5600 can be simplified. Say you were to just take the two zeros off the end and you would have 56. Now divide 56 by 7 and you get 8. Add the zeros back to the 8 and your answer is 7 x 800. Hope this helps.
The domain of the function is all the values from which the functio can be mapped: here it's between 0 and <span>76,867 -depending on how many people come
</span>
The range is all the values that the function can have.So here it's from 0, when noone is coming, to 76867*161=12377036
Answer:
Step-by-step explanation:
50,000

To find the time in which all the bells ring together, we need to find the LCM of 36,40,48.
Prime factorization of 36=2×2×3×3
Prime factorization of 40=2×2×2×5
Prime factorization of 48=2×2×2×2×3
Hence, LCM of 36,40,48=2×2×2×2×3×3×5=720 seconds.
720seconds=
60
720
minutes=12minutes
Hence, all the bells will ring together after 12 mi
We will check each options and verify it
(a)
![18-2m](https://tex.z-dn.net/?f=18-2m%3C7%2B3m)
we can plug m=2
![18-2\times 2](https://tex.z-dn.net/?f=18-2%5Ctimes%202%3C7%2B3%5Ctimes%202)
![18-4](https://tex.z-dn.net/?f=18-4%3C7%2B6)
![14](https://tex.z-dn.net/?f=14%3C13)
so, this is FALSE
(b)
![7x-\frac{x}{3} >19](https://tex.z-dn.net/?f=7x-%5Cfrac%7Bx%7D%7B3%7D%20%3E19)
we can plug x=3
![7\times 3-\frac{3}{3} >19](https://tex.z-dn.net/?f=7%5Ctimes%203-%5Cfrac%7B3%7D%7B3%7D%20%3E19)
![21-1 >19](https://tex.z-dn.net/?f=21-1%20%3E19)
![20 >19](https://tex.z-dn.net/?f=20%20%3E19)
so, this is TRUE
(c)
![6x-1>4x+5](https://tex.z-dn.net/?f=6x-1%3E4x%2B5)
we can plug x=3
![6\times 3-1>4\times 3+5](https://tex.z-dn.net/?f=6%5Ctimes%203-1%3E4%5Ctimes%203%2B5)
![18-1>12+5](https://tex.z-dn.net/?f=18-1%3E12%2B5)
![17>17](https://tex.z-dn.net/?f=17%3E17)
so, this is FALSE
(d)
![2x^2-3x+1](https://tex.z-dn.net/?f=2x%5E2-3x%2B1%3Cx-%5Cfrac%7Bx%5E2%7D%7B4%7D)
now, we can plug x=2
![2(2)^2-3(2)+1](https://tex.z-dn.net/?f=2%282%29%5E2-3%282%29%2B1%3C2-%5Cfrac%7B%282%29%5E2%7D%7B4%7D)
![8-6+1](https://tex.z-dn.net/?f=8-6%2B1%3C2-1)
![3](https://tex.z-dn.net/?f=3%3C1)
So, this is FALSE
