616,000, you just multiply 77*8,000 and then plug it in so 616,000/77
Answer: 26/21 or 1 and 5/21
Step-by-step explanation:
Dividing by a fraction is the same as multiplying by the reciprocal, so you can rewrite this problem as (4/6) x (13/7)
Next, multiply the numerators (4 and 13) and the denominators (6 and 7)
You will get 52/42, which can be simplified to 26/21 (you can also write this as 1 and 5/21)
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
