Answer:

  (1/8)(cos(4x) -4cos(2x) +3)

Step-by-step explanation:

Your answer is correct as far as it goes. You now need to use a power-reducing identity on the cos(2x)² term in your answer. The appropriate one is ...

  cos(x)² = (1/2)(1 +cos(2x))

In the context of this problem, using this formula gives you ...

  sin(x)⁴ = (1/4)(1 -2cos(2x) +(1/2)(1 +cos(4x))

  sin(x)⁴ = (1/8)(cos(4x) -4cos(2x) +3)

What is −34, 0.5, 23,−73, 1.2 in order from least to greatest?
denpristay [2]

Answer:

-73, -34, 0.5, 1.2, 23

Step-by-step explanation:

In Mathematics, the set of numbers are arranged in two ways. It means that the numbers can be arranged either in ascending order or descending order. If the numbers are arranged from the least to the greatest, then it is called ascending order. In this form, the numbers are in increasing order. The first number should be lesser than the second number.

If the numbers are arranged from the greatest to the least, then it is called descending order. In this form, the numbers are in decreasing form. The first number should be greater than the second number.

Also, read: Descending Order

Standard Form

<em>The standard form to represent the least to the greatest arrangement </em>of numbers is given by:

a < b < c < d  < …..

Here,  

a, b, c, d represent the numbers

Example: 2 < 5 < 7 < 8

3 = x/12 - 4 what is x
alexgriva [62]

Answer:

x=84

Step-by-step explanation:

Add 4 on both sides

3=x/12-4

7=x/12

Multiply both sides by 12

(12)7=x/12(12)

84=x

Hope this helps! :)
