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.

Zack measured a rectangular garden at the park. The longer sides each measured 15 feet and were 3 times longer than the shorter sides. If Zack walked all the way around the garden, how far did he walk?
Given:
The longer sides of a rectangular garden = 15 feet
It were 3 times longer than the shorter sides.
To find:
The total distance covered by Zack if he walked all the way around the garden.
Solution:
Let the shorter side be x.
Longer side = 15 feet
According to given equation, longer side is 3 times longer than the shorter sides.
[tex]15=3x[/tex]
Divide both sides by 3.
[tex]5=x[/tex]
So, the measure of shorter side is 5 feet.
The total distance covered by Zack if he walked all the way around the garden is the perimeter of the garden.
Perimeter of rectangular garden is
[tex]Perimeter=2(length +width)[/tex]
[tex]Perimeter=2(15 +5)[/tex]
[tex]Perimeter=2(20)[/tex]
[tex]Perimeter=40[/tex]
Therefore, the total distance covered by Zack is 40 feet.

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!
Hope this helped! :)

Your bank pays 4% annual interest compounded quarterly on January 1, April 1, July 1, and October 1. You deposited $840 on April 1 and made no other deposits or withdrawals. Find your savings account balance on January 1 of the next year.
and
Your bank pays 4% annual interest compounded quarterly on January 1, April 1, July 1, and October 1. You deposited $840 on April 1 and made no other deposits or withdrawals. How much interest did you earn for these nine months?
Answer:
The interest earned in 9 months is $25.45284
Step-by-step explanation:
The interest rate given by the bank = 4%
The rate at which the interest is applied = Quarterly
The amount of money deposited = $840
The formula for compound interest is given as follows;
[tex]Compound \ interest = P \times \left [ \left(1 + \dfrac{r}{n} \right )^{t \times n} - 1\right ][/tex]
Where;
P = The principal = $840
r = The rate = 4% = 0.04
n = The number of times the interest is compounded per period = quarterly = 4
t = The time duration in period = 9 months = 3/4 × 1 year
Substituting the values gives the Compound interest C.I. as follows;
[tex]C.I. = 840 \times \left [ \left(1 + \dfrac{0.04}{4} \right )^{\dfrac{3}{4} \times 3} - 1\right ] = 840 \times \left [ \left(1 + \dfrac{0.04}{4} \right )^{ 3} - 1\right ] = \$ 25.45284[/tex]
The interest earned in 9 months = $25.45284.

What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
It is also known as the product. If the object n is given to m times then we just simply multiply them.
Given that: 3 groups of 1/8
Then the number 3 and 1/8 is multiplied. Then the expression will be
⇒ 3 × 1/8
⇒ 3 / 8
Then the 3 groups of 1/8 will be 3/8.

What is the equation of the line that passes through the point (1, 7) and has a slope of 2/7?
Answer: y=2/7x+47/7
Step-by-step explanation:
You would use the equation y=mx+b to get the answer. You already know that x=1 and y=7 from the given point and they tell you the slope (m) is 2/7. All you have to do it substitute the values into the equation and solve for b. That would be 7=(2/7)(1)+b. Solving for b gives you 47/7. Therefore, the equation is y=2/7x+47/7. Hope this helps!

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.
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]
