Answer:
A law stating that the square of a side of a plane triangle is equal to the sum of the squares of the other two sides minus twice the product of the other sides multiplied by the cosine of the angle between them.As we learned, sine is one of the main trigonometric functions and is defined as the ratio of the side of the angle opposite the angle divided by the hypotenuse. It's important for finding distances or height and can also be used to find angle measures, which are measured in radians.Law of cosines signifies the relation between the lengths of sides of a triangle with respect to the cosine of its angle. ... If ABC is a triangle, then as per the statement of cosine law, we have: a2 = b2 + c2 – 2bc cos α, where a,b, and c are the sides of triangle and α is the angle between sides b and c.RULE OF LAW Defined
The rule of law is a principle of governance in which all persons, institutions and entities, public and private, including the State itself, are accountable to laws that are publicly promulgated, equally enforced and independently adjudicated, and which are consistent with international human rights norms and standards. It requires, as well, measures to ensure adherence to the principles of supremacy of law, equality before the law, accountability to the law, fairness in the application of the law, separation of powers, participation in decision-making, legal certainty, avoidance of arbitrariness and procedural and legal transparency.A rule of law framework that includes the following:
Constitution or its equivalent, as the highest law of the land;A clear and consistent legal framework, and implementation thereof;Strong institutions of justice, governance, security and human rights that are well structured, financed, trained and equipped;Transitional justice processes and mechanisms; A public and civil society that contributes to strengthening the rule of law and holding public officials and institutions accountable.[tex]\color{yellow}{}[/tex]

Answer:
[tex]\boxed {\boxed {\sf d= \sqrt{34}}}[/tex]
Step-by-step explanation:
We want to find the distance between two points, so the following formula is used.
[tex]d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
Where (x₁, y₁) and (x₂, y₂) are the points we are finding the distance between.
We are given the points (-2, -1) and (3,2). If we match the corresponding value and variable we see that:
x₁= -2 y₁= -1x₂= 3 y₂= 2Substitute the values into the formula.
[tex]d= \sqrt {(-2-3)^2+(2--1)^2[/tex]
Solve the parentheses.
-2 -3 = -5 2--1 = 2+ 1 = 3[tex]d= \sqrt{(-5)^2+(3)^2[/tex]
Solve the exponents.
(-5)²= -5*-5= 25 (3)²= 3*3=9[tex]d= \sqrt{25+9}[/tex]
Add.
[tex]d= \sqrt{34}[/tex]
This radical cannot be simplified, so the distance between the two points is √34 and choice 3 is correct.

A ramp is used so a trolley can be wheeled on to a platform.
The cross-section of the ramp is drawn as a right-angled triangle with
the unknown height labelled as x.
1 Is the unknown length in this triangle (shown as x) the length of
the hypotenuse? Explain ur answer.
Answer:
The hypotenuse is sqrt ( 2x^2)
Step-by-step explanation:
Given a right angled triangle, we can find the hypotenuse of a triangle using the Pythagorean theorem which says that c^2 = a^2 + b^2, where a is the length, b is the perpendicular height and c is the hypotenuse. The length of the triangle (l) is x and the height of the triangle is also x. By substituting the values,
c^2 = x^2 + x^2 = 2x^ 2
There are two possible answers to c but the hypotenuse cannot be negative.
Hence,
c = Sqrt (2x^2)
A parabola and its focus are shown on the graph. The vertex of the parabola is at (0,0).
On a coordinate plane, a parabola opens to the right. It has a vertex at (0, 0) and a focus (3, 0).
What is the equation of the directrix of the parabola?
y = 3
y = –3
x = 3
x = –3
Answer:
y = -3
Step-by-step explanation:
the length from directrix to vertex is equal to the length from focus to the vertex.
Answer: y=-3
Step-by-step explanation: y = -3 Step-by-step explanation: the length to vertex is equal
What is the value of X in the figure show
Answer:
x=11
Step-by-step explanation:
The equation for the problem is 4x-2=42. The angle (4x-2) is equal to 42 degrees because it is vertical to the angle with 42 degrees. If angles are vertical, they are equal to each other.
Add 2 to both sides of the equation.
4x+2=4x 42+2=44
Simplify.
4x=44
Divide 4 by both sides.
4x/4=x 44/4=11
Simplify to get the final answer.

