Answer:

y = -1/3x - 7/3

Step-by-step explanation:

To find the slope, you have to plug the values into the slope formula.

y2 - y1/ x2 - x1

-4 - (-2) / 5 - (-1)

-1/3

Now to find the y-intercept, plug in one of the coordinates into the equation.

y = -1/3x + b

-2 = -1/3(-1) +b

-2 = 1/3 + b

-7/3 = b

The equation is y = -1/3x - 7/3.  

The Solution is Y = - ( 1 / 3 )X - 7 / 3 where points are ( 5 , - 4) and ( - 1 , - 2) that passes through a straight line. Y = MX + C is the Formula for Straight line equation.

As per given problem, M is Slope

M = (Y2 - Y1) / (X2 - X1)

M = (- 4 - (- 2)) / ( 5 - (- 1))

M = - (1 / 3)

Now, Line becomes

- 2 = - ( 1 / 3) x (- 1)+ C

- 2 = 1 / 3 + C

C = - (7 / 3)

So, Solution:  Y = - (1 / 3)X - (7 / 3)

Graph-2 shows an exponential growth function.

Exponential functions are used for many real-world applications such as finance, forensics, computer science, and most of the life sciences. Working with an equation that describes a real-world situation gives us a method for making predictions. Seeing their graphs gives us another layer of insight for predicting future events.

Exponential growth is modeled by functions of form f(x)=b^x  where the base is greater than one. Exponential decay occurs when the base is between zero and one. We’ll use the functions f(x)=2^x  and g(x)=(1/2)^x to get some insight into the behavior of graphs that model exponential growth and decay. In each table of values below, observe how the output values change as the input increases by  1.

System of equation can be solved using different method such as elimination method, substitution method and graphical method.

Let's solve the system of equation using elimination method.

2a - 5b = -19

3a + 5b = 9

add equation(ii) from equation(i)

Hence,

5a = -10

divide both sides by 5

a = -10 / 5

a = -2

D THEY TRADED WITH MESOPOTAMIA

Answer:

they did not participate in wars

Step-by-step explanation:

The given integral is ₁∫₀^(π/2) sin²(x)dx.

The trapezoidal rule is given by:(b - a) [(f(a) + f(b))/2]And, the Gauss-Quadrature formula for n = 2 is: ∫ᵇₐ f(x) dx = (b - a) [ w₁ f( [ (b - a)/2 ] gp₁ + (b + a)/2 ) + w₂ f( [ (b - a)/2 ] gp₂ + (b + a)/2 ) ]

Here, a = 0, b = π/2, gp₁ = -0.5773, gp₂ = 0.5773, w₁ = w₂ = 1.

(i) Trapezoidal Rule: The trapezoidal rule with one interval is given by:(b - a) [(f(a) + f(b))/2] = π/4 [sin²(0) + sin²(π/2)] = 0.7854

(ii) Gauss-Quadrature: Using the Gauss-Quadrature formula with n = 2, we get:∫ᵇₐ f(x) dx = (b - a) [ w₁ f( [ (b - a)/2 ] gp₁ + (b + a)/2 ) + w₂ f( [ (b - a)/2 ] gp₂ + (b + a)/2 ) ]= π/2 [ sin²( [ (π/2)/2 ] (-0.5773) + π/4 ) + sin²( [ (π/2)/2 ] (0.5773) + π/4 ) ]= 0.7853Comparing the above two methods, the trapezoidal rule and Gauss-Quadrature method are nearly the same and are close to the exact value.

Exact value = (π/2)/2 - sin(π)/4 = 0.7854Conclusion:Thus, it can be concluded that the given integral using the trapezoidal rule (using only one interval) and Gauss- Quadrature (n=2) is approximately equal to 0.7854.

Jared bought 7 cans of paint. Let the number of red paint cans that Jared bought be x. The number of black paint cans he bought would be 7 - x. A can of red paint costs $3.75 and a can of black paint costs $2.75.

He spent $22 in all. Therefore we can write:3.75x + 2.75(7 - x) = 22 Multiplying out the second term and collecting like terms gives:0.5x + 19.25 = 22Subtracting 19.25 from both sides:0.5x = 2.75Dividing by 0.5:x = 5.5Since Jared can't buy half a can of paint, we should round the answer to the nearest integer. Hence, he bought 5 cans of red paint and 2 cans of black paint. The total cost of the 5 cans of red paint would be 5 x $3.75 = $18.75.The total cost of the 2 cans of black paint would be 2 x $2.75 = $5.50.The total cost of all 7 cans of paint would be $18.75 + $5.50 = $24.25.We spent more than Jared's budget. The value of $24.25 exceeds Jared's budget of $22. Hence, there is a problem with this problem statement.

Alma was definitely correct to say that the tickets are $14 each.

The total amount in dollars the class have for tickets to the science museum

is $140.

The teacher writes as follows:

Alma says the tickets are $14 each.

