Answer:
Step-by-step explanation:
Given that Z the set of integers is the universal set and
A is given in set builder form.
![A = {x | x^2 ≤ 5}](https://tex.z-dn.net/?f=A%20%3D%20%7Bx%20%7C%20x%5E2%20%E2%89%A4%205%7D)
To convert this into roster form, we can find solutions for x
When ![x^2\leq 5\\|x|\leq \sqrt{5} =2.236](https://tex.z-dn.net/?f=x%5E2%5Cleq%205%5C%5C%7Cx%7C%5Cleq%20%5Csqrt%7B5%7D%20%3D2.236)
i.e. all integers lying between -2.236 and 2.236
The only integers satisfying this conditions are
-2,-1,0,1,2
Hence A in roster form is
A=![{-2,-1,0,1,2}](https://tex.z-dn.net/?f=%7B-2%2C-1%2C0%2C1%2C2%7D)
Hi,
I would say that the answer is 28, but it still doesn't add up because when you multiply 12 by 28 you get $3.36 which isn't enough to meet his total, so I tried multiplying 12 by 29 and I got $3.48, which is six cents over his total. So I'm sorry if it is wrong I tried to help to my best ability.
I hope it helps, have a great day/night!!!
Can't really see it, can you show it to me more?