Explanation:
Draw a horizontal line to cut the figure into a rectangle on top and a triangle down below.
The rectangle has length and width of 6 and 4 (horizontal and vertical components respectively). The area of this rectangle is 6*4 = 24 square units.
The triangle has a base of 6 and a height of 4. The base and height of any triangle are always perpendicular.
The area of the triangle is base*height/2 = 6*4/2 = 24/2 = 12 square units. If you were to cut out half of the triangle and rearrange things, you'll find that a rectangle can be formed. This rectangle is half in area that of the first rectangle we found. This is why we divide by 2 when finding the area of the triangle.
Once you know the two sub-areas, we add them up to get the overall area: 24+12 = 36 square units.

Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a diameter of 10 feet and a height of 8 feet. Container B has a diameter of 12 feet and a height of 7 feet. Container A is full of water and the water is pumped into Container B until Container A is empty.
To the nearest tenth, what is the percent of Container B that is full after the pumping is complete?
Answer:
79.4%
Step-by-step explanation:
the volume of a cylinder is as for any other regular 3D object
base area × height
the base area is for a cylinder a circle.
so, it is
pi×r² × height
the radius (r) is always half of the diameter.
so, volume of cylinder A is
Va = pi×(10/2)² × 8 = pi×25 × 8 = 200pi ft³
the volume of cylinder B is
Vb = pi×(12/2)² × 7 = pi×36 × 7 = 252pi ft³
therefore, in a volume of 252pi ft³ we have 200pi ft³ filled with water.
252pi = 100% filling
1% = 100%/100 = 252pi/100 = 2.52pi
how many % are 200pi ?
as many as times 1% fit into 200pi :
200pi/2.52pi = 200/2.52 = 79.36507937... ≈ 79.4%

A community group sells 2,000 tickets for its raffle. The grand prize is a car. Neil and 9 of his friends buy 10 tickets each. When the winning ticket number is announced, it is found to belong to Neil's group. Given this information, what is the probability that the ticket belongs to Neil?
Answer:
1/10 if its is in the group
Step-by-step explanation:
but if its as the whole thing it would be 1/200 because he has 10 and 10 of 2000 is 1/200
The probability that the winning ticket belongs to Neil is 5%.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
There are a total of 2,000 tickets, and Neil and his 9 friends bought 10 tickets each, so they bought a total of 100 tickets (10 tickets/person x 10 people = 100 tickets).
The probability of Neil's group winning the car is equal to the number of tickets they bought divided by the total number of tickets sold:
Probability = Number of tickets bought by Neil's group / Total number of tickets sold
Probability = 100 / 2000
Probability = 0.05 or 5%
Therefore, the probability that the winning ticket belongs to Neil is 5%.

A card is drawn from a standard deck. Find the probability of drawing a heart or a 7.
=======================================================
Explanation:
There are A = 13 hearts and B = 4 copies of "7"
The count A+B = 13+4 = 17 may seem like it's the count of hearts or "7" cards, but we're double counting the 7 of hearts. So the true count is actually 17-1 = 16
There are 16 cards we want (either a heart or a "7") out of 52 total. Therefore, the probability is 16/52 = (4*4)/(4*13) = 4/13

Answer: Unlock code = 76
==========================================================
Explanation:
Use a factor tree to find the prime factorization of each value
22 = 2*11
30 = 2*3*5
Both values have '2' in common and this is the largest such value. Therefore, the GCF of 22 and 30 is 2.
So E = 2
----------------------------
Since 3 and 8 have no factors in common (other than 1), this means the LCM is 3*8 = 24
We can say that F = 24.
If the numbers had some larger number in common, then we'd have to do a bit more work to find the LCM.
----------------------------
As the hint suggests, we'll use the distributive property to show that
3*(7+10) = G + 30
3*7 + 3*10 = G + 30
21 + 30 = G + 30
21 = G .... subtract 30 from both sides; they cancel and go away
G = 21
----------------------------
Use the same idea for the other equation as well
5*(3 + H) = 15 + 45
5*3 + 5*H = 15 + 45
15 + 5H = 45
5H = 45 ............ subtract 15 from both sides; they go away
H = 45/5 ......... divide both sides by 5
H = 9
------------------------------
The unlock code is
E+F+G+H = 2+24+21+29 = 76
