Step-by-step explanation:
Use double and triple angle identities:
sin(2x) + cos(3x)
2 sin x cos x + 4 cos³x − 3 cos x
She’ll have to make 4 more stitches in order to get 6 good ones. Each time she creates 3 she undoes 2 which after 4 more times would leave her with 6 good stitches.
For the answer to the question above, just <span>use similar triangles.
</span>Here's the equations that I used.
<span>t/h = (x + t) / r </span>
<span>x + t = rt / h </span>
<span>x = rt / h - t
I hope my answer helped you in your problem, Have a nice day</span>
you divide 72 by 2 to get r by itself and get 36
so r=36
Answer:
in (x,y), it becomes (-x,y)
