C_a = pi * d_a

C_a = pi*20

C_b = pi * d_b

Trigonometric functions have some interesting symmetry properties

If tan x= -2.5, then tan (-x)= 2.5 and If sin x= 0.4 then sin (-x)= -0.4

If cos x = 0.9 then cos (-x)= 0.9  If tan x = 1.5 then tan (pi+x)= -1.5

Trigonometric functions are mathematical functions that are widely used in various fields, including mathematics, physics, and engineering. The most commonly used trigonometric functions are sine, cosine, and tangent, which are abbreviated as sin, cos, and tan, respectively.

Trigonometric functions have some interesting symmetry properties. For example, the sine and tangent functions are odd functions, which means that sin(-x) = -sin(x) and tan(-x) = -tan(x). On the other hand, the cosine function is an even function, which means that cos(-x) = cos(x).

These symmetry properties have important implications in many applications of trigonometric functions. For example, if we know the value of sin(x), we can immediately determine the value of sin(-x) by using the odd symmetry property. Similarly, if we know the value of cos(x), we can determine the value of cos(-x) by using the even symmetry property.

(d) The probability that the first is for medical assistance and the second is not for medical assistance = 0.2331

(e) The probability that exactly one of the next two calls is going to be for medical assistance = 0.4662

The probability of an event is the proportion of favourable outcomes to all other possible outcomes. The symbol x can be used to denote how many successful outcomes there were in an experiment with 'n' outcomes. The formula below can be used to determine a given event's probability:

Probability (Event) = Positive Results/Total Results

                                 = x/n

Given P (call for medical assistance) = 0.63

This means that out of all incoming calls to the fire station, the probability that the call is for medical assistance is 0.63 or 63%. The complement of this event, which is the probability that an incoming call is NOT for medical assistance, is:

P (Not Medical Assistance) = 1 - P (Medical Assistance)

                                            = 1 - 0.63

                                            = 0.37

Now, assuming that successive calls are independent of one another, the probability that two successive calls will both be for medical assistance will be:

P (2 calls for medical assistance)

= 0.63 × 0.63

= 0.3969

The probability that the first is for medical assistance and the second is not for medical assistance will be:

P (1st for medical assistance × 2nd for not medical assistance)

= 0.63 × 0.37

= 0.2331

The probability that exactly one of the next two calls is going to be for medical assistance will be:

P (Exactly 1 call for medical assistance)

= (0.63×0.37) + (0.63×0.37)

= 0.2331 + 0.2331

Therefore, a function equivalent to y = x² - 8x + 10 is: y = (x - 4)² + 4.

In mathematics, a function is a relation between a set of inputs (called the domain) and a set of possible outputs (called the range), with the property that each input is associated with exactly one output. Functions are often denoted using function notation, such as f(x) or g(y), where the letter in parentheses represents the input and the expression to the right of the parentheses represents the output. Functions are used in many areas of mathematics, science, and engineering to model real-world phenomena and to solve problems. They are essential tools for analyzing data, making predictions, and creating mathematical models of physical and natural systems.

Here,

The function y = x² - 8x + 10 is a quadratic function, which has a U-shaped graph. To find a function that is equivalent to this function, we can start by completing the square, which involves adding and subtracting a constant term to create a perfect square trinomial. We can then write the function in vertex form, which is y = a(x - h)² + k, where (h, k) is the vertex of the parabola.

Completing the square, we get:

y = x² - 8x + 10

= (x² - 8x + 16) - 6 + 10 // Add and subtract (8/2)² = 16 to create a perfect square

= (x - 4)² + 4

Now we can see that the vertex of the parabola is at (4, 4). We also see that the coefficient of the squared term is 1, which means the parabola opens upward.

The area of the blue-shaded region is 19.95 m²

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.

Given that, a rectangle with length 14 m, and diagonal 15.5 m, a parallelogram has been cut out of it, we need to find the area remaining,

Using the Pythagoras theorem,

15.5² = 14²+w² [width]

w² = 240.25-196

w² = 44.25

w = 6.65

Therefore, the width of the rectangle is 6.65 m

That mean, the height of the parallelogram is 6.65 m,

The area of the blue-shaded region, is calculated by subtracting the area of the parallelogram by the area of the rectangle,

Area of the remaining region = 14×6.65-11×6.65

= 6.65(14-11) = 6.65×3

= 19.95 m²

Answer:

Step-by-step explanation:

Let's begin by calculating Jim's total cost for creating one painting:

Cost of paint and canvas + Cost of brushes = $44 + $1 = $45

This means that Jim makes a profit of $45 - $45 = $0 per painting sold until he breaks even.

