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.

Just answered the question on edge

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.

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.

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!

Answer:

3/8

Step-by-step explanation:

The 3 groups of 1/8 will be 3/8.

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.

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.

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]

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!

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.
