Answer:
Step-by-step explanation:
She would use 25 quarters which would make $6.25. And she would use two pennies.
Sin^2 (2x) = (1 - cos(4x))/2
---> sin^4 (2x) = (1/4)(1 - cos4x)^2 = (1/4)(1 - 2cos4x + cos^2 (4x)) and replace cos^2(4x) by (1/2)(1+cos(8x)) --->answer
12. Suppose U= {1, 2, 3, 4, 5, 6, 7, 8} is the universal set and P= {1, 2, 3, 4]. What is P'? (1 point)

Answer:
o {5, 6, 7, 8}
Step-by-step explanation:
To find<em> P'</em>
P' = U - P
P' = {1, 2, 3, 4, 5, 6, 7, 8} - {1, 2, 3, 4}
P' = {5, 6, 7, 8} ANS.
