\(6x - 8 = 2x + 4 \\ 6x - 2x = 4 + 8 \\ 4x = 12 \\ x = 3\)
Answer:
C.) x = 3
Step-by-step explanation:
The diagonals of a rectangle are equal, and QM and PM are both half of the two diagonals. You can now say that 2 * (6x - 8) = 2 * (2x + 4), meaning that 12x - 16 = 4x + 8, where you can add 16 on both sides, then subtract by 4x on both sides to get that 8x = 24. Now divide by 8 on both sides to get that x = 3.
a simple undirected graph has 10 edges. 2 of the vertices are of degree 4, and the rest of the vertices are of degree 3. how many vertices are in this graph?
Answers
To solve this problem, we can use the fact that the sum of the degrees of all vertices in a simple undirected graph is equal to twice the number of edges, Let V be the number of vertices in the graph. We know that 2 of the vertices have degree 4, so the sum of the degrees of all vertices.
However, since the number of vertices in a graph must be a whole number, this answer is not possible. Therefore, there is no simple undirected graph with 10 edges, 2 vertices of degree 4, and the rest of the vertices of degree 3.
Let's solve the problem step by step:
1. In an undirected graph, each edge connects two vertices. Therefore, the sum of the degrees of all vertices is equal to twice the number of edges.
2. In this case, there are 10 edges, so the sum of the degrees of all vertices is 20.
3. Two vertices are of degree 4, so their total degree is 4 * 2 = 8.
4. Let the number of vertices with degree 3 be x. Since the sum of degrees is 20, we can write an equation:
8 + 3x = 20
5. Solve the equation for x:
3x = 12
x = 4
6. Since there are 2 vertices of degree 4 and 4 vertices of degree 3, the total number of vertices in the graph is 2 + 4 =
So, there are 6 vertices in this undirected graph.

The function to model the water used by the car wash on a shorter day is (C) \(4x^{3} +7x^{2} -14x-6\).
What is a function?A function is an expression, rule, or law in mathematics that describes a relationship between one variable (the independent variable) and another variable (the dependent variable).To find the function to model the water used by the car wash on a shorter day:
Given that the amount of water used on normal days is given by the equation:
\(W(x) =5x^{3} +9x^{2} -14x+9\) ......(1)The amount of decrease in water used is modeled by the equation:
\(D(x)=x^{3} +2x^{2} +15\) ......(2)To get the function \(C(x)\) that models the water used by the car wash on a shorter day you subtract equation (2) from equation (1).
\(5x^{3} +9x^{2} -14x+9-(x^{3} +2x^{2} +15)\\5x^{3} +9x^{2} -14x+9-x^{3} -2x^{2} -15\\4x^{3} +7x^{2} -14x-6\)Therefore, the function to model the water used by the car wash on a shorter day is (C) \(4x^{3} +7x^{2} -14x-6\).

Evaluate the indefinite integral as a power series. integral x^6 ln(1 +x)dx f(x) = C + sigma^infinity_n = 0 What is the radius of convergence R? R = Use a power series to approximate the definite integral, I, to six decimal places, i.e., so that the error is less than 0.0000005. integral^0.2_0 1/1 + x^4 dx I =
Answers
Here, the radius of convergence is R = 1.
The steps to find the radius of convergence is as follows:
To evaluate the indefinite integral ∫x^6 ln(1 + x) dx using a power series, we can expand ln(1 + x) as a power series and integrate each term separately. Let's begin:
1. Expand ln(1 + x) as a power series:
ln(1 + x) = x - (x^2)/2 + (x^3)/3 - (x^4)/4 + ...
2. Substitute the power series into the original integral:
∫x^6 ln(1 + x) dx = ∫x^6 (x - (x^2)/2 + (x^3)/3 - (x^4)/4 + ...) dx
3. Distribute the x^6 to each term:
∫(x^7 - (x^8)/2 + (x^9)/3 - (x^10)/4 + ...) dx
4. Integrate each term separately:
= (1/8)x^8 - (1/16)x^9 + (1/27)x^10 - (1/40)x^11 + ...
5. Finally, add the constant of integration, C, to obtain the power series representation of the indefinite integral:
∫x^6 ln(1 + x) dx = (1/8)x^8 - (1/16)x^9 + (1/27)x^10 - (1/40)x^11 + ... + C
The radius of convergence, R, for this power series is the distance from the center of the series to the nearest singularity or point of divergence. In this case, the series is centered around x = 0, and the function ln(1 + x) is defined for -1 < x < 1. Therefore, the radius of convergence is R = 1.
To approximate the definite integral ∫[0, 0.2] (1/(1 + x^4)) dx using the power series, we can integrate the power series term by term and sum the resulting series up to a point where the error is less than 0.0000005. Let's calculate this approximation:
∫[0, 0.2] (1/(1 + x^4)) dx = ∫[0, 0.2] (1 - x^4 + x^8 - x^12 + ...) dx
To find the series that represents the definite integral, we integrate each term and sum them up until the desired accuracy is reached. However, it's important to note that integrating this power series term by term is not a straightforward process, and it does not have a simple closed-form solution.
Therefore, to approximate the definite integral to six decimal places, it would be more suitable to use numerical integration methods like the trapezoidal rule or Simpson's rule. These methods provide accurate approximations for definite integrals without relying on power series expansions.

