What is an example of ordered pair function?
An ordered pair function is a type of mathematical function that associates certain pairs of elements (called ordered pairs) with a single output. For example, the function f(x,y) = x+y associates the ordered pair (2,3) with the output 5.
What is function?A function is a block of organized, reusable code that is used to perform a single, related action. Functions provide better modularity for your application and a high degree of code reusing. As you already know, Python gives you many built-in functions such as print(), etc. but you can also create your own functions. These functions are called user-defined functions.
This is because 2+3 = 5. Another example is the function f(x,y) = x×y,
which associates the ordered pair (3,4) with the output 12, since 3×4 = 12.

In the triangle below, with right angle R, suppose that m is Angle Q=(5x-13) and m is Angle S=(4x-5) Find the degree measure of each angle in the triangle.
Answer:
Degree measure of each angle is 90⁰, 47⁰ and 43⁰
Step-by-step explanation:
since the triangle is right angled, we assume that Q and S are the other angles of this triangle R
Thus using the concept that angles inside a triangle add up to 180⁰ and we already have one angle as 90⁰( since the triangle is right angled). we therefore know that Q + S = 90⁰
5x - 13 + 4x - 5 = 90⁰
9x = 108
x = 12
We now replace x in Q and S to get the angles
Q = 5(12) -13
= 47⁰
S = 4(12) - 5
= 43⁰
2. Lyda is taking a test worth 50 points. Her goal is to score 80%.
Write a proportion to figure out how many points she needs to accomplish her goal.
Answer: Lyda wants to score 80% on a test that is worth 50 points. To figure out how many points she needs to accomplish her goal, we can set up a proportion using her desired percentage as the proportion of points she wants to score over the total number of points on the test.
score / total points = percentage / 100
To figure out the number of points Lyda needs to score, we can use the proportion above and cross-multiply:
score * 100 = percentage * total points
We know that percentage=80 and total points =50, so we can substitute these values:
score * 100 = 80 * 50
score = (80*50) / 100 = 40
So Lyda needs to score 40 points to accomplish her goal of 80%.
The proportion would be score / total points = x/100 = percentage/100 = 40/50 = 8/10
It's worth to mention that scoring 80% on a test means she scored 40 points on a test worth 50, the minimum score to pass is 30 so she got a good grade already.

On solving the provided question we can say that - the probability of the event will be there are two red sides, thus multiplying 16.6667 by two results in 33.3333%.
What is probability?A branch of mathematics known as probability measures the possibility of an event happening or a proposition being true. The probability of an occurrence is a number between 0 and 1, where roughly 0 denotes the event's improbability and 1 denotes certainty. A probability is a numerical representation of the possibility or probability that a specific event will take place. Probabilities can alternatively be stated as percentages ranging from 0% to 100%, or as percentages from 0 to 1. the proportion between the number of events in a comprehensive collection of equally likely outcomes that lead to a certain occurrence and the entire number of outcomes.
Each side would be 50%, and if one side were divided among three people, it would equal 16.6667 per person.

Isosceles Triangle has 50°, 65°, 65°
An isosceles triangle is a triangle that has two sides of equal length. The two equal sides are called the legs and the third side is called the base of the triangle.
Properties of Isosceles Triangle:
The two equal sides of an isosceles triangle are known as ‘legs’, and the angle between them is called the vertex angle or apex angle.In an isosceles triangle, if two sides are equal, then the angles opposite to the two sides correspond to each other and are also always equal.The isosceles triangle has three acute angles, meaning that the angles are less than 90°.The sum of three angles of an isosceles triangle is always 180°. The side opposite the vertex angle is called the base and the base angles are equal, and perpendicular to the apex angle bisecting the base and the apex angle.To know more about Isosceles Triangle:

Answer:
Option D. {7 + i√71 / 20, 7 – i√71 / 20}
Step-by-step explanation:
10m² – 7m + 3 = 0
Using formula method, the solution to equation can be obtained as follow:
10m² – 7m + 3 = 0
Coefficient of m² (a) = 10
Coefficient of –7m (b) = –7
Constant (c) = 3
m = –b ±√(b² – 4ac) / 2a
= – –7 ±√((–7)² – 4 × 10 × 3) / 2 × 10
= 7 ±√(49 – 120) / 20
= 7 ±√(–71) / 20
Recall:
–17 = –1 × 17
Thus,
7 ±√(–71) / 20 = 7 ±√(–1 × 71) / 20
Recall:
√–1 = i
Thus,
7 ±√(–1 × 71) / 20 = 7 ± i√71 / 20
= 7 + i√71 / 20 or 7 – i√71 / 20
Therefore, the solutions to the equation are:
{7 + i√71 / 20, 7 – i√71 / 20}

