The solution to 1 - cos(6x) is 2sin²(x).
Hence, option B) 2sin²(x) is the correct answer.
<h3>What is solution to 1 - cos(6x)?</h3>
Given that; 1 - cos(6x) = ?
First, we rewrite using trig identity
1 - cos(2 × 3x)
Using the double angle identity, { <em>cos2(x) = 1 - 2sin²(x)</em> }
1 - ( 1 - 2sin²(x) )
Eliminate the parentheses
1 - 1 + 2sin²(x)
2sin²(x)
The solution to 1 - cos(6x) is 2sin²(x).
Hence, option B) 2sin²(x) is the correct answer.

Based on the understanding of the underlying statistics editor's has been right about the droughts there a major drought because if you take average rainfall was 30 and one of the year it was 18 the normal distribution or bar graphs falls from 30 to 18. If you take standard deviation minimum rainfall is 22 and minimum rainfall is 10 which is drastically low.Editors is right there is decline in rainfall which could lead to droughts,
Step-by-step explanation:
- Normal distribution, basically a bell shaped curved which has two sides.
- Two sides which is a histogram which is used.
- example plane it takes of from one height goes to maximum.
- example plane landing from height to landing.
- Average is middle value of the data which gives a number of entire lot.
- Standard deviation is squaring error and error which is plus or minus.
- Statistics descriptive statistics are based on averaging and then normal.
Answer:
27
Step-by-step explanation:
Substitute n = - 2 into the expression
n² - 8n + 7
= (- 2)² - 8(- 2) + 7 = 4 + 16 + 7 = 27
Answer:
He missed 10 questions and got 30 right
Step-by-step explanation:
So we could do 0.75 times 40 and we would get 30
So he got 30 questions right which isn't too bad
