What are trigonometric identities?

There are three commonly used trigonometric identities.

Sin x = 1/ cosec x

Cos x = 1/ sec x

Tan x = 1/ cot x or sin x / cos x

Cot x = cos x / sin x

We have,

From the figure,

Cosine theorem:

Cos 120° = (4.2² + 5.7² - BC²) / (2 x 4.2 x 5.7)

-0.5 = (17.64 + 32.49 - BC²) / 47.88

-23.94 = 50.13 - BC²

BC² = 50.13 + 23.94

BC = √(74.07)

BC = 8.6

Sine theorem:

BC / Sin ∠A = AC / Sin ∠B

8.6 / Sin ∠A = 4.2 / Sin ∠B

8.6 / 120 = 4.2 / Sin ∠B

Sin ∠B = (4.2 x 120) / 8.6

Sin ∠B = 58.60

∠B = 25.1°

Thus,

The angle is 25.1°.

3. If s varies directly as (r + 1) and s = 8, when r = 3, calculate the value ofr when s = 20.
(4marks)

Answers

Answer:

When s = 20, r = 9

Step-by-step explanation:

Given,

s is directly proportional to (r + 1)

s = k(r + 1)

(k is the constant of proportionality)

When s = 8,

8 = k(3 + 1)

8 = k(4)

8 = 4k

8/4 = k

2 = k

When s = 20,

20 = 2(r + 1)

20 = 2r + 2

20 - 2 = 2r

18 = 2r

18/2 = r

9 = r

A leatherback sea turtles was swimming at 850 below sea level. He went 165 meters and then descendes 165 meters. Draw a number line to show the change in position of the sea turtles from depth it was swimming. What integer represents the sea turtles change in position?

Answers

Answer:

0

Step-by-step explanation:

Initial. Position = (- 850) below sea level

Upward movement = 165m

Deownward movement (descent) = (165m

Change in position : net change

Upward movement + downward movement

(165 + (-165)m = (165 - 165)m = 0

Step-by-step explanation:

. The sum of these is 39, so we can write:

Open the brackets and simplify.

x+x+2+x=+4=39

3x+6=39

You have 37 coins that are nickels, dimes, and pennies. The total value of the coins is $1.55. There are twice as many pennies as dimes. Find the number of each type of coin in the bank.



Answer: Let n be the number of nickel


s, d be the number of dimes, and p be the number of pennies.

Answers

Answer:

n = number of nickels = 7

d = number of dimes = 10

p = number of pennies = 20

Step-by-step explanation:

Let

n = number of nickels

d = number of dimes

p = number of pennies.

n + d + p = 37

0.05n + 0.10d + 0.01p = 1.55

p = 2d

Substitute p = 2d into the equation

n + d + 2d = 37

0.05n + 0.10d + 0.01(2d) = 1.55

n + 3d = 37

0.05n + 0.10d + 0.02d = 1.55

n + 3d = 37 (1)

0.05n + 0.12d = 1.55 (2)

Multiply (1) by 0.05

0.05n + 0.15d = 1.85

0.05n + 0.12p = 1.55

Subtract

0.15d - 0.12d = 1.85 - 1.55

0.03d = 0.3

d = 0.3/0.03

= 10

d = 10

p = 2d

= 2(10)

p = 20

n + d + p = 37

n + 10 + 20 = 37

n + 30 = 37

n = 37 - 30

n = 7

n = number of nickels = 7

d = number of dimes = 10

p = number of pennies = 20

1. Find the distance between the
points: (1, 2),(6, 4)
Someone help me with this plis !​

Answers

Answer:

5.8516

Step-by-step explanation:

To find the distance between these 2 points we have to use the distance formula. The distance formula is as follows:

[tex]d = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]

Let's find the variables of this equation:

x2 = 6

x1 = 1

y2 = 4

y1 = 2

Now, we can plug these in to the equation:

[tex]d = \sqrt{(6-1)^2 + (4-2)^2}[/tex]

Next, let's solve:

[tex]d = \sqrt{(5)^2 + (2)^2}\\d = \sqrt{25 + 4} \\d = \sqrt{29} \\d = 5.8516[/tex]

Therefore, the distance between points (1,2) and (6,4) is 5.8516

Aden spent $10 on a mug and then sold it, making 20% profit, how much did he sell the mug for

Answers

Answer: $2

Step-by-step explanation: 20 percent of 10 is 2

Hope I did this right

The selling cost of the mug is the amount of $12.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

For example, If Misha obtained a score of 57% on her exam, that corresponds to 67 out of 100.

We have been given that Aden spent $10 on a mug and then sold it, making a 20% profit.

The original cost of the mug is $10.

The selling cost of the mug = original cost + 20% of the original cost

The selling cost of the mug = $10 + 20% of $10

The selling cost of the mug = 10 + (20/100)10

The selling cost of the mug = 10 + 0.20 × 10

The selling cost of the mug = 10 + 2

The selling cost of the mug = $12

Therefore, the selling cost of the mug is the amount of $12.

Please reword this paragraph:The mutation I chose was Familial Acromegaly. Familial Acromegaly is caused by an increased amount of growth hormones that are produced during our adulthood and are secreted from our pituitary gland which is located in our brain. Acromegaly is extremely rare to be passed down each generation, when it is, its due to a part of multiple endocrine neoplasia type 1 (MEN1), or a condition called familial isolated pituitary adenoma. Acromegaly is distinguished by enlarged features such as your face, hands, and feet. As the face might change shape due to the excess hormones your jaw may protrude or extend out to a certain point, your nose might get longer, and your lips might get fuller or thicken (basically you might have/get Cardi B-like lips). Familial acromegaly can cause puberty to hit much later, and cause genitalia to possibly be deformed due to the increased growth hormones. It could also cause weakness, vision problems, and heart problems that could eventually lead to heart failure. A carpenter has 183 doorknobs in his workshop.

However, this worry is explained well enough by the cost that indulges to substitute employees who leave the organization and problems that they face while attracting and hiring a new employee. Now, in most of the countries, some employees could not be able to fill out some vacancies which are with higher difficulty is the real sad back in the development of their career. Therefore, in such a scenario, human resource management practices gain vital importance to assist in reducing turnover intentions. (Fabi, Lacoursiere & Raymond, 2015)In previous studies, AMO model (ability, motivation, and opportunity) the human resource practices were studied as in three other dimensions that are, the first bundle of the bundle of practice connected with the skill level of an employee, second bundle of practice was related with the motivation-enhancing and the third one was linked with the extent of opportunity one employee could get to contribute (Jiang, Lepak, Hu & Baer, 2012). Moreover, in this study, these 3 bundles of human resource practices are redefined as one set with the name of high-performance work practices. This research aims to study the impact of three sets of practices at the individual level on the employee intention to leave which explains a high-performance work system at the one side and employee intention to leave on the other side. Previously, researchers didnt aim to study the whole effect of individual human resource practices on the employee quit intentions.The banking sector of Pakistan is consists of thirty-one banks including five representing the public sector and four banks are from abroad, the remaining twenty-two banks are registered as private banks.
