Fundamental Theorem of Line Integral, also called the Gradient theorem, tells us that line integrals through gradient fields are path independent and depend only on the initial and final values. correct answer is option 4 and 5
What does the Line Integrals Fundamental Theorem teach us?
In general, this theorem, like the Fundamental Theorem of Calculus, states that if we integrate a "derivative-like function" (f′ or f), the outcome depends only on the values of the original function (f) at the endpoints.
It is referred to be a conservative vector field if a vector field F is the gradient of a function, F=f.
The line integral of a gradient vector field depends only on the initial and terminal points of the path.
The workdone by gradient vector field is independent of path..

In angle JKL, if angle L is thirteen more than angle k and angle j is seven more than six times angle k, find the measure of each angle
The measure of Angle JKL mJ = 159.4°, mK = 3.8°, and mL = 16.8°.
What is the measure if Angle JKL?A ray is rotated about its endpoint, or vertex, to create an angle. The rotational difference between a ray's starting and ending positions is what is measured by an angle's degree.
If x = mJ, y = mK, and z = mL, then
Angle L exceeds Angle K by thirteen, hence z = y + 13 is the result (1)
Since angle J exceeds angle K by a factor of 7, x = 7(6y) = 42y (2)
X + Y + Z = 180 because the triangle's angles add up to 180°.
In place of (1) and (2) (3).
42y + y + (y + 13) = 180
44y + 13 = 180
44y = 167
y = 3.8°
x = 42y = 159.4°
z = y + 13 = 16.8°
The answer is that mJ = 159.4°, mK = 3.8°, and mL = 16.8°.

Rewrite 177+ 563 = 740 using the Commutative Law of Addition.
O(177 +563) = 740
563 +177 740
740 563 = 177
563 = 177 + 740
Answer: The Commutative Law of Addition states that the order in which numbers are added does not affect the result. This means that for any two numbers a and b, we have a + b = b + a.
We can use the Commutative Law of Addition to rewrite the equation 177 + 563 = 740 as follows:
177 + 563 = 740
563 + 177 = 740
Both of these equations are equivalent to the original equation, because they represent the same mathematical statement.
Note that in the first equation, we simply reordered the terms of the original equation. In the second equation, we added the numbers in a different order, but the result is still the same.
The other equations you provided are not equivalent to the original equation and do not use the Commutative Law of Addition.
Find the area of $\triangle ABC$ with vertices $A\left(2,\ -2\right)$ , $B\left(4,\ -2\right)$ , and $C\left(6,\ -11\right)$ .
The area of $\triangle ABC$ is
square units.
The area of the triangle from the vertices is 27 square units
How to determine the area of the triangle?From the question, we have the following parameters that can be used in our computation:
$A\left(2,\ -2\right)$ , $B\left(4,\ -2\right)$ , and $C\left(6,\ -11\right)$ .
Represent the vertices properly
So, we have
A = (2, -2)
B = (4, -2)
C = (6, -11)
The area of the triangle is calculated using
Area = 0.5 * |Ax(By - Cy) + Bx(Ay - Cy) + Cx(Ay - By)|
Substitute the known values in the above equation, so, we have the following representation
Area = 0.5 * |2 * (-2 + 11) + 4 * (-2 + 11) + 6 * (-2 + 2)|
Evaluate the sum of products
Area = 0.5 * |54|
Remove the absolute bracket
Area = 0.5 * 54
Evaluate
Area = 27
Hence, the area of ABC with vertices is 27 square units

A standard television screen has a 4:3 aspect ratio between the width and the height of the viewable screen. What would be the height of Television that is 16 inches wide?
The standard height of the television is 12 inches.
What are ratios?
By comparing two amounts of the same units, the ratio can be used to calculate how much of one item is included in the other.
The given ratio is 4:3. Let us take a variable 'x' such that 4x=16 and 3x=height.
We find x from 4x=16
x=4
Now putting the value of x in 3x, we get 12 inches.

