Please Help!!! Trigonometry Is So Complicated To Me

Answers

Answer 1

Answer:

x = 4

Step-by-step explanation:

Given that sin(13x) = cos(9x+2)

Since sintheta  = cos(90 - theta)

hence sin (13x) = cos (90 -13x)

Substitute into the original equation

cos (90 -13x) = cos(9x+2)

90-13x = 9x+2

-13x - 9x = 2 - 90

-22x = -88

x = 88/22

x = 4

Hence the value of x is 4

f(x) = 4 - x^2 and g(x) = 2 - x

(f - g)(x) = 4 -x^2 - (2-x)

             =  4 -x^2 - 2+x

if there consecutive terms of an AP are k+2 ,4k -6 and 3k-2 . What is the value of k​

Answers

Answer:   k = 3

===========================================================

Explanation:

A = first term = k+2B = second term = 4k-6C = third term = 3k-2

To go from the first term to the second term, we add on some common difference d.

So,

B = A+d

B = (k+2)+d

4k-6 = k+2+d

4k-6-k-2 = d

d = 3k-8

---------------

Similarly, to go from the second term to the third term, we also add on d

C = B+d

C = (4k-6)+d

C = (4k-6)+(3k-8)

C = 7k-14

3k-2 = 7k-14

---------------

Let's solve for k

3k-2 = 7k-14

-2+14 = 7k-3k

12 = 4k

4k = 12

k = 12/4

k = 3  is the final answer

---------------

If k = 3, then we have these three terms:

A = k+2 = 3+2 = 5B = 4k-6 = 4(3)-6 = 6C = 3k-2 = 3(3)-2 = 7

The arithmetic progression (AP) is 5, 6, 7. The common difference is d = 1.

Note how d = 3k-8 = 3(3)-8 = 1

A rectangular in ground pool needs to be filled with water. The pool is 20 feet long 9 1/2 feet wide, and 5 1/2 feet deep determin the maximum amount of water the pool can hold? PLS ANSWER IM GOING TO FAIL

Answers

Answer:

1045 ft³ of water

Step-by-step explanation:

Given :

Length = 20 feets

Width = 9 1/2 feets

Height = 5 1/2 feets

The maximum of water the pool can hold is equivalent to the volume of the pool ;

Hence, Volume = Length * width * height

Volume = 20 * 9 1/2 * 5 1/2

Volume = 1045 ft³ of water

4x-3+2x-7+5x-1=58

What is x?

Answers

Answer:

69/11

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4x−3+2x−7+5x−1=58

4x+−3+2x+−7+5x+−1=58

(4x+2x+5x)+(−3+−7+−1)=58(Combine Like Terms)

11x+−11=58

11x−11=58

Step 2: Add 11 to both sides.

11x−11+11=58+11

11x=69

Step 3: Divide both sides by 11.

11x /11  = 69/11

Answer:

x = 69/11

Step-by-step explanation:

4x - 3 + 2x - 7 + 5x - 1 = 58 collect like terms ↓

11x - 3 - 7 - 1 = 58

11x - 11 = 58 move the constant to the right-hand side and change its sign ↓

11x = 58 + 11 add the numbers ↓

11x = 69 then divide both sides of the equation by 11 ↓

x = 69/11 ;)

Answers

Answer:

The number of smoking rooms [tex]N_s = \frac{480(100-x)}{100}[/tex], in which x is the percentage of non-smoking rooms.

Step-by-step explanation:

We are given a percentage of rooms that are non smoking, lets say x%, and (100-x)% will be smoking rooms. The number of rooms which are smoking is the total number of 480, multiplied by (100-x) and divided by 100.