Jack split 25 jellybeans between his brother and himself so that his brother has one more than twice the number Jack has. How many jellybeans does each have?
Answer:
Jack has 8 jellybeans and his brother has 17 jellybeans
Step-by-step explanation:
Jack+Jack's Brother= total
x+(2x+1)=25
3x+1=25
3x=24
x=8
2*8+1=16+1=17
Jack has 8 jellybeans and his brother has 17 jellybeans.
What is an equation?"It is a statement which consists of equal symbol between two mathematical expressions."
What is system of equations?"It is a finite set of equations for which we find a common solution."
For given example,
Let Jack has 'x' jellybeans and his brother has 'y' jellybeans.
Jack split 25 jellybeans between his brother and himself.
⇒ x + y =25 ...........................(1)
his brother has one more jellybean than twice the number Jack has.
⇒ y = 2x + 1 ...........................(2)
So, we get system of equations,
x + y =25
y = 2x + 1
Now, substitute the value of y [from equation (2)] in the equation (1),
⇒ x + (2x + 1) = 25
⇒ 3x + 1 = 25
⇒ 3x = 24
⇒ x = 8
Substitute this value of 'x' in the equation (2),
⇒ y = 2(8) + 1
⇒ y = 17
Therefore Jack has 8 jellybeans and his brother has 17 jellybeans.

Geoff purchased an annual golf pass for a municipal golf course in his town. He pays a flat fee for the annual golf pass and then each round he plays he must pay the additional cost for a golf cart. A linear model of this situation contains the values (25 , 1,167) and (41 , 1,407), where x represents the number of times he plays each year, and y equals the total amount he spends on golf in one year. What is the flat fee for the annual golf pass? A. $15 B. $1,032 C. $792 D. $807
To find the flat fee for the annual golf pass, we need to find the y-intercept of the linear model. The y-intercept is the point at which the line crosses the y-axis, which in this case represents the flat fee for the annual golf pass.
The equation of a line in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept.
We can find the slope of the line using the two points given: (25, 1,167) and (41, 1,407). The slope is (1,407 - 1,167) / (41 - 25) = 240 / 16 = 15.
Now that we know the slope, we can use either of the two points given to find the y-intercept. Let's use the point (25, 1,167). Plugging the values into the equation y = mx + b, we get 1,167 = 15 * 25 + b. Solving for b, we find that b = 1,167 - 15 * 25 = -300.
The y-intercept is -300, so the flat fee for the annual golf pass is $300. The correct answer is therefore D, $807.

Mr. Pratt was building a house. A ladder that is 10 ft. long is leaning against the side of a building. If the angle formed between the ladder and the ground is 65 degrees, how far is the bottom of the ladder from the base of the building? Round to one decimal place.
Answer:
[tex]\huge\boxed{\text{4.2 feet}}[/tex]
Step-by-step explanation:
In order to solve this problem, we can use the basic trigonometric functions.
Let's first start to break down the triangle scenario we're given.
We know that the ladder is 10 ft tall. Given that it is slanted, it's likely the hypotenuse.We know the angle formed between the ladder and the ground is 65°. Since the ladder will form a 90° angle with the ground, the last angle will have to follow the triangle rule.The triangle rule is that all angles within a triangle will add up to 180°. Using this logic, we can find the measure of the third angle from the other two[tex]90+65+x=180[/tex], [tex]155+x=180[/tex], [tex]x=25[/tex]Now we know the three angles of the triangle and one side.
We can find the other two sides (or just the base side, in our case), using trigonometric functions such as sin, cos, and tan. We can substitute in their formulas and find lengths based on angle measures.
We know using SOH CAH TOA the relationships between opposites, adjacents, and hypotenuses with these functions. SOH CAH TOA states that:
Sin = Opposite/HypotenuseCosine = Adjacent/HypotenuseTangent = Opposite/AdjacentUsing the triangle, we want to find a relationship that has the base we need as an opposite/adjacent that can use the hypotenuse (since it's the only side length we know.
Well, we can take the sin of the 25 degree angle - it's opposite is the base leg and the hypotenuse is 10.
We can then represent this using an equation:
[tex]\text{sin}(25) = \frac{\text{opposite}}{\text{hypotenuse}}[/tex] [tex]\text{sin}(25) = \frac{\text{opposite}}{10}[/tex] (Since we know the hypotenuse is 10)[tex]\text{sin}(25) \cdot 10 = \text{opposite}[/tex] We know that sin(25) is roughly 0.4226 because of our. calculator. We can then multiply that by 10 to recieve 4.226. This rounds to 4.2 (to the nearest 10th).Therefore, the length of the base leg is 4.2 feet

For the initial 90 miles of a flight, the pilot heads 8° off course in order to avoid a storm. The pilot then changes direction to head toward the destination for the remainder of the flight, making a 157° angle to the first flight course. Determine the total distance of the flight
A. 48.4
B. 135.9
C. 138.4
D. 228.4
In the above scenario, note that the total distance of the flight is given as: 48.4 miles (approximately). This is solved using the law of Sines to find x.
What is the law of Sines?The connection between the sides and angles of non-right (oblique) triangles is defined by the Law of Sines. Simply put, it asserts that the ratio of the length of a triangle's side to the sine of the angle opposite that side is the same for all triangle sides and angles.
Thus, with regard to the problem modeled in the attached triangle, because two angles are given, the missing angle is 180° − (157° + 8°) or 15°. Use the Law of Sines to find x.
Using the law of ins we can state that:
Sin 8°/x = sin 15°/90
90 (Sin 8°) /x = Sin 15°
90 Sin 8° = x Sin 15°
90 Sin 8° / Sin 15° = x
90 (0.13917310096)/ 0.2588190451 = x
