Csc(6x)-cot(6x)/csc(6x)+cot(6x)

Answers

Answer 1

The value of the expression Csc(6x)-cot(6x)/csc(6x)+cot(6x) is tan²3x.

What is a Trigonometric Ratios?

Trigonometric Ratios are ratios of the side of a right angled triangle. These are used to find the missing sides and angles of a right angled triangle.

[tex]\rm =\dfrac {cosine(6x)-cot(6x)}{cosine(6x)+cot(6x)}\\\\\\\ = \dfrac{ \dfrac{1}{sin6x} - \dfrac{cos6x}{sin6x}}{ \dfrac{1}{sin6x} + \dfrac{cos6x}{sin6x}}\\\\\\ = \dfrac{ 1-cos 6x}{1+cos6x}[/tex]

( 1- cosx = 2sin²x/2) ( 1+cosx = 2cos²x/2)

[tex]\rm = \dfrac{ 2 sin^2 3x}{2 cos^2 3x}\\\\\\\\=tan^2 3x[/tex]

Answers

Answer:

1. k=-9

2. a=-12

Step-by-step explanation:

1. -12(k+4)=60

use distributive property

-12k-48=60

add 48 to both sides

-12k=108

divide both sides by -12

k=-9

2. 8(3a)=9(2a-4)

use distributive property

24a=18a-36

subtract 18a on both sides

6a=-36

divide both sides by 6

a=-12

Blank two the options are: one-seventh, one-twelfth, three twenty-sixths, or thirty-six thirds

Blank three the options are one, eighty-four, seven twelfths, or twenty-one twenty-sixths

Please help me with the problem.

Answers

List all the info:

3/8 gallon of white paint

2 7/8 gallon of blue paint

11/4 gallon of red paint

First, let’s answer the first question.

Francis has made _____ gal of paint when he first mixes the three colors.

Add all the gallons of paints together and you get 6. So, Francis has made 6 gal of paint when he first mixes the three colors.

Now for the second blank. All you have to do is do 6 divided by 3/8 which is 16. So, The constant of proportionality of white paint to gallons of mixed paint is 16.

Lastly, you will have to do is 3/8 x 7 = 2 5/8. (Im not too sure about this part though, but the rest I‘m pretty confident about)

Vladimir is looking to retire in 10 years. He has a plan to put $25,000 into an investment today that earns interest at a fixed amount per year. What would be a reasonable domain and range for a function modeling the total amount of the investment, including interest?
25 Points for the correct answer

Answers

The domain and range for a function modeling the total amount of the investment, including interest are as follows;

Domain, X = {0<= years <= 10}Range, Y (total amount) = {$25,000<= Y <= 25,000( 1 + 10R)}

The starting principal amount, P is $25,000.

Let the interest rate per year, be represented as, R (%)

Time of investment, T = 10 years

In essence, after 10 years, the total amount Vladimir has is;

Total amount = 25,000( 1 + xR).

In essence, the domain (No. of years ) is;

Domain, X = {0<= years <= 10}

Range, Y (total amount) = {$25,000<= Y <= 25,000( 1 + xR)}

Equation: y = -1x + 4

Step-by-step explanation:

In order to create an equation, you need to put it in slope-intercept form ( y = mx + b ). The best way to figure out to create your equation is to graph the points. 'Y' means the y-axis. 'mx' refers to the slope of a particular line and b is concluding where the line crosses the y-axis.

Step-by-step explanation: TOOK THE FOR K12 HOPE THIS HELPS

The difference of the given expression is 3/20 x - 3.

Given that, (2/5x−1)−(1/4x+2).

What is the subtraction of expressions?

To subtract an algebraic expression from another, we should change the signs (from '+' to '-' or from '-' to '+') of all the terms of the expression which is to be subtracted and then the two expressions are added.

Now, (2/5x−1)−(1/4x+2)

= (2/5 x - 1/4 x) -1 - 2

= (8/20 x - 5/20 x) - 3

= 3/20 x - 3

Therefore, the difference of the given expression is 3/20 x - 3.

Answers

The possible length of the rectangular field as represented by an inequality is; l ⩾ 322 centimetres

The perimeter of a rectangular field is;.

Perimeter = (2 × length) + (2 × width)

However; the perimeter of the field is at least 684 centimetres.

Therefore;

[tex]perimeter \geqslant 684cm[/tex]

Therefore;

2l + 40 ⩾ 684

2l ⩾ 644

l ⩾ 644/2