A tank has a hole in it which leaks water at a rate of 335 ml per minute .If the tank is empty after 4 hours and 25 minutes ,how many litres of water can the tank hold?Give ur answer correct to 1 decimal place
Answers
Change the length of time to minutes:
1 hour = 60 minutes.
4 hours x 60 = 240 minutes + 25 minutes = 265 minutes
Multiply leak rate by total minutes:
265 x 335 = 88,775 ml
Half the tank was 88,775 ml
Multiply by 2 to get the full tank amount:
88775 x 2 = 177,550 ml
Divide by 1000 to change to liters:
177,550 / 1000 = 177.55 liters
Answer to 1 decimal place = 177.6 Liters
a flag pole that is 15 feet tall casts a shadow that is 22 feet long. at the same time of day, the shadow of a nearby tree is 52.3 feet long. how tall is the tree?
Answers
If a flag pole that is 15 feet tall casts a shadow that is 22 feet long. at the same time of day, the shadow of a nearby tree is 52.3 feet long then the tree is 35.5 feet tall
To determine the height of the tree, we need to use ratios and proportions. We know that the flagpole is 15 feet tall and casts a shadow of 22 feet. Using these values, we can create a proportion:
15/22 = x/52.3
To solve for x, we can cross-multiply:
15 x 52.3 = 22 x
x = (15 x 52.3)/22
x = 35.5
Therefore, the tree is 35.5 feet tall.
In mathematics, proportions are often used to compare two quantities. In this case, we used the ratio of the height of the flagpole to the length of its shadow to create a proportion and find the height of the nearby tree. It's important to note that this calculation assumes that both the flagpole and tree are standing vertically and that the angle of the sun's rays is constant. Understanding and using proportions is a valuable skill in many areas of math and science, including geometry, physics, and engineering. By using ratios and proportions, we can compare different quantities and make calculations that help us better understand the world around us.

the total amount of money that jayden made when both paychecks were the same is $99.45
To determine the number of hours Jayden worked the week his paycheck was the same for both jobs, we can solve an equation. The equation we'll use is 14.86h + 17.10 = 99.45. We can subtract 17.10 from both sides, leaving 14.86h = 82.35. Then we cane b divide both sides of the equation by 14.86, which will give us the result of h = 5.55 hours. The total amount of money that Jayden made when both paychecks were the same is 99.45. This can be confirmed by combining his earnings for both jobs, which would be 9.64h + 82.35 + 14.86h + 17.10 = 99.45.

HELP QUICK (5 star and brainliest if correct) If masha buys three roses she will have 7 dollars left. To buy nine roses, Masha will need to borrow 11 dollars from her father. How many dollars does Masha have?
Answers
Let's start by setting up a system of equations to represent the given information:
3r = m - 7
9r = m + 11
where r is the cost of one rose, and m is the total amount of money that Masha has.
We can solve this system of equations using the elimination method:
Multiplying the first equation by 3, we get:
9r = 3m - 21
Subtracting the second equation from this, we get:
0 = -4m - 32
Simplifying, we get:
m = -8
Therefore, Masha has $-8, which means she owes money. This indicates that there may be an error in the problem statement or data provided.
Answer:
Masha has 16 dollars.
Step-by-step explanation:
3x + 7 = Masha's total money
9x = Masha's total money + 11 (after borrowing)
We can use the first equation to find the value of 3x, which is Masha's total money if she buys three roses:
3x + 7 = Masha's total money
3x + 7 = Masha's total money
3x = Masha's total money - 7
We can substitute the second equation to solve for Masha's total money:
9x = Masha's total money + 11
9x = (3x + 7) + 11
9x = 3x + 18
6x = 18
x = 3
Now we know that one rose costs 3 dollars. We can use the first equation to find Masha's total money if she buys three roses:
3x + 7 = Masha's total money
3(3) + 7 = Masha's total money
9 + 7 = Masha's total money
Masha's total money = 16
