A directed graph can be used to determine whether a relation R on a finite set A is asymmetric or not by checking whether there is any pair of elements (a, b) in R such that both (a, b) and (b, a) are present in R.
If such a pair exists, then the relation is not asymmetric because it violates the condition for asymmetry, which states that for any (a, b) in R, (b, a) cannot be in R.
In the directed graph, this means that there is a directed edge from a to b and also a directed edge from b to a. This would result in a cycle in the directed graph, which is not allowed in an asymmetric relation.
If there are no such pairs in R, then the relation is asymmetric, and the directed graph will not contain any cycles. Therefore, the directed graph can be a helpful tool to quickly determine if a relation is asymmetric or not, especially for larger sets A.

you are given the following information about a population:• There are two alleles: C and c.• C codes for green hair and c codes for white hair.• C is dominant over c.• The frequency of the c allele is 0.3.• The population is comprised of 100 individuals.Assuming the population is in Hardy-Weinberg equilibrium, how many individuals have green hair?
In this population of 100 individuals, approximately 49 individuals will have green hair due to the dominant allele CC and approximately 42 individuals will have green hair due to the dominant allele Cc. The total number of individuals with green hair is 49 + 42 = 91.
What is the quadratic equation?
A quadratic equation in one variable is a mathematical sentence of degree 2 that can be written in the following standard form. a+ bx + c = 0, where a, b, and c are real numbers and a 0.
The Hardy-Weinberg equilibrium is an idealized model of a population that assumes that the frequency of alleles remains constant from generation to generation in the absence of external forces.
According to this model, the frequency of a particular genotype can be calculated using the following formula:
p² + 2pq + q² = 1
where p is the frequency of the dominant allele (C) and q is the frequency of the recessive allele (c). In this case, p = 1 - q = 1 - 0.3 = 0.7, and q = 0.3.
The frequency of individuals with the genotype CC (green hair) is given by p², or 0.7² = 0.49.
The frequency of individuals with the genotype Cc (green hair) is given by 2pq, or 2 * 0.7 * 0.3 = 0.42.
Hence, in this population of 100 individuals, approximately 49 individuals will have green hair due to the dominant allele CC and approximately 42 individuals will have green hair due to the dominant allele Cc. The total number of individuals with green hair is 49 + 42 = 91.

In a certain molecule, atom X is bonded to H. The force of attraction for X’s nucleus on the shared valence electron is 2.2 x 10-8 N. If the radius of atom X is 1.02 x 10-10 m, predict the number of protons in X’s nucleus. Predict the identity of atom X. Show your set-up.
An atom X has 3 protons in its nucleus. An atomic number of 3 corresponds to the element lithium (Li).
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We can use Coulomb's law to predict the number of protons in X's nucleus. Coulomb's law states that the force of attraction between two charges is proportional to the product of the charges and inversely proportional to the square of the distance between them.
⇒ F = k (q₁ q₂) / r²
Where, F is the force of attraction, k is the Coulomb constant (8.99 x 10⁹ Nm²/C²), q₁ and q₂ are the magnitudes of the charges, and r is the distance between them.
We can rearrange the equation to solve for the charge:
⇒ q₂ = (F * r²) / (k * q₁)
In this case, q1 is the charge on the electron, which is -1.60 x 10⁻¹⁹ C. The radius of atom X, r, is given, and the force of attraction, F, is also given.
So, we have:
⇒ q₂ = (2.2 x 10⁻⁸ N * (1.02 x 10⁻¹⁰ m)²) / (8.99 x 10⁹ Nm²/C^2 * -1.60 x 10⁻¹⁹ C)
Solving for q₂, we find that;
q₂ = +5.4 x 10⁻¹⁹ C.
This is the charge on the nucleus of atom X. The number of protons in the nucleus of atom X can be found by dividing the charge by the charge of a proton:
⇒ N = q₂ / qp
Where N is the number of protons and qp is the charge on a proton, which is +1.60 x 10⁻¹⁹ C.
So, we have:
N = (5.4 x 10⁻¹⁹ C) / (1.60 x 10⁻¹⁹ C) = 3.375
Hence, the number of protons must be a whole number, the closest whole number to 3.375 is 3. This means that atom X has 3 protons in its nucleus. The identity of atom X can be determined based on its atomic number, which is equal to the number of protons in its nucleus. An atomic number of 3 corresponds to the element lithium (Li).

