The proof shows the first five steps for verifying cot^2 (x/2)= cos x+1/cos x-1 The drop-down box to complete the steps of the proof will be the taking square root of the fraction.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between the sides and angles of a right-angle triangle and the trigonometric ratio are defined as the ratio of the pair of a right-angled triangle.
The first five steps for the following proof are,
Taking LHS
[tex]\rm = cot^2 \frac{x}{2}[/tex]
As we know,
cotx=1/tanx
[tex]\rm = \frac{1}{tan^2\frac{x}{2} } \\\\ = \frac{1}{\sqrt{(\frac{1-cosx}{1+cosx})^2 } } \\\\ =\frac{1}{\frac{1-cosx}{1+cosx} }[/tex]
As the left-hand side term is equal to the right-hand side term the proof and its steps are correct.
Thus, the proof shows the first five steps for verifying cot^2 (x/2)= cos x+1/cos x-1 The drop-down box to complete the steps of the proof will be the taking square root of the fraction.

Your brother received two job offers. One offers a regular wage, and the other offers hourly pay. Both are 40-hour-per-week jobs. The wage job includes two weeks of paid vacation, but the hourly job offers only unpaid vacation. The annual salary for the wage job is $35,000. The hourly job pays $17 per hour. Which job pays more?
Answer:
The job with the fixed wage is better and pays more.
Step-by-step explanation:
The annual salary for the fixed wage job is $35,000 and the hourly job is $35,360 because 17x40(no of hours needed to work in a week) x52(no of weeks in a year)
The salary of 2 weeks on the hourly job is $1360 and the paid job offers paid vacation for 2 weeks so $35,360 - $1360 is $34,000 and that is $1000 less than the wage job.

A serval, an African wildcat, leaps high above the ground to pounce on its prey. The height of the serval above the ground in relation to the horizontal distance it travels, both measured in feet, is modeled by the given function.
What does the domain of the function represent in this situation?
A.
the horizontal distance the serval travels during its leap
B.
the height of the serval along the path of its leap
C.
the horizontal distance at which the serval reaches its maximum height above the ground
D.
the maximum height the serval reaches above the ground
Answer:
A. the horizontal distance the serval travels during its leap
Step-by-step explanation:
In this situation, the height along the path that the serval leaps is represented on the y-axis (range value), as against its corresponding horizontal distance on the y-axis (domain value) during the course of its leap.
Therefore, in this situation, the the horizontal distance the serval travels during its leap is the domain of the function.

Tangela bought 12 cans of sodas for $5.40. What was the unit rate for each can of soda?
Answer:
The answer is $0.45.
Step-by-step explanation:
Divide 12 by 5.40 and there's your answer.
12 / 5.40 = 0.45
Rate of per can is $0.45 per
Given that;
Number of cans bought buy Tangela = 12 cans
Total amount paid = $5.40
Find:
Rate of per can
Computation:
Rate of per can = Total amount paid / Number of cans bought buy Tangela
Rate of per can = 5.40 / 12
Rate of per can = $0.45

The sum of the ages of Rudy and his father is 58 years. The difference in their ages is 32 years. How old is each ?
Answer:
Rudy is 13 years old. Her father is 45 years old.
Step-by-step explanation:
It's very simple actually!
All you need to do is subtract 32:
58 - 32 = 26
Then divide:
26 ÷ 2 = 13
13 is Rudy's age. Let's find her father's age!
We then add 32 back to 13:
32 + 13 = 45
And there you have it!

How do I solve for c
Answer:
Uhhh add the top then divide by bottom
Step-by-step explanation:
Bc yes
Answer:
[tex] c = \dfrac{3e + 3d - 5D}{2b} [/tex]
Step-by-step explanation:
[tex] \dfrac{2bc + 5D}{3} = e + d [/tex]
Multiply both sides by 3.
[tex] 2bc + 5D = 3(e + d) [/tex]
[tex] 2bc + 5D = 3e + 3d [/tex]
Subtract 5D from both sides.
[tex] 2bc = 3e + 3d - 5D [/tex]
Divide both sides by 2b.
[tex] c = \dfrac{3e + 3d - 5D}{2b} [/tex]

What is meant by expression?In mathematics, an expression is a sentence that contains at least two numbers or variables and at least one math operation. Addition, subtraction, multiplication, or division are all examples of math operations. An expression, also known as an algebraic expression, is a mathematical statement made up of numbers, variables, and an arithmetic operation between them. For example, 4m + 5 is an expression in which the terms 4m and 5 are separated by the arithmetic sign + and m is the variable of the given expression.Given,
5 (4 + 3) - 3 (3 + 2)
Follow the PEMDAS order of operations
Calculate within parentheses (4 + 3) : 7
