Point e is drawn on the graph so that line ef is parallel to line cd. If the coordinates of point e are (, y), what is the value of y? −8 −4 0 8.
Answers
Based on the graph given, it can be deduced from the computation that the value of y will be -8.
Point C is given as (-10 , -2) and D = (10 , 6)
The Slope of line CD = ( 6 - (-2) /( 10 - (-10) = 8/20 = 2/5
Since EF is parallel to line CD , the slope of EF = 2/5
Equation y = (2/5)x + c
5y = 2x + 5c
It passes through F ( 6 , -4)
= 5(-4) = 2*6 + 5c
= -20 = 12 + 5c
5c = -32
5y = 2x - 32
Point E ( - 4 , y)
5y = 2(-4) - 32
5y = -8 - 32
5y = -40
y = -8
Therefore, the value of y is -8.

Which of the following about a contour line is false?.
Answers
The statement from the given options that is false about contour lines is;
Option B; Contour lines can cross.
The missing options are;
A. Contour lines form a "V" that points upstream.
B. Contour lines can cross.
C. Contour lines connect points of equal elevation.
D. Concentric contour lines may indicate a hill.
To answer the question, we need to first understand what contour lines are.
Contour lines are lines that are used on topographic maps to show elevations, landform shapes, and slope stiffness. It can also be used to show population density and average income.
An example of a contour lines are Isotherms which means lines of equal temperature.
Now, contour lines do not cross each other but instead will form a v-shape.

What factors would have the least effect on a region’s climate?.
Answers
Answer:
Longitude and Population Density
Explanation:
Longitude
Longitude won't have much effect because it is just across the earth in E to W. (east to west). While, Latitude will affect the Earth because there is something called a Equator, which is USUALLY hot, and the Polar zones, which are mostly Cold.
Population Density
Population Density won't affect much because the amount of carbon dioxide a person produces is pretty less. But yeah, the factories make a lot of more Carbon Dioxide so that is why they will be producing more than the people. But people can't produce so much to warm up their environment.

Answer:
1400 years
Explanation:
Let us convert everything to the same units first. For simplicity, I will convert everything to millimeters.
7 m = 7 m x (1000 mm / 1 m) = 7000 mm
Since the rate is 5, we can use this equation:

F(x, y) = e−x + y2, e−y + x2 , c consists of the arc of the curve y = cos(x) from − ???? 2 , 0 to ???? 2 , 0 and the line segment from ???? 2 , 0 to − ???? 2 , 0.
Answers
Given that y = cos(x) makes up part of the boundary of C, I suspect you mean the given points to be (-π/2, 0) and (π/2, 0).
I also assume the given vector field is
[tex]\vec F(x,y) = \left\langle e^{-x} + y^2, e^{-y} + x^2 \right\rangle[/tex]
Since [tex]\vec F[/tex] has no singularities on C or in its interior, Green's theorem applies:
[tex]\displaystyle \int_C \vec F(x,y) \cdot d\vec r = \iiint_D \frac{\partial(e^{-y}+x^2)}{\partial x} - \frac{\partial(e^{-x}+y^2)}{\partial y} \, dA = 2 \iiint_D (x + y) \, dA[/tex]
where D is the interior of C, the region
[tex]D = \left\{ (x, y) : -\dfrac\pi2 \le x \le \dfrac\pi2 \text{ and } 0 \le y \le \cos(x) \right\}[/tex]
The integral then reduces to
[tex]\displaystyle 2 \iint_D (x + y) \, dA = 2 \int_{-\frac\pi2}^{\frac\pi2} \int_0^{\cos(x)} (x + y) \, dy \, dx[/tex]
[tex]\displaystyle 2 \iint_D (x + y) \, dA = 2 \int_{-\frac\pi2}^{\frac\pi2} \left( x\cos(x) + \frac12 \cos^2(x) \right) \, dx[/tex]
[tex]\displaystyle 2 \iint_D (x + y) \, dA = 2 \int_{-\frac\pi2}^{\frac\pi2} \left( x\cos(x) + \frac{1 + \cos(2x)}4 \right) \, dx[/tex]
[tex]\displaystyle 2 \iint_D (x + y) \, dA = \frac12 \int_{-\frac\pi2}^{\frac\pi2} \left( 4x\cos(x) + 1 + \cos(2x) \right) \, dx[/tex]
Since 4x cos(x) is an odd function over the symmetric interval [-π/2, π/2], its contribution to the integral is 0, and the remaining integral is trivial.
[tex]\displaystyle 2 \iint_D (x + y) \, dA = \frac12 \int_{-\frac\pi2}^{\frac\pi2} \left( 1 + \cos(2x) \right) \, dx = \boxed{\frac\pi2} [/tex]

Would sound waves travel slower through air at the north pole or at the equator?.
Answers
yes they would travel slower at the north pole than the equator because the air is more dense and is harder to pass through
Yes, sound waves would travel slower at the North Pole than at the equator because the air is denser and is harder to pass through.
What are equators?The Equator is the midline of the earth. A vibration results in a sound. We refer to these motions as "sound waves." Sound waves require a specific medium to travel through. The three different types of media are solid, liquid, and gas.
Keep in mind that since a "solid medium" is denser than the other two, sound waves move through it more quickly. Because water is more densely packed with particles than gas is, sound waves travel faster in liquid than in gas (such as air).
Therefore, yes, because the air is heavier and more difficult to get through at the North Pole than it is at the Equator, sound waves would move more slowly there.

More than half of the population of Europe was killed due to his plague, which immediately creates a shortage of labor. Shortage of labor, including agricultural ones, immediately meant that the living ones would receive a higher wage, to the consternation of the landowners who pushes for legislation that would return the status quo to how it was prior to the Black Death. This enrages the peasants who worked for them; manifesting in several revolts from May to November 1380.

Which best describes the first law of thermodynamics as compared to the second law of thermodynamics?.
Answers
Answer:
The first law describes how thermal energy is conserved but not the direction it moves.
Thermodynamics is demonstrated as the branch of physics that deals with the associations or relationships between heat and other energy forms like mechanical, chemical, and electrical).
As per the question, the first law discusses that heat is a kind or form of energy and thus, processes associated with thermodynamics are subject to energy conservation principle. Therefore, heat energy can neither be destroyed nor created but rather transferred to one place to another and converted to and from other energy forms.
Thus, the first law of thermodynamics is distinct from the second law as 'the former describes how thermal energy can be conserved to and from other forms of energy and not the direction in which it moves' while the second law focuses on entropy.