Two identical rectangular prisms and two identical cubes are joined.
Answer the questions to find the new solid’s surface area.
The new solid's surface area, which is 490 cm², is created by combining two identical cubes, each of which has a surface area of 294 cm².
What is the Total Surface Area of a Cube?The total area of a cube's faces that cover it is the surface area of the object. The cube's surface area is calculated as six times the square of its side lengths. 6a², where an is the cube's side length, serves as its representation. In essence, it is the overall surface area.
Total surface area of a cube = 6a², where a is the length of each of the sides.
Let the surface area of each identical cube = 294 cm²
The length of each side be
6a² = 294
simplifying the above equation, we get
a² = 294/6
a² = 49
a = √49
a = 7 cm
Surface area of the new solid
= surface area of the two identical cubes - 2(area of the surface where both are joined)
Surface area of the new solid = 2(294) - 2(7²) = 490 cm²
Therefore, the surface area of the new solid be 490 cm².

The complete question
A model rocket is launched with an initial upward velocity of 50m/s. The rocket's height h (in meters) after t seconds is given by the following. h=50t-5t².
Find all values of t for which the rockets height is 20 meters.
The values of t for which the rockets height is 20 meter are, (10 + 2√21) / 2 and (10 - 2√21) / 2
What is velocity ?Velocity is a vector quantity that represents the rate of change of an object's position. It is defined as the derivative of the position vector with respect to time and has units of meters per second (m/s). Velocity includes both speed and direction, and is an important concept in physics and engineering.
We can find the values of t for which the rocket's height is 20 meters by setting h equal to 20 and solving for t.
h = 50t - 5t² = 20
Expanding the equation, we have:
50t - 5t² = 20
Adding 5t² to both sides:
50t = 20 + 5t²
Dividing by 5 both the sides,
10t = 4 + t²
t² - 10t + 4 = 0
t = (10 + 2√21) / 2
and t = (10 - 2√21) / 2
So the values of t for which the rocket's height is 20 meters are
(10 + 2√21) / 2 and (10 - 2√21) / 2

Find the exact length of the midsegment of the trapezoid with the vertices S(-2, 4), T(-2,-4), U(3,-2), V(13,10)
The exact length of the midsegment of the trapezoid is √29 units.
What is Distance?The length along a line or line segment between two points on the line or line segment.
Distance=√(x₂-x₁)²+(y₂-y₁)²
The midsegment of a trapezoid is the line segment that connects the midpoints of the two non-parallel sides. Let's first find the midpoints of the sides SU and TV.
The midpoint of SU can be found as:
((Sx + Ux)/2, (Sy + Uy)/2) = ((-2 + 3)/2, (4 - 2)/2) = (1/2, 1)
Similarly, the midpoint of TV can be found as:
((Tx + Vx)/2, (Ty + Vy)/2) = ((-2 + 13)/2, (-4 + 10)/2) = (5.5, 3)
Now we can find the length of the midsegment that connects these two midpoints.
Distance=√(x₂-x₁)²+(y₂-y₁)²
So the length of the midsegment is:
d = √(5.5 -0.5)²+ (3 - 1)²)
= √25 + 4= = √29
Therefore, the exact length of the midsegment of the trapezoid is √29 units.

To graph the equation y = 12.3x, identify and locate the vertical and horizontal intercepts. To do this, set x equal to zero to find the vertical intercept, which is y = 12.3(0) = 0. Then, set y equal to zero to find the horizontal intercept, which is x = 0/12.3 = 0.
To graph the equation y = 12.3x, we need to identify and locate the vertical and horizontal intercepts. The vertical intercept is found by setting x equal to zero, which gives us y = 12.3(0) = 0. This means the vertical intercept is at the point (0,0). The horizontal intercept is found by setting y equal to zero, which gives us x = 0/12.3 = 0. This means the horizontal intercept is at the point (0,12.3). We can then plot these two points to graph the equation. Drawing a line through the points, we can see that the equation is a straight line that goes through the origin with a positive slope, meaning that as x increases, so does y. This line has a y-intercept of 0 and an x-intercept of 12.3.

1st “select an answer” is either miles or dollars
2nd “select an answer” is either miles or dollars
Based on the given information:
The linear equation between cost of truck rent and distance is: C(d) = 22.95 + 0.72dThe cost needed to drive the truck for 15 miles is $33.75With budget of $110, you can drive the truck up to 120.9 milesFrom the case we know that the cost of rent a truck was charged by 2 rules:
Cost per truck = fixed cost = $22.95
Cost per miles distance = variable cost = $0.72 per mile
Both costs can be formulated as a linear equation:
C(d) = 22.95 + 0.72d
where we take the fixed cost of $22.95 as the y-intercept and the variable cost of $0.72 per mile as the slope of the line.
Based on our linear equation, we can try to find the cost needed to rent a truck and drive it for 15 miles:
C(15) = 22.95 + 0.72(15)
C(15) = 22.95 + 10.8
C(15) = $33.75
We can use the same approach to find the available distance for our budget of $110:
C(d) = 22.95 + 0.72d
110 = 22.95 + 0.72d
0.72d = 87.05
d = 120.9
