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:
$0.60
Step-by-step explanation:
The mean is the average. We add up all the numbers and divide by the number of numbers.
The total for 1st week is $12.48+$9.50+$10.25+$4.99+$8.59 = $45.81
Now, the mean:
Mean = 45.81/5 = $9.162
2nd week's total is 3 more than last week's total, so 2nd week's total is:
45.81 + 3 = $48.81
Now, Mean:
Mean = 48.81/5 = $9.762
The increase is 9.762 - 9.162 = $0.60
