What is triangle?A triangle is a closed two-dimensional geometric shape that is formed by connecting three non-collinear points with straight line segments. Each of these line segments is called a side, and the point where two sides meet is called a vertex. A triangle has three vertices, three sides, and three angles. Triangles can be classified based on the length of their sides and the size of their angles.
Here,
In the right triangle MYK, where MY = 48 units, MK = 73 units, and angle Y = 90 degrees, we can use trigonometric functions to find the length of YK. The trigonometric functions that relate to the sides and angles of a right triangle are:
Sine: sinθ = opposite/hypotenuse
Cosine: cosθ = adjacent/hypotenuse
Tangent: tanθ = opposite/adjacent
To find YK, we need to use the tangent function because we know the opposite and adjacent sides (MY and MK). So, the correct expression to determine YK is: (48)tanK
The other expressions given are:
(73)sinK: This expression would be used to find the opposite side, not YK.
(73)cosK: This expression would be used to find the adjacent side, not YK.
(48)tanM: This expression doesn't relate to the right triangle MYK since there is no angle M in the triangle.

What does an angle mean?
The intersection of the intersecting lines that make up a skew's ends determines both its greatest and smallest walls. Two paths might hypothetically come together at a crossroads. Angle is another outcome of two things interacting. They resemble dihedral shapes the most.

In this diagram, the woman is standing at point A, the flagstaff is at point B, and the top of the flagstaff is at point C. The angle of elevation from the woman to the top of the flagstaff is angle ɑ, and the angle of depression from the woman to the bottom of the flagstaff is angle β. The distance from the woman to the base of the flagstaff is h.
b) The vertical distance from the woman's eye level to the bottom of the flagstaff can be found using trigonometry. We know that the angle of depression from the woman to the bottom of the flagstaff is 20 degrees, so we can use the tangent function to find the vertical distance:
tan(20) = h / 25
h = 25 * tan(20)
h ≈ 9.07 m
Therefore, the vertical distance from the woman's eye level to the bottom of the flagstaff is approximately 9.07 meters.
c) To find the height of the flagstaff, we can use the tangent function again, this time with the angle of elevation from the woman to the top of the flagstaff:
tan(76) = (h + x) / 25
where x is the height of the flagstaff above the bottom
We know that h is approximately 9.07 m from part b. Rearranging the equation, we get:
x = 25 * tan(76) - h
x ≈ 24.52 m - 9.07 m
x ≈ 15.45 m
Therefore, the height of the flagstaff is approximately 15.45 meters.

The area of a parallelogram is represented by 3x² + 15x-2xy-10y.
Write this expression in factored form.
the factored form of the expression 3x² + 15x - 2xy - 10y is (x + 5)(3x - 2y).
How to solve the expression?
To factor the expression 3x² + 15x - 2xy - 10y, we need to look for common factors and grouping of terms. First, we can factor out 3x from the first two terms and -2y from the last two terms:
3x(x + 5) - 2y(5 + x)
Now we can see that both terms have a common factor of (x + 5), so we can factor it out:
(x + 5)(3x - 2y)
Therefore, the factored form of the expression 3x² + 15x - 2xy - 10y is (x + 5)(3x - 2y).
This expression represents the area of a parallelogram with base x+5 and height 3x-2y. The factored form makes it easier to see the relationship between the dimensions of the parallelogram and the expression for its area. For example, we can see that the area is zero when either factor is zero, meaning that the base or height of the parallelogram is zero. We can also use the factored form to find the dimensions of a parallelogram given its area.

the equation Y = 1(1-x)² - 5 represents a downward-facing parabola with vertex at (1,-5), which opens upwards, and the value of Y increases as x moves away from 1 in either direction.
What is equation?
An equation is a mathematical statement that contains an equality sign (=) between two expressions. It indicates that the expressions on either side of the equality sign are equal in value. Equations can have variables, constants, coefficients, and operators like addition, subtraction, multiplication, and division. The variables represent unknown values, and the goal of solving an equation is to determine the value(s) of the variable(s) that make the equation true.
For example, the equation 2x + 5 = 11 is an algebraic equation, where "x" is the variable, "2" and "5" are constants, and "+" and "=" are operators. The solution to this equation is x = 3, since when we substitute x = 3 into the left-hand side of the equation, we get 2(3) + 5 = 11, which satisfies the equality.
The equation given is Y = 1(1-x)² - 5.
This equation represents a parabola in vertex form, where the vertex is at (1,-5). The coefficient of the squared term is positive, which means that the parabola opens upwards.
When x = 1, the value of Y is -5, which is the minimum value of the parabola. As x moves away from 1 in either direction, the value of the expression (1-x)² increases, causing the value of Y to increase as well.
Therefore, the graph of this equation is a downward facing parabola with the vertex at (1,-5), and it opens upward. As x moves away from 1, the value of Y increases.
In summary, the equation Y = 1(1-x)² - 5 represents a downward-facing parabola with vertex at (1,-5), which opens upwards, and the value of Y increases as x moves away from 1 in either direction.

