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
<span>To find the z-scores, find the difference in the number of inches for each value from the mean and then divide that by the standard deviation. For women at 72 inches (6'), this would be (72-64) / 2.7, or a z-score of +2.963. For a male at 72 inches, this would be (72-69.3)/2.8, or +0.964. This shows that the woman at 6 feet tall is more rare in the distribution than a man at 6 feet tall.</span>
Answer:
it is odd i think
Step-by-step explanation:
Answer:
8 x 8 = 64
64 x 6 = 384 ft^2 is your answer.
Answer:Y=-8-2x
Y=-1+1x
Step-by-step explanation:
Solve for y in the second equation
the answer for that should be y= -8-2x and y=-1+1x
then plot both of the equations using rise over one