To determine how many paintings Jim needs to sell to break even, we can set up an equation:

Total Cost = Total Revenue

Let's say Jim sells x paintings. Then his total revenue would be:

Total Revenue = $45x

His total cost would be the cost of materials plus the cost of brushes multiplied by the number of paintings:

Total Cost = $45 + $1)x = $46x

Setting these equal, we get:

$46x = $45x

Solving for x, we get:

x = 45

So Jim needs to sell 45 paintings to break even.

Once he has sold 45 paintings, he will have earned:

Total Revenue = $45 x 45 = $2025

So Jim will have earned $2025 after selling 45 paintings.

Answer:

Step-by-step explanation:

To break even, Jim's total revenue from selling his paintings should be equal to his total cost of producing them, including the cost of materials and the cost of the brushes. Let's call the number of paintings he needs to sell to break even as "x".

The cost of producing each painting is $44 + $1 = $45.

The revenue from selling each painting is $45.

So, Jim's total revenue from selling x paintings would be:

Total revenue = Price per painting x Number of paintings sold

Total revenue = $45 x x

Total revenue = $45x

Jim's total cost of producing x paintings would be:

Total cost = Cost per painting x Number of paintings produced + Cost of brushes

Total cost = $45 x x + $1

Total cost = $45x + $1

For Jim to break even, his total revenue must equal his total cost:

Total revenue = Total cost

$45x = $45x + $1

Solving for x:

$45x - $45x = $1

0 = $1

This is a contradiction, meaning that the situation is impossible. It is impossible for Jim to break even by selling his paintings at the given prices. If he sells each painting at $45, which is the same price he paid to produce it, he will not make any profit. In fact, he will lose $1 for every painting he sells due to the cost of the brushes.

If Jim wants to break even or make a profit, he will need to increase the selling price of his paintings or find ways to reduce the cost of producing them.

After 2.5 years the price of land and the price of house will be equal.

A quick and easy method of calculating the interest charge on a loan is called a Simple interest.

Given that;

A person purchases a piece of land in Rs.80, 00,000 in 2075 B.S.

And, At the same time of 2075 B.S. a house is constructed on a piece of land in Rs. 2,70,00,000.

Since, The price of land increases at the rate of 20% per annum.

Hence, We get;

A = 80,00,000 (1 + 20/100)ⁿ

And, The price of house depreciates at the rate 20% per annum.

Hence, We get;

A = 2,70,00,000 (1 - 20/100)ⁿ

Let after n years the price of land and the price of house will be equal.

Thus, We get;

80,00,000 (1 + 20/100)ⁿ =  2,70,00,000 (1 - 20/100)ⁿ

8 (120/100)ⁿ = 27 (80/100)ⁿ

8 (6/5)ⁿ = 27 (4/5)ⁿ

Take log both side,

log 8 + n (log 6 - log 5) = log 27 + n (log 4 - log 5)

0.9 + n × 0.8 = 1.4 + n × 0.6

0.9 + 0.8n = 1.4 + 0.6n

0.2n = 0.5

n = 2.5 years

The diagonal distance from the airplane to the runway is approximately 5230.8 ft.

Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles. It is used to solve problems related to measurements of angles and distances.

The angle of depression of 18° is the angle between the airplane's line of sight and the horizontal line representing the runway. We can label the altitude of the airplane as 1560 ft:

Now we can use trigonometry to find the diagonal distance from the airplane to the runway. In particular, we can use the tangent function:

tan(18°) = opposite / adjacent

In this case, the opposite side is the altitude of the airplane (1560 ft), and the adjacent side is the diagonal distance we're trying to find (x). Therefore:

tan(18°) = 1560 / x

To solve for x, we can multiply both sides by x and then divide both sides by tan(18°):

x = 1560 / tan(18°)

Using a calculator, we find that:

x ≈ 5230.8 ft

Therefore, the diagonal distance from the airplane to the runway is approximately 5230.8 ft.
