5 7/32 = 167/32
5/32 + 5/32 (2 wall thicknesses of the pipe) =10/32
167/32 - 10/32 = 157/32
= 4 29/32
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
<h3>
Answer: 8/3</h3>
Explanation:
Divide the image length over the pre-image length to get
24/9 = (8*3)/(3*3) = 8/3
The scale factor is 8/3. This means the image is 8/3 times longer compared to the pre-image.
