Answer:
The percentage increased by approximately 5%.
Step-by-step explanation:
52.10 - 49.62 = 2.48
2.48/49.62 x 100 = 4.998%
The percentage increase in the price is approximately 5%. Hope this helps! :)
F(x) = 4 [cos (x)]^2 - 3 = 0
4[cos(x)]^2 = 3
cos(x) = √3 / 2
That happens in the first and fourth quadrants, for the angles 30 degrees and 330 degrees.
Answer: x = 30 degrees and x = 330 degrees
-2,2 is the answer hoped it helped :)
The product would be -4984.
