Answer:
14,500
Step-by-step explanation: Just took the test.
Answer:
A) 0.50x +300 < 650, where x < 700
(Please mark brainliest. :3)
Cos² 2x = (1+cos 4x )/2
cos² 6x = (1+cos 12x)/2
subtract to get 1/2 (cos 4x - cos 12x )
= 1/2 (2 sin 4x sin 8x ) as cos A - cos B = 2 [ sin (A+B)/2 sin (A-B)/2 ]
so the answer
Answer:
16/5 or 3.2
