1/40 = .025, just multiply this by 21 and you have your answer
.525
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
Answer:
x=105 and y=190
Step-by-step explanation:
4x+1y=610, and x+y=295 ; x= 105 and y=190
