (544 - 16) = 1735 - 528 = 68.

How to define the sine function?The sine function for this problem is defined as follows:
y = Asin(B(x - C)) + D.
The parameters are described as follows:
A is the amplitude.The period is of 2π/B.C is the phase shift.D is the vertical shift.The function has a minimum value of -3 and a maximum value of 3, for a difference of 6, hence the amplitude is obtained as follows:
2A = 6
A = 3.
The function has no vertical shift, as it oscillates between -1 x 3 = -3 and 1 x 3 = 3.
The period is of 10 units, hence the coefficient B is given as follows:
2π/B = 10
10B = 2π
B = π/5.
Due to it's midline, the function was shifted 0.5 units left, hence the coefficient C is given as follows:

write an explicit rule for the sequence {-7,-1,5,11,17}. what is the position number for the term 47?
Answers
The position number for term 47 is 269.
This is an arithmetic sequence since each term has a common difference. Let us test it.
The difference between 1st and 2nd terms is
-7 + d = -1
d = -1 + 7
= 6
Now we check the difference for term
The difference between 3rd and 4th terms is
5 + d = 11
d = 11 – 5
= 6
So the difference is the same so we can apply a common equation for arithmetic sequence
[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + d ( n - 1 )
Where :
[tex]a_{n}[/tex] = number at term n
[tex]a_{1}[/tex] = first number of sequence
d = difference for each number sequence
n = term
From the question, we need to find the number at position term 47
[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + d ( n - 1 )
[tex]a_{47}[/tex] = -7 + 6 ( 47 - 1 )
= -7 + 6 ( 46 )
= -7 + 276

Answers
The ratio of water, sucrose, and saline solution needed is 1000:199:271 in its simplest form.
The amount of water, sucrose, and the saline solution used can be expressed as a ratio in its simplest form by finding the greatest common divisor (GCD) of the three quantities and dividing each by it.
1l of water = 1000 ml of water.
Let's find the GCD of the three quantities:
GCD(199,271,1000) = 1
So we can express the amount of water, sucrose, and saline solution needed as a ratio in its simplest form by dividing each of the three quantities by 1
Water : Sucrose : Saline solution = 1000 : 199/1 : 271/1 = 1000:199:271

The surface area of a box with a height of 8 inches, a length of 12 inches, and a width of 6 inches can be calculated using the formula SA = 2lw + 2lh + 2wh. In this case, SA stands for surface area, l stands for length, w stands for width and h stands for height.
To calculate the surface area of the box, substitute the given values for l, w and h into the formula and solve:
SA = 2(12)(6) + 2(12)(8) + 2(6)(8)
SA = 144 + 192 + 96
SA = 432 square inches
Therefore, the surface area of the box with a height of 8 inches, a length of 12 inches, and a width of 6 inches is 432 square inches.

Please help me omg just give me m=
Answers
Answer:
m(w) = $25+$20w
Step-by-step explanation:
Let m be the amount saved and w the weeks since the account was opened. Greta starts with $25, so m(0) = $25.
She saves $20 each week, w. m(1), the end of the first week, Greta would have $25 + $20 = $45. This continues for future weeks. We could write this as the follwoing:
m(w) = $25+$20w
Week 5, for example, would end with m(5) = $25+$20*(5)
m(5) = $125.
if g(x)=x-2 and h(x)=x^2-1 , what is ( g•h)(x)
Answers
The composition of two functions, g(x) and h(x), is written as (g•h)(x).
What is function?Function in math is a relationship between two variables where one variable determines the behavior of the other. It is a mathematical expression that assigns each element in a set to a specific output. Functions can be used to represent things like motion, growth, and decay. They are used to create models that can be used to make predictions and analyze data. Functions are used throughout mathematics and science and can be used to solve real-world problems.
This means that the output of function g(x) is used as the input of function h(x). In this case, (g•h)(x) is equal to h(g(x)). So, (g•h)(x) = h(x-2) = (x-2)^2 - 1.

what is the area of the shaded portion in the figure? If, it is a square and the lines are parts of a circle and the side of the square is 10 unit. Give answers in terms of pi.
Answers
A quarter-circle with a radius of 5 has the area: 25π/4, This is where the shaded area in the figure is located.
How do you calculate the size of a circle’s shaded sector?The area of a circle’s sector is calculated as /360o (r²), where r is the radius of the circle and is the angle of the sector.
The little, subtle distinctions between words are distinguished by shades of meaning. The terms “happy” and “ecstatic,” for example, both express emotion, but one is more powerful than the other. When students study shades of meaning, they learn how to effectively articulate how they feel or think. Shade is any gloomy place where sunshine or other strong light is obstructed. A shadow is a dark form that develops on a surface when an item blocks sunlight or other light.
The shaded area in the illustration is a quarter-circle with a radius equal to 10/2, or 5 units, or half the length of the square's side.
The following formula can be used to determine a circle's area:
A = πr²
If pi is present and r is the radius (approximately equal to 3.14).
A quarter-circle with a radius of 5 has the following area:
A = (π × 5²) / 4 = (π × 25) / 4 = 25π / 4
This is where the shaded area in the figure is located.

Help me solve this triangle cuz im at 99
Answers
Answer:
Given: QR = QS (by given)
We are to prove: LS = ZR
Proof:
Since QR = QS, by the SAS (Side-Angle-Side) congruence postulate, we know that triangle QRS is congruent to triangle QSZ (both have two equal sides and included angle).
By the AAS (Angle-Angle-Side) congruence postulate, we know that if two angles of one triangle are congruent to two angles of another triangle, and the included side is congruent, then the two triangles are congruent.
Therefore, by using AAS congruence, we can say that triangle QRS is congruent to triangle QSZ.
By the CPCTC (Corresponding parts of congruent triangles are congruent), we know that if two triangles are congruent, then their corresponding sides are congruent.
Therefore, LS is congruent to ZR.
Therefore, we have proved LS = ZR
Note: The above proof uses the properties of congruence of triangles, if the student is not familiar with this, it might be challenging for them.
