Green's Theorem to evaluate the line integral along the given positively oriented curve. is -1215.
To evaluate the line integral using Green's Theorem, we first need to calculate the double integral of the curl of the vector field over the region enclosed by the given curve.
Let's denote the vector field as F(x, y) = (xy^2, 5x^2y). The curl of F is given by ∇ × F = (∂Q/∂x - ∂P/∂y), where P = xy^2 and Q = 5x^2y.
∂Q/∂x = 10xy
∂P/∂y = 2xy
Now, we can compute the line integral using Green's Theorem, which states that the line integral of a vector field F around a positively oriented curve C is equal to the double integral of the curl of F over the region D enclosed by C:
∫C (P dx + Q dy) = ∬D (∂Q/∂x - ∂P/∂y) dA
In this case, the region D is the triangle with vertices (0,0), (3,3), and (3,6). To evaluate the double integral, we can use an appropriate coordinate system, such as Cartesian or polar coordinates, depending on the complexity of the region D.
Since the triangle is simple and the integrals can be easily evaluated in Cartesian coordinates, we can proceed with that. The limits of integration for x are from 0 to 3, and for y, it is from y = x to y = 6.
∬D (∂Q/∂x - ∂P/∂y) dA = ∫[0,3] ∫[x,6] (10xy - 2xy) dy dx
Integrating with respect to y first:
∫[0,3] [(5xy^2 - xy^2) evaluated from y=x to y=6] dx
∫[0,3] [(5x(6)^2 - x(6)^2) - (5x(x)^2 - x(x)^2)] dx
∫[0,3] [180x - 30x^3] dx
[90x^2 - 7.5x^4] evaluated from 0 to 3
[810 - 2025] - [0 - 0]
-1215
Therefore, the line integral along the given curve is -1215.

2(x+4)+2=5x+1 solve for x
Answer:
x = 3
Step-by-step explanation:
2(x+4) + 2 = 5x + 1
2x + 8 + 2 = 5x + 1
2x + 10 = 5x + 1
-3x + 10 = 1
-3x = -9
x = 3
To solve for x, we need to simplify the equation and isolate the variable. Let's proceed with the given equation:
2(x + 4) + 2 = 5x + 1
First, distribute the 2 to the terms inside the parentheses:
2x + 8 + 2 = 5x + 1
Combine like terms on the left side:
2x + 10 = 5x + 1
Next, let's move all terms containing x to one side of the equation and the constant terms to the other side. We can do this by subtracting 2x from both sides:
2x - 2x + 10 = 5x - 2x + 1
Simplifying further:
10 = 3x + 1
To isolate the x term, subtract 1 from both sides:
10 - 1 = 3x + 1 - 1
9 = 3x
Finally, divide both sides of the equation by 3 to solve for x:
9/3 = 3x/3
3 = ×
Therefore, the solution to the equation is x = 3.

The function f(x) square root is compressed horizontally by a factor of 3 and , translated up 2 units. Write the equation of the transformed function.
The equation of the transformed function, after being compressed horizontally by a factor of 3 and translated up 2 units, is g(x) = sqrt(x/3) + 2.
If f(x) is a function, and we want to compress it horizontally by a factor of 3 and translate it up 2 units, we can apply the following transformations:
Horizontal compression by a factor of 3 means that we need to replace x with x/3 in the function.
Translation up 2 units means that we need to add 2 to the function.
The equation of the transformed function is g(x) = sqrt(x/3) + 2, which represents a function that has been compressed horizontally by a factor of 3 and translated up 2 units from the original function f(x) = sqrt(x).
Therefore, the equation of the transformed function is:
g(x) = sqrt(x/3) + 2
Note that g(x) represents the transformed function, and we have used the square root symbol to indicate that the function is the square root of x/3.

Can a normal approximation be used for a sampling distribution of sample means from a population with μ = 56 and σ = 10, when n = 9? Answer 5 Polnts Yes, because the sample size is less than 30. No, because the sample size is less than 30 Yes, because the mean is greater than 30 No, becouse the standard deviation is too small
Yes, a normal approximation can be used for a sampling distribution of sample means from a population with μ = 56 and σ = 10 when n = 9. Since the sample size is less than 30 and the population distribution is normal,
we can use the central limit theorem, which allows us to assume that the distribution of sample means is approximately normal.In order to use the normal approximation, we need to verify whether the sample size is large enough for a normal distribution to be a good approximation. According to the central limit theorem, if the sample size is less than 30, the normal approximation is valid if the population distribution is approximately normal. Since the population distribution is normal,
we can use the normal approximation for a sample size of n=9. Thus, the correct answer is: Yes, because the sample size is less than 30.