Does the relation represent a function? Explain.
No, because for each input there is not exactly one output
No, because for each output there is not exactly one input
Yes, because for each input there is exactly one output
Yes, because for each output there is exactly one input
Correct option is A, It is not function, because for each input there is not exactly one output.
A function is a relation between a set of inputs (the domain) and a set of possible outputs (the range), where each input is associated with exactly one output. In other words, a function is a set of ordered pairs (x, y) such that no two ordered pairs have the same first element (x-value) and different second elements (y-value).
A function can be represented in different ways, including as a table of values, as a graph, or using a formula or rule. For example, the function f(x) = 2x + 1 represents a rule where each input value x is multiplied by 2 and then 1 is added to the result to obtain the output value f(x).
Functions are important in mathematics and in many fields such as physics, engineering, and economics, where they are used to model and analyze various phenomena.
To determine whether the relation represents a function, we need to check whether for each input (x-value), there is exactly one output (y-value).
Looking at the given points, we can see that the x-values 3/4 and 3 both have more than one corresponding y-value (-2 and -1/2, respectively). Therefore, the relation does not represent a function because for each input there is not exactly one output.

The company has received 14 entries in the sweepstakes, and they know that the probability of receiving a magazine subscription order with an entry form is 0.5. Now, we want to find the probability that less than 10 of the entry forms will include an order.
To find the probability that less than 10 of the entry forms will include an order, we need to add up the probabilities of getting 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9 orders. We can use the binomial probability formula to calculate these probabilities:
P(X = x) = (n choose x) x pˣ x (1 - p)ⁿ⁻ˣ
where P(X = x) is the probability of getting x successes, n is the number of trials, p is the probability of success, and (n choose x) is the number of ways to choose x successes from n trials.
We can also use a calculator or spreadsheet to do the calculations.
P(X = 10) = (14 choose 10) x p¹⁰ * (1 - p)¹⁴⁻¹⁰ = 0.0193

The product of two number is 17,20,740, When one number is 1785 and other number is 39,460.
To find the other number, we can divide the product of the two numbers by the known number:
Other number = 17,20,740 ÷ 1785
We can simplify this calculation by factoring out common factors from both numbers. First, we can factor 1785 into its prime factors:
1785 = 3 x 3 x 5 x 7 x 2
Next, we can factor 17,20,740:
17,20,740 = 2^2 x 5 x 7 x 11 x 13 x 17 x 19
We can then cancel out any common factors in the numerator and denominator. In this case, we can cancel out one factor of 5, one factor of 7, and two factors of 2:
Other number = (2 x 11 x 13 x 17 x 19) ÷ (3 x 3 x 5 x 7 x 2)
Simplifying this expression further, we get:
Other number = (2 x 11 x 13 x 17 x 19) ÷ (3^2 x 5 x 7)

What is a fraction?
A fraction is a mathematical term that represents a part of a whole or a ratio between two quantities.
To solve this problem, we need to follow the steps given in the question.
Step 1: Increase the number 15/16 by 3/5 of it.
We can write this mathematically as:
15/16 + (3/5)*(15/16)
Multiplying 15/16 by 3/5, we get:
(15/16)*(3/5) = 45/80
Adding this to 15/16, we get:
15/16 + 45/80 = 375/320 + 225/320 = 600/320
Simplifying this fraction, we get:
600/320 = 75/40 = 15/8
So, the result of the first step is 15/8.
Step 2: Increase the resulting number by 3/5 of it.
We can write this mathematically as:
(15/8) + (3/5)*(15/8)
Multiplying 15/8 by 3/5, we get:
(15/8)*(3/5) = 45/40
Adding this to 15/8, we get:
15/8 + 45/40 = 300/160 + 45/160 = 345/160

The marked price of a merchandise is 20% higher than the cost price. After the merchandise is sold at 90% of the marked price, there is still a profit of RM 24. Find the cost price of the merchandise.
Answer:
RM 300
Step-by-step explanation:
Let's assume that the cost price of the merchandise is "C" in RM.
According to the problem, the marked price of the merchandise is 20% higher than the cost price. Therefore, the marked price can be calculated as:
Marked price = Cost price + 20% of Cost price
Marked price = C + 0.2C
Marked price = 1.2C
The merchandise is sold at 90% of the marked price, which means the selling price can be calculated as:
Selling price = 90% of Marked price
Selling price = 0.9 × 1.2C
Selling price = 1.08C
We are given that the profit after selling the merchandise is RM 24. Profit is calculated as the difference between selling price and cost price. Therefore, we can write:
Profit = Selling price - Cost price
24 = 1.08C - C
24 = 0.08C
Solving for C, we get:
C = 24/0.08
C = 300
Therefore, the cost price of the merchandise is RM 300.

The workshop would need to be cleaned in 4 hours 21 workers.
How does division work?
In mathematics, division is the process of dividing a quantity into equal pieces or groups. It is used to determine how many times one number can be divided by another number because it is the inverse of multiplication.
In light of the facts provided, we can apply the following formula to determine how long a task will take to complete:
Work = Time / (rate)
Cleaning the workshop is the continual work in this situation. The rate is the amount of work completed in a given length of time. Assume that all employees work at the same rate, making the rate proportionate to the workforce.
Hence, the rate of work is: if 24 people can clean the workshop in 3.5 hours.
rate=(work)/(time)=(1 workshop)/(3.5 hours * 24 workers)=1/84 workshop per worker per hour
We now need to calculate how long it would take 10 employees to clean the workshop. Let's apply the formula once more:
Time = Work / Rate = (1 Workshop) / (10 Workers * Rate)
Using the earlier rate as a substitute, we obtain:
As a result, cleaning the workshop would require 21 people 4 hours.
