Answer:
8
Step-by-step explanation:
Using the identity
cosec²A = 1 + cot²A
- 8cot²A + 8cosec²A
= - 8cot²A + 8(1 + cot²A)
= - 8cot²A + 8 + 8cot²A
= 8
$2.35 to buy lunch at school for 9 days
so you take 2.35 and multiply it by 9
you get 21.15
2.35 x 9 = 21.15
therefore he spent 21.15 in 9 days
You must divide the larger by the smaller... That will give you the scale factor.
For example: Rectangles 10 x 20 and 5 x 10
the scale factor us 10/5 = 20/10 = 2
Hope this helps.