The standard height of the television is 12 inches.
The aspect ratio of a screen is the ratio of the width to the height. In the case of a television screen with a 4:3 aspect ratio, the width is 4 units and the height is 3 units.
If we let "h" represent the height of the television screen, we can set up the following equation:
4:3 = 16:h
To solve for "h", we can cross-multiply to get:
4h = 48
Dividing both sides by 4, we get:
h = 12
So the height of a television screen that is 16 inches wide and has a 4:3 aspect ratio is 12 inches.
what is aspect ratio?
The aspect ratio of a screen is the ratio of the width to the height of the viewable area of the screen. It is usually expressed as two numbers separated by a colon, such as 16:9 or 4:3.
Aspect ratios are used in a variety of applications, including television screens, computer monitors, and movie theaters. Different aspect ratios are used for different types of content, and some screens can be adjusted to display content in different aspect ratios.

A line is drawn to model the relation ship between the number of weeks and the change in price. Is the slope of this line positive or negative? Explain.
If the slope is negative, the function is downward-sloping because y falls off as x rises. If the slope is zero, y remains constant—a horizontal line—and does not vary.
What is slope?A line's steepness and direction are measured by the line's slope.
Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all
Any two different points on a line can be used to calculate the slope of any line.
A line's slope is determine by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively.
Two locations located on a straight line can be used to determine a line's slope. We can use the slope of line formula if we know the two spots' coordinates. These two points' coordinates should be-
P1 = (x1, y1) and P2 = (x2, y2)
Hence, If the slope is negative, the function is downward-sloping because y falls off as x rises. If the slope is zero, y remains constant—a horizontal line—and does not vary.

The interest rate would be 13%.
What is the simple interest?
Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest. For example, when a person takes a loan of Rs. 5000, at a rate of 10 p.a. for two years, the person's interest for two years will be S.I. on the borrowed money.
To find the interest rate, we can use the formula for simple interest:
I = Prt
where I is the amount of interest earned, P is the principal (the initial amount of money deposited), r is the interest rate, and t is the time in years.
In this case, we know that I = $3,900, P = $10,000, and t = 3 years. We can use this information to solve for r:
I = Prt
$3,900 = $10,000r3
r = $3,900/($10,000*3)
r = 0.13 or 13%
Hence, the interest rate is 13%.

What is inequality?In mathematics, a relationship between two expressions or values that are not equal to each other is called "inequality".
Here,
The number of rooms Joe company needs is 50. Let the number of rooms needed be n, this can be represented by the inequality:
n ≥ 50
Joe has already reserved 16 rooms, therefore the number of additional rooms needed to be reserved = 50 - 16 = 34 rooms. At least 34 rooms have to be reserved, if B is the number of additional blocks that Joe reserves, the inequality is:
B ≥ 34
Each block contains 8 rooms therefore the minimum number of block (a) needed to be reserved = 34/8 = 4.25 = 5 to the next whole number. Therefore the minimum number of blocks needed is given as:
a ≥ 5
Since each block cost $900, let c represent the minimum amount of money needed, therefore the least amount of money needed is given as:

There are many intriguing accounts of what occurs when you mix two of them together. Here are a few instances:
Each isometry may be classified as belonging to one of the five classes listed below.
a consideration,an interpretationthe rotationa reflection of a glide,The map of identity.The identity is the combination of two reflections along the same line.
Translation is the combination of two reflections in dissimilar but related directions. Rotation is the result of two reflections in non-parallel lines.
A gliding reflection is made up of a reflection over a line plus a translation along a non-perpendicular line (and not a reflection).
A reflection is made up of a translation along a perpendicular line and a reflection across a line (and not a glide reflection).
There are fascinating things to say about what occurs when you combine two isometries dependent on the types of the isometries that you combine, but it does not change the fact that the five types are all distinct from one another. I could go on, but I think you get the point now.
