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)

Determine the x intercept
To get the value of x intercept; we simply substitute 0 for y;
i.e. y = 0
becomes



Multiply both sides by -1



<em>Hence, the x intercept is 6</em>
Answer:
7/8
Step-by-step explanation:
power of 1/2 is the same as square root.
√(49/64) = 7/8 since 7/8 * 7/8 = 7*7/8*8 = 49/64
The median thickness of the entire glacier is calculated with the arranging the given dimensions of the thickness from least to highest.
29, 34, 35, 36, 38, 40, 41, 43, 44, 46
The middle tern is the 5th and 6th terms which are equal to 38 and 40. Average of this cool is still 39.
