<span>cos 4x + cos 2x = 2 - 2 sin^2 2x - 2 sin^2 x
cos 4x + cos 2x = 1 + 1 − 2sin^2(2x) − 2sin^2(x)
cos 4x + cos 2x = (1 - 2sin^2(2x)) + (1 - 2 sin^2(x)
cos 4x + cos 2x = cos 4x + cos 2x</span>
Answer:
the answer is the last one. hope this helped.
Step-by-step explanation:
The first picture is 10. how many people were in the sample, unless there is something else that says "for each x counts for however many people) if they each count for 1 it should be 10
median is 8.5
mean is 8
mode is 8
outlier is 5
Answer: the finall statment is true because there are more postive factors than negitive
Answer:
A simple exponential function to graph is y=2x . Notice that the graph has the x -axis as an asymptote on the left, and increases very fast on the right. Changing the base changes the shape of the graph. Replacing x with −x reflects the graph across the y -axis; replacing y with −y reflects it across the x -axis.