Mohammed says that 14 students are going for the trip

The teacher divided 140 by 10. This means the number of student in the class is 10 not 14 as Mohammed enunciated.

The teacher divided the total amount available for the ticket($140) by the number of student in the class(10). Then the quotient ($14) is the amount in dollars which each student will pay for the ticket to the science museum.

The coordinates of the midpoint will be (-2,-3).

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

A midpoint is a point that lies on a line connecting two other locations and is in the middle of the line. Given that the midpoint of AB is M(3,-4) and the coordinates of A are (8, -5).

The midpoint will be calculated by using the formula below:-

( 8 + x ) / 2 = 3

( 8 + x ) = 6

x = -8 + 6 = -2

( -5 + y ) / 2 = -4

( -5 + y ) = -8

y =  -8 + 5 = -3

Proved that the remainder when summing digits and dividing by 9 is the same as dividing the number by 9

Let's consider a positive integer n with k digits, which we can write in terms of its digits as

n = d_1 × 10^(k-1) + d_2 × 10^(k-2) + ... + d_k-1 × 10 + d_k

We can then express the sum of the digits of n as

S = d_1 + d_2 + ... + d_k-1 + d_k

We want to show that the remainder when S is divided by 9 is the same as the remainder when n is divided by 9.

First, we can observe that

10 ≡ 1 (mod 9)

Therefore, we can write

10^(k-1) ≡ 1^(k-1) ≡ 1 (mod 9)

10^(k-2) ≡ 1^(k-2) ≡ 1 (mod 9)

...

10 ≡ 1 (mod 9)

Using these congruences, we can simplify the expression for n:

n ≡ d_1 × 1 + d_2 × 1 + ... + d_k-1 × 1 + d_k × 1 (mod 9)

n ≡ d_1 + d_2 + ... + d_k-1 + d_k (mod 9)

n ≡ S (mod 9)

Therefore, n and S have the same remainder when divided by 9.

Chemical kinetics and thermodynamics are two major subfields of chemistry. They both study chemical reactions but focus on different aspects of reactions. This essay aims to explain the differences between chemical kinetics and thermodynamics of a chemical reaction.

Chemical kineticsChemical kinetics is the study of the rates and mechanisms of chemical reactions. It is concerned with how fast chemical reactions occur and what factors affect the rates of reaction. Kinetics tells us about the speed of a reaction, the factors that affect it, and how to control it.Chemical kinetics tells us about the mechanism of chemical reactions and how fast a reaction occurs. Reaction rates are affected by factors such as temperature, concentration, pressure, and the presence of a catalyst. For example, increasing the concentration of reactants leads to an increase in the reaction rate while decreasing the temperature decreases the rate of reaction.ThermodynamicsThermodynamics is the study of energy transfer in a system.

It tells us about the energy changes that occur during a reaction. Thermodynamics tells us whether a reaction will occur spontaneously or not. A reaction is said to be spontaneous if it occurs without external input of energy.Thermodynamics is concerned with the enthalpy (ΔH), entropy (ΔS), and Gibbs free energy (ΔG) changes that occur during a reaction. The Gibbs free energy change tells us whether a reaction is spontaneous or not. If ΔG is negative, the reaction is spontaneous and exergonic.

If ΔG is positive, the reaction is non-spontaneous and endergonic. If ΔG is zero, the reaction is at equilibrium.ConclusionIn conclusion, chemical kinetics is the study of reaction rates and mechanisms, while thermodynamics is the study of energy transfer in a system. Chemical kinetics tells us how fast a reaction occurs and what factors affect its rate, while thermodynamics tells us whether a reaction is spontaneous or not.

The total number of isomers with the formula [Pd(C2O4)2I2]2– is 3150.

There are two parts to this answer: the first part is to determine the coordination number of the central palladium (Pd) atom, and the second part is to determine the number of possible isomers based on the coordination number.

To determine the coordination number, we need to count the number of ligands (the molecules that bind to the central atom) attached to the Pd atom. In this case, we have four oxalate (C2O4) ligands, each of which contributes two atoms (a total of eight atoms), and two iodide (I) ligands, each of which contributes one atom (a total of two atoms). This gives us a total of 10 ligands attached to the Pd atom. Since each ligand can only form one bond with the Pd atom, the coordination number is 10.

Next, we need to determine the number of possible isomers. Isomers are molecules with the same chemical formula but different arrangements of atoms. For this complex ion, there are two types of isomers: geometrical and optical.

Geometrical isomers arise from the fact that the ligands can be arranged around the central atom in different ways. In this case, since there are 10 ligands, there are a total of 10!/[(4!2!2!)x2] possible geometrical isomers, or 3150.

Optical isomers arise when there are non-superimposable mirror images of the molecule. However, since this complex ion has a plane of symmetry, it is achiral and does not have optical isomers.

Therefore, the total number of isomers with the formula [Pd(C2O4)2I2]2– is 3150.
