Step-by-step explanation:
Sin^2 (x) * Cos^2 (x) = {[1 - cos (2x)]/2}*{[1 + cos (2x)]/2}
Sin^2 (x) * Cos^2 (x) =[ 1 - cos^2 (2x)]/4
Sin^2 (x) * Cos^2 (x) = (1/4) - (1/4) * cos^2 (2x)
Sin^2 (x) * Cos^2 (x) = (1/4) - (1/4) * {[1 + cos (2*2x)]/2}
Sin^2 (x) * Cos^2 (x) = (1/4) - (1/8) * [1 + cos (4x)]
Sin^2 (x) * Cos^2 (x) = (1/4) - (1/8) - (1/8)* [cos (4x)]
Sin^2 (x) * Cos^2 (x) = (1/8) - (1/8)* [cos (4x)]
Answer:
Step-by-step explanation:
8x+9/x^2-13x+42
Write 8
x as a fraction with denominator 1
8x+9/x^2-13x+42
then we multipuly 8x/1 by x^2/x^2
Answer: If i was living there usually , The climate in Ancient Greece generally has hot summers and mild winters. Because it can get so hot, most people wore lightweight clothing throughout most of the year. They would put on a cloak or wrap during the colder days of the winter months. The environment would make a HUGE impact on the Greeks by teaching them how to collect food and survive in a harsh environment. Therefore, I would have to adapt to adapt to their environment efficiently. The environment also affected them because they had to learn to fish instead of hunt on
Step-by-step explanation: This is how I would do it.
Answer:
3m = -3
Step-by-step explanation:
You are given
2m - 6 = 8m,
hence,
2m - 8m = 6,
-6m = 6,
m = 6%2F%28-6%29,
m = -1.
Therefore, 3m = -3.
Answer:
7.45
Step-by-step explanation:
We are given a right triangle with one side length known and an angle know so we can use some trigonometry.
You need to find the hypotenuse so you are going to use either sine or cosine.
Since the adjacent from the angle is given (SOH-CAH-TOA) we can use cosine so,
cos(20) = 7/h
=>h = 7/cos(20)
=> 7.44924
=> 7.45