Triangle EFG has vertices E(-4, 1), F(-3,-2), and G(2, 1). Find the coordinates of the image of points E
F, and G'after a translation 2 units down.
The coordinates of the image of point E after a translation 2 units down are (-4, -1).
The coordinates of the image of point F after a translation 2 units down are (-3, -4).
The coordinates of the image of point G after a translation 2 units down are (2, -1).
How to translate coordinates?To translate coordinates in a two-dimensional plane, you need to know the translation vector. A translation vector is a pair of numbers (a, b) that indicates the amount of movement in the x-direction and y-direction.
To translate a point (x, y) by the translation vector (a, b), you can use the following formulas:
x' = x + a
y' = y + b
Where x' and y' are the new coordinates of the point after the translation.
A translation is a transformation that moves a figure a certain distance in a certain direction without rotating or reflecting it. In this case, we are asked to translate the triangle EFG 2 units down. This means that we need to move the triangle down 2 units on the y-axis.
To translate a point (x, y) down 2 units, we can add -2 to the y-coordinate. The new coordinates of the point will be (x, y - 2).
The coordinates of E are (-4, 1), so the coordinates of E' after the translation are (-4, 1-2) = (-4,-1)
The coordinates of F are (-3,-2), so the coordinates of F' after the translation are (-3,-2-2) = (-3,-4)
The coordinates of G are (2, 1), so the coordinates of G' after the translation are (2,1-2) = (2,-1)
So the new coordinates for the triangle EFG' after the translation are:
E'(-4,-1)
F'(-3,-4)
G'(2,-1)
It's important to notice that the x-coordinates didn't change because we are only translating the triangle down, on the y-axis.

The equation of the vertical asymptote of the function \(g(x)=4log_{2} (x-2)+5\) is x=2.
What is vertical asymptote of a function?Vertical asymptotes are vertical lines that represent the zeros of a rational function's denominator. Asymptotes can also occur in other situations, such as logarithms. It occurs at the x-value that is outside the domain of the function, therefore the graph can never cross it.
How to find vertical asymptotes from graph?There may be a vertical asymptote along the vertical line if a portion of the graph is about to turn vertical. At the point of x along which you discovered the vertical asymptote, the function's value changes to either ∞ or -∞. A vertical asymptote, however, must never touch the graph.

For example the point graphed is (1,4) 1 is the x value and 4 is the y value.
4/1 = 4
Answer: 4
Step-by-step explanation:
The constant of proportionality is the slope of a line that goes through the origin.
The slope/constant of proportionality is how much the Y increases every time the X increases by 1. Since your graph has the point (1, 4) labeled, the Y goes up 4 units for every 1 unit the X increases by.
re-prove the result of problems iv, question 13 that (a, 6) [a, b] = ab for positive integers a and b using the fundamental theorem of arithmetic.
Using the fundamental theorem of arithmetic, we have proven that (a, 6) [a, b] = ab for positive integers a and b.
To prove that (a, 6) [a, b] = ab for positive integers a and b using the fundamental theorem of arithmetic, we'll proceed as follows:
Step 1: Prime factorization of a and 6:
Using the fundamental theorem of arithmetic, we can write a and 6 as products of their prime factors:
a = p1^k1 * p2^k2 * ... * pn^kn,
6 = 2^1 * 3^1.
Step 2: Finding the greatest common divisor (a, 6):
To find the greatest common divisor (a, 6), we consider the common prime factors between a and 6 and take the minimum exponent for each prime factor. In this case, the common prime factor is 2 with an exponent of 1. Therefore, (a, 6) = 2^1.
Step 3: Prime factorization of [a, b]:
Using the fundamental theorem of arithmetic, we can write [a, b] as a product of its prime factors:
[a, b] = p1^m1 * p2^m2 * ... * pn^mn.
Step 4: Finding the least common multiple [a, b]:
To find the least common multiple [a, b], we consider the prime factors between a and b and take the maximum exponent for each prime factor. In this case, we have already determined that the common prime factor is 2 with an exponent of 1. Therefore, [a, b] = 2^1.
Step 5: (a, 6) [a, b] = ab:
Substituting the values we found, we have:
(a, 6) [a, b] = 2^1 * 2^1 = 2^2 = 4.
Since ab = 4, we have proven that (a, 6) [a, b] = ab for positive integers a and b using the fundamental theorem of arithmetic.
